Looking at the data - can I from the data in the database maximize the
amount of transformations I can do? As said I am only interested in
to/form WGS84, perhaps there is data hidden in that database that can
help gdal, help me set up gdal, to do the transformation required. The
data I have no
Ah, ok.
Hard to find all details by yourself. :)
Finds in the database, for example, that area 2847 is valid between Lat
56 S, Lat 68 N, Lon 14 W and Lon 17 E approximately.
Just need to get it to a format my program like, XML will do fine and
Excel should be able to do it.
Thanks

Yeah, I mean the "area of use" as EPSG call it. You can download the
EPSG database which contains a table with areas of use from
http://www.epsg.org/Geodetic.html and extract that for use in your
application if that is going to be helpful for you.

You mean
area_of_use_code="2847"
which gives
area_of_use="Sweden. For medium and small scale applications:- all
country. For large scale applications:- communes between approximately
14 deg 40 min and 16 deg 55 min East. See information source for map."

I think the EPSG dictionary defines areas of validity for the defined
coordinate systems. That could be a starting point, although there
may be a better solution

No one?
Ok, I guess then that there are no common function/method of doing this.
My approach will the be trial and error. From WGS 84 transform to the
local coordinate system and back again to WGS84 and check if the result
seems valid.
Should work or any expert here have another solution?
