Changing Emphases
from 2-D description to 4-D interaction
Past • 2-D flat map displays
– User as observer
Future • Effective 3-D visualization
– Via the merger of CAD and GIS? – What is the data model?
• 4-D incorporation of time: “The time has come for time.”
– Via agent-based modeling / cellular automata? Or how?
• agents (e.g. vehicles, fires or people) interacting over time in a raster (cell)-based environment according to established rules
• 5, 6 and 7-D incorporation of touch (pressure, texture, temperature), sound and smell into modeling/simulation environment
– Aldous Huxley‘s Brave New World ―feelies‖ become reality?
• User as participant
– Users (researchers, professionals, the public) interact with the model – Participatory GIS: the public as the planner

Changing Emphases:
Out of this world
Past
– GIS applied to Planet Earth
Future
– GIS as a methodology for the analysis of spheres
• Other planets—Mars, Jupiter, • The human brain
– One earth but many brains – & visa-a-versa: does the brain use ―maps‖ for organization?

Astrography
• A map of the nearby Universe --- some 9300 galaxies each represented by a dot. The survey shows two slices across the sky plotted against the redshift (or indirectly, distance) of each galaxy. Several large structures (walls) can be clearly seen as well as large voids where galaxies are relatively absent.
11/19/2007 Dr. Stuart Murchison, UTDallas GISC 6381 GIS Fundamentals
10
Astrography
• Surveys like the one above map the local Universe by measuring the position in 3D space of galaxies up to a few hundred Mpc away. The observable Universe has a diameter of order 10 Gpc. To find and observe galaxies at large distances (and therefore in the early Universe) requires large or special telescopes. The formation of galaxies is not well understood, although the field is beginning to open up. The figure above shows the start of the art at present, in which galaxies have formed in a computer simulation of the gravitational collapse of the initial perturbations which came from the big bang. The simulations are difficult to compute because the effects of gas dynamics and star formation in the forming galaxies is very poorly understood.

Consequences
GIS gone by 2010? (I used to say by year 2000) Hopefully not! …it will become mainstream
11/19/2007 Dr. Stuart Murchison, UTDallas GISC 6381 GIS Fundamentals
14
Wither GIS?
some scenarios
• fundamental component of IS/IT
– value explode, name gone
• foundation for all data management?
– at best: geography becomes the basis for data management – at least: spatial data base management tools come with all commercial DBMSs so geography can enhance the enterprise data base
• gis/am/fm functionality purchased as undifferentiated component of a business application information system
– outage management for utilities – city business package – package tracking system (pizza or spare parts)
• gis components embedded in everyday objects
– cell phones, pagers, cars, truck cabs, aircraft cockpits
• general public as GIS analyst
– Web-based community information systems
• neighborhood crime control : police or citizen?
• gis capabilities available as modules within standard software application development environments
– VB, C++, Java, Peoplesoft, Delphi
11/19/2007 Dr. Stuart Murchison, UTDallas
– poets that don‘t know it
• Google Earth Sketch-up
– Bloggers as GIS analysts: they know the local scene
• And Google is bringing free, simplified mapping tools

Consequences: for GI Services
• Services now the 4th ―S‖ in GIS • location based services
• • • • Map Geocode Route Analyze
for organization facilities customers deliveries the market
. for individual where I am where I want to go how I get there what is there
• Content tailored for current location, not the desktop
• Mobile • Handheld • Interactive
• Evolution involves
Past Future – Few applications -> many and varied – Few users -> many – Standalone -> web – Fixed -> mobile
11/19/2007 Dr. Stuart Murchison, UTDallas GISC 6381 GIS Fundamentals
16
Consequences: for GI Specialists
(the fifth “S” for GIS?) geospatial information scientists, specialists (or students)
– appreciative of the broad ranging, integrative role geospatial data can play
• location is the most common common denominator for all data
– highly knowledgeable with respect to the unique challenges of geospatial data
• The challenges posed by a spherical earth (datums, projections,etc.) • The complexity of spatial data representation in 2-D and 3-D • The challenges of spatial statistics and modeling
– fully conversant with mainstream information technology
• and how to store and program spatial objects
– sufficient expertise in an application area (geology, local government, marketing, etc.) to make a contribution.

17
Consequences for GIS
Data is still at the heart
• Dominant IT (Information technology) issues:
– Hardware in the 1970s and 1980s – Software in the 1980s and 1990s – Data in the 2000s
• Not an issues of acquiring data, but of managing it • Will we be short of it, or drowning in it? • Will its availability be
– Plentiful and cheap – in infinite detail, if you can afford it – Severely curtailed by legal controls to ensure personal privacy
11/19/2007 Dr. Stuart Murchison, UTDallas GISC 6381 GIS Fundamentals
18
Consequences for GIS:
is a Tragedy of the Commons in the making?
• Invasions of privacy through detailed data collection and its pervasive distribution produces a backlash of demand for privacy
– No call, no spam, no appraisal photos, no red light cameras (now reversed): are they the beginning? – Could geotagging with RFID devices become reality
• From pets to people • for sex offenders, service personnel, employees, evacuees, everybody?
• The expense of data production, but the ease of re-production and distribution, reduces the value of data to zero and chokes off its availability
– Is public domain data the information age equivalent of the agricultural commons?
What are the appropriate public policy responses?

