OpenOrienteering Mapper 20201026.1

OpenOrienteering Mapper is an orienteering mapmaking program and provides a free alternative to the existing proprietary solution. Its main advantages compared to it are: Open Source: The program is completely free, every programmer can improve it. Cross-platform: The program works on Android, Windows, macOS and Linux. It has been used to produce maps for classical orienteering, MTBO and radio orienteering races. All required functions for drawing maps are implemented and the program works very stable. So it can be considered ready for productive use, although it is like always a good idea to keep backups of your files. We are happy about feedback to the program.

20201026.127 Oct 2020 06:45 minor feature: The Paint-on-Template feature (aka Scribbling) learned to fill areas (solid or pattern, GH-1242) and to draw in background. When GNSS tracking is enabled, the viewport can follow the location (aka Tourist mode, GH-987). Templates are loaded after initial map loading, with feedback (but still in foreground, i.e. blocking). Basic support for Geospatial PDF templates (via Poppler and GDAL). Upscaled icons, and increased menu item size, for better usability on Android. Minor OCD support improvements, e.g. export of template visibility (GH-1236). The Find-object tool may be used to visit one match after the other (GH-1512). The object query language was extended with NOT and SYMBOL (GH-1631), adding even more power to CRT files. Translations were updated again. Third-party components were updated again (Qt 5.12.9, PROJ 7.1.1, GDAL 3.1.3, graphics formats, cf. Superbuild). Placement of OCD templates in OCD maps (GH-1302). OCD import of hatch/structure orientation (GH-1677). Template alignment and list widget quirks. Georeferencing quirks. DPI selection for image export (GH-1271). Default location source on Android (GH-1629). Windows (7 and up): You can choose between an installer (*.exe) and a portable archive (*.zip). For most modern Windows installations, you should choose the x64 bit packages. The x86 will also run on all Windows desktops but are limited by the 32-bit architecture. macOS (10.12 and up): You may need to run the app via Ctrl+Click the first time, in order to allow it to run despite coming from an "unknown source". Android (4.1 and up): You can try arm64-v8a package on newer devices. Otherwise, the armeabi-v7a package should work for most older devices. Note that you will have to allow installation "from unknown sources". The armeabi-v7a package is also available from the IzzyOnDroid F-Droid Repository.
