  • SHP, GDOSQL data providers and geometry factories.
  • TIFF, CIT image decoders, where TIFF decoder supports full Adobe® TIFF spec. (all possible image geometry and color schemes), except of GeoTiff tag, which was quite fuzzy at time of implementation.
  • For TIFF also image tiles are supported as specified by Intergraph®
  • SRS and SRS transform (including precise image transforms) with XAML, JSON support for coordinate system and transform storage.
  • legend driven map display components
