78. Map Themes

78.1. Installing Map Themes

Additional map themes can be installed in the directory set in options on page Cache and Files, section Map Display Themes. You have to enter a valid path there before using map themes.

New maps come as downloads with different directory structures. Some contain the base directory data\maps\earth in the downloaded archive and some do not. Each map installed theme has to consist of a directory containing the related .dgml and other files. The name of the map directory and the .dgml file have to match. For example .../norway-topo/norway-topo.dgml.

Note that you have to restart Little Navmap to see the new map themes.

The menu View -> Theme in the main menu and the toolbar drop down box will receive an entry for each additional map theme.

The option Show Country and City Names is enabled for all additional map themes but might not work depending on properties defined in the map’s DGML file.

Note

Some map themes require an user account and an API key or token to use them. See options page Map Keys for more information.

Installing a map theme from a ZIP file OpenStreetMap French.zip. The compressed file contains the subdirectory data\maps\earth. You have to copy the directory osm-fr containing the file osm-fr.dgml into your selected map theme directory Documents\Little Navmap Files\Map Themes.

You have to restart Little Navmap to see the new map themes. Click image to enlarge.

Tip

Also check out the Little Navmap Support Forum at AVSIM and Little Navmap Downloads - Map Themes for more map themes.

Note

Little Navmap shows an error message on startup if map themes are broken or not installed properly. A message will also be shown if a known discontinued map theme service is detected.

Fix the issues by removing the broken or duplicate map themes and restart Little Navmap.

Warning

Do not use the path .../data/maps/earth in the installation directory to install maps. This location is deprecated.
