  <abstract lang="eng" displayLabel="Abstract">This layer is a georeferenced raster image of a map of the United States, Canada, Mexico, Central America, and the West India Islands, with portions of Venezuela and Granada. The original map was created and published by J.M. Atwood in 1851. The map shows the Gold Regions of California as well as routes over land and by Isthmus to California and Oregon. All map collar and inset information is also available as part of the raster image, including any inset maps, profiles, statistical tables, directories, text, illustrations, or other information associated with the principal map. A scanned veriosn of this map was georeferenced by the Center for Spatial and Textual Analysis (CESTA) at Stanford University. This map is part of a selection of georeferenced historic maps from the David Rumsey Map Collection at Stanford University.</abstract>
  <abstract lang="eng" displayLabel="Purpose">This layer 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.</abstract>
  <note lang="eng" displayLabel="Attribute accuracy report">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 221.645 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.</note>

  <note displayLabel="Supplemental information">The David Rumsey Map Collection contains more than 150,000 maps. The collection focuses on rare 18th and 19th century maps of North and South America, although it also has maps of the World, Asia, Africa, Europe, and Oceania. The collection includes atlases, wall maps, globes, school geographies, pocket maps, books of exploration, maritime charts, and a variety of cartographic materials including pocket, wall, children's, and manuscript maps. Items range in date from about 1700 to 1950s. More information: https://purl.stanford.edu/xh235dd9059.</note>
