Coverage representations, as defined by the OGC specifications, are useful for representing a wide range of geographic phenomena. However, in most GIS projects, coverage representations do not show a common interface and the line between coverages and features with geometry is unclear. We propose an extension to the TerraLib library, using a unifying approach to manage coverage representations, including performance considerations as a major issue.
