[sr.org] Discussion of open and authoritative projection databases

[manfred at egger-gis.at]

About ESRI:

In the last days i finished my work with Shapefile ProjectionFinder and published a free version for all worldwide registered EPSG - Codes in geotools 2.6.0 basing on local transformations.

During testing i saw that ArcGis 10.3.1 do not read WKT generated by geotools.org. I get a unknown projection message !

QGIS can read WKT by geotools without any problems. 

So i offer in my GUI two options (look at png) which WKT the user can generate (OGC or ESRI).

I think it would be important to offer in this maybe new projection database a ESRI WKT, too. In spatialreference.org there is a ESRI option.

Using ESRI as database was not my intention.

Best regards,

Manfred

http://lists.osgeo.org/mailman/listinfo/spatialreference.orgDear all,

Alright, we should start we these :
- spatialreference
- epsg.io
- projections/index.html
- https://github.com/ebrelsford/projestions#api
- http://www.epsg-registry.org/
- ESRI

Now we can seek for their projection databases format.

Spatialreference est écrit en python avec django (REST). I don't know about
the native format it uses, but we could ask Howard. I am not sure if it is
a SGBDR.

EPSG.io uses the epsg registry parsed into a sqlite database (about 36Mo),
unreadable.

projections/index.html is using Sphinx templating.

https://github.com/ebrelsford/projestions#api is EPSG <http://www.epsg.org/>'s
CRS data over a postgist table i think.

http://www.epsg-registry.org/ I don't really know. It seems to be private
code. Eventhough, we can download raw data from it in 5 different format.

ESRI. I don't know. Manfred ?

Regards,
Julien.
