Brief introduction to Coordinate Reference Systems. Why do we need them; how do we model the earth (sphere, ellipsoid, geoid); Why/how do we use projected systems, like transverse Mercator or LCC. What is on EPSG catalog.
Introduction to basic but important concepts about Coordinate Reference Systems (what is doable in 20 min ;)
- Geographic Coordinate (Reference) Systems
- Different Datums/Ellipsoids
- Projections (Mercator, UTM, LCC, ...)
- EPSG catalog
- WKT (well known text) description
- Reference to PROJ.org library
