How to download?

See the screen shot. It is very easy to use.

1, Select a Maps type in the left tree. There are 2400+ maps types. You can goto here to see all tiles samples.

2, Enter a task name, such like "mytask.omm". All task files are saved as *.omm. Note: It is recommended to use English characters for task names and avoid using Chinese, Japanese, and other characters to prevent coding errors.
If you want to continue an old task, click button "Open task... ".

3, Define the zoom level scope. The zoom level defines the image precision. For example, if you define "From zoom"=15, "To zoom"=17, then it will download images at zoom=15, 16 ,17. (For trial version, the max zoom level is 13).

4, There are two ways to define the area that you want to download:

The first method: directly input 4 parameters (Left Longitude, Right Longitude, Top Latitude, Bottom Latitude) to define the area scope of images that you want to download. This method defines a rectangle area.

Left Longitude: -180<=value<=180, for East, the value is positive, for West, the value is negative.
Right Longitude:-180<=value<=180, for East, the value is positive, for West, the value is negative.
Top Latitude:-85<=value<=85,for North, the value is positive, for South, the value is negative.
Bottom Latitude:-85<=value<=85,for North, the value is positive, for South, the value is negative.

For longitude and latitude, the input measurement is degree. You can convert the measurement of "Degrees, Minutes,Seconds" to "Degrees" by click menu "Tools->Convert 'Degrees,Minutes,Seconds' to 'Degrees'...".

The second method: use a kml file to define a polygon area. Click checkbox "Use KML to define a Polygon area" , then click button "Load a kml file...", to choose a kml file, then the polygon vertices information will be automatically parsed and the 4 EditBox will also be automatically filled. By this way, it will not download a rectangle, but a polygon area.

Note: the really downloaded area will be extented a little than you inputed coordinates, to ensure that we get each whole tile.

5, Select a path to save the project and downloaded images.

6, Then click button "Start", OK, start downloading now ... !

When downloading, the log window will display the downloading process. When finished, the log will be saved as a file.

When downloading, we can't change maps type and any parameters. The maps types tree and parameters panel will be froze until you click button "Stop".

Note: for some maps type, the button "Custom Parameters" will be enabled, you can click it to set parameters.

We also provide command line support. Click here to see how to start a task from command line.

How to export tiles to sqlite database?

When downloading finished, all small images are saved on your disk. Then you can export them into a sqlite database (MBtiles format).

How to use offline maps in RMaps, Locus Map 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, Locus Map and OruxMaps.

For RMaps: When you finished exporting tiles to sqlite database with export type 'For RMaps or Locus Map', you will get a file: your_task_name.omm.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_omm.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 Locus Map: Same as RMaps, when you finished exporting tiles to sqlite database with export type 'For RMaps or Locus Map', you will get a file: your_task_name.omm.sqlitedb, then copy it to your Android device, to your Locus Maps installed path, might be like '/sdcard/Locus/maps/', then refresh your Locus offline maps, you will see a new offline maps "your_task_name_omm.sqlitedb".

For OruxMaps: When you finished exporting tiles to sqlite database with export type 'For Oruxmaps', you will get two files: your_task_name.omm.otrk2, your_task_name.omm.OruxMapsImages.db, you need to rename the your_task_name.omm.OruxMapsImages.db to OruxMapsImages.db, then on your Android device, in your OruxMaps installed path, might be like '/sdcard/oruxmaps/mapfiles/', create a new folder suchlike 'exmaple', then copy "OruxMapsImages.db" and "your_task_name.omm.otrk2.xml" to this folder, refresh your oruxmaps offline maps, you will see a new offline maps "your_task_name_ommmap".

How to view MBtiles file?

In the main program "Offline Map Maker", click menu 'tools'->'MBTiles Viewer', you can open the MBTiles Viewer. You can use this tool to view MBTiles file.

How to view the offline map in browsers (such as IE, FireFox, Chrome)?

After downloading, for some types of maps, Offline Map Maker will create a HTML file named as "your_task_filename.html", you can just double click to open it and view it in browsers.

A sample using kml file

This is a sample kml file, created by Google Earth, you can get it here. In this file, there is a Polygon.

After combining, you will get a Polygon image:

This is a screen shot when downloading an area defined by kml/gpx file:

It can also support gpx file. This is a sample gpx file, you can get it here.

Some problems

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

Google Error : 403 forbidden

If this happend, the 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.

To avoid IP banned, you can try to set the downloader to pause some minutes.
Click menu "Misc"->"Options", the following window will be displayed: check the checkbox "Set pause to avoid IP banned".

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)

3. Sometimes the program automatically closed suddenly, perhaps you installed cracked version, please uninstall it.
