Summary
This chapter covered the critical components of GIS analysis. We examined the challenges of measuring on the curved surface of the Earth using different approaches. We learned three different ways of measuring distance, how to calculate the direction of a line, perform coordinate conversion, reproject data to different coordinate systems, calculate the area of a polygon, and measure the perimeter, and learned how to ask ChatGPT to help us create new Python scripts.
In the next chapter, we’ll tackle creating and editing some simple GIS formats for common purposes you will encounter.
