[Qgis-user] Feature inquiry: Multiple display windows?

[Sjur Kolberg]

Hello, Qgis community:

I am not yet a QGIS user, but I'd like to know if QGIS supports several map display windows, possibly cooperating.

One of the things I do most in my current GIS (which I am only partly satisfied with) is to compare two rasters. It would be nice to plot them in separate windows, and when pan/zooming around in one, the other would update its extent and show the same area. I also frequently have lots of raster windows up simultaneously, from the QGIS screenshots this does not appear common usage.

To take it even further, the two maps could actually be time series, for instance repeated satellite images and simulated snow cover from a distributed hydrology model. Then also next/previous-buttons could be added to the display windows, again affecting both windows simultaneously.

If I was to program such functionality (in C++, I don't speak Python), would it be standard plugin procedure using QGIS API,or would the display/GUI part of it require deep revisions of existing QGIS code?

Regards :-)
