Swedish reference system outdated?

The "Swedish Grid" projection seems to be strange. The geotiff key gives 30800 which is the deprecated RT38 2.5 gon W. I'm told that the real code for RT90 is supposed to be 2400 (or better yet 3021, which succeeds 2400).
Also, Sweden are in the process of using a new reference system (SWEREF99). Will there be support for this in future versions of GlobalMapper?

    Thanks for pointing that out. I have added support for using EPSG codes 2400 and 3021 (with 3021 now being the default) for the Swedish Grid projection. I have placed a new build at http://www.globalmapper.com/global_mapper10.zip with the change for you to try. Simply download that file and extract the contents into your existing v10.xx installation folder to give it a try.

    Let me know if I can be of further assistance.
