Hello,
We have to do a photo-interpretation project. We have to display
simultaneously TWO data : one raster raw data (to capture vector features
from) + another raster data to assist in the interpretation. So we would
like divide classic qgis interface into 2 views. Indeed we would like
display these 2 raster data thanks to a synchronized view.
Displaying view left : raw data. Displaying view right : assist reference
Is it possible to do that with grass? If not is it possible to do that with
another soft or application?
In advance, thank you to throw light for me.
Regards.

This functionality is available in GRASS7 via the Map Swipe tool (g.gui.mapswipe) when you set it to 'mirror mode'.

As far as I know, the options are:
1) the g.gui.mapswipe wx-GUI module in GRASS GIS ver. 7,
<http://grass.osgeo.org/grass70/manuals/g.gui.mapswipe.html> offers mirrored
view or "sliding over" for 2 maps. It's really nice but lacks of "live
querying of raster value under the pointer" for example.
2) the Dockable Mirror Map plugin in QGIS,
<http://hub.qgis.org/projects/dockablemirrormap> which offers 2 or more simlpe
mirrors of selected layers (I think both, raster and vector).
3) OpenEV from the FWTools collection, <http://openev.sourceforge.net/>
Personally, I would recommend the OpenEV Viewer. It is _still_ the fastest
raster/vector viewer alive (at least I experience it that way). You can open 2
or more views and "link" them so as you can simultaneously view 2 or more
raster/vector maps supported by a "mirrored" cursor. You can even create/edit
vector layers (points, lines, polygons). It's simply superbe for image
interpretation and, I'd say, exactly what you need!
Best of success, Nikos
