Databases
I-Miner on TRI 2000 Public Release Data
17
2.2 Advanced Visualization Tools for EPA Spatial
Databases

• VisiMine and Examples
• VisiMine is a search engine for analyzing image
  databases. Developed by Insightful Corporation
  in cooperation with NASA, VisiMine provides a
  comprehensive workbench for image information
  mining, integrating state-of-the-art statistics,
  data mining, and image processing to extract
  information and locate images from potentially
  huge databases. VisiMine allows you to detect
  "like images" based on a variety of factors from
  immense image collections. VisiMine enhances the
  value of your visual data, lending structure,
  comprehensive search capability, and increased
  accessibility.
• Dr. Giovanni Marchisio has authored and
  co-authored several articles and book chapters on
  automated imagery data mining and computational
  linguistics, and has four US and international
  patents pending on these technologies.

18
2.2 Advanced Visualization Tools for EPA Spatial
Databases
VisiMine and Examples
We teach VisiMine the difference between clouds
and snow. From a satellite, especially if the
targets are mountains in spring, clouds and snow
look very similar-white, patchy, irregular. So we
take a few seconds to teach it using a lasso and
both this is what it is and a this is what it
is not input.
19
2.2 Advanced Visualization Tools for EPA Spatial
Databases
VisiMine and Examples
Once taught the difference, we show an example of
white patches sitting precisely on top of
mountains that your eye and brain tell you with
100 certainty are snow. But VisiMine tells you
they are clouds. Ah-ha! Computers arent so smart
after all! Except that it turns out that VisiMine
is right and our eyes have been fooled.

2.3 Accuracy Assessment and Improvement of EPA
Facility Registry Data and Emergency Notification
and Data Collection with VoiceXML

• Qsent Features
• Over 145 million residential, business and
  government listings (99). Every record verified
  through phone installation and account activation
  with credit history.
• 250,000 to 500,000 updates daily
• Four searches methods
• U.S. Residential search for an individual
• U.S. Business and Government search for
  business or government agencies
• Reverse Lookup search by telephone number
• U.S. All search all directories at once
• Geographic searches
• City Surround expand search incrementally from
  city center (lowest ZIP)
• Neighborhood Search search by neighborhoods
  using ZIP4

22
2.3 Accuracy Assessment and Improvement of EPA
Facility Registry Data and Emergency Notification
and Data Collection with VoiceXML

Qsents iQ411 Applications Interactive,
Integrated, Batch

• iQ411 Interactive is a web-based directory
  information service that provides real-time,
  daily updated, definitively accurate data for
  residential, business and government listings for
  the U.S. and Puerto Rico.
• iQ411 Integrated provides real-time system
  integration using the industry-standard XML API
  to send and receive XML messages and data.
• iQ411 Batch provides off-line processing via
  automated FTP services for accurate appending and
  validation of phone numbers and address
  information.

2.3 Accuracy Assessment and Improvement of EPA
Facility Registry Data and Emergency Notification
and Data Collection with VoiceXML

• Qsent Verification of EPA Regulated Facilities
• Qsent was able to return at least one match in
  1,753 out of 2,533 records in the EPA EnviroFacts
  Data Warehouse in the Portland, OR, area (69).
• Example (see next slide)
• EPA records show Associated Hose Products at 801
  SE Alders in Portland.
• iQ411 shows Associated Hose Products at 130 SE
  7th Avenue and provides a phone number.
• A more thorough analysis of the matching results
  between the Qsent and EPA Facility databases
  would yield improvements in the EPA Facility
  database.

2.4 An Integrated Virtual Workplace for EPA and
Its Partners

• OMBs Mark Forman (E-Gov 2002, June 26, 2002)
• Mark was asked about the reported redundancy in
  state-federal geospatial data activities and he
  responded that the states especially have
  complained about the costs involved, namely 10B
  total (6B Federal and 4B State) and that about
  half of that (5B) is wasted due to duplication
  of effort!
• EPAs CIO Kim Nelson (GIS Day, November 8, 2001,
  and ORD Science Meeting, May 1-2, 2002)
• Everyone needs to think about how to
  geographically reference all of the data that we
  use and collect, so that we can share each
  others' resources. We have 100's of geo-spatial
  data products and resources. We need to develop
  data collection standards which will enable us to
  link and cross-reference these and other newly
  acquired resources.

