This .shp file (lines) is the result of georeferencing and performing a raster to vector conversion using esri's ArcScan of Sheet 315: Edmonton, Alberta, 9th ed. rev. to September, 1920. This sheet is part of the 3-mile to 1-inch sectional maps of Western Canada. vectorization was undertaken to extract a measure of line work density in order to measure "Cartographic Intactness". The original georeferenced scan, and world file of the original map, published by the Department of the Interior, is included in the study for reference purposes.
