Spatial Module Doc available in 2.2.x examples mixes lat/long

[Tore]

http://orientdb.com/docs/2.1/Spatial-Module.html  

The examples are mixing latitude and longitude.

Please check this: (it appears the restaurant is located in Ethiopia) This goes for all the examples. Please correct.

Thanks.

INSERT INTO  Restaurant SET name = 'Dar Poeta', location = {"@class": "OPoint","coordinates" : [12.4684635,41.8914114]}

Hi Tore

the docs is not incorrect.
The Spatial Module uses the spatial reference system EPSG 4326

http://spatialreference.org/ref/epsg/wgs-84/

and the x & y are projected in longitude (-180 +180) and latitude( -90 +90).

See here

http://geojson.org/geojson-spec.html#positions

and here

http://edndoc.esri.com/arcsde/9.1/general_topics/what_coord_sys.htm

Thanks
Enrico

Thanks Enrico
I used google coord and that worked. I wrongly assumed that was the system in question.
I will review the docs you provided.

Hello Enrico,

in your latest blog post(7/25) you state " ... coordinates (latitude, longitude) ".

It seems that this is the common understanding. All positions from Google

comes in this format(see attached png) and hence this was the way I understood it. 

In my view this will cause confusion as you can't expect every developer to

be a full fledged navigator. So why not say this explicitly - ODB does it the opposite way?

How come OrientDB selected EPSG:4326 ?

T.

Hi Tore

that was the legacy spatial indexing.  

EPSG:4326
Seems to be te standard widely used also in other GIS system.
