How to get the lat/long info from Google Maps?
On Google Maps, You can right-click a location on the map and select "What's here?" The coordinates of that location will automatically appear in the Search box at the top of the page.

Some problems:

1. Google maps uses a protection mechanism to keep a good quality of service. If one makes too much requests, google map will add its IP address to a blacklist, and you may see a message:

403 forbidden

If this happend, Google Maps Terrain Downloader will show a messge in log window: May be your IP is banned by Google. Then you must wait for some time or change to another IP.

2. For some area, there are not high precision images on google's server, so may be caused a error when you try to download such images. If this happened, you need to set smaller zoom level to download. (The max zoom level is 15)
