Tiles downloading

Offline Google Maps tiles have to be downloaded using MissionPlanner's maps prefetch tool.

Supported map types are

• GoogleMap
• GoogleSatelliteMap
• GoogleHybridMap
• GoogleTerrainMap

Launch MissionPlanner, switch to the "PLAN" tab and navigate to your location.

Use CTRL + left mouse button to draw your download region

right mouse button to select the prefetch tool

accept 20 as max zoom level (min is 1)

wait for download to complete, (time depends on the size of the area)

Tiles resizing

Unzip the resize tool (gmapresizetool.zip)

and launch gmapresizetool.exe

User needs to select:

• map type which has to be the same one used in MissionPlanner
• source folder will be automatically set to MissionPlanner download folder
• destination folder which can be the root of the SD card (if mounted) or a temp folder to be eventually copied to the SD card later, please read the notes below!

Note: please double check your destination map tiles path:

• for Ethos use /bitmaps/yaapu/maps (absolute path on your radio SD card)

Note: The resize tool will resize all tiles found in MissionPlanner offline cache, if there are tiles that should not be resized and transfered to the SD card it is necessary to clear the download folder C:\ProgramData\Mission Planner\gmapcache\TileDBv3\en* before starting the map prefetch tool.

Configuration

Once the tiles are copied to the SD card it is necessary to run the Widget Config Tool and enable Google Maps support

Please make sure you have a valid GPS sensor!
