Computing bounding box for a list of coordinates in Python

23. February 201725. February 2017 Uli Köhler Geoinformatics, Python

Problem:

You have a list of X/Y coordinates, for example:

coords = [(6.74219, -53.57835),
          (6.74952, -53.57241),
          (6.75652, -53.56289),
          (6.74756, -53.56598),
          (6.73462, -53.57518)]

For these coordinates you want to compute the minimum bounding box.

Reading a Shapefile directly from a ZIP using pyshp

Problem

You have a ZIP file containing a single ESRI shapefile database (i.e. three files), for example the Natural Earth Countries database. Without unzipping the ZIP you want to use pyshp in order to read the data contain in the shapefile.
