A point cloud scene layer can be created using the Create Point Cloud Scene Layer Package geoprocessing tool, which generates a scene layer package file (.slpk).
A point cloud scene layer package file can be displayed in ArcGIS Pro and then uploaded to ArcGIS Enterprise or ArcGIS Online using the Share Package geoprocessing tool to publish it as a service layer. The input data type for a point cloud scene layer package in ArcGIS Pro is a LAS dataset layer or an individual or folder of LAS, ZLAS or LAZ file(s).
A LAS dataset that references LAS and ZLAS files can also be used to create a point cloud scene layer. Any symbology and point filtering that has been applied to the points of a LAS dataset layer will be used to create the point cloud scene layer. A default elevation symbology and no point filtering will be used to create a point cloud scene layer when individual files or a folder of files (LAS, ZLAS, LAZ) is used as input. To optimize the point cloud data and define properties such as symbology and filtering use the LAS dataset as input. For more information on point filtering see: Change filter options for a point cloud scene layer.
Surface constraints are ignored if they are referenced by an input LAS dataset layer. The input LAS dataset layer must be a layer in the scene or lyrx file. TIN-based rendering symbology of the input LAS dataset is not supported by a point cloud scene layer. A stretch renderer with elevation will be used for the output scene layer package in this case.
To create a point cloud scene layer using the Create Point Cloud Scene Layer Package tool, complete the following steps:
- Open the Create Point Cloud Scene Layer Package geoprocessing tool.
- Specify a LAS dataset as the Input Layer.
- Specify the name of the Output Scene Package.
- Specify the Attributes to Cache.
Select all attributes that are required for the desired rendering and filtering option (for example, Intensity, returns, class codes, and RGB). To reduce storage, unused attributes should not be included. For additional information on these attributes see, What is lidar?.
- Select the Coordinate System to use.
- Optionally set the Point Size to use. The default is 0.
For airborne Lidar, accepting the default of 0 or entering a value close to the average point spacing is usually best. For terrestrial lidar data, the point size should match the desired point spacing for the areas of interest.
- Optionally set XY Max Error. The default is 0.1.
The XY Max Error is the maximum error tolerated. A higher tolerance will result in better data compression and more efficient data transfer.
- Optionally set Z Max Error. The default is 0.1.
The Z Max Error is the maximum error tolerated. A higher tolerance will result in better data compression and more efficient data transfer.
- Optionally set a Geographic Transformation.
This is the datum transformation method that will be used when the input layer's spatial reference uses a datum that differs from the output coordinate system. All transformations are bi-directional, irrespective of the direction implied by their name. For example, NAD_1927_to_WGS_1984_3 will work correctly even if the datum conversion is from WGS 1984 to NAD 1927.
