11. Coordinate reference systems

Tutorial Objectives

Polar stereographic view of the Arctic centred on the North Pole, showing Greenland and the surrounding land in a CRS other than Web Mercator

This tutorial explains Coordinate Reference Systems (CRS) in the Geospatial Explorer: why they matter, how the Explorer handles them, and how to configure them.

By the end of this tutorial you will be able to:

  • Understand why a map needs a CRS, and why you might choose a different one for your data or audience (for example, regional grids or polar views).
  • Understand how the Explorer handles CRS — data is reprojected on the fly to the display CRS — and which CRS are supported out of the box (EPSG:3857, EPSG:4326, EPSG:3035, and the polar stereographic options).
  • Understand how to set a different CRS as the default display for a configuration, and see the effect in Preview.
  • Understand how to add an additional CRS to a configuration so it becomes available as the default or per-layer display option.
