#Python Geospatial Development-Third Edition
This is the code repository for Python Geospatial Development-Third Edition, published by Packt. It contains all the supporting project files necessary to work through the book from start to finish.
##Instructions and Navigation
The code included with this book is meant for use as an aid in performing the exercises and should not be used as a replacement for the book itself. Used out of context, the code may result in an unusable configuration and no warranty is given.
The code will look like the following:
import math
lat1 = 42.0095
long1 = -122.3782
lat2 = 32.5288
long2 = -117.2049
rLat1 = math.radians(lat1)
rLong1 = math.radians(long1)
rLat2 = math.radians(lat2)
rLong2 = math.radians(long2)
dLat = rLat2 - rLat1
dLong = rLong2 - rLong1
a = math.sin(dLat/2)**2 + math.cos(rLat1) * math.cos(rLat2) \
* math.sin(dLong/2)**2
c = 2 * math.atan2(math.sqrt(a), math.sqrt(1-a))
distance = 6371 * c
print("Great circle distance is {:0.0f} kilometers".format(
distance))
