gshhgtograss - Extracting GSHHS and WDBII data in GRASS-compatible ASCII format
gshhgtograss -i gshhs_[f|h|i|l|c].b [ -xminx ] [-Xmaxx ] [ -yminy ] [ -Ymaxy ]
gshhgtograss reads the binary coastline (GSHHS) or binary river/border (WDBII) and and translates it into an ASCII format suitable for import into GRASS. It automatically handles byte-swabbing between different architectures. gshhs_[f|h|i|l|c].b One of the GSHHG binary data file as distributed with the GSHHG data supplement. Any of the 5 standard resolutions (full, high, intermediate, low, crude) can be used. The resulting files are called dig_[ascii|att|cats].gshhs_[f|h|i|l|c].
-x Specify a minimum (west) longitude. -X Specify a maximum (east) longitude. -y Specify a minimum (south) latitude. -Y Specify a maximum (north) latitude.
To convert the full GSHHS data set , try gshhgtograss gshhs_f.b
Not updated to handle the WDBII line data (borders or rivers).
