Abstract:
This is a digital version of two USGS maps titled Miscellaneous Geologic Investigations (West) I-357 and Miscellaneous Geological Investigations (East) I-357 in association with the work of Karlstrom et. al. ,1964. This coverage depicts the linear moraine features only.
Purpose: Provide appropriate scale data to meet park management needs.
Supplemental_Information:
The original source maps at a scale ratio of 1:1,584,000 were used to transfer the color coded polygons to Mylar oversheets by tracing with rapidiograph pens. The overlays were scanned and vertorized using software, then georeferenced and cleaned. Attributes were then coded. Since the arcs depicting linear moraine features would have intersected the deposit type polygons, they were scanned and processed separately from the surfgeol coverage. This arc feature coverage was the result.

Contractor scanned, georeferenced, attributed geology maps. NPS managed contract, QC'd product, and processed the coverage for placement in permanent data set.
Process_Step:
Process_Description:
Contractor Greenhorne & O'Mara, Inc used USGS maps to produce ArcInfo coverage for NPS using following process: Mylar sheets were overlain on the hard-copy geologic survey maps. Corner tics were etched on the mylar overlays with a rapidiograph pen. Utilizing a light table, the Qcode extents, indicated by the colored polygons on the hard-copy maps, were traced onto the mylar overlays with rapidiograph pens. Intersecting latitude/longitude tics were indicated and labeled for reference. The resultant inked mylar overlays were scanned and output into TIF format Utilizing the SRV software package, the linework was autovectorized. After vectorization, the linework was imported and the file was attributed. The coverages provided by NPS contained tics that represented real world coordinate values. The new coverages were transformed into the provided coverages. The project specification dictated that the NPS provided coverages supercede the older data set in cases of conflict (e.g., differing coastline features.) "Qcode" attributes were assigned; utilizing the ARC/INFO software package QC Plots were created for each individual map. Visual quality assurance was conducted by overlaying each plot on the corresponding geologic maps. The separate coverages were edgematched and dissolved into one coverage. NPS received interim checkplots and digital data for internal QC. Final edit were performed at contractor facility. Final digital quality assurance was conducted., Report was finalized and product was produced on CDRom for final delivery to NPS.
