We use an ancient Macon MapKit! component to display GIS maps in a Windows gui.

Does anyone know what has become of MapKit! ? All traces of MapKit! have been removed from the current GfK GeoMarketing (their new name) web site.

And more specifically, is there any way to convert the maps (extension .mkl and .mkb) from/to other GIS formats?

Well, you can definitely use the ActiveX component to read out the table data, as per this sample program (in German but I'm sure you'll find the code understandable enough). I'm not sure whether you can access the geometry data, however. Hopefully this is sufficient for you.

Otherwise, you might like to try what seems like the successor to the MapKit product, RegioGraph. RegioGraph claims to be able to read .mkl and .mkb files, but I'm not sure whether it will allow you to export them as anything other than their new proprietary format, .gfk.

If you speak German or can track down someone who does, I suspect you'll get better answers from the RegioGraph support forum. It seems quiet, though not abandoned.

Good luck, and be sure to write an answer here if you find a solution to your problem.
