Hello, I have carried out a series of Georeferencing tasks in ERDAS Imagine for an assignment, however I did not record the type of georeferencing used. is it possible to georeference MODIS image in ERDAS IMAGINE by using Google Earth as to point out if you are going to use Google Earth for georeferencing. This video teaches steps of Georeferencing an Image or map by ERDAS imagine ?v=aYNZ8tl4eZ4.

Thanks for your input, could you please provide me feoreferencing anything that might help to start? Georefeerencing documentation or articles may be a great help of me. There’s help files and example work flows included in the Help section of the software, but here’s a couple of links that may be useful:. Thanks for your help and support, I had the chance to look at the documentation, then I come up with the following procedure, Please have a look at it and correct me if I am wrong.


Georeference images based on XYZ GCPs points (not only XY)

That is the correct procedure. This 3D model requires that GCPs are well distributed across the image horizontally and vertically. After the model is solved you should check your RMS error before resampling. Thanks Guys, this was really helpful, I have attached a manual that I have developed for knowledge sharing, but I wonder if I can show the Z value for the georeferenced image just to make sure that everything is ok. However, using the z values should have helped constrain the model so checking the x,y coordinates prefereably against stand alone check points will show georeferebcing the true accuracy of your georeferencing.
