12. Export Data - VUKOZ-OEL/3d-forest-classic GitHub Wiki

All data exported from the 3D Forest are re-transformed into their original coordinates system.

Clouds Export

The cloud data are exported via Project β†’ Export. There is an option to choose an output format (.txt, .ply or .pcd). Then the cloud for export, the name, and the location of the new file are selected.

Tree/Crown Parameters Export

All calculated tree/crown parameters as a tabular output can be exported via Trees β†’ Export tree parameters or in case of the crown via Crown β†’ Export crown parameters. The name, the location, and the separator within the exported .txt file have to be specified. The parameters that were not evaluated are exported as -1 value.

Tree Planar Projection Export

The planar projections of trees can be exported via Trees β†’ Export convex planar projection or Trees β†’ Export concave planar projection. The name and the location of the new file have to be selected. The planar projection is exported in one file for all trees. The projections that were ́t computed previously during the ongoing 3D forest session are not exported. Both functions create .txt file with coordinates of vertices of the polygon in the following format: Tree ID;Xstart;Ystart;Xend;Yend;Z Tips: the data import into ArcGIS and polygon or polyline shapefiles creation Add an exported file to your project and use function XY TO LINE in ARCTOOLBOX β†’ DATA MANAGEMENT TOOLS β†’ FEATURES. This creates a new layer containing geodetic line features constructed based on input files. To create a closed polyline from this layer use function UNSPLIT LINE in ARCTOOLBOX β†’ DATA MANAGEMENT TOOLS β†’ FEATURES. Afterward, it is possible to create polygons that are not overlapping to use function FEATURE TO POLYGON in ARCTOOLBOX β†’ DATA MANAGEMENT TOOLS β†’ FEATURES. To create overlapping polygons it is possible to use function CONVERT POLYLINES TO POLYGONS from β€žTools for Graphics and Shapesβ€œ that is freely available at http://www.jennessent.com/.

Stem Curvature Export

The stem curvature can be exported via Trees β†’ Export Stem Curvature. The dialogue window allows specifying the tree of interest, the file name, and the destination folder. The exported file is in the .txt format with the following structure:

Tree name; diameter: 70.6 67.6 64.6 ..... -1 -1 -1

Tree name; x: 182.474 182.5 182.455 ..... -1 -1 -1

Tree name; y: -1594.55 -1594.56 -1594.57 ..... -1 -1 -1

Tree name; z: 1017.6 1018.25 1018.95 ..... -1 -1 -1

Diameters and coordinates of centers of fitted circles are in ascending order of tree height, i.e. from 0.65 to 1.3, 2, etc. The value -1 indicates data that were not evaluated.

Intersections Parameters Export

The parameters of intersections can be exported via Crowns β†’ Export intersections parameters. The dialogue window facilitates to set the name of the new file and the destination folder. Parameters are exported as .txt file with the next structure: the tree name, the name of the intersecting tree, the intersection volume (m^3), the surface area of the intersection (m^2), the horizontal angle (Β°), the vertical angle (Β°), and the distance (m). The semicolon is used as a separator.
