To access the map settings, tap at the top left corner of the screen.

You can select the software platform that provides the maps and their rendering. The default option is Google Maps. Alternatively, you can choose the OpenStreetMap platform (https://www.openstreetmap.org/). OpenStreetMap is an open-source project that allows users to add their own objects to the map.

Google Maps allows you to choose between different types of maps—schematic, satellite photo, or hybrid version— and works only in online mode, meaning the displayed sections of the map are downloaded by the application from the Google server.

OpenStreetMap displays the map only as a schema. You can choose between online mode, where the map is downloaded as raster image tiles from the servers of OpenStreetMap partner companies, and offline mode, where preloaded files with vector maps are used for display (see below for details). OpenStreetMap draws markers much faster than Google Maps, making it more convenient for very large tracks.

By default, only the basic map settings are shown. To view all the settings, select "Advanced" in the first group of settings. Later in the text, the advanced settings are highlighted in blue.

The settings for Google Maps and OpenStreetMap differ slightly. The specific differences are listed at the end of the page.

Marker colors indicate: select the value that determines how the markers are colored. This can be either the dose rate or the count rate.

Never: The coordinates of your smartphone's current location are not stored in the database (log).

Only when recording a track: The coordinates of your smartphone's current location are entered into the database only when recording a track. This enables you to partially recover a track from the base log as a pseudo track.

Always: If enabled, the location is recorded in the database along with the other information. In the future, you can view the pseudo track on the map and observe changes in the radiation situation related to the selected location. Avoid enabling this option unnecessarily, as determining the location significantly increases the smartphone's power consumption.

Location resolution and distance between markers on the map: If the smartphone's location changes by more than the specified number of meters from the previous one, a new point is recorded in the track. Avoid setting values too low, as this will cause the smartphone's GPS module to work more intensively, rapidly increasing the number of track points and slowing down the rendering of the track on the map.

Ignore a location if its measurement accuracy is worse than:If the accuracy of the position measurement is worse (greater than) the specified value, the application will ignore the system message about the position change. For example, if you specify to ignore locations with a measurement accuracy worse than 20 meters, and the system reports that the location has changed, but the measurement accuracy is ± 22 meters, then this location change will be ignored.

Ignore a location if the distance to the previous point is less than:If the distance between the previous point and the current point is less than the specified value, the application will ignore the system message about the location change. The combination of the last two options helps eliminate situations where the system reports small changes in geolocation coordinates measured with poor accuracy.

In the “Markers” group, you can choose how the circle markers will be displayed on the map:

Some location-related settings can be found in the application settings.

You can import a track using the button. The system file picker will open.

The Radiacode application can export a track in several formats:

When exporting a track in the .kmz format, you can configure the following settings:

In the “Map type” field, you can choose how the map will appear: a diagram, a satellite photo, or a hybrid version.

Theme for the "Scheme" mode: you can choose a map theme: light (the default), dark, or let the app select the theme based on the smartphone's light sensor. In this case, the theme switches automatically if the light level changes and remains stable for 10 seconds. Due to the use of the ambient light sensor, the application's power consumption may increase slightly.

Do not add markers to the map outside the displayed area: this option can optimize map performance when there are many points in the track. If the number of points exceeds 500, then when moving and scaling the map, all markers are removed and only those within the visible map area are re-added. This causes track markers to blink, but the map is rendered faster due to the limited number of markers. The effectiveness of this technology depends on the ratio of visible markers to their total number in the track (if the entire track is displayed on the map, the efficiency may even be negative), as well as the speed of the smartphone.

Show traffic:Request the maps to display traffic on the roads. If traffic information is available, the maps will show it.

OpenStreetMap map source: by default (online), the option where the map is loaded as pre-rendered raster image tiles from the servers of OpenStreetMap's partner companies is used. The alternative is to work with maps in offline mode, meaning no Internet connection is required. The maps are sourced from vector map files, which you need to download yourself from one of the sites listed on the page https://download.mapsforge.org/ (it's more convenient to do this with a computer) and place them in the RadiaCode app folder on your smartphone named /sdcard/Android/data/com.almacode.radiacode/files/Maps.

Currently, the Mapsforge library does not support working with files due to the access restrictions imposed by Android system versions 11+. Therefore, the map files must be placed in the folder mentioned above.

In offline mode, map rendering, which involves converting vector information into an image, is performed by the Mapsforge library integrated into the application. This process requires some smartphone processing resources. When you move the map around the screen and zoom in, the app will consume more power than in online mode.

Map theme: In offline mode, you can choose between two display options, which primarily differ in their color palettes.

Image scaling: In online mode, the application retrieves low-resolution images of map areas. On high-resolution smartphone screens, the text on these maps may appear too small and might require image scaling. After scaling, the final image might look slightly blurry, but you must balance image quality with text size. You can find the optimal ratio by manually adjusting the scale. Offline mode doesn't have this issue, but you can still experiment with the scale.
