Uploading a layer

You upload a layer once, and it stays available as an overlay for everyone in your organization.

  1. On the Map layers page, find Upload a boundary layer.
  2. Enter a Name that will read clearly in the layer list, for example “Watersheds 2024”.
  3. Choose a File: a shapefile as a .zip, or a .geojson (or .json) file. The limit is 12 MB.
  4. Choose Upload. The layer appears in the Layers list with its feature count, geometry type, file size, and the date you added it.
  • Shapefile. Upload it as a single .zip that contains its parts, at minimum the .shp, .dbf, and .prj. The .prj matters: it tells CensusIO the coordinate system, so the boundary lands in the right place. Your browser reads the zip and converts it before uploading.
  • GeoJSON. A single .geojson or .json file holding a feature collection, a feature, or a bare geometry.

In the Layers list, choose Remove on the layer and confirm. Removing it takes the overlay off your maps. It does not affect any survey records.
