[...] .NET-bibliotek med möjlighet att konvertera mellan dessa format. Björn Sållarp har snickrat ihop MightyLittleGeodesy. Eftersom det är ett vanligt .NET-bibliotek var jag tvungen att ladda ner källkoden och bygga [...]

Hej Johan

Arnold Andreasson has no copyright for the calculations. The algorithm used is Gauß-Krüger projection. Formulas are published here:

So as far as you have not copied the code from Arnold you can use whichever license you want for your work.

Johan,

If it was up to me I would distribute this without a licence. Because the calculations are based on the work by Arnold Andreasson I want to respect his licence. Contact Arnold Andreasson (http://latlong.mellifica.se/) and ask him to change his licence, that way I can change mine.

Hey Mathias,

Great job! If you haven’t yet, update wikipedia with a link to your library for RT90 etc. I put my url there and lots of people find it that way.

Hi. Thanks for an excellent library, it helped me a lot.
Because I couldn’t use it as it was (c#) i needed to port it to java instead.
If you or anyone else need the java version you can find it on:

Hope it is ok that I release my java version of your library.

Thanks for your feedback Otto,

I’ve updated both the compiled binary and the source. Good luck with your project!

Och så var det en till liten bugg.

Denna gång i RT90Position.cs, rad 132, metoden ToString().

Ut:
return string.Format(“X: {1} Y: {2} Projection: {3}”, Latitude, Longitude, ProjectionString);

In:
return string.Format(“X: {0} Y: {1} Projection: {2}”, Latitude, Longitude, ProjectionString);
