Lurker Posted July 31, 2013 Report Share Posted July 31, 2013 so those four images are in different bands covering same area? to make sure, or an area with 4 image coverage (tilled image) ? Quote Link to comment Share on other sites More sharing options...
Arhanghelul Posted July 31, 2013 Report Share Posted July 31, 2013 (edited) 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 !
