Andrew,<br><br>I believe your syntax is incorrect. Assuming that you are trying to exclude water from your image, it should be something like this:<br>% gdal_rasterize -b 1 -b 2 -b 3 -i -burn 0 -burn 0 -burn 0 -l gshhs_land gshhs_land.shp warped.tif<br>
<br>Have a look at <a href="http://www.gdal.org/gdal_rasterize.html">http://www.gdal.org/gdal_rasterize.html</a> for a list of all the options.<br><br>Roger<br>--<br><br><br><br><br><br><div class="gmail_quote">On Mon, Nov 10, 2008 at 11:11 AM, Andrew Brooks <span dir="ltr"><<a href="mailto:arb@sat.dundee.ac.uk">arb@sat.dundee.ac.uk</a>></span> wrote:<br>

<br>
I'm trying to overlay coastlines on an image using gdal_rasterize but<br>
can't get it to do anything at all.<br>
<br>
% gdal_rasterize gshhs_land.shp warped.tif<br>
Usage: gdal_rasterize [-b band] [-i]<br>
[-burn value] | [-a attribute_name] | [-3d]<br>
[-l layername]* [-where expression] [-sql select_statement]<br>
<src_datasource> <dst_filename><br>
<br>
The files are ok:<br>
<br>
% ogrinfo gshhs_land.shp<br>
INFO: Open of `gshhs_land.shp' using driver `ESRI Shapefile' successful.<br>
1: gshhs_land (Polygon)<br>
<br>
% gdalinfo warped.tif<br>
Driver: GTiff/GeoTIFF<br>
Size is 396, 396<br>
Coordinate System is: PROJCS["OSGB 1936 / British National Grid", ...<br>
Band 1 Block=396x10 Type=UInt16, ColorInterp=Gray<br>
<br>

<br>
P.S. Unrelated to this problem there's also another problem:<br>
<br>
% gdal_rasterize -l gshhs_land gshhs_land.shp warped.tif<br>
To many of -3d, -burn and -a specified.<br>
<br>
"To" should be "Too", but since I've not specified any of -3d,<br>
-burn or -a then I'm not sure what it's complaining about...<br>
