comment Mosaic Imagery using GDAL Edited
Note that if you use QGIS, the raster merge function simply builds a GDAL gdal_merge command, which you can see in the QGIS user interface.

comment Draw SQL server geometry records as graphics on map using ArcGIS API for WPF 2.4 -can it be done and how?
It certainly doesn't look easy! You're going to have to go through the doco carefully. Maybe someone else with experience using that API can help, though. Here's the relevant doco: help.arcgis.com/en/webapi/wpf/help/index.html#//…. Do you have to stick with a WPF app? WebMapping is much easier!

comment Google Maps API: How to remove terrain from the satellite view?
Can you please provide some more context to your question? Perhaps include some code so that we know what you're doing. I assume this is the javascript api and you're making a webmap.

comment GPS Track Editor to crop tracks with select by clicking start and end points
Hey @Benzo, what you're asking for is not going to be out of the box, I don't think. You could write a plugin to do it. But that online tool actually sounds like a fairly reasonable way to do it. In a desktop GIS, you will need to edit the line feature and manually remove any vertices that you don't want.
