What is GIS
Computerized
mapping software Formal definition
A computerized
Two components
Software ArcGIS (Most popular
software in higher education )
databasemanagement systemfor capture, storage,retrieval, manipulation,analysis and display ofspatial (i.e. locationallydefined) data
GeoMedia
Google Earth (not analytical)
Data (information)
Any data withspatial/geographic info
ArcGIS
There are many generalpurpose GIS products on themarket, ArcGIS, MapInfo,GeoMedia, etc.
(Environmental SystemsResearch institute, Inc.) basedin Redlands, California
Probably the most popular GISsoftware
Current version is ArcGIS 10
(Quick) History of GIS
In the mid 1960s: the fist GIS, theCanada Geographic Information System,was created by Roger Tomlinson
Around that time US Census Bureau
1960
1970
1980 system, called DIME
1982, ESRI released ARC/INFO
BUT, until about 1990, most maps wereprinted from handmade drawings orengravings thus, it is hard to find pre1990 GIS data!
1990
2000
Why GIS ?
Add new analytical dimension(space!) to your research
90% of data are geographic in nature -Profiting from a Geographic InformationSystem, p.109.
Pre GIS maps
Charles Booths maps of poverty
Booth, a Victoriansociologist, conducted a
survey of working class lifein London between 1886and 1903. His work wasalso published in a form ofmaps, visualizing the level
of poverty by location.

Pre GIS maps (cont.)
Hull-house maps and papers (1895)
A Hull-house resident, Florence Kelly two setsof maps, similar to Booths poverty map (but
with more details), based on a survey for the, .

Each property was colored to reflect the
birth place of the head of the household
in instance of multiple households in aproperty, the color was allocatedspatially in proportion to the number of
household heads.

The meteorological Journalrecorded :
- Direction & force ofwind
- Weather- Air pressure- Air & water
temperatures- Locality
- coordinate (lat/long)or- place name
The information was copiedand saved in Excel. Datawas carefully examined and
reformatted so that eachrecord represents each daybetween December 27, 1831and October 2, 1836. Place
names in the localityfieldwere translated into numericgeographic coordinates(latitude & longitude.)
GIS (Geographic InformationSystem) can map various
types of geographicinformation, such as country& place names, zip codes,street addresses andgeographic coordinates.
ArcGIS 9.3 by ESRI wasused to map the reformattedmeteorological journalrecords.
The meteorological records ofthe Beagle are like an ancientform of GPS both recorddetailed geographic locations.
Here is the mapping result ofthe daily ship locations.Note: sometimes the Beaglestayed in the same locationfor a long time, making it hardto see all ship locations (or

Policy Implications
Current Illinois LawIt is unlawful for a child sex offender to reside within 500 feet of a school,
playground, or any facility providing programs or services exclusively
directed toward people under age 18**, unless they owned the property**pr or to u y 7, 2000. nc u es par s, ay-care centers an pu c

Trend impact of the Adam Walsh Child Protectionand Safety Act of 2006?
Increase of the safety zone what if Illinois/Chicago change the restrictionfrom 500 feet to 1,000 feet, or even higher?
Iowa = 2,000 feet
Florida = 1,000 feet, Palm Beach County (FL) = 2,500 feet!

What is Geographic Information ?
Any information that contains geographic orspatial information
However, in GIS the information must be
readable to computers in order to use it Often called (inter-changeably)
Geographical information (or data)
Geospatial data
Spatial data
Vector and Raster
Two types of Geospatial Data
Vector data represents the real worldusing three types of geometry
Points
Large riveras a polygon (area)
Small creeks
as lines
Lines
Polygons / Areas
Raster data is a cell table
Columns (Y) x Rows (X)
Each cell contains a numeric value
Either integer or floating points
Populated areasas points

Vector: Shapefiles
Shapefiles are the common geospatial dataformat for storing both geometry (shape) and
attribute (table) information of geographicfeatures
Almost an industry standard
Vector: Shapefiles (cont.)
Why is it called shapefiles??
Because they consist of three or more files
extension Type
.shp The main f ile that stores the feature geometry
.shx The index file thatstores the index of the feature geometry
.dbf The dBASEtable that stores the att ribute informat ion
.sbn& .sbx The files that store the spatial index of the features
.pr j The fi le that stores the coordinatesystem information
.xml Metadata for ArcGISthatstores information about theshapefiles

