COVID-19, GIS, Mapping

Feeling the COVID-19 travel blues? Dispel it by mapping your favorite locations around the world.

My youngest daughter, who insists that she is no longer a baby, made up her very own song about COVID-19. It is shared below for your listening pleasure. Even the youngest among us are aware of COVID-19. That to me signifies the impact that has had on life as we knew it.

The Covid-19 Song

For the past few months all that we have been hearing about is the COVID-19 pandemic and the restrictions it has placed on us all. Now with many borders being closed, and travel restricted to many destinations, I find myself thinking about the places I have been around the world. My most memorable places turns out to be where I have been, in relation to my learning about geospatial technologies. Listed below are my 7 most memorable places and an indication of the “GISsy” things I learnt when I visited.

  1. Dehradun, India – Remote Sensing and Digital Image Processing
  2. A Coruna, Spain – QGIS software training
  3. Chaing Mai, Thailand – Emergency Response
  4. Stanley, Falkland Islands – Spatial Data Management
  5. Merida, Mexico – Marine Spatial Planning
  6. Valetta, Malta – Coastal Resource Management
  7. Belmopan, Belize – Census Mapping

This trip down memory lane convinced me to create a simple map to document these memorable places. Shown below is the dynamic map I created. You can explore this map by zooming, panning and clicking on my location markers. I added images of each location that remains been etched in my mind from my visit.

COVID-19: Using Geospatial Resources to Understand the Potential Impact on Our Communities.

On Tuesday March 17, 2020 with a cancelled celebration of St. Patrick’s Day, Montserrat received the dreaded news of its first confirmed case of novel coronavirus COVID-19. For many of us that is when the gravity of this situation hit home, literally!

The Ministry of Health and Social Services (MoHSS), in their press release (, reminded members of the public to adhere to the following risk mitigation measures:

  1. Refrain from public gatherings
  2. Maintain social distance and
  3. Wash hands regularly with soap and water or using a hand sanitizer.
  4. Limit non-essential travel

In addition, to the guidelines provided above, the utilization of geospatial services and resources can help prepare, manage and deliver an effective response to COVID-19.

President of Environmental Systems Research Institute (ESRI), Jack Dangermond in a letter addressed to its users, highlighted some steps that can be followed in order to understand the potential impact that COVID-19 can have on our community. Five are outlined below:

  1. Map the Cases – map confirmed cases, deaths and recoveries in order to identify where COVID-19 infections exist and have occurred.
  2. Map the Spread – Time enabled maps can reveal how infections spread over time and where interventions can be targeted.
  3. Map Vulnerable Populations – Mapping factors such as social vulnerability and age can help monitor risk groups
  4. Map Capacity to Respond – Map health facilities, medical resources and employees to understand and respond to potential impacts of COVID-19.
  5. Communicate with Maps – Use interactive webmaps, dashboard apps and story maps to help communicate the situation.

Communication with maps have already been used worldwide to map COVID-19. Webmaps, dashboards and story maps help to visualize the evolving situation.

The dashboard app below, powered by GeoTechVision ( shows the COVID-19 outbreak worldwide. It highlights infections, fatalities and most importantly recoveries.

The story map below details the origins of COVID-19 and gives an account of its geographic spread in an easy to read interactive dialogue.

Communication through map-based dashboards and story maps such as these offers accessible information to people in our communities and around the world eager to protect themselves. These tools improves data transparency and helps authorities disseminate information quickly and effectively.

Electric Vehicles, GIS, Mapping, Spatial Analytics

How GIS is being used to help alleviate “range anxiety” in the use of Electric Vehicles (EVs)


The first fully electric car was unveiled in Montserrat on August 16, 2019.  A truly historical moment which has been captured and shared on this youtube link by Montserrat's Government Information Unit:

At the unveiling ceremony, a number of discussions surrounded the length of time that a fully charged battery would last and whether or not the electric vehicle (EV) would be able to traverse the winding, steep roads of Montserrat (case in point, Forgarthy Hill) on a full charge.

I have recently come to the understanding that this mindset is referred to as “range anxiety”.

The Oxford Online Dictionary defines range anxiety as “worry on the part of a person driving an electric car that the battery will run out of power before the destination or a suitable charging point is reached”. It has been further noted that this is one of the major hindrances to large scale adoption of all-electric vehicles (

Four major strategies have been implemented to alleviate range anxiety among electric car drivers:

  1. The development of higher battery capacity at a cost effective price
  2. Battery swapping technology
  3. The use of range extenders
  4. Accurate navigation and range prediction

The utilization of Geographic Information Systems  (GIS) however, and its capability to employ multi-criteria location analytics, provides a solution which would help to alleviate range anxieties for electric car users. Moreover, these tools can assist decision makers in developing a strategic plan for the establishment of a well distributed electric vehicle charging station infrastructure.

