Web scene layers are cached web layers that are optimized for displaying a large amount of 3D features. Web scene layers can include 3D point layers, 3D point cloud scene layers, 3D object layers, or integrated meshes. Because web scene layers are cached, the symbology, labeling, and elevation settings cannot be altered.
For more information on sharing web scene layers from ArcGIS Pro, see Web scene layer.
Point scene layers
To ensure fast visualization in all clients, cached scene layers are used to display larger amounts of point data in a web scene. For example, you may use a scene layer to display the trees in a city using preset layers.
Point scene layers are automatically thinned to improve performance and visibility at smaller scales. Automatic thinning means that not all features are displayed at small scales; as you zoom in, additional features are displayed.
Point cloud scene layer
Point cloud scene layers provide fast display of large volumes of symbolized and filtered point cloud data. They are optimized for the display and sharing of many kinds of sensor data, including lidar. Point cloud scene layers are built directly from a LAS dataset layer and helps support sharing 3D point content across the platform. For more information on using a point cloud scene layer in ArcGIS Pro, see Point cloud scene layer in ArcGIS Pro.
A point cloud scene layer can be created using the Create Scene Layer Package geoprocessing tool, which generates an slpk file on disk. This file can then be previewed directly inside ArcGIS Pro, and then uploaded to Portal or ArcGIS Online using the Share Package geoprocessing tool to be published as a service layer.
3D object scene layers
3D object scene layers can be used to represent and visualize objects such as buildings that are explicitly modeled in three dimensions.
Integrated mesh scene layers
3D mesh data is typically captured by an automated process for constructing 3D objects out of large sets of overlapping imagery. The result integrates the original input image information as a textured mesh including 3D objects, such as buildings and trees, and elevation information. Integrated mesh scene layers are generally created for citywide 3D mapping; they are often captured by drone and cannot be restyled.
When an integrated mesh in a projected coordinate system is added to a scene, it is added in local view with the basemap and default elevation source removed. An integrated mesh with a geographic coordinate system such as WGS 1984 is added to a global scene with both the default basemap and elevation source.
