You can use map overlay functionality of Sygic, which means showing your geo objects on top of the standard map.
The geo objects needs to be expressed within a single file in json format, called geofile.
The import only occurs at the start of the application, and geo objects are shown on map immediately.
Please note the functionality is enabled under a special license option, resulting your license contains the setting geo=yes.
For the geofile import process you may check the ImportFile API function, which helps you to create a file in the Sygic application file space.
Through the LineString feature you can create a polyline on map.
This example shows the feature to mimick a congestion zone in Bratislava, Slovakia.
Through the Polygon feature you can create a closed region or zone, on which you can monitor vehicle movements for entering or leaving.
The json structure contains the attributes for supporting cross movements identification through the ApiEvent.EVENT_GEOFENCE, which are notificationEnable (for enabling notification events) and notificationData (for identification of a particular region/polygon).
Through the Point feature you can create list of markers on map.
This example shows four markers in the seightseeing zone of Bratislava, Slovakia.
