It is not necessary to include the file extension (.shp) on the end of <code><i>shapefile</i></code>, just the filename root is adequate.<br> <codoe> <br> <h3>Usage Notes</h3> <p>This command is available with GrADS version 2.0.a8 or later.</p> <p> If you put the three shapefile components (*.shp, *.shx, and *.dbf) in the GrADS data directory (pointed to by the <a href="gradcomdgrads.html#env">GADDIR environment variable</a>), then it is not necessary to include the full path in <code><i>shapefile</i></code>. </p> <p>The first line of output contains the shapefile type, the number of shapes in the file, and the X and Y bounds of actual extent of the shapes in the file. Subsequent lines list information about each shape element in the file: the identification number, the shape type, the number of parts, the number of vertices, and the bounds of the shape in the X, Y, Z, and M (measure) dimesions. The current GrADS interface ignores the Z or M values of a shape, only it's position in X,Y (lon,lat) space is relevant. </p> <p>A companion command, <code><a href="gradcomdqdbf.html">q dbf</a></code>, lists the attribute database entries for each element in the shapefile. There is a 1:1 correspondence between elements in the shapefile and records in the database. </p> <p>Please see the documentation page on <a href="shapefiles.html">shapefiles</a> for more details. </p> <p> </p> <h3>Examples </h3> <pre>ga-> q shp /home/GIS/climatedivs/divisions<br> Shapefile Type=Polygon #Shapes=387 XBounds=-124.761:-66.95 YBounds=24.545:49.385 0: Polygon parts=1 vertices=51 XBounds=-95.602:-93.056 YBounds=46.285:49.385 ZBounds=0:0 MBounds=0:0 1: Polygon parts=1 vertices=88 XBounds=-123.081:-121.919 YBounds=46.621:49.002 ZBounds=0:0 MBounds=0:0 2: Polygon parts=1 vertices=135 XBounds=-123.773:-121.207 YBounds=45.548:49.002 ZBounds=0:0 MBounds=0:0 3: Polygon parts=1 vertices=91 XBounds=-121.611:-119.484 YBounds=45.681:49.001 ZBounds=0:0 MBounds=0:0 4: Polygon parts=1 vertices=36 XBounds=-120.46:-117.558 YBounds=47.149:49.001 ZBounds=0:0 MBounds=0:0 5: Polygon parts=1 vertices=25 XBounds=-117.041:-116.048 YBounds=47.006:49.001 ZBounds=0:0 MBounds=0:0 . . . 385: Polygon parts=1 vertices=46 XBounds=-122.513:-121.659 YBounds=43.551:45.647 ZBounds=0:0 MBounds=0:0 386: Polygon parts=1 vertices=67 XBounds=-121.946:-118.222 YBounds=44.771:46.001 ZBounds=0:0 MBounds=0:0 </pre> </body> </html>
