About LIO

WHAT IS LAND INFORMATION ONTARIO?

Land Information Ontario (LIO) is a provincial initiative that supports the province-wide sharing of geographic data. LIO provides centralized access to data through a number of tools and services:

LIO Warehouse
The LIO Warehouse is a web-accessible database that stores geographic data containing almost 30 million land features from across the province. The data ranges from administrative boundaries to transportation arteries to land ownership information to the location of underground wells and satellite imagery. Registered users are assigned a username and password so they can extract data from the LIO Warehouse.

Data Exchange
To access data from LIO’s Warehouse, users must become members of the Ontario Geospatial Data Exchange. The Data Exchange allows organizations to access and share geographic data under a single legal agreement. Membership in the Data Exchange is free and available to a wide variety of organizations.

Data Directory
The Ontario Land Information Directory is a searchable catalogue of the province’s geographic data holdings. Users can create and publish descriptions of their data to the directory so it can be discovered on the Internet.

Internet Mapping
LIO’s Make a Map application allows users to make their own topographic map of any area in the province. Users can select which data layers they want to feature on their map. The application also has the ability to draw on real-time web map services to display geographic data from sources across the world.

In addition to providing these tools and services, LIO manages provincial data sets such as the Ontario Road Network, the Ontario Parcel database and the Ontario Trail Network. LIO also works with partners to acquire high resolution digital imagery across the province.

LIO develops and maintains georeferencing standards and tools to ensure that public sector organizations are consistently referencing their geographic data holdings to a single modern referencing system that is GPS compatible and used by the majority of GIS users.