In identifying optimal geographic locations for new electric vehicle charging stations, a number of factors should be considered.

  1. Location of likely users of electric vehicles. This can be determined by utilizing census data which contains information on age groups and socio-economic information.
  2. Locations which are high attraction venues to the public. This includes identifying the location of places where persons tend to spend a great deal of time such as, airports, ferry ports, government offices, health care facilities, libraries, places of worship, schools, supermarkets and rum shops.
  3. Availability of GIS data based on appropriate themes - Information contained in datasets such as digital elevation models, land use maps, road networks are pertinent in conducting this type of location analysis.

The output would be a map which displays varying degrees of suitability for the most appropriate locations to install charging stations.

Overall, Electric vehicles (EVs) are both economic and ecological vehicles, since they get their power from rechargeable batteries inside the car. They are advertised as zero emission vehicles, less noisy and more cost effective in the long run.

With the utilization of GIS and location analytics, the main disadvantage of recharge related problems will be curtailed, as vehicle charging stations would be carefully located to maximize electric vehicle usage. The end result would be the reduction in range anxiety of its users.

To put the icing on the cake, it would be absolutely amazing if these charging stations can be fully powered by a source of renewable energy, such as, solar, wind, hydro or geothermal. Then we would be truly making strides to saving our planet!

GIS, Mapping, Volunteering

Becoming a MapAction Volunteer

When the call came for Caribbean volunteers to apply to MapAction, I was keen to sign up. Having followed the work of this organization and the amazing group of persons who work as volunteers, I saw this as an awesome opportunity for me to contribute to the work of saving lives.

MapAction is a non-governmental, UK based charity, that specializes in providing mapping for humanitarian emergencies. MapAction has the ability to quickly gather crucial data and convey it visually, in the form of maps.  With MapAction’s support, aid agencies, governments and local partners, are in a better position to make informed decisions to deliver aid and emergency supplies to the right place, quickly.

Living in Montserrat, with an active volcano and being privy to how devastating disasters can be, I was grateful for the prospect of being able to use my skills in geospatial technologies to contribute to humanitarian efforts during a disaster. My mind quickly raced back to the impact Hurricanes Irma and Maria had on my neighboring Caribbean Islands, in 2017. I wanted to be in a better position to offer assistance if a situation like that – God-forbid – presented itself again.

I therefore, submitted an application to the organization and not very long after, I was greeted with an email inviting me to an “Assessment Day“. Needless to say, I was very happy to advance to the next stage.

Assessment Day turned out to be very interesting. Surprisingly, during the introductory session, I was reintroduced to the Head of the MapAction Caribbean Section, who reminded me, that we met, while he visited Montserrat in another capacity several years before. Moreover, the gentleman who is the Preparedness Lead for MapAction worked in Montserrat briefly on a project back in the early 2000s. I found it to be very fascinating how unsuspectingly our paths crossed again! In addition, hearing the testimony of a fellow MapAction Volunteer, sort of sealed the deal for me. He explained what being a volunteer all entailed and how my skills can contribute to saving lives.

Overall, this interview process was detailed enough to ensure that I was a good fit for MapAction. Amongst other skills, the panel assessed team spirit, leadership potential and the knowledge and application of Geographic Information Systems (GIS) tools and software.

Receiving another email shortly after assessment day, entitled, “MapAction Caribbean Section – Interview Outcome”, I nervously, but anxiously opened it. The words that bounced from my computer screen, read:

Congratulations, you have been selected to join our Caribbean Team! 

This was awesome news and I am absolutely thrilled to be apart of the MapAction family and being able to contribute to society in this capacity.

I look forward to sharing more about the work of MapAction and my experiences in future blogs.

What is GIS?

Learning to read, my youngest daughter looked at her dad proudly as she shouted out the letters on his T-Shirt…“G I S!”. Then she looked at me inquisitively and said “Mommy, G I S?” I responded in the affirmative, “Yes sweetie, G I S!”

So, what is GIS?

This picture which I captured on my return flight to Montserrat, overlooking Davy Hill and Little Bay will help me to explain.

View overlooking Davy Hill and Little Bay, Montserrat

At first glance, buildings, roads, vegetation, hills and the ocean can be seen in my picture. GIS, which stands for Geographic Information System allows you to capture, store, manipulate, analyse, manage and present, this type of geographic data.

