Dear Ondrej,

I have a regular error with GetWTK and GetUTM components, the error message is:
1. Solution exception:hostname ‘spatialreference.org’ doesn’t match ‘bottle.download.osgeo.org’
I attached the screen to this message.

Best,
Artem

Dear Artem,
thanks for reporting this.
Seems that spatialreference.org admins recently made some changes to their server, which now requires additonal certification, ooof.
I will try to fix the WKT components asap.

In the meantime, you can still get the WKT strings for each spatial referance system manually at https://spatialreference.org/ref/.
Just find the CRS you need and open the ESRI WKT definiton (as ie. here) and use them in the same way as you would use the WKT components output.

Best, Ondrej

Dear Ondrej,

How to know which projection is suitable? For Germany there are several systems(I just searched Germany on the website):
SR-ORG:6912: EPSG:31493
SR-ORG:7268: foo
SR-ORG:7317: LAMGw
SR-ORG:7325: ETRS89 Zone32 Germany
SR-ORG:7411: LAMBERT WGS84, GERMANY
SR-ORG:7519: DHDN / 3-degree Gauss-Kruger zone 6
SR-ORG:7520: DHDN / 3-degree Gauss-Kruger zone 6
SR-ORG:8614: Eastern Germany
SR-ORG:8615: Eastern Germany

how to use the text that is generated in ESRI WKT definition, just put it in the panel?

Well, any projection system that projects local map features into true scale with real proportions should be fine.
However, I would recommend to work within the UTM system. It’s a global set of projections, reasonably accurate in all areas (except when close to poles, ie. northern parts of Scandinavia). Then you don’t have to worry about reasearching local projections systems, which are in most of the cases created by national geographic agencies and are specific to each country.

All the WKT components do is try to get the correct WKT string from spatial-reference.org, so if you’ve found your WKT, just put it in a panel and use it instead of the WKT components.

I’m sorry for the complications.

[Ondřej Veselý]

Ok, I fixed the issue with WKT components, which now skip the server certificate validation when accessing spatial-reference.or and therefore shouldn’t cause any problems no more.

Please replace the Geospatial.p2.7.5.0.gphy in your DecodingSpaces Libraries with the file from attached archive (don’t forget to UNBLOCK) and try again.

Best, Ondrej
