MeasureHandler

Members

activeEvt : Event

Activate the event and listen for the current event to get the state of the processor.

areaLabel : Entity

The equivalent measurement mode is Area, and the label area object areaLabel is used to display the area measurement result.

clampMode : Number

Paste object mode.

disLabel : Entity

The equivalent measurement mode is Distance, and the tag entity object disLabel is used to display the spatial distance measurement result.

enableDepthTest : Boolean

Set whether to draw depth detection for the drawing object, which is enabled by default.

hLabel : Entity

The equivalent measurement mode is DVH, and the label entity object hLabel is used to display the horizontal distance measurement result.

measureEvt : Event

Measure the event and listen to the current event to get the measurement result. When the measurement mode is MeasureMode.Distance, the callback result is {distance : distance}. When the measurement mode is MeasureMode.Area, the callback result is {area : area, positions : positions}. When the equivalent mode is MeasureMode.DVH, the callback result is {distance : distance, verticalHeight : vHeight, horizontalDistance : hHeight}.

Example:

var handler = new Cesium.MeasureHandler(viewer,Cesium.MeasureMode.Area);
handler.measureEvt.addEventListener(function(result){
                    var area = result.area > 1000000 ? result.area/1000000 + 'km²' : result.area + '㎡'
                    handler.areaLabel.text = 'area:' + area;
                });

vLabel : Entity

The equivalent measurement mode is DVH or Height, and the label entity object vLabel is used to display the vertical height measurement result.
