Overlay manager

The overlay manager manages all types of overlays such as points of interests (POIs), freehand drawings, KML overlays, and bookmarks.

Adding overlays (“+” button)

The following options are available when pressing the “+” button in the “Overlays” tab:

• Add folder: Adds a new folder.
• Bookmark overlay: Adds a new bookmark overlay. A bookmark overlay is a collection of bookmarks.
• Import: Import an overlay from a file (e.g., Mapsforge POI, GPX, KML, etc.).
• Import KML/KMZ overlay: This option imports KML files containing shapes (e.g., lines, circles, etc.). See also: Using KML NetworkLink tags in Cartograph Maps for online overlays.
• Import CSV file: A tool for importing tables of waypoints stored as CSV files.

Top toolbar menu

The top toolbar menu offers the following options:

• Settings:
  • Keep manager open when clicked outside: If enabled, then the Overlay manager view will not close when you click outside of the view.
  • Cluster waypoints: If enabled then waypoints are clustered leading to a less crowded map.
  • Import KML/KMZ files always as bookmarks: If enabled then KML files are always imported as bookmarks (recommended). If disabled then KML files are loaded as overlays which is only recommended for KML containing polygons and tracks but very few waypoints.
  • Deactivate track with eye icon: By default tracks are unloaded when the eye icon is pressed. If this option is enabled then the track is just hidden in the map view. This function is useful if you want to quickly toggle tracks on/off.
  • Max. number waypoints: The maximum number of waypoints shown on the map for each overlay. A high value can have a significant negative impact on performance.
  • Enable audio waypoint alerts: If checked then a sound is played when heading towards a waypoint with an attached alert.
  • Enable visual waypoint alerts: If checked then a red warning banner is displayed when heading towards a waypoint with an attached alert.
  • Default alert distance: The distance when an alert is played when heading toward a waypoint.
  • Name pattern: A default name pattern used when creating new bookmarks and waypointss. More details are available here.
• Check for updates: Check if there are updates available for overlays. This function works only for overlays with associated download urls.
• Unload all: Unloads all overlays from the map view.
• Help: This page.

Overlay entry popup menu

The overlay entry popup menu offers the following options (the available options depend on the overlay type):

• Load: Loads the overlay into the map view.
• Unload: Removes the overlay from the map view.
• Reload: Reloads an active overlay in the map view.
• Circular distance: Shows circular distance measurement circles around all currently visible waypoints from the selected overlay.
• Zoom to: Zooms the map view so that the bounding box of the overlay is completely visible.
• Calculate bounding box: Re-calculates the overlay’s bounding box.
• Properties: Shows overlay dependent overlay properties. For instance:
  • Name: The overlay name.
  • Exclude from sync: If checked then the overlay is not synced during cloud sync (see Cloud backup).
  • Archived: If checked then the overlay does not appear in selection lists.
  • Min./Max. zoom: The zoom level range where the overlay is visible.
  • Bounding box: The bounding box covering all points in the overlay.
  • Enable remote KML network links (KML overlays only): If enabled, then KML overlay data defined in “NetworkLink” KML tags is downloaded on-the fly from remote servers.
• Delete: Deletes the overlay and the underlying file if the following conditions are met:
  1. The overlay file is located in the Cartograph “Offline overlays” directory and
  2. The overlay file is not used by another overlay.
• Move to folder: Moves the overlay to another folder.
• Clone: Create a copy of the overlay.
• Redownload/Update: Re-downloads the overlay file from the webserver. This option is only available if the overlay is associated with a download url.
• Circular distance: Creates circular distance measurement circles around all currently visible overlay points.
• Calculate bounding box: Re-calculates the overlay’s bounding box.
• Import file: Imports a file with waypoints into the selected bookmark overlay.
• Export: Exports the selected bookmark overlay into a (GPX/KML) file.

Overlay folder popup menu

The overlay folder popup menu offers the following options:

• Delete: Deletes the folder and old overlays in the folder.
• Rename: Renames the folder.
• Move to folder: Moves the folder to another folder.
• Load: Loads all overlays in the folder.
• Unload: Unloads all overlays in the folder.
