Keeping location data up to date is critical, but manually updating databases every night does not scale. In this beginner-to-intermediate course (Python and SQL basics required), you will learn how to build, automate, and monitor a real-world geospatial ETL pipeline from start to finish.
Through three progressive lessons, working through the practical scenario of nightly address updates, you will convert raw CSV data into spatial records using PostGIS, schedule reliable pipelines with Airflow, and analyze failures using logs and monitoring tools. Through short videos, hands-on learning, Coach-guided reflections, and scenario-based decision making, you will move beyond theory into applied data engineering.
You are required to have basic Python skills, familiarity with CSV files, and introductory knowledge of databases and SQL. By the end of the course, you will have the confidence and skills to build production-ready geospatial pipelines that run automatically, recover from failures, and alert you when intervention is needed.
In this module, you will discover how raw CSV address data is transformed into spatially enabled database records. Starting from first principles, you will build confidence with ETL thinking and apply it by loading geospatial data into PostGIS. This module focuses on doing, not memorizing.

When will I have access to the lectures and assignments?
To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course. You can try a Free Trial instead, or apply for Financial Aid. The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
What will I get if I subscribe to this Specialization?
When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.
Is financial aid available?
Yes. In select learning programs, you can apply for financial aid or a scholarship if you can’t afford the enrollment fee. If fin aid or scholarship is available for your learning program selection, you’ll find a link to apply on the description page.
