Dynamic zooming has an optional hysteresis feature to prevent the map jumping between zooms when vehicle speed is hovering about the zoom-out limit. Vehicle speed must drop HysteresisLimit below the zoom out speed before the map will zoom into the next lowest level.

Namespace:  Telogis.GeoBase.Navigation
Assembly:  geobase.net (in geobase.net.dll) Version: 4.99.0.0
Syntax
Copy
public SpeedValue HysteresisLimit { get; set; }

Property Value

Type: SpeedValue
Remarks
The HysteresisLimit is a buffer between crossover levels specifying the absolute minimum speed spacing between them. For example, a HysteresisLimit value of 15 dictates that no crossover levels can be less than 15 km/h from one another. The HysteresisLimit also prevents the map zoom jumping between two zoom levels when speed sits near a zoom-out boundary. For example, with a crossover value of '50' and a HysteresisLimit value of '10', the map will zoom out when the vehicle speed reaches 50 km/h, but will not zoom in again until the vehicle's speed has dropped below 40 km/h. When a NavigationManager is constructed, a default HysteresisLimit of 10 km/h is set. To clear this default value and set your own, DynamicZoomSettings.Clear(); should be used.
Examples
C#
Copy
nm.MapControlMode = NavigationManager.MapMode.DynamicZooms;
// Clear default values
nm.DynamicZoomSettings.Clear();
// Set a new HysteresisLimit of 15 km/h
nm.DynamicZoomSettings.HysteresisLimit = new SpeedValue(15, SpeedUnit.KilometersPerHour);