The unique aspect about GIS is that it allows you to store additional information, called “attributes”, about each feature. For example, attributes of a road may include its name, type, whether primary or secondary and its length. Similarly, attributes of a building, may include the owner’s name, a category of use, whether it is residential or commercial, the material that the building is made from, for example, wood or concrete, the roof type and also the number of floors.

Attribute data can be obtained from a number of sources or data can be captured specifically for your application. Spatial data can be obtained from satellite images, aerial photographs, scanned maps and similar resources. Essentially, any format of a geographical image with location or co-ordinate points can be used as spatial data.

The combination of spatial and attribute data gives GIS the capability of providing answers to complex questions. It is undeniably, the partnership of these two data types that enables GIS to be such an effective problem solving tool through spatial analysis.

To visualize large amounts of information interactively is one of the most attractive and useful capabilities of GIS. To do this, data is extracted and stored in the form of “layers”.  The image below captures graphically how these layers relate to the real world.

                           Representation of layers in GIS

GIS utilizes two primary data types: vector and raster. Vector data is represented as either points, lines, or polygons. So let’s go back to my picture of Montserrat. In that picture, the location of a particular facility, such as the new location of ZJB Radio in Davy Hill can be captured as a point, other buildings can be represented as polygons, along with the entire settlement area of Davy Hill and the roads can be captured as lines.

Contrastingly, raster data is best suited for information that does not have hard boundaries or locations. So again, let’s revert to the picture which I took. The hills and valleys which you can see are best represented as elevation or terrain modelling surfaces. Raster data is usually used to represent this type of data in a GIS. Data in rasters are viewed as a series of grid cells where each cell has a value representing the feature being observed. 

Unlike, traditional paper maps, GIS is fully interactive. It allows you to add new fields of data,  change the color scheme or form of the map, add text and move symbols around. GIS displays allows you to zoom and pan which offers new perspectives and new insights. These and a host of other capabilities give a user tremendous flexibility and power.

GIS is more than just software. It is a system where trained people and methods are combined with geospatial tools, to enable spatial analysis, manage large datasets, and display information in a graphical form.

Counting the Population is as Easy as 1, 2, 3 with the Help of GIS


My three year old is fascinated with counting. Probably one of the most memorable instances of her enthrallment was her sounding off “1, 2, 3, 4” as a family of sisters occupied the bench directly behind us in church. “Four, Mommy, Four!” she shouted as she also pointed it out on her fingers. Seen from my toddlers enthusiasm, there is an innate nature in all of us to know “how many?”.

Conducted on average, every 10 years, the purpose of a census is to gather information about a population’s housing conditions, demographics, social and economic characteristics. It includes collecting data like age, gender, education and employment. It helps us to answer questions like: how many children in your country have completed secondary education? Or how many 20-year olds who live in a particular area and are unemployed? Or how many people in total live on your island? Basic information, such as these, are important for the purposes of planning, development and the improvement in the quality of life for a territory’s citizens.

Counting the population of any country, regardless of the size, can be seen as a daunting task. Geographic Information Systems (GIS), provides a platform, however, to enable data collectors to be more efficient in locating buildings and ensuring that this intimidating work is made a lot more manageable.

In its last count of the population, the Montserrat Statistics department enlisted the use of GIS in the Montserrat 2011 Population and Housing Census to ensure that the enumeration data collected was as accurate as possible. Some visual representations of the data were produced, such as the map below which shows the usual resident population of 4,922 based on gender (male and female) and region (northern, central and southern).


The leader* and the team from the statistics department had a clear vision of how the country should be divided in terms of Enumeration Districts and Areas. Some areas were demarcated using naturally occurring features on the landscape, such as ghauts and mountains, and others were demarcated using man-made features like roads. A total of thirty-six enumeration areas were created and detailed maps were prepared for each area. This allowed the areas to be divided into manageable sections and allowed the data collector, with training in map reading, to be more efficient in canvassing the area. The demarcated enumeration areas now provide a base for the collection of additional data and allows for easy comparison and correlation of datasets in preparation for the 2020 round of censi.

The Montserrat 2011 Population and Housing Census benefited from imagery, which was recently collected in 2010 (see my previous blog at  The one-year time difference was considered negligible, allowing for a certain level of confindence in the accuracy of the maps, which were produced. Any missing building footprints were drawn on the map while the area was being canvassed, and then later updated. For any future census activity, access to current imagery will play a huge role in its success. Current imagery can be analysed using tools in GIS which will help to determine changes since the last count. One special way of determining change is to use image classification techniques and compare with previous imagery. Utilising this method, new buildings footprints can be identified and quickly extracted using GIS tools and models.

