Can someone please explain why these two shapefiles are different:

  1. Neighborhoods in Cambridge, MA ; and
  2. Water bodies in Cambridge, MA.

In particular, I am having trouble working with the water bodies shapefile. The program I am using (Stata) gives the following error message when I try to work with the water shapefile: "point, polyine, or polygon shapefile required." However, the neighborhood shapefile works just fine.

  • Hi, the link to the water bodies shapefile is incorrect.

The Neighborhoods are plain old Polygons. The Water is Polygons with ZM Values.

This is likely your fix. Remove the Z and M values and I suspect Stata will read it.
