Dear List I have a habitat layer (MAP PLOT) and another layer of many polygons - Sites of Special Scientific Interest. The habitat layer is continuous but I am only interested in the habitat area under the SSSIs (for this query). It seems I can only investigate change using the centroid Map Plot (hectare squares with attribute data) and so I can not use a proper digitised habitat dataset for this query.
There appear to be many ways to do this but has anyone got a quick and accurate solution? I have been looking at the Cookie Cutter (wouldn't do it - in a relatively short time - maybe it can't be used to cut multiple polygons?); Querying (presently trying out one using "Intersect obj" which is taking ages but may work); Buffering? Thematic maps? Deleting outside object and so on ... Any ideas gratefully received. Cheers Jacqui Middleton
