Flowcharts for Geospatial Analysis Decisions

by on July 28, 2014

The flowcharts below represent the sequence of decisions that need to be made as part of the geospatial analysis. The first flowchart focuses on how to decide whether to make a choropleth map or a catchment area analysis based on the nature of the geographic identifier in your data. The second flowchart gives guidance on deciding what kind of catchment area analysis you can carry out with the data that you have.

The flowcharts and more can be found in Using Geospatial Analysis to Inform Decision Making in Targeting Health Facility-Based Programs: A Guidance Document.
