ATTRIBUTE INFORMATION =====================================================================- == System Software: Arc/Info Table Name:.PAT ============================================ Item Name: tim_type Item Type: char Item Length: 6 Item Value Description Variable length field composed of primary species, secondary species (if present), conifer size class, conifer density (crown cover). Note that size class & density apply ONLY to the commercial conifer component. Thus, heavily stocked polygons could conceivably be classified as poor or sparse (density) if the stocking were mainly in hardwoods and/or non-commercial conifers. examples: DFWF3G DF3G BA/N LQ/T M.89 Timber Type labels have been decomposed (parsed) into the following items: Item Name: s1 and s2 Item Type: char Item Length: 2 Primary (s1) and secondary (s2) species Item Value Description I.
