Stepping through the program
Now we're ready to work through the GPX-Reporter program. Like other scripts in this book, this program tries to minimize functions so that you can mentally trace the program better and modify it with less effort. The following list contains the major steps in the program:
Setting up the Python logging module
Establishing our helper functions
Parsing the GPX data file
Calculating the route bounding box
Buffering the bounding box
Converting the box to meters
Downloading the base map
Downloading the elevation data
Hillshading the elevation data
Increasing the hillshade contrast
Blending the hillshade and base map
Drawing the GPX track on a separate image
Blending the track image and base map
Drawing the start and finish points
Saving the map image
Calculating the route mile markers
Building the elevation profile chart
Getting the weather data for the route time period
Generating the PDF report
