Over 50 authors, including two MapAction team members, have contributed their expertise and insight about working in health emergencies to a new handbook for humanitarian professionals.

Spearheaded by the Robert Koch Institute, In Control: A Practical Handbook for Professionals Working in Health Emergencies Internationally is aimed at preparing and supporting those deploying internationally during humanitarian crises.

Addressing the multi-faceted challenges of an international deployment, the book provides technical medical information as well as insights into the challenging environments volunteers often work in and the cultural differences that influence risk communication.

The book is divided into two halves, with the first providing an overview of the international architecture and inter-disciplinary environment within which health emergency responses occur. These include the organisations, principles, frameworks and themes that every health professional deploying aboard should be aware of. The second half of the book provides practical advice to help professionals survive and thrive during their mission. Chapters include how to prepare for a deployment, such as arrangements that should be taken care of ahead of departure, and suggestions on what to pack.

Information management & visualisation

As part of their contribution (starting at page 200), MapAction’s Matt Sims and Alan Mills shared how important data visualisations are in making well-informed decisions and the importance of identifying information gaps to ensure those who may need assistance are not overlooked.

Also covered in their chapter are the questions that responders should be asking themselves when handling data, such as whether it identifies the location of vulnerable individuals or groups; how the data is stored and protected; and what will be produced from the data, among other considerations.

What does ‘Data’ mean to MapAction?

What is MapAction’s ‘humanitarian data landscape?’ At MapAction, we’re working to put data at the centre of how we provide products and services to the humanitarian sector. MapAction’s data scientist, Monica Turner, recently posted  about the work she does in this new role. However, data is a big (and sometimes loaded) term. So what does ‘data’ mean to MapAction? We asked Hannah Ker, MapAction’s Data Scientist whilst Monica is on maternity leave, to explain. 

During a humanitarian crisis, it is vitally important for responders to have information such as which areas are most affected, where vulnerable populations exist and where relevant infrastructure & services (such as healthcare facilities) are located. MapAction provides information products (such as maps) to our partners to help them address these information needs. Unsurprisingly the vast majority of data that we work with at MapAction is geospatial. We aim to use geospatial techniques, such as cartography, to make complex data rapidlly accessible to those responding to humanitarian crises.

The ‘Layers of data’ page (see diagram below) from our Example Product Catalogue provides a useful framework for thinking about how many different datasets are processed and combined into a meaningful final product.

Firstly, we can think of the data that is input to our basemap or initial reference map of a given area. This data often reflects features such as administrative boundaries, land elevation, settlements, and transportation infrastructure. Secondly, we have baseline data that provides demographic information about the area of interest, such as population numbers and numbers of schools. 

Our last data layer includes situational information that is relevant to the humanitarian context at hand. The kinds of data relevant for this layer can vary significantly depending on the circumstances. This data is also likely to be the most dynamic and temporally sensitive. For example, it may be used to show change over time as a crisis evolves.

All of this data can come from a variety of sources. The Humanitarian Data Exchange (HDX), developed and maintained by the UN OCHA Centre for Humanitarian Data, is a repository that holds over 17,000 datasets from more than 1,300 different sources. These datasets come from what we might think of as ‘authoritative’ sources of information, such as the World Bank or the World Food Programme.

In particular, MapAction frequently uses the Common Operational Datasets of Administrative Boundaries (COD-AB) that are published and maintained by the UN Office for the Coordination of Humanitarian Affairs (OCHA). It can be challenging to access complete and up-to-date administrative boundary data, so the CODs attempt to provide standardised, high quality data that can be used to support humanitarian operations.

OpenStreetMap (OSM) also provides a valuable source of geospatial data. This ‘Wikipedia of maps’ is an entirely crowdsourced map of the world. In theory, anyone, anywhere in the world (with an internet connection) can contribute to OSM. At MapAction, we use OSM as a source of data for features such as settlements and transportation infrastructure. MapAction is a partner of the Missing Maps project, hosted by OSM which seeks to crowd source the gaps in maps in available maps.

