Summary
ArcGIS Pro supports lidar data provided as LAS or Optimized LAS (.ZLAS) files and can be used in three different formats: LAS dataset, terrain dataset, and mosaic dataset. This article provides steps to export lidar data to a CSV file in ArcGIS Pro while retaining the x, y, and z values.
Procedure
- If necessary, convert the lidar data to a LAS dataset using the Create LAS Dataset tool. Refer to Create a LAS dataset using the Create LAS Dataset geoprocessing tool for instructions.
- Convert the LAS dataset to a raster dataset using the LAS Point Statistics As Raster tool.
- Select the LAS dataset to convert for Input LAS Dataset.
- Set a name and location for Output Raster.
- In the Method drop-down list, select the desired type of statistics collected for the LAS points in each cell of the output raster. Click Run.
- Convert the raster dataset to point features using the Raster to Point tool.
- Select the output raster dataset from Step 2 for Input raster.
- Select VALUE from the Field drop-down list.
- Set a name and location for Output point features, and click Run.
- Add the x-, y-, and z-coordinate values to the attribute table of the point shapefile or feature class using the Add Geometry Attributes tool.
- Select the point shapefile or feature class as Input Features.
- In the Geometry Properties drop-down list, select Point x-, y-, z-, and m-coordinates.
- Select the proper Length Unit, Area Unit, and Coordinate System for the input features, and click Run.
- Use the Add Surface Information tool to add z values to the attribute table.
Note:
The Add Surface Information tool is only available with a 3D Analyst extension.
- Select the point shapefile or feature class as Input Features.
- Select the lidar dataset as Input Surface.
- Check the Z check box under Output Property, and click Run.
The attribute table is populated with the x, y, and z values.
- Export the attribute table to a CSV file using the Table To Table tool.
- Select the point shapefile or feature class containing the x, y, and z values for Input Rows.
- Select a folder for Output Location.
- Set a name and include the .csv extension for Output Name, and click Run.
The exported CSV file containing the x, y, and z values of the lidar data is added to the project and in the specified folder.
