Saving map for offline usage
To save the map with elevation information around the camera's view point for offline usage, click Map Options icon (or click the mouse right-button) and click on Offline map - the map caching progress will be initiated.
Cache file with 1 km radius will be saved for current map provider. Wait until the animated progress bar at the bottom of UgCS window will disappear. Do not forget to press Offline map button after any camera view point changing for getting proper data.
Parameter 'cacheRadius' in map.xml configuration file allows to control radius of map caching area.
It is possible to save several view points on the map - select 'Save view point' to save current location on the map with set camera tilt.
To return to the saved map location and route view, select saved view point.
