5 | | The above cmd line creates a set of PostGIS tables, but some of the tables' wkb_geometry fields are empty - for example NHDARea, HYDRO_NET_Junctions. |
6 | | The NHD shape fields appear to have type 19 for polygons and type 9 for points which are unknown types, to me. The shape object signatures appear to match PolygonM, 25, and PointM, 21, but since the types do not match measure features the Mmin, Mmax, Marray may mean something different. |
