Count points in each area — free

How many customers are in each region, or how many trees are in each park? Drop your areas in box 1 and your points in box 2. DropMaps adds a column to each area with how many points fall inside it.

      How to do it

      1. Any map file works: a zipped shapefile, KML or KMZ, GeoJSON, GeoPackage, GPX, a CSV with coordinates or a zipped .gdb.
      2. Drop the areas into box 1 and the points to count into box 2. You can also drop both at once, then use “Swap” if they landed the wrong way round.
      3. Click “Set up Count”. DropMaps opens in a new tab with your data on the map and the Count points in polygons tool open, your layers already picked.
      4. Leave the spatial relationship as it is, and change the name of the new count column if you like. Then click Run.
      5. The result appears on the map as a new layer. Click “Save result…” to download it as a shapefile, KML, GeoJSON, GeoPackage or CSV.

      Questions

      Can my points be in a spreadsheet?

      Yes. Save it as a CSV with latitude and longitude columns and drop it in box 2.

      Can I colour the areas by the count?

      Yes. Once the result is on the map, open its style settings and colour it by the new count column.

      What if both layers are in one file?

      Drop the file into box 1 only. Once DropMaps opens, pick the second layer from the list in the tool.

      How do I get the result?

      The result appears on the map as a new layer. Click “Save result…” under the Run button and choose a shapefile, KML, GeoJSON, GeoPackage or CSV.

      Is my data uploaded anywhere?

      No. The tool runs inside your browser, on your own computer. Nothing is sent to us unless you choose to save the map to a DropMaps account.
