gMapMaker+ – with support for TTQV

in .NET Development, GPS-Navigation


gMapMaker+ enables you to download maps from OpenStreetMap, OpenAerialMap, Google, Yahoo or MSN as large scaled image files, that can be used in GPS applications like TTQV or OziExplorer.

gMapMaker was originally developed by Damien Debin. Since Damien no longer has time to contribute to the development of gMapMaker, I decided to add some new features on the latest version 0.7.

The updated version gMapMaker+ V1.0 is available for download here (SetupSourcecode).


Features of gMapMaker + V1.0

The list below shows the added features in comparison to the latest version gMapMaker 0.7:

  • Enhanced graphical user interface: Completely revised graphical user interface, integration of a map dialog to select map sections.
  • Bugfixes: Several download url’s have been corrected and modified
  • Support for TTQV: New option “Build image and TTQV cal” has been added. This option creates a calibration file, which can be imported in TTQV 4x and higher.
  • Support for ECW file format: Along with JPEG, PNG and TIFF, gMapMaker supports also the ECW file format. See installation manual to properly configure this feature.
  • Downloads history: The download settings of all successfully downloaded image files are stored in a logfile and displayed in the history section.
  • Settings: Most of the settings available in gMapMaker can be done in the GUI now
  • Test Button for memory allocation: This button enables you to check the graphical memory for allocation, before start downloading.
