Try ogrinfo, i.e.

$ ogrinfo -al ./shapefile.shp

The first bit of information returned provides an overview of the data
(extent, field definitions, geometry type), then followed by a
feature-by-feature report.

Subject: [Mapserver-users] Full extent of the shape file


I have the shape file, which metadata says to have the extent of 
Spatial_Domain: 
  Bounding_Coordinates: 
    West_Bounding_Coordinate: -122.5 
    East_Bounding_Coordinate: -121.1 
    North_Bounding_Coordinate: 47.8 
    South_Bounding_Coordinate: 47.1 
Mapserver however identifies the following boundary (when requested via
GetCapabilities WMS request)
    <Layer queryable="0" opaque="0" cascaded="0">
        <Name>king_cou</Name>
        <Title>King County, WA</Title>
        <SRS>EPSG:2855</SRS>
        <LatLonBoundingBox minx="-111.388" miny="46.3886"
maxx="-106.113" maxy="49.1724" />
        <BoundingBox SRS="EPSG:2855"
                    minx="1.21826e+006" miny="30932.7"
maxx="1.57787e+006" maxy="287704" />
    </Layer>
The LatLonBoundingBox is completely different than the real boundary
defined by the meta info. Mapserver actually returns the image if
requested with an extent within "it's own" boundary but return only
blank if boundary is outside of that, but within the metainfo boundary.
Any thoughts? What tool can I use to check the full extent of a shape
file.
Why does Mapserver reads wrong full extent?
Any help would be greatly appreciated.
Thanks
