  • Review whats happening next week
  • Geocoding
  • Ponder the future of GIS
  • Geocoding Tutorial (7.1 only)

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
Emergency dispatch operators geocode an address
to determine who should respond to an emergency
call You driving to your friends house in
Denver using MapQuest.com Businesses map your
home zip code to understand regional purchasing
characteristics to fine-tune their marketing
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.

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.

Address geocoding
  • The software module that performs the geocoding
    is usually called the geocoding editor.
  • ArcMaps geocoding editor is as follows we
    select Geocode gt Addresses, and then specify 1)
    an event table, 2) a reference theme, and 3) an
    output shapefile.

Address Matching in ArcMap
  • Create a new Address Locator in ArcCatalog
  • - 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)

16
In ArcCatalog, create new Address locator
17
In ArcCatalog, specify the reference data
(referencetheme) to which the address records
(event table)will be matched
The PAZIP.shphas zip codepolygons. We are
geo-coding zip-codes col-lected at anart
event.
18
In ArcMap, open the Address Locator Manager
19
In ArcMap, perform a match. You specifythe
event table (art show attendees), soon to be
geocoded to the existingreference theme
(PAZipCodes.shp).

You have just geocoded by zip code!

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.

http//catholicgauze.blogspot.com/2007/03/
  • Should GIS separate from geography?

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.

According to Roger Tomlinson (2009)
  • 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. Im very positive about the
    future of GIS. Its 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.

  • Open source GIS

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
