 How to view downloaded maps?

You can view downloaded maps without combining them into one big BMP.
We provide a tool to view the images, you can run it from menu "Tools"->"Map Viewer".

Then open a task from menu "File"->"Open task..." to view the map.


 

How to combine small images into one big map?


After downloading, all small images are saved on your disk. Then you can combine them into one big image map.

We provide a tool : Combiner.exe. You can run it from menu "Tools"->"Map Combiner".


It can output BMP file with a bpw file, it can also create TIFF/JPG/PNG file, and a map file for OziExplorer. You can convert it to other format by yourself using some image tools such like PhotoShop.

Note: if the BMP file size is too large (>4GB), will not create TIFF/JPG/PNG file. But you can use GIS softwares such like Global Mapper to load the bmp and then output to other formats.


 

Some problems

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:

Google Error : 403 forbidden

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 404 error when you try to download such images. If this happened, you need to set smaller zoom size to download. (For most areas, the max zoom level is 18)


 

How to export tiles to sqlite database

There are 3 types of db that you can choose.

How to use offline maps in RMaps or OruxMaps?

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.umd.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_umd.sqlitedb".
Note: when you view the offline maps in RMaps, you need to zoom it to your downloaded zoom level, otherwise, it will show blank maps.

For OruxMaps: When you finished export tiles to sqlite database with export type 'For Oruxmaps', you will get two files: your_task_name.umd.otrk2, your_task_name.umd.OruxMapsImages.db, you need to rename the your_task_name.umd.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.umd.otrk2.xml" to this folder, refresh your oruxmaps offline maps, you will see a new offline maps "your_task_name_umdmap".
