Information about shapefile
returns a structure,
info = shapeinfo(
info, whose fields contain information about
the contents of a shapefile.
filename can 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,
shapeinfo returns an error. If either of the other files is
shapeinfo returns a warning.
filename— File name
File name of the shapefile, specified as a string scalar or character
filename can be the base name or the full name of
any one of the component files.
info— Information about shapefile contents
Information about shapefile contents, returned as a structure contains the following fields.
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
The number of spatial features in the shapefile
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.
