Where did the Mapping Toolbox "Atlas Data" MAT-files go in MATLAB 7.0.4 (R14SP2)?

14 views (last 30 days)
I cannot locate any of the following Mapping Toolbox MAT-files when running Version 2.1 (R14SP2): worldlo, worldhi, worldmtx, worldmtxmed, usalo, and usahi.
For example, when I use WHICH to locate worldlo.mat I receive the following error:
which worldlo.mat
'worldlo.mat' not found.

World geopolitical data is difficult to maintain in a timely and authoritative way, and therefore, except for national and state boundaries for the U.S.A., Mapping Toolbox 2.1 for MATLAB 7.0.4 (R14SP2) does not ship with geopolitical boundary data ("Atlas Data"), as in previous releases.
World coastlines, lakes, rivers, and city locations are provided as demo data, preserving some of the contents of the worldhi, worldmtx, worldmtxmed, usalo, and usahi MAT-files as shapefiles in the map/mapdemos directory:
Vector data for the world in shapefile format:
LANDAREAS.SHP -- Medium-resolution outlines of land masses and major islands
WORLDLAKE.SHP -- Medium-resolution outlines of bodies of water across the world
WORLDRIVERS.SHP -- Medium-resolution traces of major rivers
WORLDCITIES.SHP -- Major world city names and point locations
Vector data for the United States:
USASTATELO.SHP -- Contents of usalo.mat in shapefile format
USASTATEHI.SHP -- Contents of usahi.mat in shapefile format
CONUS.MAT -- Polygon outlines of the conterminous United States and the Great Lakes, and state boundary lines, stored in coordinate arrays
GREATLAKES.MAT -- Three polygons representing the five US-Canadian Great Lakes stored as a geostruct 1
Several other geodata files are provided for demos and code examples. When making maps, you can either read geopolitical data already in your possession into the Mapping Toolbox, obtain it from third parties, or use the demo data provided with the Mapping Toolbox.
See the following Tech Note for more information on accessing geospatial data, including many publicly available Internet resources.
Accessing Geospatial Data on the Internet for the Mapping Toolbox.
For information on these and other updates to the Mapping Toolbox, refer to the Mapping Toolbox 2.1 Release Notes, and to the Mapping Toolbox documentation.