Furthermore, a census provides data, which is critical for disaster risk reduction. Knowing the spatial distribution of the population and its demographic details is key in increasing a Government’s ability to take appropriate action and reduce the loss of human life. Population density maps provide an outlook to assess risk before and the quantification of a population affected after any disaster.

*This post pays tribute to the late Mrs. Katrina Ryan who was the head of the Statistics Department at the time of the Montserrat 2011 Population and Housing Census in Montserrat. She had an endearing passion for the accuracy of statistical data. May her soul rest in eternal peace.

Satellite Imagery is A Powerful Visual Aid in GIS and Disaster Response

The earthquake events of August 21, 2018 which shook Venezuela, Trinidad and other neighbouring countries ( reminded me that not all disasters can be predicted or come with a warning. Videos which showed the impact of the earthquake quickly filled my social media timeline, causing me to reflect on the training I had undergone as project manager for the International Charter Space and Natural Disasters ( This organization, once registered with, provides a series of support through the use of satellite imagery to assist in the aftermath of a disaster.

Satellite imagery is a form of remotely sensed data with proves useful in the occurrence of an unforeseen event and provides a powerful visual aid when utilized with a geographic information system (GIS). Disaster risk managers are better able to assess their region’s risk when they are able to compare pre and post disaster images.  This type of analysis enables relief workers to identify changes in the landscape, such as buildings which are no longer standing and roads which are obstructed. It is an efficient way to identify damage and conduct rapid impact and needs assesments. GIS supports the use of satellite imagery to locate damaged facilities, identify the type and amount of damage and begin to establish priorities for action.

As satellite sensors improve, satellite imagery is becoming more useful. One of my favourite places to explore satellite data is the USGS Earth Explorer Portal ( It provides an interface where one can search the available sensors to see the data that is available for a particular area of interest. The advantage of the USGS Earth Explorer is that it houses data from the Landsat Programme which has a 40+ year track record of image acquisition. It allows for free downloading of data over chronological timelines while providing a long list of satellites to choose from.

Additionally, capturing my interest for hours on end is the USGS Earth Now Viewer ( This viewer is truly remarkable as it shows the position of the Landsat sensor in real-time. It also gives a visual of the satellite images being collected when the sensor scans the earth.

The Landsat Program began with Landsat-1 in 1972 and Landsat- 9 is planned for 2023. Over the years, Landsat has enhanced the number of spectral bands, spatial resolution and spectral resolution. Landsat 1-3 sensors collected data in only 4 bands and at 60 meter resolution. Over time, this has improved, as Landsat 8 now collects in 11 spectral bands varying from 15 meter to 100 meter.

The Sentinel Satellites of the Copernicus Programme also provide free satellite imagery which can be downloaded at the Copernicus Open Access Hub ( The Sentinel-2 provides some improvement to the Landsat data with sharper imagery of up to 10 meters. Sentinel-2 monitors more frequently with a revisit time of 5 days and captures land changes in 12 spectral bands, each ranging from 10 – 60 meters pixel size. The USGS Sentinel2Look Viewer ( allowed me to browse through some sentinel-2 imagery. I found relatively cloud free imagery of Montserrat (shown below) which was acquired on 12th April 2018. This is a plus as cloud-free imagery is not always available due to our location and climate.

With the assistance of a skilled technician, satellite imagery can be utilized effectively in disaster management especially during the response stages. By combining spectral bands and performing image classification techniques the capabilities of remotely sensed data can be fully utilized in disaster management.

Drones: Four reasons to use them in GIS and Mapping


I remember May 2010. Not only because it was the last time since the Montserrat Soufriere Hills Volcano’s dome collapsed, triggering a pyroclastic flow which completely covered the remnants of W.H. Bramble Airport. I remember May 2010 because I rode shotgun in a unique airplane.

This was an airplane which had a hole in the underside of it. Mounted and fitted in the hole was a camera. Not just any camera, it was a camera with unique specifications, designed for taking aerial photographs. After monitoring the weather for days and looking for a “space in the clouds” as it was termed, the mission began by travelling over to the neighbouring island of Antigua. I recollect that on the day of the flight we had to have all hands on deck, pushing the plane out of the hanger.



The flight plan was scribbled on a piece of paper, which the pilot displayed in front of him for the duration of the exercise. Riding shotgun, I took in the amazing vista of being up and above my beautiful island of Montserrat. We flew in an easterly to westerly pattern, for a number of days covering the island with images from the sky. The technician constantly gave instructions to the pilot to ensure that we were having a certain percentage of overlap in the images as they were being taken. Furthermore, the post-processing of the images was a lengthy one, as they had to be cleaned, corrected and geo-referenced in order to be used appropriately. After about six (6) months we finally had the complete set of imagery in our hands.

