First of all this is my first post here and also the first post about GIS so sorry if i'll talk nonsense here.
I have an large jpeg and also tiff which are the same map(image) 45568x37632 which i have downloaded it from Google Earth with Google Maps Downloader.
I want to georeference one of those(jpeg or tiff file) in ArcMap 10.4
With Google Maps Downloader you can create a georeferenced tiff;so i opened this in ArcMap but it came stretched horizontally like that
Here are the properties:
I tried also with the jpeg which was not georeferenced in Google Maps Downloader
I understand that Google Maps use WGS1984 Coordinate System so i used that with the jpeg.
The Data Frame Properties is also set to WGS1984
I used control points with coordinates taken from Google Earth in Decimal Degrees,but after I applied them(georeference)
the jpeg layer came stretched like the georeferenced tiff with Google Maps Downloader.
Here is the original jpeg:
and here is after using control points:
So what's the catch here?What I'm doing wrong?
Second issue: I tried to rectify the georeferenced tiff(which has 1.63 GB) and it took 10 hours to save it,and the result was only black tiff,over 12 GB.
Is that normal? I'm on Windows 8.1 Pro,I74790,16gb ram,GTX 770
Third issue:Does anybody knows by the way,why this image has that darkened bottom part in Google Earth? because in Google Maps it doesn't have it.
Or if somebody knows a way to download very high resolution images like this one,from Google Earth/Maps but to be able to download from historical imagery?
Thank You and I apologize if I'm asking too much.
