Hi Jason Do we actually support anything other than MultiPolygons and Points? For my GeoJson exporter, I default to MultiPolygon unless its a Point.
I have been able to successfully render all geojson using http://geojson.io What is supported by GIS, I don't know, Jan would have to explain that. -- Morten On Tue, Jan 5, 2016 at 7:16 PM, Jason Pickering <[email protected] > wrote: > > Hi Devs, > I am attempting to directly update the coordinates using the WebAPI, but > am running into issues with the formatting (I think) of JSON fragments. > > The worflow is as follows. > 1) Use MapShaper to simplify the coordinates. > 2) Export as GeoJSON. > 3) Use curl to PUT the coordinates to the correct end point, e.g. > http://myserver/api/organisationUnits/abcd1234/coordinates > 4) Use curl to PUT the feature type (either "POLYGON" or "MULTI_POLYGON") > depending on what is reported by the GeoJSON. > > That part seems to work fine and I get something which looks like this. > > > Sample polygon.. > > { > > - featureType: "POLYGON", > - coordinates: > "[[[[125.8054,-8.7452],[125.8038,-8.7455],[125.8031,-8.7455],[125.8031,-8.7471],[125.8028,-8.748],[125.8021,-8.7488],[125.8013,-8.7492],[125.8004,-8.7494], > > > Sample MultiPolygon: > > > { > > - featureType: "MULTI_POLYGON", > - coordinates: > "[[[[[127.3286,-8.448],[127.3281,-8.4479],[127.3272,-8.4476],[127.3271,-8.4473],[127.3267,-8.447],[127.3254,-8.4473],[127.3251,-8.4471],[127.3249,-8.4466],[127.3246,-8.4465]... > > > > In the GIS client, when loading any of the MultiPolygon's I get > Uncaught TypeError: Cannot read property 'length' of null with > util.map.getTransformedFeatureArray. > > If I mangle the GeoJSON such that is has four square brackets (instead of > five as above) things works OK.
