Use of 0.75arcsec DEM mesh in FS2002?

I think also at one time Jim Keir built a little utility that would remove an entire LOD8 cell out of the default HP9 file. Then you would create your own LWM polys for the sea within the "knocked out" LOD8 cells.I actually use LWMViewer 1.3 to generate a source code listing of the default HP file, and manually delete any LWM polys or area fills in my project area, and then recompile it using the tmf macros and bglc that are also used in Ground2k4. I'm kind of concerned if sbuilder actually appends all the default data correctly or not. The problem is possible copyright issues with edited default files. UT-USA and Canada replace entire LOD5 HP files with their own data. If required Sbuilder can help, since you can append a neighboring default HP file and properly join your polys/shorelines to default data outside of your project area.scott s..
