Re: [udig-devel] How to add a coverage layer in code?
|
The concept of "temporary resource" has its own extension-point; looks like you can add a placeholder for an in memory grid coverage; right now I just see a single implementation for turning a FeatureType into a temporary MemoryDataStore.
What would a good descriptor be in this case? Probably a GridCoverage2D (I think that is the in memory implementation of grid coverage is it not).
Cheers,
Jody

I assume you could have a look at the geotiff service implementation.
In the GeoTiffServiceExtension class the service is created.

private URL extractID( Map<String, Serializable> params ) {
URL id;
if (params.containsKey(URL_PARAM)) {
Object param = params.get(URL_PARAM);
...
it looks to me that the url should be enough.
Humpf, now I see your point, you have an in memory thing? Is that the
real problem?
