Python Training

Intermediate Geospatial Analysis in Python

This is a course for GIS analysts, scientists, engineers, surveyors, and other data analysts with prior experience working with spatial data in Python.

Prerequisites

Completion of the Python Charmers Python for Geospatial Analysis course and six months Python programming experience.

Expected Outcomes

This course will let you take your spatial analysis further using powerful methods to discover new information using location.

At the end of the course you will understand scientifically and statistically grounded methods of geospatial analysis that you can use to aid in your interpretation of real-world data and to solve real-world problems.

You will learn fundamentals of network analysis through automation of common geospatial tasks, the basics of dealing with network data, as well as more advanced spatial statistics such as measures of spatial autocorrelation and multi-dimensional interpolation and regression. You will also learn techniques for dealing with very large datasets through parallel processing and visualization.

Course Syllabus

Session 1: Automating geospatial processes

Day 1 of the course will revise core concepts, introduce network analysis, and look at common geospatial analysis tasks to automate your workflow and analysis:

  • Revision of key concepts and tools for Geospatial Analysis in Python with geopandas and xarray
  • Mapping the locations of addresses with geocoding with geopy
  • Rasterization, vectorization, and skeletonization: converting old map images to vector data with rasterio and scikit-image
  • Finding the most cost effective path with cost-path analysis.
  • Measuring the flow and capacity of a network: an introduction to network analysis with NetworkX and osmnx
    • How many people can reach the city on trains in rush-hour?
    • How many houses will be without water if a water-main is broken?
  • Automating an analysis process in Python. Updating from remote data sources, analysis, automatically produce a map of your results.

Session 2: Extended analysis of spatial data

Day 2 looks at extending this analysis. You will learn how to perform spatial autoregression tests for spatial dependence, work with point pattern datasets for optimisation and to interpolate surfaces, before finally techniques for managing and visualising large spatial datasets:

  • Measuring spatial dependence with pysal:
    • How much do property prices depend on the location of different schools?
    • Can you detect spatial dependence in illegal graffiti locations?
    • Mesuring air pollution hotspots
  • Creating better boundaries from points as concave hulls. Delaunay triangulation, Voronoi tesselation, and point pattern analysis with scipy, shapely and pysal
  • How many pedestrians are in walking through the city of Melbourne right now? Spatial data interpolation and regression with scipy and scikit-learn
  • Large-scale raster analysis: memory-efficient and parallel techniques with dask, rasterio, xarray. Example: remote-sensing indexing
  • Visualization of large-scale datasets with datashader

Personal help

We are happy to offer on-the-spot problem-solving after each day of the training for you to ask one-on-one questions — whether about the course content and exercises or about specific problems you face in your work and how to solve them. If you would like us to prepare for this in advance, you are welcome to send us background info before the course.

Other information

Format:

Courses are conducted online via live video meeting and using Python Charmers' cloud notebook server for sharing code with the trainer(s).

Computer:

Hardware: we recommend ≥ 8 GB of RAM and a webcam. Preferably also multiple screens and a quiet room (or headset mic).

Software: a modern browser: Chrome, Firefox, or Safari (not IE or Edge); and Zoom.

Timing:

Most courses will run from 9:00 to roughly 17:00 (AEST) each day, with breaks of 50 minutes for lunch and 20 minutes each for morning and afternoon tea.

Certificate of completion:

We will provide you a certificate if you complete the course and successfully answer the majority of the exercise questions.

Materials:

You will have access to all the course materials via the cloud server. We will also mail you cheat sheets and a USB stick with all the materials for reference.
