What Will You Learn? { see learning outcomes on syllabus }

• Theoretical

– broaden base of GIS theory established in GEO 465/565

– build entry points into GIS research literature

– cover sets of topics in GIS research & practice, with a focus on the geosciences / coastal & marine sciences

What Will You Learn?

• Theoretical

– consider expanded capabilities of GIS in more detail and relate them to YOUR current work

– rethink the characteristics of spatial data, of spatial analysis procedures

– all about putting technology to work EFFECTIVELY

What Will You Learn?

• Technical

– Practice w/ Windows XP as a working environment for GIS

– build a base of knowledge in ArcGIS 9

– apply GIS methods to problem-solving / project completion

– work toward professional level GIS skills

TextbooksRequired:

Geographic Information

Systems and Science

by Longley, Goodchild,

Maguire, Rhind, 2005, 2nd edition

1st edition works too

Modeling Our Worldby Zeiler, 2001

Map Analysis: Procedures and Applications in GIS Modelingby Joseph Berry, completely online

Optional

Designing Geodatabasesby Michael Zeiller, 2004

Required Project - 2 options

• Option 1 - LABS– Tuesday labs in ArcGIS

– ArcGIS data models, spatial analysis, networks, surfaces, digitizing, metadata

– Take FINAL exam

• Option 2 - analytical project– apply course concepts to your own project (thesis or

dissertation)

– poster or web site, 10-20 page paper, and 10-15 min. presentation during Dead Week

– No FINAL

Option 2 - Proposal• (1) Experience - Your previous experience with GIS (previous

GIS coursework?, previous GIS experience during an internship or job?)

• (2) Analysis - The question or problem that you would like to address during your analytical project. – "I am studying a species of salamander in the WA Cascades, the

Van Dyke's salamander. I am doing a habitat association, model building exercise. What are the difference in habitat between streams and seeps where the salamander was detected compared to those where the salamander was not detected? I would like to take the opportunity available in this class to explore differences in these sites on a landscape level. I will compare sites where the salamander was vs. was not detected at the watershed level, using GIS layers supplied to me by the Gifford Pinchot NationalForest. I will choose two variables to compare: watershed size above the location of each site, and dominant seral class (or canopy closure) on the watershed level.”

• (3) Data - If not already mentioned above, state where you hope to obtain your data if you don't have it already

Project Options (cont.)

What Kinds of Jobs Exist in GIS?

• (1) System developers – highest level of technical skills

– programmers in Visual Basic, Java, C++, C#, Python, UML, Visio, CASE

– 1,000 people

• (2) System maintainers – moderate to high technical skills

– modify existing code in Visual Basic, Java, Python

– 10,000 people

What Kinds of Jobs Exist in GIS?

• (3) System users – moderate technical skills – know how to use the tools– familiar with the technical issues– know the application domains– work for univ., corp., govts.– 100,000 people

• (4) General public – minimal to moderate technical skills

– Know how to use some tools – 1,000,000 people

Success as (3) System User?

• the basic principles (GIS education)– still there when the software changes

• how to be a demanding skeptic– demand better documentation

– reliable and accurate results

– fixes for bugs

• what GIS means– what the data mean in the real world

– what operations mean

GISystems, GIScience and GIStudies

GISystems

GIStudiesGIScience

GISystems, GIScience and GIStudies

• GISystems (GIS)– Emphasis on technology and tools– “GIServices”– Implements storehouse of GISci knowledge

• GIScience (GISci)– Fundamental issues raised by the use of GIS and related

technologies (e.g.)• Spatial analysis• Map projections• Accuracy• Scientific visualization

– Systematic study of the use of geographic information

• GIStudies (GISt?)– how systems and science are embedded in a

societal context, applications

G. I. S. ?

• Geographic Illusionary System

• GRASS Interpolates Sushi

• Gastro- Intestinal Sophistication

• Geometrically Increasing Silliness

• Going In Style

• Gee, I'm Spatial!

Hands-on practical training?

• software changes often (every 2 years) • hands-on experience

– reinforces basic principles

– encourages you to be a demanding skeptic

– encourages thinking about what GIS means

ArcGIS 9

ArcTools 9 w/in ArcGIS

ARC/INFO, ArcInfo

• the workhorse of GIS• the engine behind ArcGIS• command-line interface

– required syntax

– difficult to use

ArcInfo 9

• “easy-to-use” version • several hundred person-years invested • complete rewrite, first since 1980

– version 7 became “ArcInfo Workstation”, the core of ArcGIS 8 and 9

– ArcInfo Desktop, WIMP, wizards

– ArcView is now a subset in ArcGIS 9, along with ArcInfo, ArcSDE, ArcIMS, ArcObjects, etc.

– bugs in ArcGIS 8 worked out?

– Reworked labs in ArcGIS 9 w/Oregon data
