LMRandomDisplayThreshold

Unit:SDL_geomap
Class:TGeoMap
Declaration:property LMRandomDisplayThreshold: longint;

If several thousand landmarks are to be displayed on a map, the display process may become too slow in order to work with the map efficiently (slow panning, zooming, etc). In order to cope with this situation, TGeoMap allows to display only a random sample of all available landmarks. If the number of landmarks visible on the screen exceeds a threshold, only a random sample of all landmarks will be displayed. The size of this random sample can be set by the property LMRandomDisplayThreshold. By default, the threshold is set to 20000 landmarks.