So why can’t we just use maps that already exist, like Google Maps?, one might ask. Why all these complex data layers? Why spend so much time finding data when it’s already all there?

Platforms such as Google Maps, Waze, and Apple Maps are commonly used as day-to-day navigation tools for people in many parts of the world. However, such existing tools do not provide the flexibility that is often required when managing and presenting geospatial data in humanitarian scenarios. As these tools are privately-developed, individuals and organizations do not always have the ability to manipulate or style the underlying data to suit their needs. These platforms were not created specifically for humanitarian use-cases, and so may not always include the information that meets the operational requirements of humanitarian contexts, such as locations of damaged buildings or the extent of a flood.

OSM’s Humanitarian map style, for example, shows some of the unique data styling that may be required in humanitarian contexts. Moreover, there are many parts of the world with human settlements that are not present (or poorly represented) on existing maps, as is demonstrated by efforts from organizations such as the Humanitarian OpenStreetMap Team and the Missing Maps initiative. These challenges mean that there is no existing ‘one size fits all’ mapping platform that is capable of providing and presenting all of the information that is needed in humanitarian contexts. 

Finding high quality geospatial data is an ongoing challenge for us at MapAction. Geospatial data quality is a multifaceted concept, and includes dimensions such as up-to-dateness, positional accuracy, logical consistency, and completeness. The image below, for example, shows a geometry problem that we often face with administrative boundary data. Notice the gap in the border between Chad and the Central African Republic. Lack of standardisation in this data between different countries and organisations, or out of date data can result in such misalignment. Due to the political sensitivity that is associated with boundary data, it is important to ensure that the data that we use is as accurate as possible. 

Our ongoing work around the Moonshot project seeks to develop tools that can help us to automatically detect and address quality issues such as these. Keep an eye out for future blog posts where we will address some of these technical challenges in greater detail. 

At the end of the day, we’re working to make complex situations better understood. Humanitarian crises are incredibly complex, and accordingly, can be associated with complex datasets and information. By selecting high quality datasets and visualising them in clear and accessible ways, we intend for our humanitarian partners to be able to make informed decisions and deliver effective aid to those in need.

Ten tips for making simple, informative maps in a pandemic

MapAction has been collaborating for a number of years with French NGO and fellow humanitarian information management specialists CartONG.

In addition to our operational activities, we thought it would be worthwhile to pool our collective knowledge to create an informative article. The ten-minute read aims to give some helpful tips for people creating maps intended to assist humanitarian responses to the Corona virus and other pandemics.

Between us, we have a lot of experience of using geospatial analysis and visualisations to inform decision-making in this and previous epidemics, such as Ebola, as well as the current pandemic. We wanted to share this knowledge more widely and felt that, by working together, we could create something really useful and reach more people. Although it was written with pandemics in mind, many of the points apply to all kinds of map making.

MapAction’s Moonshot – origins and ambitions

History will always underscore how landing on the moon represented a significant milestone in the space race, yet what is often less spoken about is the number of technologies that might not have ever made it without space travel.

These include the all-important ability to take pictures on our phone, thanks to the technology originally created by a team at the Jet Propulsion Laboratory, and the technique used to develop diamond-hard coatings for aerospace systems that can now be found on scratch-resistant spectacles. Inventions that originally started life with a bigger purpose but have filtered down into solving some of the challenges in our everyday lives.

This brings us onto MapAction’s own Moonshot initiative – an ambitious programme of work encompassing step changes in the way we use different technologies in the course of our work. This includes things like how we triage, assign and manage the requests for support we receive, and how we can automate certain repeat activities. 

One of the first projects we are working on within the Moonshot programme will enable us to produce seven to nine key maps for 20 of the world’s most vulnerable countries automatically, using technology we’re developing that will provide benefits for many years to come. This is being funded through our partnership with the German Federal Foreign Office.

