566: McKay sheet, west of fourth meridian, Alberta. -- 1st ed. July 1914.

This .shp file (lines) is the result of georeferencing and performing a raster to vector conversion using esri's ArcScan of Sheet 566: McKay, Alberta, 1st ed. 1st of July, 1914. 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.本数据集为基于1914年7月1日第一版阿尔伯塔省麦凯地区第566号图幅，通过Esri的ArcScan工具完成地理配准与栅格-矢量转换后生成的.shp格式线要素类文件。该图幅属于加拿大西部3英里比1英寸比例的分幅地图系列。本次矢量化作业旨在提取线要素密度指标，以测算制图完整性（Cartographic Intactness）。本研究还纳入了由加拿大内政部发布的原始地理配准扫描件与原图世界文件（world file），以供参考。
