Map of South Africa, 1892 (Raster Image)

Description:

This layer is a georeferenced raster image of an historic paper map of Southern Africa from 1892. The original map was included in Rand, McNally and Company's Indexed Atlas of the World and covers the modern day countries of South Africa, Lesotho and Swaziland, along with parts of adjacent Mozambique, Namibia, and Botswana. The original map identifies cities and towns, rivers, mountains and other topographical features, as well as historic sites, such as the diamond fields of Griqualand West. This map is part of a selection of digitally scanned and georeferenced historic maps of Africa held at Stanford University Libraries. This historic paper map provides an historical perspective of the cultural and physical landscape during this time period. The wide range of information provided on these maps make them useful in the study of historic geography. As this map has been georeferenced, it also can be used as a background layer in conjunction with other GIS data. The horizontal positional accuracy of a raster image is approximately the same as the accuracy of the published source map. The lack of a greater accuracy is largely the result of the inaccuracies with the original measurements and possible distortions in the original paper map document. There may also be errors introduced during the digitizing and georeferencing process. In most cases, however, errors in the raster image are small compared with sources of error in the original map graphic. The RMS error for this map is 708.84 meters. This value describes how consistent the transformation is between the different control points (links). The RMS error is only an assessment of the accuracy of the transformation.
