Hello,
I continue to have this problem.
When I lunch a command, for example:
grass r.slope.aspect.exe elevation=inputMap slope=outputMap prec=float
zfactor=1.0
without problem. Then I add to map from database JGrass outputMap.
The outputMap isn't visible and there is this comment:
"Sistema di coordinate di dati sconosciuto. Se non viene definito si
può avere un comportamento inaspettato dell'applicazione."
My os is Windows xp. I tested with the today latest JGrass src and
also with jgrass-1.1.x-build20081112015624-win32.win32.x86.zip.
I solve programmatically with the code to add a layer to current map:
public void addResourceFromLocation(String locationPath, String mapsetName,
String mapName, IProgressMonitor progressMonitor)
throws MalformedURLException,
UnsupportedEncodingException {
if (JGrassPlugin.getDefault() != null) {
// refresh the location
JGrassCatalogUtilities.refreshJGrassService(locationPath,
progressMonitor);
File locationFile = new File(locationPath);
IMap activeMap = ApplicationGIS.getActiveMap();
URL mapurl = null;
String locationFileURIURL =
locationFile.toURI().toURL().toString();
if (locationFileURIURL.lastIndexOf(ConstantUtil.slash)
== (locationFileURIURL
.length() - 1)) {
locationFileURIURL =
locationFileURIURL.substring(0,
locationFileURIURL.length() -
1);
}
mapurl = new URL(locationFileURIURL +
ConstantUtil.numberSign
+ ConstantUtil.slash + mapsetName +
ConstantUtil.slash
+ JGrassConstans.CELL +
ConstantUtil.slash + mapName);
Activator.log("mapurl to add current map: " +
mapurl.toString(),
null);
JGrassCatalogUtilities.addResourceFromUrlToMap(mapurl,
progressMonitor, -1, activeMap);
}
}
Some idea?
Thank you,
Giuseppe
