Overview of this book

Geospatial development links your data to places on the Earth’s surface. Its analysis is used in almost every industry to answer location type questions. Combined with the power of the Python programming language, which is becoming the de facto spatial scripting choice for developers and analysts worldwide, this technology will help you to solve real-world spatial problems. This book begins by tackling the installation of the necessary software dependencies and libraries needed to perform spatial analysis with Python. From there, the next logical step is to prepare our data for analysis; we will do this by building up our tool box to deal with data preparation, transformations, and projections. Now that our data is ready for analysis, we will tackle the most common analysis methods for vector and raster data. To check or validate our results, we will explore how to use topology checks to ensure top-quality results. This is followed with network routing analysis focused on constructing indoor routes within buildings, over different levels. Finally, we put several recipes together in a GeoDjango web application that demonstrates a working indoor routing spatial analysis application. The round trip will provide you all the pieces you need to accomplish your own spatial analysis application to suit your requirements.

Introduction


Topology rules allow you to enforce and test spatial relationships between different geometry sets. This chapter will build an open source set of topology rules that you can run from the command line or integrate in your python programs.

The spatial relationships described by the DE-9IM (Nine Intersect Model) are Equals, Disjoint, Intersects, Touches, Crosses, Within, Contains, and Overlaps. However, exactly how these are related is something that's unclear for most beginners. We are referring to the interior, boundary, and exterior of our geometry types: Point, LineString, and Polygon, which are used directly to perform the topology checks. These are as follows:

  • Interior: This refers to the entire shape except for its boundary. All geometry types have interiors.

  • Boundary: This refers to the endpoints of all linear parts of line features or the linear outline of a polygon. Only lines and polygons have boundaries.

  • Exterior: This refers to the outside area a shape. All geometry...
