SWEREF 99 TM or User Grid

[GPSuser]

Hi,



I used OruxMaps with Swedish Maps.



However, I did not manage to display either Swedish Grid Coordinates (SWEREF 99 TM) or approximate them with a "user grid".



It seems a good match can be obtained with the WGS-84 based "user grid" that some GPS devices offer:

This page states:



Some new GPS receivers have SWEREF 99 TM installed, but otherwise you can often create the Transverse Mercator projection that is needed to present the positions in SWEREF 99 TM. The difference between SWEREF 99 and WGS 84 is (at present) negligible in this context.



Map datum must be set to WGS 84. The parameter values to be used with the User grid are shown in the table below.

Parameter    Value

Central meridian    15°E Greenwich

Scale reduction factor    0.9996

False northing    0 m

False easting    500 000 m



Is such a setting possible in OruxMaps? I did not find "user grid" settings. These would be very useful, also for other countries since it would allow at least an approximation of the local coordinate grid.
