PointCloudValueFilter
require(["esri/layers/pointCloudFilters/PointCloudValueFilter"], function(PointCloudValueFilter) { /* code goes here */ });esri/layers/pointCloudFilters/PointCloudValueFilterEvery lidar point can have a classification that defines the type of surface that reflected the laser pulse. The different categories (for example building, high vegetation, ground) are defined using numeric integer codes in the LAS files. The full list of categories including the corresponding codes can be found in the LAS specification.
PointCloudValueFilter is used to filter points based on the category that they belong to. For example, to display only points that belong to vegetation, the following filter can be set on the layer:
const pcLayer = new PointCloudLayer({
url: "https://tiles.arcgis.com/tiles/Imiq6naek6ZWdour/arcgis/rest/services/PointCloud_urban/SceneServer",
filters: [{
type: "value",
field: "CLASS_CODE",
mode: "include",
// values include low, medium and high vegetation
values: [3, 4, 5]
}]
});
