Ortho Mapping from Point Cloud
In the Input Layer Type drop-down, select Point Cloud (LAS Layers).
Input Settings
Select the LAS Layer to use in the list of available layers. Only one LAS Layer can be selected.
Generate Orthophoto From
Select the attribute to generate the Orthophoto from Color (RGB) or intensity. If both are selected, two orthophotos will be generated.
Source Points
Select the Source Points from Live View needed to generate the orthophoto.�
Output Orthophoto Cell Size
Auto-Compute Cell Size
This option will compute the most effective cell size for the generated orthophoto.
Cell size
Enter the cell size manually for the orthophoto.
Estimate Cell Size
This option will calculate the recommended cell size based on the Point Density and will fill the Cell Size field.
NoteAuto Compute Cell Size estimates the density of the point cloud within the currently selected area and computes the required cell size so the most of the cells contains at least on point. Checking the Auto Compute Cell Size checkbox will produce an Orthophoto with a cell size equal to the one obtained by clicking the Estimate Cell Size button. |
Triangulation Filter
This option is used to eliminate the artifacts at the edges of the image.
Max Triangle Area
During generation of the raster file from TIN, it specifies the maximum area of the triangle to use. Any triangle that has a greater area than the specified triangle side length will be ignored.
Max Triangle Segment Length
During generation of the raster file from TIN, any side of the given triangle is greater than the specified triangle side length will be ignored.
Output Settings
Output layer Basenane
Enter the new layer name.
Area Selection
Refer to section Using a Basic Extent and Cookie-cutting by Polygons.
NoteThe option Cookie Cut into Regular Tiles is not available in Ortho Mapping |
