Overview of this book

Data scientists, when presented with a myriad of data, can often lose sight of how to present geospatial analyses in a meaningful way so that it makes sense to everyone. Using Python to visualize data helps stakeholders in less technical roles to understand the problem and seek solutions. The goal of this book is to help data scientists and GIS professionals learn and implement geospatial data science workflows using Python. Throughout this book, you’ll uncover numerous geospatial Python libraries with which you can develop end-to-end spatial data science workflows. You’ll learn how to read, process, and manipulate spatial data effectively. With data in hand, you’ll move on to crafting spatial data visualizations to better understand and tell the story of your data through static and dynamic mapping applications. As you progress through the book, you’ll find yourself developing geospatial AI and ML models focused on clustering, regression, and optimization. The use cases can be leveraged as building blocks for more advanced work in a variety of industries. By the end of the book, you’ll be able to tackle random data, find meaningful correlations, and make geospatial data models.

How do I choose between these models?

When choosing between these various types of models, it is important to understand your data as well as the assumptions that go into each of the various models. It is also important to balance model performance with your individual operational constraints, such as how long you’re willing to wait for model results. Here are a few questions that you can ask yourself to help determine which model may be better for each situation:

  • Do the patterns between my target and explanatory variables vary across space?
    • If the answer to this question is yes, then fitting a GWR or an MGWR model may be a better-suited option, as OLS fits a global regression compared to the local regression fit by GWR and MGWR.
  • If the patterns between my target and explanatory variables vary across space, do they also operate at different scales?
    • If the answer to these questions is yes, then MGWR is a better-suited option than GWR. Recall that GWR assumes a single...
