NAME
gshhs - Extract ASCII listings from binary GSHHS or WDBII data filesSYNOPSIS
gshhs binaryfile.b [ -L ] > asciifile.txtDESCRIPTION
gshhs reads the binary coastline (GSHHS) or political boundary or river (WDBII) files and extracts an ASCII listing. It automatically handles byte-swabbing between different architectures. Optionally, only segment header info can be displayed- binaryfile.b
- GSHHS or WDBII binary data file as distributed with the GSHHS data supplement. Any of the 5 standard resolutions (full, high, intermediate, low, crude) can be used.
- -L
- Only outlut a listing of polygon or line segment headers [default outputs headers and data records].
EXAMPLES
To convert the entire intermediate GSHHS binary data to ASCII, run
gshhs gshhs_i.b > gshhs_i.txt
To only get a listing of the headers for the river data set at full resolution, try
gshhs wdb_rivers_f.b -L > riverlisting.txt
BUGS
While the GSHHS data is organized as a set of closed polygons, the rivers and boundary data are just a set of line segments in no particular order. Thus, it is not possible to extract information pertaining to just one river or one country.SEE ALSO
