A Gentle Introduction to GIS
Datums! Coordinate systems! Map projections! Topologies! Spatial applications are a nebulous, daunting concept to most Pythonistas. This talk is a gentle introduction into the concepts, terminology and tools to demystify the world of the world.
This talk will have multiple parts:
- What is GIS?
- Types of data
- How do you talk about spots on earth?
- What is a datum and why does it matter?
- Spatial reference systems: WUT?
- Map projections: what's appropriate and what's web mercator
- Great circle distances and geodesy (or, your lines are wrong and you should feel bad)
- Overlay operators
- Clementini operators
- Buffer, clip their friends
- Will demonstrate concepts with commercial tools (the ArcGIS stack) and some open source (GDAL, OGR, QGIS).