So much has evolved in eight (8) years. Aerial photographs are now been captured by Unmanned Aerial Vehicles (UAVs) or Unmanned Aerial Systems (UASs) commonly known as drones.

Here are four (4) reasons why I think drones should be used in Geographic Information Systems (GIS) and mapping:

Reduction in Cost – Drones provide a less costly way of acquiring remotely sensed data than the traditional method of a plane and pilot. There would be no need to need to hire a skilled pilot and pay exorbitant fees for the use of an aircraft and rental of a hanger, if drones are used. Drones provide an acquire once, use many times option, thereby significantly reducing cost.

Reduction in Risk – Although I thoroughly enjoyed the vista and scenery provided from the plane, there was an evident risk to human life. As the term “unmanned” suggests, drones reduce the risk to human life, as there is no man on-board. Moreover, drones do not possess human characteristics of becoming tired or getting distracted. These qualities do prove advantageous when collecting large amounts of data.

Reduction in Time – Drones provide a significant reduction in the time taken to acquire the imagery and the time taken to process the acquired image. Instead of taking months to see the output of one’s work, this is made available instantaneously as the data is being captured. Adjustments can also be made while flying, because the data can be visualized as it is being collected. Drones nowadays come equipped with global positioning systems (GPS) which allows for autonomous flying of pre-planned flight paths, thereby saving time in the field.

Increase in Quality – The output of drone images are becoming increasingly better. Drones can get closer to a scene than a plane can, thereby allowing for greater quality and detail in the imagery which is being captured. Appropriate specifications for the camera which is mounted on the drone, is key.

As reported, about a week after the May 3rd 2018 eruption of Hawaii’s Kilauea volcano, drones were deployed and started flying over the widening lava flows. This is thought to be the first time drones were being used to capture critical images and data above a volcano during emergency response efforts. (

Utilizing newly acquired information and comparing it with pre-disaster information, gives a clear understanding of what transpired. Imagery collected from drones becomes a powerful resource once it is fed into a GIS. In emergency response situations, drones provide a quick overview with reliable visuals without putting first responders at risk.

Five (5) things GIS has taught me about Disaster Management

I am no stranger to the impact of disasters having survived Hurricane Hugo in 1989, and witnessed the Soufriere Hills Volcano disrupt everything I knew about life in Montserrat since 1995.

As I listened to the reports on the experience of our neighbouring islanders who were affected by the super hurricanes of 2017, Irma and Maria (which I now simply refer to as IRMARIA), I empathized.  Now as I watch reports of the experience of the residents of El Rodeo, Guatemala in dealing with the eruption of Volcan de Fuego which erupted on June 6, 2018, I am driven to share a bit of how my work can help countries manage disasters better.

Geospatial technologies have improved in recent years and are more efficient and reliable to enhance our planning, mitigation, preparedness, response and recovery from disasters.  The majority of data needed for these phases of emergency management is spatial, and once it is spatial it can be mapped and utilized effectively.

Over the years, Geographic Information Systems (GIS) has taught me a few things in relation to disaster management. Here are five (5) of them:

1.       Most emergencies don’t allow time to gather information.

2.       During an actual emergency there is no time for guessing or estimating, it is critical to have the right data, at the right time.

3.       Lack of appropriate information leads to poor planning and poor decision making.

4.       GIS provides a mechanism to centralize and visually display critical information during an emergency.

5.       GIS saves time, money and lives!

The road to recovery is often very difficult for anyone faced with loss after the impact of a disaster. Many of us on Montserrat however, built up our resilience as we reflect on the loss of homes – not just houses. We have embraced the challenge of recreating the places we lost. Unbelievably,  the Government Headquarters building in Plymouth was newly constructed and the Glendon Hospital was newly refurbished at the time of the eruption. Personally, I often reflect on the town centre which was thriving and bustling as it created jobs, enhanced livelihoods and held memorable spaces, such as “Evergreen Tree” and the “market” for social interaction.

A specialism in GIS allowed me the opportunity to support recovery efforts by utilizing data and producing maps that helped to manage evacuation paths, relocate families safely to shelters, assist in ash clean-up efforts by tracking progress and by utilizing the output of modelling scenarios to identify future impact areas.  GIS provides a mechanism to forge ahead and recover despite the impact of a disaster. Montserrat is now in a phase of re-development and GIS has contributed significantly to this. I do look forward to telling you more about how GIS can be used in disaster management.
