Learning Geospatial Analysis with Python

Summary

Elevation data can often provide a complete data set for analysis and derivative products without any other data. In this chapter we learned to:

• Read/write ASCII Grids using only NumPy
• Create shaded reliefs, slope grids, and aspect grids
• Create elevation contours
• Transform LIDAR data into a grid
• Visualize LIDAR data with PIL
• Create a TIN

In the next chapter we'll combine the building blocks from the previous three chapters to do some advanced modeling and actually create some information products.
