Many users employ standard GIS client tools to combine environmental data (from ncWMS) with other data sources, either on the web or the desktop.
These clients are usually unable to access the extended capabilities of ncWMS beyond the standard WMS specification, but are still able to view metadata and generate map images. Unfortunately, many clients do not implement all aspects of even the standard WMS specification, hampering interoperability. For example, some clients do not understand Capabilities documents with nested Layers or do not support vertical or temporal dimensions.
