DATA FILES

\Data\Umatilla_GLO_pts.shp: ESRI ArcGIS shapefile (and associated files) containing General Land Office (GLO) survey point locations.
Variables include:
FID = internal feature number, which contains sequential unique whole numbers that are automatically generated
Shape = feature geometry (point)
IDTRSD = join field of township, range, and section number


\Data\corner_trees.dbf and \Data\corner_trees.csv: dBase database file (DBF) and comma-delimited ASCII text file (CSV) containing tree species, diameter, and distance to survey points at section corners and quarter corners (i.e., middle of section lines). See Powell (2008) for more details.
Variables include:
OID = internal feature number
IDTRSD = join field of township, range, and section number
TreeSpecie = tree species (see \Data\tree_species.csv for a list of the tree species and the associated scientific name)
TreeDia = tree diameter at breast height (inches)
TreeDist = distance to a corner in links (a link is one-hundredth of a chain and since a chain is 66 feet, then one link is 0.66 feet)


\Data\line_trees.dbf and \Data\line_trees.csv: dBase database file (DBF) and comma-delimited ASCII text file (CSV) containing tree species and diameter for trees measured along survey lines. See Powell (2008) for more details.
Variables include:
OID = internal feature number
IDTRSD = join field of township, range, and section number
TreeSpecie = tree species (see \Data\tree_species.csv for a list of the tree species and the associated scientific name)
TreeDBH = tree diameter at breast height (inches)


\Data\tree_species.csv: Comma-delimited ASCII text file containing a list of the tree species and corresponding scientific names found in corner_trees and line_trees data files.
Variables include:
DataFile = name of data file that referenced species
TreeSpecies = tree species as referenced in data file
CommonName = common name for tree species
ScientificName = scientific name for tree species
