Learning Geospatial Analysis with Python - Third Edition

By: Joel Lawhead

Overview of this book

Geospatial analysis is used in almost every domain you can think of, including defense, farming, and even medicine. With this systematic guide, you'll get started with geographic information system (GIS) and remote sensing analysis using the latest features in Python. This book will take you through GIS techniques, geodatabases, geospatial raster data, and much more using the latest built-in tools and libraries in Python 3.7. You'll learn everything you need to know about using software packages or APIs and generic algorithms that can be used for different situations. Furthermore, you'll learn how to apply simple Python GIS geospatial processes to a variety of problems, and work with remote sensing data. By the end of the book, you'll be able to build a generic corporate system, which can be implemented in any organization to manage customer support requests and field support personnel.

Reports from the field

In our final example in this chapter, we'll get off of the bus and out into the field. Modern smartphones, tablets, and laptops allow us to update a GIS and view those updates from everywhere. We'll use HTML, GeoJSON, the Leaflet JavaScript library, and a pure-Python library named Folium to create a client-server application that allows us to post geospatial information to a server and then create an interactive web map to view those data updates.

First, we need a web form that shows your current location and updates the server when you submit the form with comments about your location. You can find the form here: http://geospatialpython.github.io/Learn/fieldwork.html.

The following screenshot shows the form:

You can view the source of that form to see how it works. The mapping is done using the Leaflet library and posts GeoJSON to a unique URL...
