I have written a Delphi library for reading shapefiles. Now I'd like to test it with some real data, but cannot find any shapefiles containing the "M" variety of data:
- PointM, MultiPointM, PolygonM or PolylineM
- and also "Z" data (PointZ, MultiPointZ, PolygonZ or PolylineZ) including the optional "M" data.
Any hints where I can get some test data of this kind?
https://gis.utah.gov/data/sgid-transportation/roads-system/ apparently links to some files but the ftp server times out on me.
