Use your own maps¶
Enroute Flight Navigation comes with a set of base maps that cover large parts of the world and are updated frequently. Still, there might be situations where a user would like to use their own base maps.
Where available, some users might prefer to use official ICAO charts of their countries.
Some users might prefer raster maps that follow a different style.
Some users might prefer to install high-detail vector maps for particular regions of interest.
Enroute Flight Navigation is able to import MBTILES file containing raster or vector data. Vector data must follow the standard OpenMapTiles schema. Vector maps are rendered in the same style that Enroute Flight Navigation uses for its own maps. It is possible to install vector maps along with the maps provided by Enroute Flight Navigation, in order to provide higher detail for particular regions of interest.
Import Maps on Android devices¶
If you are using an Android device, you need to transfer the MBTILES file to the device, and open it there. There are many ways to transfer files, but most users will likely do one of the following.
Download the MBTILES file on the Android device with a web browser. The browser will then offer to open the file in Enroute Flight Navigation.
Download the MBTILES file to a desktop computer, connect the device to the desktop computer via USB and then copy the file to the device. Afterwards, the file can be opened by a file management app on the Android device.
Import Maps on Linux Desktop¶
If you are running Enroute Flight Navigation on a Linux Desktop machine, use the file manager to drag-and-drop the file into the main window of the app.
MBTILES files are often extremely large. It is possible that your device becomes unresponsive for a few seconds while copying the file. Also, note that Enroute Flight Navigation will copy the file to its internal data directory. In order to save space, we recommend deleting the MBTILES file once it has been imported.
MBTILES Map Data Sources¶
We are aware of a few websites that offer vector or raster maps that can be used with Enroute Flight Navigation. Please let us know if you know of other map data sources!
The website maptiler data provides excellent vector maps that can be installed alongside the base maps provided by Enroute Flight Navigation, in order to provide high-detail maps for specific regions of interest.
The website open flightmaps provides excellent aviation maps in raster format for a variety of European countries, as well as South Africa and Namibia.
Raster Maps in GeoTIFF format¶
We are aware of websites that offer raster maps in GeoTIFF format. At present, Enroute Flight Navigation cannot handle GeoTIFF files, but there are tools that convert GeoTIFF to MBTILES.
Official ICAO maps for Denmark are available from the danish AIM Naviair
Official ICAO maps for Switzerland are available from the swiss Federal Office of Topography swisstopo
Official VFR raster charts are available from the United States Federal Aviation Administration
Users have successfully used the free tool QGIS to convert GeoTIFF files to MBTILES, which can then be used with Enroute Flight Navigation.
Since QGIS is a powerful tool that is not always easy to use, one user has kindly provided the following short tutorial.
Install QGIS on your desktop computer. On Fedora Linux, we found that the packages provided by the default software repository were outdated and lacked the necessary functionality. We followed the installations instructions on the QGIS website to install a current and full-featured version of the program.
Open QGIS. Create a new project and open the GeoTIFF file in QGIS by dragging-and-dropping the GeoTIFF file into the QGIS window. The content of the GeoTIFF file should become visible.
Choose the menu item “Project/Properties…” to open the dialog window “Project Properties”. There, set the coordinate reference system to EPSG:3857. To locate the reference system, use the text field “Filter” and search for EPSG:3857.
Use the menu items under “View/Panels/…” to ensure that the panels “Layer” and “Layer Styling” are visible. Select the layer of your GeoTIFF file and in the “Layer” panel. Then, go to the “Layer Styling” panel and set “Resampling” to “Bilinear” for better image render quality.
Use the menu items under “View/Panels/…” to ensure that the panel “Processing Toolbox” is visible. Inside the “Processing Toolbox”, double click on “Raster Tools->Generate XYZ Tiles (MBTiles)”. The dialog “Generate XYZ Tiles (MBTiles)” will open. Fill the necessary parameters, as seen in the image below. We found the function “Draw on Map Canvas” useful to specify the map extent. Pay attention to the maximum zoom level, as the time and file size increase significantly after zoom level 12. Depending on the size of your GeoTIFF and on the number of zoom levels you use, it may take a while to generate the MBTILES file.
