# gshhgtograss(1gmt)

Extracting GSHHS and WDBII data in GRASS-compatible ASCII format

## NAME

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

## SYNOPSIS

**gshhgtograss** **-i** gshhs\_\[f\|h\|i\|l\|c\].b \[ **-x***minx* \] \[**-X***maxx* \]  \[ **-y***miny* \] \[ **-Y***maxy* \]

## 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).
