Two flavors of GISs• Vector GIS
– Objects represented by:
• points• lines• polygons• large database
each object
• Raster GIS– AREA represented
by:• Grid cells• one value per cell• Large number
thematic layers
Forest road
Cropland stream

Looks like a dog’s breakfastDemo

The Course, briefly
• Shared Resource – grad and undergrad• Slightly different requirements for each• Required Text, so to speak, is the ESRI on-
line course “learning ArcGIS desktop 9.2”• Recommended Text is David Theobald’s GIS
Concepts and ArcGIS methods• All this stuff is in the course syllabus
Demo

So what do we study?
• Working with maps• Mod 1: Getting Started with ArcGIS
Desktop• Mod 2:Creating Map Symbology• Mod 8:Designing Maps with ArcGIS• Whoa! That was a big jump

So what do we study?
• Mod 3: Referencing Data to Real Locations (Theory and practice)
• Mod 4: Organizing Geographic Data• Mod 5: Creating and Editing Data• Mod 6: Getting Started with GIS
Analysis• Mod 7: Working with
Geoprocessing and Modeling Tools

Then…
• We do parts of the ESRI raster course “Learning Spatial Analyst”
• Finally we end with projects – your Project or a canned* one.
*See Syllabus!

So How does it work?
• Each week you do assigned modules and turn in grade via email
• Then you do a Class exercise that uses the concepts from the Module(s) but without any hand holding.

Course Attributes
• It is computer intensive and thus can be very frustrating!
It is fast pased and there is a lot to learn

• Just learn to walk away from a problem, talk it over with someone else in the class or me or the TA and let your subconscious work it out!

What happens this week?
• Labs NOT in Baker, see schedule• Labs are about maps
– Short PP about maps– Then some study of maps

Now to see how good your are!
• A friend has asked you to draw a map of the ESF campus around the quad.
• The friend wants to be able to move between buildings without confusion
• Use the sheet of paper provided – you have 5 minutes
• Your name goes on back, upper right corner
