Creating the simplest possible Python GIS
Now that we have a better understanding of geospatial analysis, the next step is to build a simple GIS using Python called
SimpleGIS. This small program will be a technically complete GIS with a geographic data model and the ability to render the data as a visual thematic map showing the population of different cities.
The data model will also be structured so that you can perform basic queries. Our
SimpleGIS will contain the state of Colorado, three cities, and population counts for each city.
Most importantly, we will demonstrate the power and simplicity of Python programming by building this tiny system in pure Python. We will only use modules available in the standard Python distribution without downloading ...
