LAS Height Metrics

Calculates statistics about the distribution of elevation measurements of vegetation points captured in LAS data.

1.    Input LAS Dataset

The LAS dataset to process.

2.    Output Location

The folder or geodatabase where the output raster datasets will reside. When the output location is a folder, the resulting raster datasets will be in the TIFF format.

3.    Output Base Name (optional)

The base name for the output raster datasets.

4.    Height Percentiles (optional)

The height at which the specified percentage of points in the cell fall below. For example, a value of 95 means the resulting cell values indicate the height at which 95 percent of points above the ground occur.

5.    Minimum Height (optional)

The minimum height above ground for points that will be evaluated.

6.    Minimum Number Of Points (optional)

The minimum number of points that must be present in a given cell to calculate height metrics. Cells with fewer points than the specified minimum will have no data in the output.

7.    Cell Size (optional)

The cell size of the output raster datasets.

LAS Point Statistics By Area

Evaluates the statistics of LAS points that overlay the area defined by polygon features.Input LAS Dataset The LAS dataset to process.Input Polygons The polygon that defines the area for which statistics will be reported.

1.    Input LAS Dataset

The LAS dataset to process.

Output Property (optional)

The properties that will be calculated.

·      Z_MIN—The lowest Z value of LAS points overlapping the feature.

·      Z_MAX—The highest Z value of LAS points overlapping the feature.

·      Z_MEAN—The average Z value of LAS points overlapping the feature.

·      POINT_COUNT—The tally of LAS points that were evaluated.

·      STANDARD_DEVIATION—The standard deviation of Z values.

2.    Input Polygons

The polygon that defines the area for which statistics will be reported.

 3.    Output Property (optional)

The properties that will be calculated.

· Z_MIN—The lowest Z value of LAS points overlapping the feature.

· Z_MAX—The highest Z value of LAS points overlapping the feature.

· Z_MEAN—The average Z value of LAS points overlapping the feature.

· POINT_COUNT—The tally of LAS points that were evaluated.

· STANDARD_DEVIATION—The standard deviation of Z values.

Locate LAS Points By Proximity

How to use Locate LAS Points By Proximity Tool in Arc Toolbox ArcMap ArcGIS ??

Locate LAS Points By Proximity

Locate LAS Points By Proximity Tool, LAS Dataset Toolset, Data Management Toolset, 3D Analyst Toolbox

 

Locate LAS Points By Proximity

Identifies LAS points within the three-dimensional proximity of z-enabled features along with the option to reclassify those points. Input LAS Dataset The LAS dataset to process.Input 3D Features The 3D point, line, polygon, or multipatch features whose proximity will be used for identifying LAS points.

1.    Input LAS Dataset

The LAS dataset to process.

2.    Input 3D Features

The 3D point, line, polygon, or multipatch features whose proximity will be used for identifying LAS points.

3.    Search Radius (optional)

The distance around the input features that will be evaluated for the presence of LAS points, which can be provided as either a linear distance or a numeric field in the input feature's attribute table. If the search radius is derived from a field or a linear distance whose units are specified as Unknown, the linear unit of the input features' XY spatial reference is used.

4.    Count Field (optional)

The name of the field that will be added to the input feature's attribute table and populated with the number of LAS points in each feature's proximity. The default field name is COUNT.

5.    Output Feature Class (optional)

The point features that represent the LAS points detected within the specified proximity of the input features.

6.    Output Geometry Type (optional)

Specifies the geometry of the output point features that represent the LAS points found within the specified proximity of the input features.

· MULTIPOINT—Multipoint features that will have multiple points in each row.

· POINT—Single-point features that will have a unique row for each identified LAS point.

Specifies the geometry of the output point features that represent the LAS points found within the specified proximity of the input features.

· MULTIPOINT—Multipoint features that will have multiple points in each row.

POINT—Single-point features that will have a unique row for each identified LAS point. The name of the field that will be added to the input feature’s attribute table and populated with the number of LAS points in each feature’s proximity. The default field name is COUNT.Output Feature Class (optional)

7.    New Class Code (optional)

The class code value that will be used to reclassify the points found within the search radius of the input features.

 8.    Compute Statistics (optional)

Specifies whether statistics should 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, like classification codes and return information, to values that are present in the LAS file.

· Checked—Statistics will be computed.

· Unchecked—Statistics will not be computed. This is the default