In the humanitarian sector, a perennial challenge is access to high-quality data. This need is even more acute in the chaotic aftermath of a humanitarian emergency, when data and maps are crucial to make rapid sense of the situation and plan the best response to save lives and minimise suffering. 

In the early hours of a crisis, one of the first tasks facing our team is to produce standardised ‘core’ maps that will be used throughout the response, regardless of the nature of the emergency. These provide contextual and reference information about, among other things, the local environment, population and infrastructure. Sometimes they are created under difficult on-the-ground conditions or with incomplete information. Once they are in place, they are used to create additional situation-specific maps by layering on top evolving information about the extent and impacts of the emergency and the humanitarian response.

As MapAction has made maps in hundreds of emergencies, it has become apparent that, in creating these foundational core maps, there are many repeatable, generalised tasks that could be handled much more quickly by a machine, achieving in seconds what used to take hours. This would give humanitarian decision-makers the orientation information they need immediately, and free up our specialist volunteers for actively assessing and engaging with the situation at hand and performing the mapping tasks that only humans can do. 

Moreover, by shifting the focus from reactive to proactive data sourcing and map production, we can ensure we provide the best maps possible – not just the best maps, given the time and data available and the prevailing circumstances in the midst of a humanitarian emergency. 

Many countries, particularly low and middle-income countries, are likely to have data gaps, and they are often also the countries that may have the least resilience to emergencies such as droughts or earthquakes. Identifying and addressing these data gaps in advance is a big part of the Moonshot project, and something that will have benefits for the humanitarian sector as a whole. 

Like the proverbial needle in the haystack, important data can exist within a subset of a much larger dataset and accessing it can be tricky. Finding a gap is even more difficult, as you’re looking for an unknown entity that isn’t there. The technology we’re developing for the Moonshot will help us to identify the hard-to-see data gaps and quality issues that currently exist. By discovering these, we can pinpoint what information will be needed to ensure a complete map and then work with partners around the world to proactively put in place missing data or improve what currently exists. 

The initial goal of the Moonshot is to publish 180 core maps (nine for each of the 20 vulnerable countries identified at the beginning of the project). The same processes will then be applied to other countries and, eventually, to other types of automated maps beyond these core ones. This means we will ultimately be in a position to expand our understanding and quality assessment processes for more data types. New opportunities and routes of travel are likely to emerge as the project develops.

The ambition is big, but the possibilities that will result from achieving this goal will fundamentally change the way we approach map creation in the humanitarian sector in the future.

In a series of blogs over the next few months, we will share the story of this work as it unfolds, as well as diving down deeper into specific elements of it.

Helping WHO with mapping in Libya and Chad

MapAction volunteers have been supporting the World Health Organization (WHO) in Libya and Chad to process and map data about health and sanitation services, in order to support the response to COVID-19.

The volunteers have been working remotely, alongside each country’s health cluster (networks of WHO partners that work together to relieve suffering and save lives in humanitarian emergencies). They have been helping to identify and map what healthcare, water and sanitation services and aid are being provided, by whom, when and where. This is known as 4W mapping and is important to help identify gaps and avoid duplication.

We are now looking at providing similar assistance to WHO in other parts of North and Central Africa.

COVID-19 government measures dashboard

We’ve helped ACAPS to put together a dashboard showing government measures being taken around the world. Data can be filtered by region, country, type of measure and timeframe.

We will be updating this twice a week. In the meantime ACAPS, MapAction and other organisations are looking at further topics to develop analysis for. 

Sharing insights at INSARAG meetings in Chile

This week, a MapAction volunteer has been participating in discussions and strengthening relationships with our partners at the International Search and Rescue Advisory Group (INSARAG) Information Management Working Group and Team Leaders meetings in Santiago, Chile. These conversations enable us to continuously improve how we visualise data collected by INSARAG teams.

Thanks to the USAID Office of U.S. Foreign Disaster Assistance for supporting our participation, as part of our joint programme to improve the ways in which geographical information systems (GIS), mapping and spatial analysis are used in humanitarian emergencies.
