Geometry Fields plugin for Strapi

Store and edit geospatial data with PostGIS in a Strapi v4 custom field.

NOTE: For this plugin supported by Strapi v5, see @gismark/strapi-geometry-fields.

The plugin accepts WKT (Well-known text) from the API and stores it in a PostGIS column in the db table of the content type. You can use multiple geometry fields across different content types. All features are editable and draggable using the hosted Leaflet.Editable and Path.Drag.

Below is an example following this WKT input: "GEOMETRYCOLLECTION (POINT (40 10), LINESTRING (10 10, 20 20, 10 40), POLYGON ((40 40, 20 45, 45 30, 40 40)))"
