Autocad tinker12/27/2023 The point of this blog is not to point out a particular software issue, but to show you how you might change that georeferencing to something that works. I don’t know for sure that this is the problem and I’ve only gotten reports for Mississippi and Massachusetts using survey feet, so it could be a very isolated problem. I don’t have a license for AutoCAD, so debugging is difficult, but a bit of back and forth with our users is suggesting that AutoCAD Civil3D isn’t liking files tagged with State Plane NAD83(NSRS2007) but does fine with the same files tagged with NAD83(2011). Recently I’ve been hearing from AutoCAD users that our data isn’t landing in the right place. Those examples are why the Data Access Viewer will georeference with NAD83(NSRS2007) tags instead of NAD83(2011) tags. I showed a couple of examples from ArcGIS. I’m leaving the post up as I think there are still some useful things in it.Ī few months ago I wrote about georeferencing and noted that sometimes your software doesn’t read it right. I’ve set our system up to use the old key specification with a -co GEOTIFF_VERSION=1.0 argument, so they should get data they can read again. AutoCAD, at least the versions some people were using, didn’t fully understand that specification and got a few things wrong. We upgraded to GDAL version 3.2 a few months ago and it defaults to the newer OGC specification for GeoTIFF keys (version 1.1). Update, March 2, 2021: I believe I’ve figure out what was happening with our GeoTIFFs and AutoCAD.
