This is a concept project created to demonstrate YARWELL's approach. It does not describe a client engagement, and the interface shows illustrative data only.
Project details
Development programs collect large volumes of field data that often sit in spreadsheets without location context, making it difficult to see which communities are reached and where gaps remain.
Survey submissions are geotagged at collection and stored in a spatial database. A web map layers program data over administrative boundaries, while spatial queries compute coverage, clusters and distance to the nearest service point.
