Old school D3 from simpler times
Shaded Relief Map
Shaded relief map of Wisconsin.
The recipe for creating the shaded relief raster image came largely from
Thomas Thoren's great blog post
Making a New York Times Map.
Derek Watkin's GDAL cheat sheet
and SRTM Tile Grabber were also very useful.
This recipe is in the two bash scripts in this gist repo.
make-borders.sh creates the Wisconsin state and county borders
vector data. Second,
make-shaded-relief.sh creates the shaded relief
raster data from NASA's STRM data.
The scripts need to be run in that order. The borders data is used to
clip the raster data.
