rView is a visual frontend to the RasDaMan DBMS, providing raster data visualization functionality and a graphical user interface to the database system. RasDaMan, a commercial array DBMS whose prototype has been developed by FORWISS, is designed for raster data of arbitrary dimensionality and base type, which makes it a powerful storage system for all types of rastered data. This generality calls for a similarily flexible visualization tool for data stored in the database. rView has been designed as a generic visualization tool with very few restrictions regarding dimensionality and base (i.e., array cell) type; among other things, it provides several visualization techniques like texture mapping, voxel- and heightfield rendering, which may be combined with user-configurable mappings to the RGB colour space.
