@RyanWhitley To convert polygons to polylines in GRASS:
v.in.ogr dsn=<input>.shp out=chad
v.build.polylines in=chad out=chad2
v.out.ogr type=boundary in=chad2 dsn=grass_chad_lines.shp

@RyanWhitley Here's how you can do it to lines:
v.in.ogr dsn=AdminLine2.shp out=chad
v.clean tool=rmdupl in=chad out=chad2 <--new step to remove dupe segments
v.build.polylines in=chad2 out=chad3

Converting DEM (or other raster format) to RAW for import into Unity
View gist:350c21e54ac8d8129fae
gdal_translate -ot UInt16 -scale -of ENVI -outsize 1025 1025 Seattle_16Int.tif seattle_heightmap.raw
-of ENVI means it will write out RAW
This works fine. However, importing this .raw file into Unity produces an Vertically inverted terrain.
I opened with Photoshop CS, then did Image > Flip Vertical.
“Save As” Photoshop RAW. Options were blank, but saving worked.
Loaded into Unity as a terrain setting. Then manually set the Terrain height to 75, which when walking around seems right.
