Lineage:
Process step:
Process description:
Used 1-mile x 1-mile countywide grid to inspect the wtr_bodies feature class for missing and out-dated features, based on 2010 NAIP imagery (both CIR and color were used). Because the NAIP imagery was flown during the summer, county contours and older imagery was used to verify questionable features. Water bodies that showed up in the imagery but not in the wtr_bodies feature class were added by digitizing their boundaries. Some features in wtr_bodies no longer show up in the NAIP imagery and were deleted.
Rationale To update the feature class.
