Re: [udig-devel] How to add a coverage layer in code?

Hi Graham,
were you able to solve this?

I assume you could have a look at the geotiff service implementation.
In the GeoTiffServiceExtension class the service is created.
>From a quick (very quick) look at extractId:
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?
