Combine Terrain Layers - One is an Erdas-Imagine-Elevation-Grid with Pyramids

PeterDrexel

Mike,
I Try to calculate the difference between 2 Elevation-Grids, one is stored as ArcAscii and one as Erdas IMG. If I do so and if I am zoomed out far it seams that Globalmapper 13 uses a wrong elevation for the img-file (it seams gm uses the Pyramid-Elevation of the IMG-File rather then the "Hires"-Elevation).
If I zoom into the Dataset and calculate the difference-Model again the result seams OK.
Thanks
Peter

Peter,

I have a likely fix for this. I have placed a new build at http://www.globalmapper.com/global_mapper13.zip with the change for you to try. Simply download that file and extract the contents into your existing v13.xx installation folder to give it a try. If you are using the 64-bit version of Global Mapper, there is a new build at http://www.globalmapper.com/global_mapper13_64bit.zip .

Thanks,

Mike
