Data Quality Information:
Attribute Accuracy:
Attribute Accuracy Report:
Polygon attributes were checked against legend information to ensure data was entered correctly and without omission.
Logical Consistency Report: Data are discontinuous, topologically correct polygons as built and enforced using ArcInfo software.
Completeness Report: All polygons classified as meltwater deltas and fans are contained in the dataset.
Positional Accuracy:
Horizontal Positional Accuracy:
Horizontal Positional Accuracy Report: Error associated with georeferencing is estimated to be less than +/- 250 m.
Lineage:
Process Step:
Process Description:

1. Original mylars were scanned as tiff images

2. Tiff images were geo-referenced to 1:250000 digital base in 10TM projection, NAD83 to create geo-tiffS. RMS errors were +/- 50m.

3. Geo-tiff images were vectorized and smoothed using the 'Gridline' command in Arc/Info with parameters 'Thin','Filter','Round','0.005 as Dangle' and '0.001 as Weed'. Line coverages were created.

4. Line coverages were combined to create complete polygon boundaries. Remaining linework representing linear surficial features such as channels were extracted to separate line coverages. Point features such as deltas were extracted to create a point coverage.

5. Vertices (line segments) forming polygon boundaries were snapped and un-split to create closed polygons. Sliver polygons and dangles were fixed. Labels were created for each polygon based on legend classification number.

6. Step 5 was repeated several times until all errors were fixed and each feature was properly labelled.

7. Final polygon topology was built.

8. Polygons identifed as meltwater delta/fan were extracted to a separate coverage.

9. A plot was generated at the scale of 1:500 000 to check against the original map.

10. Polygon coverage was converted to shapefile.