Vector: Coverage
Outdated georelational data
model used in ArcInfomodule
Vector coverage looks justlike shapefiles
Requires multiple files (toomany!) and thus hard tomanage
Easily get corrupted
Vector: CAD drawing
CAD (Computer Aided Design)
AutoCAD
.DXF ascii/text file
.DWG binary file
Intergraph Microstation
.DGN binary file
CADs are graphic drawing tools
Used mainly by engineers, surveyorsand architects
Limited analysis & databasecapabilities
ArcGIS can view CAD files but with
limited editing capability
Raster: Grid
Raster consists of a matrix of cells (or pixels)organized into rows and columns where eachcell contains a value representing information
When representing space, rasters store theocat on an c aracter st cs on eac ce s
Raster: continuous surface
Rasters are well suited for representing thatchanges continuously across a landscape(surface.)
Examples: Elevation
Temperature
Population density

Raster: Discrete data
Rasters can also represent discrete (or
thematic, or categorized) maps, such as: Landcover & Landuse

New: Geodatabase
Both vector and raster data can be stored in a spatially-enabled relational database management system(DBMS), called geodatabase
Easier to contain and maintain geospatial data
Corporate (large DBMS)
Oracle, MS SQL Server, IBM DB2, PostgreSQL
Personal
Microsoft Access database
Vector/Raster: Geodatabase (cont.)
However, it is not suitable for sharing theinformation (interoperability problem)
In my opinion, any way
ArcGIS eodatabase is robabl read b ArcGISsoftware only
Isnt stable yet (in my opinion..)
So, we are going to stick with more conventionaldata types NO geodatabase until very end ofthis workshop
Metadata
Data about data - metadata are data (or documentation)files that describe the contents of other data files.
Readme.txt
xxxxx.met (metadata text file)
xxxxx.html (metadata HTML/web file)
xxxxx.xml (metadata XML file ArcGIS uses this)
Metadata files help you determine if the data are likely tomeet your needs.
FGDC metadata standards
FGDC: Federal Geographic Data Committee
The most popular metadata standard for geospatial data
Users need to know how to read files
7 elements Main entries
Identif ication Tit le, coverage,keywords, purpose, abstract, restr ictions
Data Qua li ty Accur acy assessment , completeness and lineage
Spatial Data Organization Datatypes (vector/raster), ink to location
Spatial Reference Coordinate system, map projection
Entity &Attribute Definit ionsof attr ibutes of the dataset
Dis tr ibut ion Information about d is tr ibutor, suchas f ile fo rmat , media type ,links
Metadata Reference Who,when and how the metadata was created

About GIS (geospatial/spatial) data
Who produces GIS Data Are data available?
About GIS data
Data sources
Who produces GIS data ?
Answer: Government !! (generally)
Most geospatial data (maps, aerial photos,satellite imagery & GIS data) were produced byvar ous eve s o governmenta agenc es tosupport their missions
Such as: Administrative decisions
Management
Policy making
Taxation
Are GIS data available to us?
Data accessibility mostly depends on thegovernment's data access policies & laws
U.S. Federal government
Data created b federal a encies are inthe ubl icdomain with a few exceptions (i.e. security & privacyreasons)
State & local government Data access policies vary Reasons: cost recovery, reliabilities (or hesitation -
they dont want to be sued for providing data)
Other countries Vary though, data access is often limited
About GIS data
Principles Geospatial data is expensive to produce
Most data producers consider their data ascommodities
Cost recovery o not assume ree access an ree usage Exception: the U.S. federal government data Data can be copyrighted you can use data but your use is
limited Data can be licensed license terms specify who can
access/use and what can be done with the data
Data MUST be treated with care Must know the data usage restrictions before
using it
About GIS data (cont.)
How do we know what kind ofrestrictions are imposed?
Always look for and readdocuments accompanied
,files, metadata, license,disclaimer, warrantee,etc.
If not finding information thatyou need, ask dataproviders first, and then dataproducers
