It's rather slow Walt.

FWIW I've been spending time w/ Qgis wien. It's obviously much faster than Mapwindow. I was able to import USGS 1/9 arc .img files, reform them to the older gis format .tif, save, and import them into DEMEX where I created MSTS terrain... and did so w/o getting lost in all the other functionality these programs all have.

Well, if I do anything at all with exploring GIS possibilities, I'll do MapWindow and you do Qgis. We can share test cases and each write reports. But I'm not going to do anything at all in that area until I'm finished with Virtual Globes.

Some of the reasons why QGIS may be faster it's written in C++, along with QT GUI also written in C++. No worries about garbage collection. Of course I assume your comparing apples, both QGIS MapWindonw running on a 64 bit system.

Yes.

The shared comparison I suggested was intended to be only a functional comparison. Obviously, Dave and I are likely to have systems widely different in performance.

If I test the GIS water, it will be with MapWindow. For me, that's the wiser choice. (For example, although I know C++ and have written applications with it, I choose not to go back to it. I wouldn't work with the Unreal engine for the same reason. It's an age and energy thing.) This choice has nothing to do with Open Rails. I'm only offering up the assessment.

Dave, MapWindow Six is kind of like the Open Rails route editor. That release is in the queue for future development. The main thrust of Six will put MapWindow on purely a DotSpatial API base.

The current production release of MapWindow is 4.x. The work now underway is Release 5. That is said to be an effort to put the program on a modern programming practice base. Sound familiar? It should.
