Satellite Image Download

Note: the max combining size must larger than the total size of a row of images or the max combining size will be increased to that one. For example, if you set the max combing size to 1000M, but the size of a row of images is 1100M, then the max combing size will be 1100M.

When each time combined image file reach the max combining size , the combined image file will be saved and a new file will be created to continue the combining. For example, if the max combining size is 1000M and the total file size of the downloaded image files is 5500M, after combining, there will be six combined files. Since the restriction of the max size of a BMP file, the max combining size will not exceed the 4000M.

Getting Started

With a few steps, you can easily download the images you want.

Some problems:

1. Google Server employs a protection mechanism to keep a good quality of their service. If one makes too much requests, Google Server will add its IP address to a blacklist for a period of time.

If this happens, Satellite Images Download will show a message in log window: Maybe your IP has been banned by Google. In this condition, you will have to wait for some time to continue the downloading or change to another IP.

2. For some area, high-resolution images maybe unavailable now, so an error will occur when you try to download these images. If this happens, Satellite Images Download will show a message in log window: Maybe there is no image on this zoom scale . In this condition, you will have to reduce the zoom value. (For most areas, the max zoom value is 18)
