wkb to GeoJSON #5

Closed spatialhast closed 9 years ago

spatialhast commented 9 years ago

I store coordinates in wkb format (data get from PostGIS DB, geometry Field the_geom geometry(Geometry,4326)). Example http://spatialhast.github.io/index.wkb.to.geojson.html. In ' var the_geom' - wkb data of polygonal geometry. In geometryType of wkx.js I receive wrong number of geometry type (536870915). In 'var geojson' - example of GeoJSON data which need receive wrom wkb data. Possible convert wkb in GeoJSON data (to display on map via Leaflet.js)?

PostGIS stores the geometry in ewkb format. You can use ST_AsBinary to get wkb out of it.

Thanks! Initially I use https://github.com/tobinbradley/dirt-simple-postgis-http-api to publish data from PostGIS DB in JSON format and there data in geometry field is in WKB format. Using wkx plugin I want convert in GeoJSON format. I change SQL query in from dirt-simple-postgis-http-api plugin to receive GeoJSON format.

@cschwarz is a conversion from EWKB something you've attempted? Or is it not possible?
