How to get the latitude/longitude information from Google Maps?
You can right-click a location on the map(http://maps.google.com) and select "What's here?" , The coordinates of that location will automatically appear in the Search box at the top of the page.
4, Define the zoom level. The zoom level defines the image precision. For trial version, the max zoom level is 13, so you can not download high precision images.
After downloading, there will be a file named as *.ftl, if there are some files failed or missed, you can re-download them: menu "tools"->"re-download failed files".
You can view downloaded maps without combining them into one big BMP.
Then open a task from menu "File"->"Open task..." to view the map.
We provide a tool : Combiner.exe. You can run it from menu "Tools"->"Map Combiner".
If the bmp file size is too big, you can use tool "BMP Splitter" to split it into some small bmp files.
1. Google map 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:
If this happend, Satellite Maps 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 happend, you need to set smaller zoom size to download. (For most areas, the max zoom level is 18)
Click menu->'Export toMBTiles db', then will show this window:
There are 3 types of db that you can choose.
And if you select MBtiles format, after exporting, you can view this .mbtiles file with MBTiles Viewer:
You can also use the mbtiles file in some Android or IOS Apps.
There are two methods to know the longitude and latitude of every downloaded image.

google earth images downloder: It can download images (including historical imagery) from google earth servers, not google maps.
After exporting all downloaded tiles into a sqlite database, then you can use the sqlite file in some Android apps, such like RMaps and OruxMaps.
For RMaps: When you finished export tiles to sqlite database with export type 'For RMaps', you will get a file: your_task_name.gmd.sqlitedb, then copy it to your Android device, to your RMaps installed path, might be like '/sdcard/rmaps/maps/', then refresh your RMaps offline maps, you will see a new offline maps "your_task_name_gmd.sqlitedb".
For OruxMaps: When you finished export tiles to sqlite database with export type 'For Oruxmaps', you will get two files: your_task_name.gmd.otrk2, your_task_name.gmd.OruxMapsImages.db, you need to rename the your_task_name.gmd.OruxMapsImages.db to OruxMapsImages.db, then on your Android device, in your OruxMaps installed path, might be like '/storage/emulated/0/oruxmaps/mapfiles/', create a new folder suchlike 'exmaple', then copy "OruxMapsImages.db" and "your_task_name.gmd.otrk2.xml" to this folder, refresh your oruxmaps offline maps, you will see a new offline maps "your_task_name_gmdmap".
