Add Files to LAS Dataset
Adds references for one
or more LAS files and surface constraint features to a LAS dataset.
1. Input LAS Dataset
The LAS dataset to
process.
2. LAS Files or Folders (optional)
Input files can
reference any combination of individual LAS files and folders containing LAS
data.
In the tool dialog
window, a folder can also be specified as an input by selecting the desired
folder in Windows Explorer and dragging it into the parameter's input box.
3. Include Subfolders (optional)
Specifies whether LAS files residing in the subdirectories of an input folder will be referenced by the LAS dataset.
- Unchecked—Only LAS files found in an input folder will be added to the LAS dataset. This is the default.
- Checked—All LAS files residing in the subdirectories of an input folder will be added to the LAS dataset.
4. Surface Constraints (optional)
The features that will contribute to the definition of the triangulated surface generated from the LAS dataset.
- Input Features—The features whose geometry will be incorporated into the LAS dataset's triangulated surface.
- Height Field—The feature's elevation source can be derived from any numeric field in the feature's attribute table or the geometry by selecting Shape.Z. If no height is desired, specify the keyword <None> to create Z-less features whose elevation would be interpolated from the surface.
- Type—Defines the feature's role in the triangulated surface generated from the LAS dataset. Options with hard or soft designation refer to whether the feature edges represent distinct breaks in slope or a gradual change.
- Surface Feature Type—The surface feature type that defines how the feature geometry gets incorporated into the triangulation for the surface. Options with hard or soft designation refer to whether the feature edges represent distinct breaks in slope or a gradual change.
- hardline or softline—Breaklines that enforce a height value.
- hardclip or softclip—Polygon dataset that defines the boundary of the LAS dataset.
- harderase or softerase—Polygon dataset that defines holes in the LAS dataset.
- hardreplace or softreplace—Polygon dataset that defines areas of constant height.

Create LAS Dataset
Creates a LAS dataset
referencing one or more LAS files and optional surface constraint features.
1. Input Files
The LAS files and
folders containing LAS files that will be referenced by the LAS dataset.
In the tool dialog
window, a folder can also be specified as an input by selecting the desired
folder in Windows Explorer and dragging it into the parameter's input box.
2. Include Subfolders (optional)
Specifies whether LAS files residing in the subdirectories of an input folder will be referenced by the LAS dataset.
- Unchecked—Only LAS files found in an input folder will be added to the LAS dataset. This is the default.
- Checked—All LAS files residing in the subdirectories of an input folder will be added to the LAS dataset.
3. Output LAS Dataset
The LAS dataset that
will be created.
4. Surface Constraints (optional)
The features that will contribute to the definition of the triangulated surface generated from the LAS dataset.
- Input Features—The features whose geometry will be incorporated into the LAS dataset's triangulated surface.
- Height Field—The feature's elevation source can be derived from any numeric field in the feature's attribute table or the geometry by selecting Shape.Z. If no height is desired, specify the keyword <None> to create Z-less features whose elevation would be interpolated from the surface.
- Type—Defines the feature's role in the triangulated surface generated from the LAS dataset. Options with hard or soft designation refer to whether the feature edges represent distinct breaks in slope or a gradual change.
- Surface Feature Type—The surface feature type that defines how the feature geometry gets incorporated into the triangulation for the surface. Options with hard or soft designation refer to whether the feature edges represent distinct breaks in slope or a gradual change.
- anchorpoints—Elevation points that never get thinned away. This option is only available for single-point feature geometry.
- hardline or softline—Breaklines that enforce a height value.
- hardclip or softclip—Polygon dataset that defines the boundary of the LAS dataset.
- harderase or softerase—Polygon dataset that defines holes in the LAS dataset.
- hardreplace or softreplace—Polygon dataset that defines areas of constant height.
5. Coordinate System (optional)
The spatial reference of
the LAS dataset. If no spatial reference is explicitly assigned, the LAS
dataset will use the coordinate system of the first input LAS file. If the
input files do not contain any spatial reference information and the Input
Coordinate System is not set,
then the LAS dataset's coordinate system will be
listed as unknown.
6. Create PRJ For LAS Files (optional)
Specifies whether .prj files will be created for the LAS files referenced by the LAS dataset.
- NO_FILES—No files will have a PRJ file created. This is the default.
- FILES_MISSING_PROJECTION—Only LAS files without a spatial reference will have a corresponding PRJ file.
- ALL_FILES—All LAS files will have a corresponding PRJ file.
7. Compute Statistics (optional)
Specifies whether statistics for the LAS files will be computed and a spatial index generated for the LAS dataset. The presence of statistics allows the LAS dataset layer's filtering and symbology options to only show LAS attribute values that exist in the LAS files. A .lasx auxiliary file is created for each LAS file.
- Unchecked—Statistics will not be computed. This is the default.
- Checked—Statistics will be computed.
8. Store Relative Paths (optional)
Specifies whether lidar files and surface constraint features will be referenced by the LAS dataset through relative or absolute paths. Using relative paths may be convenient for cases where the LAS dataset and its associated data will be relocated in the file system using the same relative location to one another.
- Unchecked—Absolute paths will be used for the data referenced by the LAS dataset. This is the default.
- Checked—Relative paths will be used for the data referenced by the LAS dataset.
