This course provides an introduction to online spatial data handing. The first modules will describe the theory of cloud computing and cloud services architecture. This will be followed by details of spatial cloud computing, including cloud service models, microservices architecture, and containers. Through a combination of lectures and hands on exercises using Jupyter Notebooks, the students will learn to explore, query, process, and visualize geospatial data in the cloud and to share their notebooks such that others can use, edit and re- use them.
