Label | Explanation | Data Type |
Input LAS Dataset | The LAS dataset that will be processed. Only the last return of LAS points with class code values of 0, 1, and 2 will be evaluated. | LAS Dataset Layer |
Ground Detection Method | Specifies the method that will be used to detect ground points.
| String |
Reuse existing ground (Optional) | Specifies whether existing ground points will be reclassified or reused.
| Boolean |
DEM Resolution (Optional) | A distance that will result in only a subset of points being evaluated for classification as ground, making the process faster. Consider using this parameter when a faster method for generating a DEM surface is needed. The minimum distance is 0.3 meters, but the provided distance must be at least 1.5 times the average point spacing of the lidar data for this process to take effect. | Linear Unit |
Compute statistics (Optional) | Specifies whether statistics will be computed for the .las files referenced by the LAS dataset. Computing statistics provides a spatial index for each .las file, which improves analysis and display performance. Statistics also enhance the filtering and symbology experience by limiting the display of LAS attributes, such as classification codes and return information, to values that are present in the .las file.
| Boolean |
Processing Extent (Optional) | The extent of the data that will be evaluated.
| Extent |
Processing Boundary | A polygon feature that will define the area of interest to be processed. | Feature Layer |
Process entire LAS files that intersect extent
(Optional) | Specifies how the area of interest will be used in determining how .las files will be processed. The area of interest is defined by the Processing Extent parameter value, the Processing Boundary parameter value, or a combination of both.
| Boolean |
Update pyramid
(Optional) | Specifies whether the LAS dataset pyramid will be updated after the class codes are modified.
| Boolean |
Detection Algorithm (Optional) | Specifies the version of the ground detection algorithm that will be used to classify the ground points.
| String |
Classify low-noise points
(Optional) | Specifies whether points below a given distance beneath the ground will be classified as low noise. The distance at which noise points are identified is based on the Minimum Depth Below Ground parameter value. Low-noise points are assigned a class code value of 7.
| Boolean |
Minimum Depth Below Ground
(Optional) | The distance below the ground that will be used to classify low-noise points. The ground will be defined by a triangulated surface created from ground-classified points. All points with class codes 0 or 1 that are below the ground by the height provided in this parameter will be assigned a class code value of 7. | Linear Unit |
Preserve existing low noise
(Optional) |
Specifies whether existing low-noise points with class code 7 will be preserved or reclassified. If low-noise points are reclassified, any points that are not below the ground by at least the distance provided for the Minimum Depth Below Ground parameter value will be assigned a class code value of 1.
| Boolean |
Classify high-noise points
(Optional) | Specifies whether points above a given distance from the ground will be classified as high noise. The distance at which noise points are identified is based on the Minimum Height Above Ground parameter value. High-noise points are assigned a class code value of 18.
| Boolean |
Minimum Height Above Ground
(Optional) | The distance above the ground that will be used to classify high-noise points. The ground will be defined by a triangulated surface created from ground-classified points. All points with class codes 0 or 1 that are above the ground by the height provided in this parameter will be assigned a class code value of 18. | Linear Unit |
Preserve existing high noise
(Optional) |
Specifies whether existing high-noise points with class code 18 will be preserved or reclassified. If high-noise points are reclassified, any points that are not above the ground by at least the distance provided for the Minimum Depth Above Ground parameter will be assigned a class code value of 1.
