Covering more than a million square kilometers, Ontario has a rich and diverse geography. Land Information Ontario (LIO) manages geographic information for use in maps and Geographic Information Systems (GIS).
LIO has a web-accessible data warehouse that contains more than 250 different layers of geographic data. The data ranges from the location of underground wells to satellite imagery.
More than 2,000 registered users deposit and extract geographic data from the LIO Warehouse. Users include federal government departments, other provincial ministries, municipalities, public health units, conservation authorities, universities and colleges, boards of education and private sector organizations such as utility companies and land developers.
