I've been working through the Water Data tutorial (thanks for that) to generate water topos in one area of Wisconsin and everything has gone fairly smoothly until I try to export the Shapefiles from postgis. Using the DOS command suggested I get a WARNING: Cannot determine spatial reference (empty table or unknown spatial ref) No prj file will be generated.
It must have problems with the database. I did not get any indication of problems before this point.
If anyone has any ideas I'd appreciate it.
Thanks
Not getting a .prj file isn't the end of the world. When you bring it into the next program just know what the datum is. In many cases its WGS 84 or a specific UTM zone. It should be in the metadata for whereever you got the water data from.
If you're following the tutorial exactly you should have a .prj file already for the water data.
