What is ESRI JSON?

[tmcw]

Could this link to ESRI JSON and possibly explain the difference between it and the common standard?

I'll dig up some references to the geoservices REST spec's JSON structure and add some documentation on how geoms are structured in those APIs. The idea is that we'd like to provide a nice way to pull in geojson (from everywhere...) and be able to at least map it in the Esri JSAPI

[tmcw]

The Esri (ESRI?) JSAPI doesn't support GeoJSON natively?

[chelm]

a topic of conversation for sure....

it'll be in there soon, until then we have this little bit of code to step around a few of the um...holes

Here are the links I found to describe ESRI JSON:

http://resources.arcgis.com/en/help/rest/apiref/feature.html
http://resources.arcgis.com/en/help/rest/apiref/geometry.html

I think the basic mapping from GeoJSON and ESRI JSON is:

Feature -> Feature
FeatureCollection -> (Array of Feature)
Point -> Point
MultiPoint -> Multipoint
LineString -> Polyline
MultiLineString -> Polyline
Polygon -> Polygon
MultiPolygon -> Polygon

Also, there's no direct mapping for GeoJSONs GeometryCollection! It's kind of like an array of ESRI Geometry objects...

I am working on updating the issue with GeoJson multi polygons. Thanks for letting me know about it.

For GeoJson Geometry Collections, I am converting them to feature collections using the first geometry type found in the GeoJson Geometry Collection. Maybe not the best solution, but since ESRI Fature Collections can only contain one geometry type, it’s the best I could think of.
