The trackname.csv file contains stratification codes that describe the origin characteristics of each track. Track name records are not required and it is not an error to omit them. If specified, they are used by some of the reporting tools to help identify the origin of the forest type in terms of the original stratification variables.

Table 7. Trackname file format

AttributeData TypeDescription
TRACKStringAn alphanumeric label that matches a track label from the block file (see the section called “Blocks”). It is an error to include track names for non-existent tracks.
STRATAStringA string describing the original inventory stratification that contributes to the track.

The content of the STRATA is arbitrary, but the values produced by the Matrix builder use the following convention:

Consider the following example records:

    Track.3,1.0 x 0+MU(RMF)+FU(SB1)+SI(Basc1)
    Track.4,0.6 x 0+MU(RMF)+FU(SB1)+SI(Basc1) +  0.4 x 3+MU(RMF)+FU(SB1)+SI(Basc1)

The above example shows that Track.3 originated from an inventory unit that had stratification values where the MU code is RMF, the FU code is SB2, and the SI code is Basc1. 100% of the area is has the same stratification codes with the same initial age offset.

Track.4 is composed of two parts, both having the same stratification codes. The first part is the dominant proportion and makes up 60% of the area. The second part makes up 40% of the area, and is 3 years older than the first part.


The proportional amounts for all strata descriptor components must sum to 1.0.
