3. Geocoding is the process of plotting geographic locations for data stored in tabular format.
Address Geocoding is the process of creating geometric representations for locations (such as points) from addresses in a non-spatial, tabular format
4. Geocoding Examples
5. Address geocoding The objective is to match nontoplogical addresses in data files (.txt, .dbf, .mdb) called event tables to topological references in a reference theme.
7. Address geocoding Sources for reference themes
US – Census Bureau TIGER (Topologically Integrated Geographic Encoding and Referencing)
Canada – Statistics Canada AMF (Area Master Files)
UK – Royal Mail PAF (Postcode Address File)
8. Address geocoding TIGER, AMF, and PAF use different structures, BUT all use a topological model that contains a street network and address ranges for both sides of every street.
9. Address geocoding The software module that performs the geocoding is usually called the geocoding editor.
ArcMap’s geocoding editor is as follows: we select Geocode > Addresses, and then specify 1) an event table, 2) a reference theme, and 3) an output shapefile.

- Q: What is an address locator?
- A: An address locator “defines the process for translating nonspatial descriptions of places, such as street addresses, into spatial data that can be displayed as features on a map” (GIS Dictionary - ESRI Support, Accessed April 1, 2008)

24. The future of GIS
25. “When GIS is the pinnacle of everything, geography loses. What is happening is that many GIS users have no knowledge of geography. With a few clicks of a button a GIS jockey can describe data's distribution but cannot explain why things are the way they are. A monkey can do that work.”
26. According to Jack Dangermond (2008) “My forecast is that as society becomes familiar with looking at things through geospatial visualization, they will be increasingly interested in services that go beyond simple maps and images. GIS servers managed by public and private GIS organizations will be used to provide these kinds of complementing services.” Baumann: What developments in GIS do
you anticipate in the next 10 years?
Tomlinson: A lot of the current trends are
going to continue. Hardware will continue to
get cheaper and more powerful. Software will
get easier to use and more robust. I hope the
universities will continue to expand their
course offerings to meet the growing need for
GIS professionals. Senior management will
become increasingly aware of the benefits
that accrue from the use of GIS in their organizations.
We will see more countries adopting
national policies, and GIS will be an important
part of cabinet-level discussions. I hope that
trained geographers will become a part of
national decision-making processes. Also, I
think that high-level military personnel should
have a good knowledge of the capabilities
and potential of a GIS.
I‘m very positive about the future of GIS.
It‘s the right technology at the right time.
When I think of all the major problems that
we face throughout the world today -
overpopulation, food shortages, reduced
agricultural production, adverse climate
change, poverty - these are all quintessentially
geographic problems. These problems are all
concerned with the human relationship to
the land, and this is where GIS can make its
biggest contribution. GIS is the technology of
our times and is uniquely suited to assist in
solving the problems that we face.Baumann: What developments in GIS do

29. Where is GIS going? GISday summary of answers:
Web-based information sharing
so Grandma Jones can use it
“do it yourself” online
interactive
multiple orgs using same GIS
As decision making “proof”
“prove it” visually - people want to “see” advantages
marketing analysis
Real-time applications
transportation (bus syst., pizza, cell phone “where the hell am I”)
medical inter and intranet
Security applications
“The war is being fought with GIS”
Interoperability
to share data (ESRI guy)
For maintenance of networks (pipes, utilities)
Research part will stay same – as needed (ESRI guy)
Less emphasis on standards and more on “filters”
