This how I do it and it works for esri asc and should also for tiffs
(I had to remove some code, but I think it should compile and work):
private void loadFileInMap( File file ) throws Exception {
URL fileUrl = file.toURI().toURL();
CatalogPlugin cp = CatalogPlugin.getDefault();
IServiceFactory sf = cp.getServiceFactory();
List<IService> services = sf.createService(fileUrl);
List<IGeoResource> resources = new ArrayList<IGeoResource>();
for( IService service : services ) {
List< ? extends IGeoResource> geoResource =
service.resources(new NullProgressMonitor());
if (geoResource != null) {
for( IGeoResource iGeoResource : geoResource ) {
resources.add(iGeoResource);
}
}
}
if (resources.size() == 0) {
return;
}
IMap map = ApplicationGIS.getActiveMap();
LayerFactory layerFactory = map.getLayerFactory();
for( IGeoResource resource : resources ) {
Layer layer = layerFactory.createLayer(resource);
AddLayerCommand cmd = new AddLayerCommand(layer);
map.sendCommandASync(cmd);
}
}
