Information about shapefile
info = shapeinfo(filename)
info = shapeinfo(filename) returns
info, whose fields contain information
about the contents of a shapefile.
be the base name or the full name of any one of the component files.
shapeinfo reads all three files as long as they
exist in the same folder and the unit of length or angle is not specified.
If the main file (with extension
.SHP) is missing,
an error. If either of the other files is missing,
info structure contains the following
Char array containing the names of the files that were read
Character vector containing the shape type
Numerical array of size 2-by-N that specifies the minimum (row 1) and maximum (row 2) values for each dimension of the spatial data in the shapefile
Structure array of size 1-by-
The number of spatial features in the shapefile
Attributes structure contains these fields:
|Character vector containing the attribute name as given in the xBASE table|
|Character vector specifying the MATLAB® class of the attribute
data returned by |
shapeinfo cannot tell you which coordinate
system the data in a shapefile uses. Coordinates can be either planar
(x, y) or geographic (lat, lon)
and have a variety of units. This information can be critical to the
proper display of shapefile vector data. For more information on this
topic, see Mapstructs and Geostructs.
