If you have vector map data sets that violate these conditions, the map display functions

geoshow, mapshow, and mapview might not be capable of rendering them as filled

polygons. To determine the directionality of polygon vertices, use the logical function

ispolycw, which returns a separate result for each NaN-delimited polygon in an

array of vertices. If you find inner rings which are clockwise or outer rings which are

counterclockwise, use the utility functions poly2ccw or poly2cw, respectively, to

reverse the direction of those rings.

Map Viewer Now Georeferences Images It Saves

When the Map Viewer saves the visible or selected area as a raster map (an image file), it

now also writes a worldfile to georeference the image.

TIGER/Line File Support Upgraded

Function tgrline now supports the most recent (2003/2004) TIGER/Line data sets from

the U.S. Bureau of the Census.