2.4 An Integrated Virtual Workplace for EPA and
Its Partners

• USGS GEODE (Geo-Data Explorer)
• Fully distributed data analysis and display
  model
• Can link to any data server, world-wide. Can
  import and use their own data (http//pubs.usgs.go
  v/fs/fs132-01/).
• Currently over 6,000 data layers that can be
  retrieved, displayed and manipulated over the
  Internet without any special hardware, software,
  and training.
• Consist of six interoperable modules Data format
  conversion, Spatial data engine, Web server,
  Image compression engine, Map server, and
  Relational database management system.
• Working with the OGIS specifications to become an
  OGIS compliant map server.

30
2.5 Spatially Enabling the EPA with the OGC XML
Standards the OGC Spatial Web Registry Service
(WRS)

• Geography Markup Language (GML)
• An XML-based common encoding for spatial
  features.
• Makes it possible to renders legacy and
  third-party data and services interoperable
  minimizing the coupling between components.
• Enables multi-source, multi-sensor fusion.
• Can be converted to SVG on-the-fly.
• Scalable Vector Graphics (SVG)
• An XML vector graphics standard (W3C) that
  enables them to be processed efficiently,
  robustly, and in an automated fashion and enables
  scaling, panning, highlighting, etc.
• Graphical applications that are currently
  realized using bitmap graphics will start using
  SVG. The scope of SVG use will expand and it will
  displace the use of bitmap graphics in many
  areas, prime examples of which include mapping
  and GIS applications.

45
3.6 EPA Facility Data Homeland Security
Application

• Problem
• EPAs Facility Registry System Database is our
  unique contribution to Homeland Security, but we
  need to know how accurate it is before we provide
  it for that purpose and need it to be delivered
  as a Homeland Security application (XML Web
  Service).
• Strategy
• Provide the FRS as an XML Web Service to Qsent to
  append its Directory Listing Web Services.
• Use the FRS-Qsent Web Service to drive a VoiceXML
  Web Services for Emergency Notification (Reverse
  911).
• Use the FRS-Qsent Web Service to drive Error
  Correction Web Services (VoiceXML and XForms) to
  Validate the FRS-Qsent Web Service and FRS itself.

53
3.7 Geospatial Interoperability with
RedSpiderWeb 3.0

• Ionic Enterprise Pilot Project with EPA, State
  and Regional Data (continued)
• Success Story Examples
• The French "Geological Survey" (Bureau de
  Recherches Gýologiques et Miniýres BRGM with
  850 persons at 22 sites) is currently running a
  vast program called "Virtual Earth" (Terre
  Virtuelle), a portal to data products from their
  own servers or combined with connection to other
  data sources and related to BRGM's advanced
  Catalog, which they are currently organizing
  according ISO19115 metadata model. The geological
  information managed by BRGM includes millions of
  points and more than on million geological tiles.
• Selected by the Ordnance Survey to integrate
  IONIC's robust and powerful OGC-based WFS server
  (RedSpiderWeb) that will produce GML in an
  e-commerce environment. This solution allows for
  dynamic, user-defined, geospatial data products
  to be priced, ordered, produced and delivered
  online to the customer in GML format.

3.8 Geospatial Dynamic Discovery

• Object Builders Pilot Project with State of
  Pennsylvania and Chesapeake Bay Program
• Allowing disparate agencies with information on
  citizens (a person) to register information with
  a registry and allow a rich client application to
  dynamically discover all available information
  sources, query, inform, and present the
  information back with custom views.
• The resulting solution would dynamically grow as
  agencies grow. The published information to the
  registry would have no integration bottleneck
  because the Rich Client Application would source
  the presentation, application logic and data from
  each disparate agency.
• The goal is to leave a functional system so as
  agencies are register their information will
  automatically be available to users of the
  application with NO additional work being
  performed to the original solution.
• The Pilot application would demonstrate Data
  Interchange, Dynamic Discovery and Integration of
  new services, include a Rich Client with no
  integration bottleneck, and would use a browser
  and standard plug-ins.

3.9 Geospatial One-Stop

• Quick Overview
• In the context of Geospatial One-Stop, a Portal
  is an online access point to a collection of
  geospatial data.
• The Portal does not store or maintain the data
  rather, the data are distributed in many servers
  nationwide.
• Each server is maintained by the agency or
  organization that is responsible for the data in
  the server.
• For example, the federal government might
  maintain a server providing interstate highway
  data, a state might serve data about the highways
  under its jurisdiction, and a city might serve
  urban street data.
• A user should be able to view a map including
  roads from all of these jurisdictions
  simultaneously, letting the Portal automatically
  contact the necessary servers and combine the
  data.
• Furthermore, the user should be able to view
  detailed documentation about the data and its
  provenance(s) if desired.
• Geospatial One-Stop Portal based on open
  standards and specifications that are defined
  collaboratively by a variety of stakeholders, are
  freely published, and are able to be implemented
  by any vendor or organization.
