```					NEEDS FOR NEXT TIME:
FINAL PROJECT: Require program, with disk turned in that runs – either AML or Avenue.
Statistics : they didn’t get cell statistics – lectures are changed, but emphasize.
GRID: maybe start earlier?

Description: GIS methods applied to environmental analysis and                                             soil toxins
studies of physical geographic systems. Emphasizes
raster GIS: analysis of continuous data, such as most
applications in environmental and natural resource
management, physical geography and other natural and                                                aquifer
physical sciences. We'll explore methods in map algebra,
image integration, surface and flow modeling. The
methods are centered on a raster GIS model, using the                                                slope

software. Good complement to Geog 620, which focuses on building map datasets, and using discrete data
and vector mode analysis; combining raster and vector modes provides a complete toolkit. The topics to be
covered include
   Introduction to GIS for Environmental Analysis
   Grid and Image Display and Query. There are important differences in displaying grids as compared to
vector coverages (fortunately we can do both at the same time, and we'll explore this too). Earth images are
also stored in a raster structure, and images are a valuable source of information for environmental analysis.
   Raster GIS data structures, and data conversion
   Map Algebra. Map algebra provides a straightforward way to analyze research questions, and allows us to
combine digital maps quickly, and start analyzing things quickly in Grid
   Functions. We will learn about various spatial classes of functions used to process gridded maps: local, focal,
zonal, block, and global functions. These allow us to either deal with grid cells as individuals (local), as
neighborhoods (focal), as groups of cells with identical values (zones), as new spatial aggregates (blocks), or
reflecting general trans-grid phenomena, e.g. distances from features (global).
   Surface Modeling, Display & Analysis
   Hydrologic Modeling
   Grid Modeling. Modeling environmental analyses with raster
GIS
   Extending the GIS with external programs and statistical
analysis.

Course Structure: Lecture/Laboratory, based upon units:
classroom, two units; laboratory, two units. Sequence of 8
regular exercises (in 4 sets) and one final project. Real-world applications of the tools are emphasized
throughout.
a. textbook: Burrough, Peter A., and McDonnell, Rachael A. (1998). Principles of Geographical
Information Systems. Oxford, 333 p.
 emphasizes raster GIS and environmental applications
b. assigned readings, in map library: various research articles applying GIS to environmental analysis
problems.
c. printed lectures and lab assignments, in map library

Grading Policy: Out of 100 pts: Exams 2 x 20 pts ea; Regular exercises total 30 pts; Final project 30 pts.
Late Exercise Policy: exercises -1 pt during 1st late week, -2 during 2nd, etc.; final project: -1 pt/weekday
Exam Dates: Oct. 15 (class time), Dec. 15 (1:30-4:00 pm)

ESRI Training Modules
We will make use of a few online training modules offered by the developers of Arc/Info and ArcView, as
introductions to the software we'll be using. These free modules are introductions to online training
courses offered by ESRI, the full course having a cost, but they will serve us well to introduce the
programs. Each of these modules can be completed at any computer with the needed software installed,
including ArcView, the Spatial Analyst extension, and the 3D Analyst extension:
Course                                  Module                                Software Required
Conservation GIS         "Analyzing Habitat Loss for Endangered Species"                   ArcView
AV Spatial Analyst                 "Basics of Spatial Analyst"                  ArcView & Spatial Analyst
AV 3D Analyst                       "Basics of 3D Analyst"                       ArcView & 3D Analyst
When a given module is assigned (see the syllabus), you will need to use both a browser (Netscape) and
the software specified. When instructed, download the data from to your zip disk, and uncompress it to
reside on your zip disk. To complete a module, go through it in its entirety, including the exam, and print
off the "diploma" to hand in.
