Global Mapper v25.0

Incorrect Reading of Geojson Header Information

tfitz2001 Global Mapper UserTrusted User
I have some geojson files that are not being projected correctly in GM 19.1. It appears that GM is not reading the header information correctly. When loaded, the projection is designated as Mercator projection at WGS84, though the EPSG code in the header file is listed as 3857. The projection in the header when imported into notepad is as follows:

"crs": { "type": "name", "properties": { "name": "urn:ogc:def:crs:EPSG::3857" } }

Would like to get this corrected, so I do not have to manually adjust the projections each time.
