Ontario Land Information Infrastructure

Ontario Land Information Infrastructure

• Realizing the benefits of quality geospatial
  data in Ontario

2
Presentation Overview

• Introduction
• Components of Ontario Land Information
  Infrastructure
• Current Future CGDI related activities

3
Introduction

• Land information is a strategic resource and the
  fuel for a wide range activities
• There is a growing expectation that data will be
  readily available, especially through the
  Internet
• The federal and provincial governments are moving
  away from large data production efforts
• Local geospatial data sets are typically
  non-standardized, poorly documented, rarely
  publicized and relatively inaccessible. Such
  data are difficult to integrate, share and
  maintain

4
Introduction

• The Land Information Ontario project created an
  Ontario Land Information Infrastructure to share
  geospatial data
• OLII benefits the province and its communities
  through
• Increased data quality by integrating Ontarios
  land information
• Cost avoidance by using standardized data and
  common tools
• Better decisions through improved access to
  geospatial information
• Economic growth and enhanced international
  competitiveness through ready access to low-cost
  geospatial data

The LIO Vision
Ontarios Land Information is well-managed,
accessible, integratable, and affordable

Emergency Management and GIS

• According to an IBM white paper, the response to
  9-11, while heroic and impressive, was hampered
  at the start because information was stored in
  eight different New York City public sector
  databases that collectively used five different
  IT storage formats. If the capability had existed
  to query all those databases and visualize
  information with one map, it could have
  significantly reduced the time needed to make
  decisions. IBM Government Solutions white

  intelligence data in a new way

Ontario Land Information WarehouseApplications,
Services and Tools
8
Sharing DataWarehouse and Directory

• Metadata Directory

• Warehouse

• Internet Browsing

• Publishing/Subscribing

• Security

• Other Services

9
Warehouse and Directory
Ontario Land Information Directory (OLID)

• Acts as a library catalogue with searching
  mechanism
• Data from public and private sources
• Metadata maintained by custodians
• Compatible with other Metadata directories via
  international standards (Z39.50)
• References spatial data and non-spatial
  data

10
Warehouse and Directory
Ontario Land Information Warehouse (OLIW)

• Central repository and distribution hub, of
  geospatial data
• Supports viewing the data, as well as
  distribution of the data
• Supports standard data and integrates it
• Documents and distributes unstructured data

11
Warehouse and Directory
Internet Browsing

• http//www.lio.mnr.gov.on.ca

• Browsing access is via the warehouse browser
• Users view data by theme
• Customized applications meet specific business
  needs
• e.g. MMAH one-window application
• Breeding Bird Atlas
• ERMES

12
Typical users look at the data through a custom
Viewer
13
Data is shown by themes, such as topographic
features
14
Warehouse and Directory
Publishing and Subscribing

• Stable input/output mechanisms are in place to
  support data maintenance
• Accessed via the internet
• Authorized users publish or subscribe to data for
  specific geographic areas

15
Warehouse and Directory
Publishing and Subscribing (contd)

• Data are distributed in a variety of spatial
  formats
• e.g. Shapefiles, Coverages
• Spatial data maintained as geographic, NAD83
• Tabular format is SNIF (comma delimited ASCII)
  other formats under analysis (GML, others?)
• NRVIS exports compatible with warehouse
  publication format

16
Warehouse and Directory
Publishing and Subscribing (contd)

• Data less than 10 mb will be FTPed to clients
• Larger datasets will be cut to CD
• Users can query the status of their extraction
  requests
• Both applications support full datasets or
  changes only from last post/extract
• Datasets can be integrated into the warehouse
  format, or packaged

17
MNR publishes Geographic Townships
MNDM subscribes, and gets the Geographic
Townships layer
MNDM uses Townships to create their Claims
coverage

And publishes the Claims coverage back to the
warehouse
Through Subscription, MNR can obtain the Claims
coverage and use it when editing Park Boundaries
18
Warehouse and Directory
Security

• Specific levels of access to each data set based
  on permission granted by data set owner
• By default respects FIPPA requirements -
  exceptions are supported for individual and/or
  sensitive data where approved

19
Warehouse and Directory
Security

• Default Data Privileges
• Full (All spatial objects and all attributes, no
  personal information, no sensitive objects)
• Sub-set (All spatial objects and a subset of
  attributes)
• Graphics (Spatial objects only)
• Exceptions Upgrade/Downgrade
• Defined geographic extent
• Personal Information
• Sensitive objects

20
Warehouse and Directory
Web Services - OGC WMS

• Access to data via a Web Mapping Service
• Non-proprietary display mechanism
• Can combine data with other sources via a
  cascading map server or other application
• OGC compliant (Open GIS Consortium) spec
  available at www.opengis.org

21
Warehouse and Directory
Web Services - GeoLocator

• Access to spatial functionality via the
  GeoLocator tool from traditional systems
• Provides georeferencing of point data based on a
  variety of criteria (e.g. postal code, settlement
  name)
• Flexible design - Can be called interactively or
  via a batch process
• Future services to be built based on business
  needs

Warehouse and Directory

• Improved performance reliability through
  migration to iServ, others
• Integration with Ontario Road Network
• Integration with new Land Parcel
• OLID Updates (Z39.50, Oracle upgrade, functional
  enhancements)
• Integration with other applications (WRIP, DFOSS,
  FI Portal, Superbuild, others)

  (part of GeoBase), creating an Ontario version -
  the Ontario Road Network (ORN)
• Integral part of the requirements phases and data
  modelling processes
• Z39.50 capability on our metadata server
