GeoJSON Attribute & Spatial Join

Local

Join two GeoJSON layers in your browser: attribute join by matching keys, or spatial join merging polygon attributes into contained points.

Attribute join merges properties by matching keys; spatial join merges properties of the polygon containing each target point.

What is it? GeoJSON Attribute & Spatial Join joins two layers either by matching attribute keys or spatially (for example merging polygon attributes into the points they contain).

TL;DR: Attribute or spatial join two GeoJSON layers.

How to use

  1. Load the left and right layers.
  2. Choose attribute or spatial join and the matching key.
  3. Download the joined result.
