Summary
In this chapter, we looked at various techniques for using OGR, GDAL, Shapely, and pyproj within Python programs to solve a range of real-world problems. In doing so, we learned how to calculate the bounding box for a country, how to use Shapely to calculate the common border between two countries, how to analyze the contents of a DEM file, how to change projections and datums, how the buffer() function can be used to find points close to a polygon, how to use pyproj to calculate the length of a geometry, and how to calculate a point a given distance and bearing from a starting point.
Up to now, we have written programs that work directly with shapefiles and other data sources to load and then process geospatial data. In the next chapter, ...
