Attribute_Accuracy_Report:
Attributes were tested against know values as compiled on the 1:62500 qaudrangles by The Vermont Geological Survey.
Logical_Consistency_Report:
The mapping of surficial geologic features was performed from 1956 thru 1970 by various geologists utilizing field survey methods (see the Data_Set_Credit section for complete citation). Field mapping varied by 15 minute quadrangle. The mapped quadrangles were then compiled for the 1970 Surficial Geologic Map of Vermont. Within the extent of the St. Albans 15 minute quad, compilation of surficial geologic features was not completed. This resulted in a large area attributed with a feature_type equal to "No Data". Edge matching and inconsistancies in adjoing geologic units on the 15 minute quads were resolved by referring to the 1:250000 scale 1970 Surficial Geologic Map of Vermont. Edgematching was not done by geologic compiling methods, but rather by connecting similar geologic units for a best cartographic fit.

Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The positional accuracy of each feature is based on the original compilation as performed by the geologist in the field. The data was compiled by mapping on the ground using standard geologic pace and compass techniques. Field results were recorded on paper copies of 15-minute series USGS quadrangles. The accuracy of the digitized features was tested by sampling twenty random features from each feature class and comparing them to their representation on the scanned, georectified 1:62500 source quadrangles. All sample features tested within 5 meters of their representative raster feature.

Process_Description:
Georectification of scanned 15-minute quadrangles. USGS topographic maps were individually georectified to Vermont State Plane (NAD 83/Meters) coordinates using the ESRI georeferencing utility. 6 to 8 control points – defined as coordinate ticks – on each map were matched to their VT State Plane locations by aligning the four corner points to their State Plane coordinates. A WGS decimal degree grid was used for alignment. In some cases partial maps were aligned using two corner points and two points along the map edge. A first order polynomial (affine) transformation with nearest-neighbor resampling was used to finalize the map data into GeoTiff format once a satisfactory alignment was achieved (maximum RMSE of 1.5).

Process_Description:
Digitization of paper 15-minute quadrangles. Five categories of features were digitized from the raster format maps: Quarries (point features), Striations, Rock Outcrops, Till Fabric (line features) and Contacts (polygon features). Complex features such as lines and polygons were digitized using advanced raster-to-vector conversion techniques available with the ESRI ArcScan extension. Maps were reclassified into binary form to isolate hand-drawn lines, which were then detected and digitized using an array of vector trace tools. Contact features were overlain on the coarse-resolution 1970 1970 Surficial Geologic Map of Vermont and examined for inconsistencies. Labels from the 1970 map were considered the default in locations of conflicting Contact type. Resulting features were cross-checked by at least one additional analyst, then reviewed directly by the office of the state geologist. Once they were revised and approved, features were merged into those of adjacent maps, and spatial displacement errors at map edges were manually corrected. As mentioned before edgematching was not performed as geologic compilation, but instead to satisfy cartographic fit. Topology rules were employed for polygon features to ensure that the finalized map did not contain feature gaps or overlaps.
