I managed to download the map of a field where I wanna set it, by generating contour, I got contour lines with 10 meters distance in GlobalMapper, saved as .map file. After all of those, I tried to open it in Map Editor, and I got an error which I couldn’t understand, below I show you what it’s given; “Could not open C:\Users.... .Reasons: MyMap.OpenMapFromFile: MyMap.MapReaderBody:Line#0, File Record#1 FileCom.GetData: FileCom.GetData_Kernel:after reading 0 data items Invalid floating point operation “ By the way I couldn’t able to upload some images here showing my stages to make it easier to understand, Is it possible to send you via e-mail if you need any more details about how it went wrong. I appreciate, Best regards, Furkan
