GIS / Spatial Data
CYPEX works directly on PostGIS: spatial columns keep their PostgreSQL
geometry or geography type, and applications read them through
generated queries and map elements. Generated default queries pass the raw
geometry through unchanged, which a browser cannot render — convert it
yourself with ST_AsGeoJSON in a custom query. Two Application Designer
elements consume the result: Leaflet Map GeoJSON displays it read-only,
and Leaflet Map GeoJSON Input adds drawing and editing of markers,
lines, rectangles, polygons, and text annotations. Both render over one
configurable base tile layer (OpenStreetMap by default).
