1. Organizing Layers in ArcMap … … as well as your data folders! You can make Group Layers in your TOC to keep your layers sorted. This is similar to organizing your data in folders, but sorting your layers within your.mxd! This is good for your brain.

2. Exercise 12: Boulder Creek Watershed Working with hydrology on a DEM

3. Modeling flow: Vector Approach Raster Approach Uses nodes as stream junctions Uses DEMs for modeling flow surfaces

4. New Tools: Slope Fill Flow Direction Flow Accumulation Reclassify Raster to Polyline Flow Length Today we’re thinking in pixels! Except for this guy for cartography:

5. Flow Direction on a Raster: Think about elevation values and how the cells relate to each other in space This is an example of a neighborhood function

6. Boulder Creek watershed is highly studied! To dive in deeper to this topic, Google ‘Critical Zone Observatory’!

7. The September 2013 Flood:
