I need to make an orthophoto from google-earth. My orthophoto covers a large area and whenever I save the image in google-earth and put it in the Arcmap to rectify it , the image has very large resolution. I have found a software called "Google Satellite Maps Downloader" (which is not free). This software takes images for smaller areas from google-earth and stick them together, providing an ortho photo with better resolution. Unfortunately my orthophoto is for a big area and the image which I get from the free version of this software still has a bad quality. I was wondering if there is another way to get high quality satellite image from google-earth?
The Answer is that you don't do something like this.
Firstly, the data in Google Earth, isn't raw, and has been processed in a variety of ways, and can have locational and radiometric problems.
Secondly, and more importantly, the Terms and Conditions of Google Earth, prohibit the usage of data in such a way.
You are better off either purchasing such data from commercial vendors, or finding it from local government or other such similar places.
