[PostNAS] ogr2ogr defaults

[Lars O. Grobe]

Hi Frank, hi others,

sorry for posting my initial question in German. The archive is mixed, and I assumed the whole NAS-topic to be rather Germany-specific. However this is also part of a global GIS-community... Thank you for your very helpful reply!

For my data, ogr2ogr does not find any information on the coordinate system, so as far as I got it for now, it just writes unchanged data in a new format.

What I found irritating is that my umt coordinates lead to measured distances which would have to be scaled up to match true distances/surface areas, as far as I understood. My CAD does not know about this, so dimensions get wrong. Are there others here interfacing GIS and CAD? How do you handle this? Do you set a multiplier in your dimensions, do you scale your drawing? Or did I get the whole true-area / true-length issue entirely wrong?

Cheers, Lars.
