MORPS - Modifying Objects to Reduce Python Scripting

Python should be simple. Writing ~50 lines of code to create one buffer is not simple.

Morps attempts to simplify geoprocessing with Python. Using the terminal/command line interface, navigate to the directory storing the morps.py file.

Type

python

to start the python shell and begin using morps

import morps

cities = "data/cities.shp"
cities_buffered = "data/cities_buffered.shp"
unit = 'miles'
format = 'shp'

morps.buffer(cities,cities_buffered,500,unit,format)

or even simpler

morps.buffer("data/cities.shp","data/cities_buffered.shp",500,"miles","shp")

Installation

Note: This library is built on top of GDAL, and is required to be installed in order for MORPS to work correctly. Find GDAL install instructions here. If you do not get errors when typing import ogr into the Python shell, you know that Python is configured and you are ready to use morps.

To install Morps, clone this repository or download the latest build from the Python Package Index. Unzip the file and open the terminal (or Windows Command Shell) and cd into the directory. Type the following command to install:

python setup.py install

If it installs with no errors, start the Python shell and attempt to import morps

import morps

All right, lets Merk some Morps!

Geoprocessing Supported by Morps:

  • Buffer
  • Contains
  • Difference
  • Disjoint
  • Distance
  • Equals
  • Find Centroid
  • Feature Count
  • Get Feature Envelope
  • Get Fields
  • Get Layer Extent
  • Get Unique Values
  • Intersect
  • Simplify
  • Symmetric Difference
  • Within

The code in this repo is also intended to demonstrate how one could utilize the OGR vector library within GDAL for performing basic geoprocessing tasks.
