Assessing and Responding to the Beirut Blast through the Use of Imagery and Mapping Techniques

My colleague turned his phone to me and said, “Have you seen this?” Thinking that it was just another funny video created by one of the many internet users who are currently in lock-down due to the COVID-19 pandemic, I braced myself. This time however, it was no joke!

On August 4th, 2020, a warehouse at the Port in Beirut, Lebanon, storing approximately 2,750 tonnes of ammonium nitrate, exploded, destroying nearby buildings and causing damage miles away.

Compare the images below by moving the slider. They show images pre-event on June 9, 2020 and post-event on August 5, 2020. In the image the port warehouses, and the grain silos can be seen. The destruction of the 120,000-ton capacity structure of the grain silo and disabling of the port, the main entry point for food imports, exacerbates concerns about food supplies for Lebanon.

Coincidentally, during my university days in Edinburgh, Scotland, I shared a flat with two amazing ladies who I grew very close to during my year abroad. Thankfully, I still maintain close contact with them, although it has been more than 16 years since we first met. One of them is from Lebanon and the other from Cyprus. Instinctively, upon realizing the severity of the situation that I witnessed in that video, I reached out to them both. My friend from Lebanon, now resides elsewhere. She indicated however, that many of her family members suffered damage to their homes. My Cypriot friend mentioned that they heard the explosion all the way in Cyprus and that it even felt like an earthquake!

Pictured below is a map showing the proximity of Cyprus to Lebanon, an approximate 265 km distance. I couldn’t help but think of the safety of my friends and their families.

As a member of the humanitarian mapping charity – MapAction, I was thankful to learn that a 3 member group was being deployed to help! Even with the rising challenges of operating during the COVID-19 pandemic, this organization, as well as many others are ready to offer support in crisis.

Responding to the Beirut explosion

After being given the opportunity to attend an International Search and Rescue Advisory Group (INSARAG) Earthquake Response Exercise (ERE) in December 2019 in Thailand, I have a deeper understanding and appreciation for the need of collaboration and communication between the teams that are on the ground responding to a disastrous situation. MapAction supports this effort by providing maps to help with co-ordination. The map below shows that in Lebanon, there are several teams on the ground, to include Urban Search and Rescue (USAR), United Nations Office for the Coordination of Humanitarian Affairs (UN OCHA) and the Red Cross. It is quite helpful when co-ordination locations are known by all the teams on the ground.

This is another map that has been provided by MapAction. It shows the area being divided up into more manageable sectors. The locations where bio hazards exist, have been identified and highlighted on the map.

During the past few days, many satellite imagery companies have offered their support to Beirut. This offering is welcomed, as it helps teams on the ground to conduct further damage assessment and provide service delivery to those in need.

The Disasters Charter has also been activated to respond to the Beirut blast. Though clouds obscure parts of this image taken via a Pleides satellite sensor, the map shows emergency shelters being set up, and highlights the location of hospitals in the area.

It is my hope and prayer that Lebanon receives the much needed support and humanitarian relief it requires in the aftermath of this disaster. #prayforlebanon

In my previous blogs I have indicated the importance of up-to-date imagery in responding to a disaster and also what led me to becoming a MapAction Volunteer. You can read them below:

My career in GIS was subconsciously influenced 25 years ago by the eruption of Soufriere Hills Volcano

July 2020 marks the 25th anniversary of the eruption of the Soufriere Hills Volcano on Montserrat and presents an opportune moment for reflection.

I was only 13 years old at the time, but I do remember the chaos surrounding these events. It was a very uncertain time for those of us living in Montserrat. At the time I attended the Seventh-day Adventist School in Delvins. I remember exiting the classroom and looking up towards the heavens, like many of my peers. The sky was very dark that day, no one seemed to know what was happening. The picture below is symbolic of what has been etched in my memory.

Emission of ash from Soufriere Hills Volcano, Montserrat
https://www.bgs.ac.uk/discoveringGeology/hazards/volcanoes/montserrat/ash_and_mud.html

I remember the hustle and bustle of parents coming to collect their children. Unfortunately, some of us never had the opportunity to attend school in Montserrat ever again and our childhood friendships and dreams of experiencing life together on Montserrat were dismantled. My mother thought it best to send myself and my brother to live in Antigua with my Aunt because of the uncertainty with schooling and living in Montserrat. Now being a mother myself, I understand her decision.

Just as we began settling into the new norm of life in Antigua, Hurricane Luis, a powerful category 4 hurricane, hit Antigua on September 5th, 1995. This hurricane disseminated the country of Antigua causing damage and destruction to 45% of the residences on Antigua as it passed near 30 miles (48 km) to the north of the island. A recount of Hurricane Luis by Mr. Dale Destin can be found https://268weather.wordpress.com/tag/hurricane-luis/. This storm basically flattened many homes in Antigua, and my Aunt’s home was no exception. Thankfully, to meaningful friendships, my Aunt was able to find accommodation for us and her family elsewhere. So many additional complexities came about from these developments. For example, I remember having to attend school on a shift basis (interestingly, similar to my daughter’s experience during the COVID-19 pandemic now) and spending many nights studying by flashlight and candle light in order to fulfill the requirements for the next day of school.

