- In Arc 6.1 Arcplot, I am using SURFACEDRAPE POLYS <covername> to drape filled
- polygons representing land-use areas over a terrain model. The surface, derived
- from USGS DEM data, is a LATTICE generated by DEMLATTICE. Projection of both
- the coverage and the surface is geographic (lat/lon).
-
- Problem: The fills in the draped polygons are spreading so that they slightly
- overlap the fills at the edges of neighboring polygons. Yet polygon topology
- checks out normal. What's going on?
-
- Thanks for any help. -LJ
