Name

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

Synopsis

gshhgtograss -i gshhs_[f|h|i|l|c].b [ -xminx ] [-Xmaxx ] [ -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

-x: Specify a minimum (west) longitude.
-X: Specify a maximum (east) longitude.
-y: Specify a minimum (south) latitude.
-Y: Specify a maximum (north) latitude.

Examples

To convert the full GSHHS data set , try

gshhgtograss gshhs_f.b

Bugs

Not updated to handle the WDBII line data (borders or rivers).
