Re: [udig-devel] add GeoTifff Image

Only one small detail; making a URL from a File is super scary (when you get into things like windows network shares and so on). There is a DataUtilities method to do the conversion for you...

You can manually create your service and add it to the catalog like so.

 

IServiceFactory serviceFactory = CatalogPlugin.getDefault().getServiceFactory();
IService service = serviceFactory.createService(new URL("file://"+path));

 

try {
    IServiceInfo info = service.getInfo( null );  // try connecting to make sure the service works

 

    if (info != null) {
         CatalogPlugin.getDefault().getLocalCatalog().add( service ); // add service
    } 
}catch (IOException couldNotConnect ){
     service.dispose(new NullProgressMonitor());
}

 

However the catalog provides the acquire method that will do all the work for you.

 

IService service = CatalogPlugin.getDefault().getLocalCatalog().acquire(new URL("file://"+path), new NullProgressMonitor());

 

Simply call this from your menu contribution and provide the path to your GeoTiff.

 

One thing to note is that the acquire method douse not guarantee that a geotiff service will be used to render your layer. If it I important that your layer use a geotiff render you will have to use the manual service creation method.

Subject: [udig-devel] add GeoTifff Image

Hi,
I wuold like to add a geoTiff image on a 2D map simply pressing a button.

The functionality is the same as "right click on a map" -> "add files" -> "and select a GeoTiff image"
but I don't know which classes I should use and in which way.

Thanks.
Alberto
