A stereo pair allows you to view raster maps, scanned photographs or images in stereo, using a stereoscope mounted onto your monitor or red-green or red-blue glasses (anaglyph).
A stereo pair can be calculated:
- with the Epipolar stereo pair operation which requires two raster maps with overlap as input, for instance two scanned aerial photographs with overlap; in the output stereo pair you can view the area of overlap in stereo;
- with the Stereo pair from DTM operation which a single raster map as input, for instance a scanned photograph or an image, and a Digital Terrain Model (DTM); in the output stereo pair, you can view the whole area of the input map displayed over the DTM in stereo.
A stereo pair is automatically calculated when it is opened for display. The stereo pair then contains:
- two resampled output raster maps,
- where each raster map uses a new georeference which retains original coordinates.
A stereo pair can be displayed:
- in a stereoscope window, while using a stereoscope, and
- as an anaglyph in a map window, while using red-green or red-blue glasses.
