NAME¶

gshhgtograss - Extracting GSHHS and WDBII data in GRASS-compatible ASCII format

SYNOPSIS¶

gshhgtograss -i gshhs_[f|h|i|l|c].b [ -xminx ] [-X maxx ] [ -yminy ] [ -Ymaxy ]

DESCRIPTION¶

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].

OPTIONS¶
