Raster and Vector Format Support

Currently TITAN supports raster and vector formats via GDAL/OGR by default. With an ERDAS IMAGINE plugin due out August 2008 TITAN will to tie into IMAGINE libraries, greatly extending TITAN raster format support. A user must have ERDAS IMAGINE installed for this plugin to work.

IMAGINE libraries support some of the same formats as GDAL. IMAGINE libraries can override format support by GDAL, meaning, if IMAGINE is installed then it can be used for all formats it recognizes with exception of ECW/ECWP. If IMAGINE is not there then TITAN falls back on GDAL. This will be a preference setting.

For ECW/ECWP, we have written our own fast implementation available as part of the TITAN Client download August 2008.

Formats supported by GDAL/OGR: These formats are supported to the extent which the open source GDAL/OGR libraries are capable of loading. If you would like to add your own formats or require support for trouble with an existing format, please visit the Open Source Geospatial Foundation page for GDAL/OGR.
