Aihe: Re: [Geoserver-users] [Geotools-gt2-users] gdal Java bindings
Hello,
I am currently working on a project that has similar needs to what you
stated. I'm using Java for a GeoTIFF pull, and need to reproject as well as
place the file in the proper Geoserver folder (data/coverages). A full jgdal
would be nice, but until then I'm using the work-around of calling the
process from inside Java. Sample code is below:
private static void reprojectTIFF() throws IOException {
String s =
"../webapps/geoserver/data/coverages/FWTools-1.3.9/bin_safe/gdalwarp -t_srs
\"+proj=latlong +datum=WGS84\" ../webapps/geoserver/data/coverages/input.tif
../webapps/geoserver/data/coverages/output.tif";
Runtime rt = Runtime.getRuntime();
Process p = rt.exec(s);
}
Use the following code to reload the catalog:
http://docs.codehaus.org/display/GEOSDOC/Alternative+for+reloading+the+Geoserver+catalog
Hopefully this is close to what you were looking for.
