Map View is the view that displays Points of Interests (POI’s) on a base map.

Prerequisites

In newer versions of UBIK^® Android, Open Street Maps (OSM) is used instead of Google Maps; hence, no Google Play Services are required anymore ().

For older versions, the following is valid:

Google Play Services Missing

In the map view, UBIK^® integrates Google Maps which requires Google Play Services. If the latter is not available on a device, UBIK^® can still be installed and most of its features will still function. However, the map view will not be accessible and a notification will be shown in that case ().

Visualization

Map view

A typical Map view consists of the base map, top map menu, bottom navigation menu, location button, zoom buttons.

Base map

The base map typically displays all the Geo content according to the rules described below. Different objects are represented by different icons on the map.

The rules regarding what content should be displayed are as follows:

• The object has to be a Geo content
• If a POI group is currently open/active, objects that are shown are:
  • POI group items that belong to the current group;
  • Objects that are not POI group items;
• If a map layer is currently selected, objects that are shown are:
  • Items of the current Map Layer;
  • Objects that are not map layer items.
• If there is an object as the context of the map view (e.g. User opens a Geo content in the map), that object is displayed in addition to whatever else is.
• If an Image Ground overlay is configured.
  • This overlays are used to visualize building schemes on the map.

Objects have to pass all the checks above in order to be shown.

Before Version 2.4.3 - Android objects had to be in the Infrastructure in order to be shown at all.
