Practical Vector GIS
The theory behind GIS
And
Using ESRI’s ArcGIS
Technology
1
Two flavors of GISs
• Vector GIS
• Raster GIS
– Objects
represented by:
•
•
•
•
– AREA represented
by:
points
lines
polygons
large database each
object
• Grid cells
• one value per cell
• Large number
thematic layers

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

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 fast pased
and there is a
lot to learn
• It is computer
intensive and thus
can be very
frustrating!
10
• 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
12
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
