What Is GIS?
“a system designed to capture, store, manipulate, analyze, manage, and
present all types of geographically referenced data. In the simplest terms,
GIS is the merging of cartography, statistical analysis, and database
technology.”
– Wikipedia, 2011
GIS = Geographic Information System

Why is GIS Relevant?

Why GIS? A Platform for Humanitarian Assistance
Capabilities and templates for:
– Dashboard / Situational Awareness
– Mobile Data Collection / Field Support
– Briefings
– Planning
– Spatial Analysis
– Crowdsourcing
– Social Media Integration
– Paper Map Production
– Public Information
– Advocacy

Why GIS? Power of Spatial Analysis
Spatial analysis is the process of identifying
meaningful patterns in spatial data and
drawing conclusions from them.
![Page 9: Enabling Data-Driven Decision Making Using GISsolutionscenter.nethope.org/assets/collaterals/enabling_datadriven... · Enabling Data-Driven Decision Making Using GIS Steve Hellen](https://reader036.vdocuments.site/reader036/viewer/2022062506/5f0cdab87e708231d4377617/html5/thumbnails/9.jpg)

• Queries
– How many people live within 100 meters of a river’s floodplain?
– What percentage of people located above an elevation of 3000 meters have not received winterized
tents?
– Are refugee camp operations compliant with UNHCR or Sphere guidelines for providing water and
sanitation?
• Transformations
– Where is the best location for a health clinic if it needs to be within 10 km of surrounding villages, within
50 meters of a main road and more than 500 meters from areas known to contain land mines?
– Which villages need to receive additional services given their distance from roads, humanitarian hubs
and a natural disaster?

• Optimizations
– What is the most efficient route between our office and each of our field sites?
– What would be the best location for a maternity clinic if it needs to be within a 20-minute drive from
surrounding villages?
• Geostatistics
– What is the best village in which to rent an office based on market rates and the weighted distribution of
surrounding populations?
– Is there a relationship between a rise in cholera infection and the available sources of drinking water?
• Hypothesis Testing and Simulation
– What will happen if the river flood level rises 2 meters in the next week?
– What percentage of local buildings will be seriously damaged or destroyed after an earthquake
measuring 7 on the Richter scale?
– What will happen if a glacier lake outburst flood occurs in this valley?

What is the Value? Forming a Business Case
Alignment to agency strategy
Meets field requests
Benefits that reach multiple
stakeholders

What is the Value? Meeting Needs of Field Projects
• Staff in 12 countries requested GIS assistance
• CRS’ ArcGIS Online environment has 77 publishers
• 43 members in CRS’ informal GIS community
During the first quarter of 2015:

What are the benefits to an international NGO?
Decisive Influence on Program Delivery
• Site selection
• Vulnerability estimation
• Cluster analysis
• Network optimization
Impactful Advocacy
• Maps as powerful communication tool
• Emergency response
• Charitable giving
Uncover Data
• Visualize data from existing systems
• Share data using open data platform
![Page 19: Enabling Data-Driven Decision Making Using GISsolutionscenter.nethope.org/assets/collaterals/enabling_datadriven... · Enabling Data-Driven Decision Making Using GIS Steve Hellen](https://reader036.vdocuments.site/reader036/viewer/2022062506/5f0cdab87e708231d4377617/html5/thumbnails/19.jpg)

What is the Value? Maps to
Communicate
The maps you created make this report come
to life. It is difficult to tell a story when the
place is out of reach for most people. Your
maps help tell the story of the people who
have been suffering for years under the
constant threat of violence and lack of basic
commodities as a result.
We are already helping these people with the
resources we have and I am confident that
this assessment will help increase the
assistance to the right people, whether that
be through CRS or other organizations.
