Hi Alexander,

  1. Conversion:GeoPackageto GeoPackage failed.

Unexpected error: Spatial reference system with EPSG code 100000 was not found. If this is a valid EPSG code, please, contact us via the free support forum at Aspose.GIS Product Family - Free Support Forum - aspose.com, so we can add support of this SRS.

Hi Dani,

Thank you for reporting the issue with the GeoPackage → GeoPackage conversion. I see the error:

Unexpected error: Spatial reference system with EPSG code 100000 was not found.

This means the GeoPackage contains a custom SRS that Aspose.GIS does not recognize out of the box.

Possible workaround:
If the custom EPSG 100000 is a user‑defined projection, you can define it manually before conversion:

var customSrs = new SpatialReferenceSystem(
    100000,
    "CUSTOM_SRS_NAME",
    "+proj=... +datum=... +units=... +no_defs"); // PROJ string for the SRS

SpatialReferenceSystem.Add(customSrs);

Then run the conversion again. This registers the missing SRS with Aspose.GIS.

Please share the requested details so we can reproduce the problem and provide a definitive fix.

Alexander, waiting to your answer.

Hi, @danies8
I reproduce this issue.

A “Spatial reference system with EPSG code 100000 was not found” error generally means that the software does not recognize this number in its local Coordinate Reference System (CRS) registry.EPSG codes are typically 4- to 5-digit numbers (currently ranging between 1024-32767 for standard codes, with newer ones expanding). A 6-digit code like 100000 is often a custom, temporary, or user-defined projection rather than an official EPSG standard.

Will it be fix in May?

What kind of fix are you expected ?
There is no spatial reference system with EPSG code 100000.
The number 100000 and above is the range that programs reserve for custom or temporary coordinate systems.
How do you get this file?

Hi Alexander,

Please use this link, I gave screenshot , which file is it ?
