Labs this week will be at posted times, but held at the Stanford Geospatial Center at Branner Earth Science Library.
Look for a Doodle Poll to determine when labs at the A65 Computer Lab will be held.
Waldo Tobler's 1st Law of Geography
"everything is related to everything else, but near things are more related than distant things."

Stace's 1st Law of Geography
Everything is somewhere, and that somewhere matters."

Learning Objectives
The goal of this course is to provide students with hands-on experience in using the latest geospatial methodologies, and to establish the foundation for students to use “spatial thinking” and spatial technologies to enhance their future research and work.

Who is GIS useful for?
Everything is somewhere, and that somewhere matters
Geographic Information Science
is fundamentally independent of specific application areas.
How Does GIS Model the World?
Vector Data
Raster Data
Raster Data is Pixels
Pixels are numeric values
Everything is somewhere, but how do we say where?
Geographic Coordinate Systems
Projected Coordinate Systems
Web Maps
The "special" case of Web Mercator
Thinking "Spatially"
Spatial Relationships
- Adjacency
- Containment
- Intersection
- Proximity
Proximity
Intersection
Zonal Statistics
Simulation
- Hillshade
- Viewshed
- Hydrology
- Movement/Least-cost paths
- Agent-based models
