The initial setup

The beginning of the program is to import statements followed by the Python logging module. The logging module provides a more robust way to track and log the program status than simple print statements. In this part of the program, we configure it as follows:

from xml.dom import minidom
import json
import urllib.request
import urllib.parse
import urllib.error
import math
import time
import logging
import numpy as np
import srtm  # Python 3 version: http://git.io/vl5Ls
import sys
from pygooglechart import SimpleLineChart
from pygooglechart import Axis
import fpdf

try:
    import Image
    import ImageFilter
    import ImageEnhance
    import ImageDraw
except:
    from PIL import Image
    from PIL import ImageFilter
    from PIL import ImageEnhance
    from PIL import ImageDraw

# Python logging module.
# Provides a more advanced way
# to track and log program progress.
# Logging level - everything at or below
# this level will output. INFO is below.
level = logging.DEBUG...
