Adding support for EPSG:2065 and EPSG:5514

Open Kate-Lyndegaard opened this issue 2 years ago • 3 comments

Hi,

I would like to add support for EPSG:2065 and EPSG:5514 in deegree.

I manually created the deegree crs configuration files based on viewing existing configuration examples. I cannot find any documentation on how to create the files.

My datasets publish, however they are not displaying correctly.

Looking at the conversion parameters in the EPSG database, there are additional parameters however I don't know how to provide these in the deegree files.

Example - 5514 Conversion Parameters:

Can anyone tell me what is wrong?

Kind regards, Kate

There is some limited documentation in the XML schema located here: http://schemas.deegree.org/crs/3.4.0/crsdefinition.xsd

The answer on this question requires quite some research on the code of the CRS subsystem of deegree. Currently no committer is active and can answer this. You may consider to search for a similar CRS in the deegree configuration and try to adjust it to your needs.

@copierrj @tfr42 Thank you for responding, however based on the schema @copierrj shared, I cannot see how I can add the azimuth to the definition. AFAIK Krovak is an oblique version of the Lambert Conformal Conic projection with a pseudo standard parallel that intersects the centerline of the projection at a defined azimuth. I can try using the LambertConformalConicType instead of the TransverseMercatorType.
