GeoWarehouse Product Overview
  • The GeoWarehouse online service provides land
    information resources and applications for
    appraisers, realtors, land surveyors,
    environmental consultants, property tax
    consultants, financial institutions and other
    land professionals.
  • GeoWarehouse users have access to both Land
    Registry and Mapping information packaged
    specifically for professional user groups and
    industries. This service provides a wide range of
    reports that are designed to simplify information
    gathering tasks.
  • Information contained in the GeoWarehouse online
    service is updated regularly from the POLARIS
    database, the automated land ownership records
    management system for the Province of Ontario.
  • GeoWarehouse has been a successful product for
    Teranet which was launched in 2001 and now
    serving close to 50,000 users in various markets
    and industries.

GeoWarehouse Redesign - Overview
  • Over time we have added features and
    functionality to the application leveraging the
    infrastructure and interface that existed in 2001
  • 3rd party value added services has been the main
    focus of expansion of GeoWarehouse in the last
    few years
  • Core functionality and enhancements to Teranet
    modules in GeoWarehouse has remained fairly
    static
  • New Mapping and GIS websites are coming online
    and the old GeoWarehouse was outdated and
    required change to keep up with the market
  • Teranet investing in the future of GeoWarehouse
    by re-designing the application in Spring 2008 to
    better serve our customers today and to build a
    versatile robust environment for tomorrow.

GeoWarehouse Project Challenges
  • GeoWarehouse is a web application which has pros
    and cons
  • Mapping usage is likely to increase 10 fold from
    current system
  • Need to link to internal / external data sets but
    make it seamless for the end user
  • Users are not GIS users they require a simple
    and intuitive interface
  • Training and user adoption is key to the success
    of the system but many users are unwilling / not
    receptive to changes
  • Some of the technology being used is unproven for
    large scale deployments
  • Need to maintain privacy and other regulatory
    requirements
  • Coordinate with multiple internal departments as
    well as partners to work in parallel
  • A map is worth a thousand words

12
Biggest Challenge! User Migration
  • Migration and introduction of new site is a
    nightmare no matter how you deal with it
  • Phased in migration over 1 month timeframe
  • Operation of dual environments to allow users to
    migrate themselves
  • Key Components to help manage
  • Interface needs to be simple and intuitive
  • Site needs to fit within workflow and make
    things easier
  • Site needed to flow seamless between property /
    neighbourhood data sets and allow user to look at
    a property in many different ways
  • Data can be interpreted in many ways
    presentation must be clear and easy to understand
    visualization where possible
  • Majority of users are not computer people
  • Training both online, in person and through
    documentation and help at the time it is needed
    is available.

Key Features of Redesign and the Power of Spatial
  • Map Centric interface utilizing a Map viewer
    (Virtual Earth)
  • Utilize Commercially available Ortho Imagery and
    Road Maps
  • Access to Pictometry (Birds Eye) imagery
  • Simple Familiar Interface realtor.ca / mls.ca
  • Creation of a Map Tiling service for Ontario
    Parcel data to be used by the Map Viewer
  • Needed to create tiles of varying map scales of
    parcel data (both assessment and ownership) for
    the Province over 300 Million
  • Needed daily update and publishing (change
    detection and tile re-generation)
  • Integration of MPAC report directly into
    GeoWarehouse for single view of property
    information
  • Using a spatial lookup process to generate PIN /
    ARN correlations
  • Use map functionality to Get ARN and associated
    information

14
Key Features of Redesign and the Power of Spatial
  • iLookabout imagery linked to PINs to show the
    Property from Street View
  • Using parcel data and coordinates of images a
    correlation process was developed to link PINs to
    Images.
  • Privacy was an issue to deal with
  • Generation 5 demographic data elements
  • Summarized in tables and graphs
  • Correlated using address data (postal code) and
    aggregation to minimum of 25 households
  • Zoom2IT Plus
  • Provides access to larger geographic coverage and
    currency than what is available commercially
  • Ability to purchase aerial photos
