LAS Point Statistics As Raster (Data Management)

This ArcGIS 3.0 documentation has been archived and is no longer updated. Content and links may be outdated. See the latest documentation.

Summary

Creates a raster whose cell values reflect statistical information about measurements from LAS files referenced by a LAS dataset.

Usage

  • The LAS dataset layer can also be used to control the enforcement of surface constraint features that may be referenced by the LAS dataset. The constraints are enforced when displaying or processing the LAS dataset as a triangulated surface.

  • ArcGIS uses the LAS classification scheme defined by the American Society for Photogrammetry and Remote Sensing (ASPRS). Learn more about lidar point classification.

  • Consider using PREDOMINANT_LAST_RETURN for the Method parameter to identify locations with higher return values that could indicate the presence of vegetation.

  • Consider using Z_RANGE for the Method parameter to determine locations with potential outliers.

Parameters

LabelExplanationData Type
Input LAS Dataset

The LAS dataset to process.

LAS Dataset Layer
Output Raster

The location and name of the output raster. When storing a raster dataset in a geodatabase or in a folder such as an Esri Grid, do not add a file extension to the name of the raster dataset. A file extension can be provided to define the raster's format when storing it in a folder, such as .tif to generate a GeoTIFF or .img to generate an ERDAS IMAGINE format file.

If the raster is stored as a TIFF file or in a geodatabase, its raster compression type and quality can be specified using geoprocessing environment settings.

Raster Dataset
Method
(Optional)

The type of statistics collected about the LAS points in each cell of the output raster.

  • Pulse CountThe number of last return points.
  • Point CountThe number of points from all returns.
  • Most Frequent Last ReturnThe most frequent last return value.
  • Most Frequent Class CodeThe most frequent class code.
  • Range of Intensity ValuesThe range of intensity values.
  • Range of Elevation ValuesThe range of elevation values.
String
Sampling Type
(Optional)

Specifies the method that will be used for interpreting the Sampling Value parameter value to define the resolution of the output raster.

  • ObservationsThe number of cells that divide the lengthiest side of the LAS dataset extent will be used.
  • Cell SizeThe cell size of the output raster will be used. This is the default.
String
Sampling Value
(Optional)

The value used in conjunction with the Sampling Type parameter to define the resolution of the output raster.
