Yield Table Generator
YTGen is software for generating yield estimates in a production forestry context. It combines the process of growing and projecting tree volumes with log bucking alogorithms to model tree merchandising through to log products.
YTGen provides the function for generating yields by taking a sample forest inventory, applying height and DBH Regression to the sample, projecting volume and taper and estimating breakage and stumpage.
YTGEN is owned and licensed by Silmetra Limited, who jointly with Interpine provide training courses and is actively used by Interpine.
Key Design Philosophies
- Do a few things well: grow trees, cut them up and add them up.
- Separate yield generation from inventory data collection.
- Separate yield generation from decision support.
- Integrate well with upstream and downstream processes.
Data Inputs and Outputs
YTGEN prepares data from a number of common sources (such as MARVL) and converts it to a YTGEN Population File. Combined with cutting strategies and a method reference file (models), these produce outputs from basic population yields through to detailed log output.
There are customised output formats for decisions support tools like FOPLI and Woodstock.
YTGEN currently runs on Windows 95 through to Windows 8 with independent applications also provided.