Conclusion
• Our only model for the future is the past • think back as many years as you are looking forward
– change has been both revolutionary.. and glacial
• don‘t forget that the pace of change is accelerating
– maybe just gearing-up for the information age, not reaching its climax
• but remember,we have to get there from here
– can you envision a path?
• if we knew the future, we wouldn‘t be here!

What GIS Technology Could Deliver:
Efficiency and Effectiveness
• Cost efficient, quality service to customers: the key to future business success
• mapping to manage potentially transforms organizations • geography is the key to cost efficiency for pizza delivery or cellular radio towers
• communications with citizens: the key to future public sector success
• map based information is the key to intuitive information delivery

What GIS Technology Could Deliver:
Targeted Communication
Displaying data differently for today’s target constituency: *CC: Chamber of Commerce
• • • • • •

Do-It-Yourself extraction from Societal Databases
• large, networked databases accessible to public at low/no cost • free browser software (e.g ArcExplorer)
Content tailored for current location
• The mobile, handheld, interactive GI services revolution
11/19/2007 Dr. Stuart Murchison, UTDallas GISC 6381 GIS Fundamentals
26
What GIS Technology Could Deliver:
Data as an Institutional Asset
Data holdings, managed by GIS, as an asset on private and public corporation balance sheets. • no company does this today, yet • billions spent on data acquisition and development In the information age, information is an asset no different from buildings, unsold inventory, and machinery. In 2000s, companies delivering information content become dominant over hardware (1980s) and software (1990s) companies.

Operating Environments: Business & Governments
• customers and citizens take charge
– – – – requirements for service defined by customer/citizen not the provider demand more in shorter time at lower cost than you ever intended to deliver lower taxes/prices and more service Henry‘s ―any color you want as long as its black‖ no longer cuts it
• competition is relentless
– more people wanting to do what you do – private sector assumes (or re-assumes) many gov. tasks.
• change is constant
– Government evolves from driver to consumer of technology – Commercial Off-The-Shelf (COTS) software rather than custom designed
• decentralization to the individual
– Much new technology is not new: its been around for a while, so what‘s new?
• Computers, video recorders, fax, wireless
– Dramatic price drops make it as available to individuals as to organizations

Operating Environments:
Computing Technology: Predictions from Spring 96
• 2,000AD desktop machine
– 1,000 MIPS/MHertz – 8 Gigabyte RAM (permits data in memory) – 100+ mb/sec comm. line (to the home?)
• Windows95/NT merge challenges UNIX • Java /Netscape challenges Microsoft
(prediction as of Spring 96)
11/19/2007 Dr. Stuart Murchison, UTDallas GISC 6381 GIS Fundamentals
29
Operating Environments:
Computing Technology: Predictions from Fall 99
• Desktop loses its dominance
– Variety of computing appliances: palmtops on up
• Computers act rather than just process
– Old model: human enters data, computer processes it, human receives and acts – New model: data from sensors & transducers, computer processes, computer acts to get job done
• Data and computation become real time
– Old model: processing archived data to guide future action – New Model: processing current data to control current action
• Information and its processing at any and every place
– Mobile and wireless dominate over fixed and wired – Info access no matter where I am, where data resides, what its format is
Concepts derived from Tennenhouse, Director, DARPA, May 1998
11/19/2007 Dr. Stuart Murchison, UTDallas GISC 6381 GIS Fundamentals
30
Operating Environments: Information Architecture (more 1999 predictions which have come to pass)
• server and client clearly separated
– GIS vendors specialize in client and/or applications server – mainstream database vendors provide data server(s) (traditionally, GIS vendors used proprietary, not mainstream, databases)
• client systems primarily comprise browsers which receive data combined with software as ―applets‖ or objects from the applications server
– e.g. receive data and zoom/view software – potentially simplifies software management – big software systems are decomposed into components (―objects‖), which are then re-assembled by user (or developer) as desired.
• mainstream data base vendors meet GIS/AM/FM needs for:
– long transaction processing
• current DBMS systems assume immediate transaction processing, but • a drawing or map takes time to be modified
– replication of data files
• considered a no-no in current DBMS, but • two people need to work on the same map area
11/19/2007 Dr. Stuart Murchison, UTDallas GISC 6381 GIS Fundamentals
31
Operating Environments: Interoperability
• Spatial Data Interchange Formats •
– VPF (Vector Product Format): US Military for map products; directly useable by applications – DXF (Data Exchange Format): originated by AutoCAD – SDTS (Spatial Data Transfer Standard): • currently required for Federal Agencies Except for VPF, involve translation (from internal private to external public format), therefore inefficient.
Between GIS Systems and other applications
– COM/OLE (Common Object Model/Object Linking and Embedding): originated by Microsoft – CORBA (Common Object Request Broker Architecture) Two competing standards for object-based technology.
Between GIS Systems Themselves (for data)
– – – – SQL3 --SQL extended to support spatial (and other multimedia) data queries ISO TC211--International Standards Organization Tech. Committee on spatial data ANSI X3L1 (American National Standards Institute, GIS Committee)--US view for ISO OGC (Open GIS Consortium)--Open Geodata Interoperability Specification (OGIS)
datum and projection, accuracy and lineage, etc. FGDC (Federal Geographic Data Committee) Metadata standard
•
Between Standard Data Base Systems
– SQL (Structured Query Language)
• standardized (supposedly) user-oriented (supposedly) data request
•
Metadata--data describing data
– –
– ODBC (Open Database Connectivity)
• standardized (by Microsoft) programming (‗call‘) level interface to databases
