Hi,
One closing "}" seems to be missing. There is EPSG:0"}}} but should be one
more. Otherwise validates in jsonling.com and in geojsonlint.com.
{
"type": "FeatureCollection",
"features": [
{ "type": "Feature", "properties" : null, "geometry":
{"type":"Polygon","coordinates":[[[207,483],[343,524],[298,386],[207,483]]],"crs":{"type":"name","properties":{"name":"EPSG:0"}}}
]
}
I was testing another part of GeoJSON (winding order of polygons) while I
noticed that the code that is run at geojsonlint.com has been changed so that
it is nagging about crs. I asked and Sean Gillies answered:
" The geojsonhint project is at https://github.com/mapbox/geojsonhint. Releases
before 2.0 (such as 1.2.1, from May 20016) will validate legacy GeoJSON."
