All polygons are closed and lines intersect where intended.
Region feature classes were created for the three levels of ECS classes, Province, Section and Subsection. Completeness All ECS boundaries in the state were re-located based on the definition of the Land Type Association boundaries, the fourth step in the ECS classification process. Significant differences exist between the older version of the ECS data. LTA's were delineated by manually interpreting a variety of land surface information including topography, wetland distributions, soil characteristics, Hydrography, presettlement vegetation, bedrock type, Landsat satellite imagery, geomorphology and local knowledge of the landscape from individuals on each landscape team. The interrelationship of features were examined by overlaying thematic maps and observing coincident patterns.
