Working with Geospatial (SHP) Data in Linux
Node.js Python To manipulate shape files in Python 2.x, you’ll need the pyshp package. These Required Libraries instructions will quickly outline how to install and use this package to get GIS data out of *.shp files. node-shp: Github - https://github.com/yuletide/node-shp Installation npm - https://npmjs.org/package/shp To install pyshp you first must have setuptools installed in your python site- packages. (To install setuptools on Windows, follow these instructions: http:// Installation stackoverflow.com/a/309783) $ npm install shp Ubuntu/Debian
$ sudo apt-get install python-setuptools Usage (Simple Example) Once you’ve installed setuptools, easy_install the improved python package var Shp = require('shp'); manager, pip. You’ll want to use pip to install any of the additional libraries Shp.readFile('path/to/shpfile_base_name', function (error, data){ your project requires: console.log(JSON.stringify(data)); $ easy_install pip }); Lastly, pip install the pyshp library:
$ pip install pyshp Using pyshp
Now that the pyshp library is installed, you can use it in your python project: >>> import shapefile >>> file = shapefile.Read(‘filename.shp’) >>> shapes = file.shapes() # list of shape objects >>> shape1_coords = shapes[0].points # list of coor- dinate tuples
Further instructions can be found in the official documentation for pyshp: http://code.google.com/p/pyshp/wiki/PyShpDocs PARTICIPANT’S GUIDE

Install Geo::ShapeFile ($ sudo cpanm Geo::ShapeFile) Usage (Simple Example) 4. Follow this example: (rename Arenas to the name of the .shp file you’re working with. The .shp files must be in the same directory as your .pl file) false); //sets the options to show the polygon points, 'noparts' => true would skip that and save time Usage (Simple Example) //Create Shape object use Geo::ShapeFile; $shp = new ShapeFile("filename.shp",$options); my $shapefile = new Geo::ShapeFile("Arenas"); //Dump the ten first records $i = 0; for(1 .. $shapefile->shapes()) { while ($record = $shp->getNext() and $i<10) { my $shape = $shapefile->get_shp_record($_); $dbf_data = $record->getDbfData(); # see Geo::ShapeFile::Shape docs for what to do $shp_data = $record->getShpData(); with $shape //Dump the information my %db = $shapefile->get_dbf_record($_); var_dump($dbf_data); } var_dump($shp_data); $i++; } ?>