Although, I was out of Montserrat physically, Montserrat was constantly on my mind. We were always tuned in to ZJB radio to keep abreast of any updates and mostly because my mother was still on island. As a matter of fact, she never migrated!

My brother graduated from secondary school in Antigua in June 1997, and it was around this time that our capital, Plymouth was buried under pyroclastic flows (pictured below). There was no way, that my Mom was going to allow him to go back home. I believe that she was scared even for her own safety! I started thinking about whether or not I will ever be able to identify areas in Plymouth again. Such a tragedy!

After I graduated secondary school in Antigua in a year later, there was still uncertainty in Montserrat. My Mom admonished that it was not the ideal time to return and encouraged me to use the opportunity to continue on to tertiary education. So I ventured even further away from home to pursue a 4 year Computer Science degree in Trinidad. Based on the ongoing situation in Montserrat, I opted to take summer courses which resulted in me completing my degree earlier. Foremost in my mind was how I could make a meaningful contribution to my island home.

I returned home after University graduation in 2002. I was pleased that so many new homes had been built in the north of the island and although businesses were scattered throughout the northern area, things were returning to some sense of normalcy.

I remember having the opportunity to discuss GIS with a consultant who was visiting Montserrat to conduct training. He explained that it was a relatively new field of technology, but it can be used for disaster management along with many other things. He encouraged me to research, applying my knowledge of my recently earned degree to this emerging science.

I delved in, and the rest is history! I completed a Master’s degree in GIS within 3 years of being introduced to the topic. My research topic centered around the “Integration of Remote Sensing Techniques and GIS to Detect and Update Changes in Land Cover as a Result of Intra-island Migration on Montserrat.” Being able to apply my knowledge of GIS to the redevelopment of Montserrat and further assist in disaster management on island, has been my motivation. In retrospect, I can truly say that the eruption of the Soufriere Hills volcano 25 years ago, has influenced my career in GIS to date.

Post Script:

I want to say a hearty thank you to my Mom, who sacrificed everything and ensured that I had a Montserrat to come back home to! I love you Mommy!

Mommy and I.

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 (http://www.gov.ms/first-case-of-new-coronavirus-covid-19-confirmed-in-montserrat/), 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 (https://www.geotechvision.com/) shows the COVID-19 outbreak worldwide. It highlights infections, fatalities and most importantly recoveries.

In an effort to amalgamate information related to COVID-19 in one location, the Government of Montserrat created the Montserrat Coronavirus Response Data Hub: https://montserrat-covid-19-response-data-hub-montserratgis.hub.arcgis.com/. Within the site there is also a dashboard which gives relevant data on the current covid-19 statistics for the island.

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)

Range-Anxietycropped

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: https://www.youtube.com/watch?v=LjENIlHGWBI&feature=share.

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 (https://www.lexico.com/en/definition/range_anxiety).

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.

GIS Day is celebrated annually, read more in my previous blog: https://lavernrogersryan.com/celebrate-gis-day-annually-and-dont-forget-the-cake/.

Celebrate GIS Day Annually and Don’t Forget the Cake!

Since my introduction to Geographic Information Systems (GIS)  some 15 years ago, GIS day is one of those days that I look forward to annually. GIS day is usually on the Wednesday of Geography Awareness Week in November.  It is the one day set aside to show how geographic intelligence touches everyone and provides excellent forum for users, like myself, to showcase unique GIS accomplishments.(See my previous blog –  Counting the population is as easy as 1, 2, 3 with the help of GIS).

This November, (November 14, 2018) hundreds of organizations from North America, South America, Europe, Africa, Asia, Australia and the Caribbean will be hosting gatherings that will serve to ignite the imagination of the future geospatial innovators who will move our planet forward using GIS.  All registered users who will be hosting an event for GIS day 2018 is displayed on www.gisday.com. It is indeed a global event.

Users in the Caribbean region are joining in as well.  Bahamas, Turks and Caicos, Jamaica and Trinidad have already registered their events.

Montserrat is no exception. Our event is registered too!

In the past, to add to the sweetness of this event we have often added a cake to the celebrations.  Here are a few pictures of the cakes we have had to celebrate GIS day in Montserrat over the years.

Now there is absolutely no reason not to love GIS day! Find an event close to you and use the opportunity to learn more about this exciting technology and its amazing capabilities.

 

 

 

 

Disaster Risk Reduction, GIS, Imagery, Mapping

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.
