Equidistant Cylindrical Projection Maps of the Eclipse Path
6 through 19 all use a simple equidistant cylindrical projection scaled for the central
latitude of each map. They all use high resolution coastline data from the World Data Base II (WDB) and
World Vector Shoreline (WVS) data bases and have a scale of 1:2,784,000. These maps were chosen to
isolate small regions along the entire land portion of the eclipse path. Once again, curves of maximum eclipse
and constant eclipse magnitude are included as well as the outline of the umbral shadow. A special feature
of these maps are the curves of constant umbral eclipse duration (i.e., totality) which are plotted within
the path. These curves permit fast determination of approximate durations without consulting any tables.
Furthermore, city data from a recently enlarged geographic data base of over 90,000 positions are plotted to
give as many locations as possible in the path of totality. Local circumstances have been calculated for
these positions and can be found in Tables 9 through 35.
