One issue with the current version of Google Earth is you can't show subsurface information. GE doesn't let you show data below its 3D rendered surface. So, for example, showing underground geological features, or wells for example. Valery Hronusov from Russia's Academy of Science in Perm, Russia has come up with an interesting innovation He has used KMLer application to convert a GIS dataset showing an oil repository Google Earth File. You must have GE installed. and related information. His innovation is to show the sub-surface data above the site where it is located underground. Valery is a very innovative guy with lots of interesting data at his fingertips. see KMLer sites [hide] http://kmler.geoblogspot.com/ [/hide] nice idea, dont you :tongue:

If the 4 images that you have are from the same sensor type (RapidEye ? ), then you can make a mosaic using, for example, the ERDAS software. Here is a tutorial for making the mosaic in ERDAS, step-by-step : http://www.gis.usu.edu/~alex/WILD6750/Lab05/Lab05/Lab5_Mosaic_TourGuide.pdf Just like the LANDSAT image mosaic. After you make the mosaic, then you can use the Supervised image classification image. Here you can see a video tutorial, using ERDAS software: http://www.youtube.com/watch?v=I1FwzIC7XlU Good luck !
