The digital elevation models (DEM) are 2 m resolution raster elevation products that were generated from the Ontario Classified Point Cloud (Imagery-Derived) data. The point clouds were created via a pixel-autocorrelation process from the stereo aerial photography of the Land Information Ontario...

This dataset was created to provide land use information on the Oak Ridges Moraine and is the basis for Ontario Regulation 140/02. The data was digitized at 1:10,000 or better using 0.5 metre air photos, MNR, DMTI, Upper and Lower-tier Official Plans and digital vector layers.

The flood magnitude statistics can be used for applications such as flood plain delineation and design of hydraulic structures. The drought severity statistics can be used for applications such as water abstraction and effluent dilution.

Depicts the internal boundaries of the Niagara Escarpment Plan area. The 7 land use designations are: * escarpment natural area * escarpment protection area * escarpment rural area * minor urban centre * urban area * escarpment recreation area * mineral resource extraction area The land use...

This historic dataset includes data reported under Ontario’s now revoked Emissions Trading Program regulations (O. Reg. 397/01: Emissions Trading and O. Reg. 194/05: Industry Emissions - Nitrogen Oxides and Sulphur Dioxide). The Emissions Trading Program ended in February 2021, as the program...

A feature is a representation of a real world object, such as a lake, stream, dam or rapid. There are three hydrographic feature classes:  points, lines and polys. All may impede or be hazardous to waterflow and/or navigation on a watercourse or waterbody. This data shows natural and manmade...

The air monitoring stations measure up to 6 common pollutants like: * ground-level ozone * fine particulate matter * nitrogen dioxide * carbon monoxide * sulphur dioxide * total reduced sulphur compounds The Ministry of the Environment, Conservation and Parks continually monitors air quality...

This data was produced in 1999 by rationalizing a 48-class database into 28 distinct classes. The original database was derived from digital, multispectral Landsat Thematic Mapper data recorded between 1986 and 1997, with most of the satellite data frames recorded in the early 1990s. The...

The purpose of this dataset is to depict the boundaries of the Niagara Escarpment Plan. The outer boundary of the area covered by the Niagara Escarpment Plan is fixed and inflexible. It can only be changed by a plan amendment. It is formed by a combination of features like: * roads * railways *...

The OPS has adopted these boundaries for administrative and functional purposes which will facilitate enterprise initiatives and enhance customer service. We are no longer updating this data. It is best suited for historical research and analysis.

Shows areas where the health and prevalence of caribou can be linked to the attributes of the land that supports them. Ontario's Woodland Caribou Recovery Strategy (2008) provides advice and recommendations on the approaches needed for the recovery of Woodland Caribou. The strategy recommends the...

Includes: * contour land * contour land approximate * contour land auxiliary/interpolated * contour land depression In southern Ontario the contour interval is 5 meters. In the near north the contour interval is 10 meters. In the Far North the contour interval depends on the information source....

This dataset provides information submitted by well contractors as prescribed by Regulation 903, and is stored in the Water Well Information System (WWIS). Spatial information for all of the well records reported in Ontario are also provided. Well record map *[WWIS]: Water Well Information System...

The Niagara Escarpment Special Policy Area is comprised of the North Aldershot Policy Area and the Waterdown Policy Area. More information

Watercourses are line features - natural or manmade - that represent the location of flowing surface water. This product requires the use of GIS software. *[GIS]: geographic information system
