2.5.3 Tree list import

Importing Table and Placing Trees

  1. Develop or download a tree list table using an outside data source. Ensure that the table uses the species codes and formatting described below.
  2. Set the Distribution slider to the desired position.
  3. [Optional] Determine the placement area using the Polygon Panel and the Inside/Outside controls.
  4. Click the Import Tree List button and navigate to the CSV file that you would like to import.
  5. The trees will be placed automatically after selecting the CSV file. If you would like to make a change, you can always use the Clear Last function.

 

Creating a Tree List Table

In the tree list format, each row represents a record for a cruised/modeled tree, expanded to describe a given number of trees per acre/hectare. This allows you to import tree height and other parameters that don't fit in a stand table.

 

Example

tree_id tpa vf_species dbh structure condition height sp_id sp_name cubic scribner biomass
1 1.733 PP 7 S1 Green 24 PIPO Ponderosa Pine   20  
2 1.733 PP 10 S1 Green 31 PIPO Ponderosa Pine   20  
3 1.733 PP 8 S2 Snag 24 PIPO Ponderosa Pine   20  
4 1.733 PP 11 S1 Green 39 PIPO Ponderosa Pine   20  
5 1.733 PP 9 S1 Green 38 PIPO Ponderosa Pine   20  
6 1.733 PP 7 S1 Green 25 PIPO Ponderosa Pine   20

15 1.733 SP 10 S1 Green 32 PILA Sugar Pine   80  

 

tree_id: Not used by Stand Designer, but useful for organization. 

tree_freq*: Trees per acre or trees per hectare represented by this record. Note that because the terrain is 4 acres, values that are very small (for example, less that .125 trees per acre) might never appear in the scene. If a particular tree is important, but rare on the landscape, place it manually.

vf_species*: Use pre-defined VF species codes to determine the 3D model used

dbh*: Diameter at breast height. Inches for imperial, centimeters for metric.

structure: Visual Forester structure to place the trees on (i.e. S1, S2, S3, S4)

condition: Available options are "Green", "Snag", "Stump", "Burn1", "Burn2", "Burn3". The labels are not case-sensitive.

height: Total tree height. Feet for imperial, centimeters for metric. Estimate or leave blank for inventory trees with broken top

sp_id: Display species ID used in reporting

sp_name: Display species name

cubic: Cubic volume per tree. Presumed as cubic feet for imperal, cubic meters for metric

scribner: Scribner board feet per tree. If left blank, the application will automatically estimate values representing SV616, but filling in these values yourself allows you to use other systems.

biomass: If left blank, application will automatically estimate values for dry woody biomass in stem, bark, and branches, but you can fill in your own values to represent any parameter/unit.

 

*Required values. All other fields could be left blank

Formatting Notes

To export the table for Stand Designer, follow the template above. The position of the columns MUST match the template. The column headers can use any label. When you save the table, you must save it as a .csv (comma separated values).
