MapTool 0.9.1 for WebOS

I created a new mapping application for WebOS called MapTool:

  • It displays maps from the OpenStreetMap project
  • shows your current position (and allows to send your position by email)
  • a selected target
  • direction and distance from your current position to the target
  • your current track (and can send it as gpx file by email)
  • the real ground elevation at your current position and also
  • allows the use of offline maps.

Offline maps can be created using this adapted Java tool from here: Tool for offline download: here
The offline maps are a couple of PNG files which has to be in a folder called .MapTool (the leading dot is important!) on the internal volume of your WebOS device. Just use the tool to download the tiles and copy them into the freshly created .MapTool folder after connecting the Pré as USB drive to your desktop computer.

If you want you can replace some of the maps with your own, but ensure you use the same naming, bounding box and image size as the OpenStreetMap project for its tiles.

The official thread about it, is here: http://forums.precentral.net/showthread.php?p=2099438

Some general usage infos:

Start the app, it will try to get your position using GPS. In same cases it will take some time to get your position, then it might just use a rough assumption. You can see the error of your position location in the bottom info strip.

The app will just starting logging your position, you can see your track in blue and in the bottom strip also the ID of your track (date + time of the starting point).

The app follows your position and downloads OSM tiles whenever necessary, use + and – to zoom in or out. Use the reload button to have it refresh the map tiles in case something went wrong. When you start moving the map, it will release the connection to your current position and the zoom-level display will display “move”. Click on it to access the list of targets or to jump back to your current position.

Use the send button to send your current location or the current track by email.

Use the menu to access the settings. Here you can switch the different OSM renderers (use the refresh button to reload the tiles). Also you can specify the error level which will used to draw your path or to convert the log into gpx. A good value is below 100 meters (sorry for only supporting metric units).

The bottom strip also shows you the altitude which the GPS reports and the elevation of the ground as it is stored in the NASA database. Therefore MapTool asks about the elevation value every 10 seconds. It will be adjustable in a later update.

Also I’m glad to announce the appearing of OGCOpenInfo in the official AppCatalog. A very handy tool for all passionate “The Open Golf Challenge” players.
