Municipal Parks are public lands set aside for recreation purposes or to protect natural and cultural environments. We are no longer updating this data. It is best suited for historical research and analysis.

The Ontario Railway Network (ORWN) is seven data classes that use the federal GEOBASE standard for the National Railway Network (NRWN) geospatial data. The seven data classes include: * track * crossing * junctions * marker posts * structure lines * structure points * stations Although the ORWN...

This dataset was created to: * better understand the state of the shoreline * track changes over time * identify priority areas for restoration The dataset provides important information for fish and wildlife habitat assessments. This includes identification of significant fish and wildlife areas...

Statistics include the flood magnitude with the following recurrence intervals: * 1:2 years * 1:2.33 years * 1: 5 years * 1:10 years * 1:20 years * 1:25 years * 1:50 years * 1:100 years * 1:200 years * 1: 500 years These flood statistics can be used for applications such as floodplain delineation...

This spatial dataset represents the boundaries of the areas of responsibility for aggregate inspectors working on behalf of the Ministry of Natural Resources and Forestry. In southern Ontario, inspectors may use various criteria to determine their area of responsibility, including: * geographic...

The Lake Simcoe lake monitoring program provides measurements of chemical and physical water quality limits such as total phosphorus, nitrogen, chlorophyll a, pH, alkalinity, conductivity, dissolved organic and inorganic carbon, silica, other ions, water transparency, temperature and dissolved...

This data contains an Index identifying Ontario Base Map map tiles. Eastern and Southern Ontario is covered at a scale of 1:10,000. Northern Ontario is covered at a scale of 1:20,000. We are no longer updating this data. It is best suited for historical research and analysis. This product...

The Ontario Digital Surface Model (DSM) (Lidar-Derived) Land Information Ontario dataset is a raster product that provides a representation of both surface and ground features derived from a classified lidar point cloud. A DSM is the highest reflective surface of features captured by the sensor....

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...

The Provincial Groundwater Monitoring Network (PGMN) datasets report on ambient (baseline) groundwater level and chemistry conditions. Groundwater monitoring map

Many geometrical schemes - or map projections - are used to represent the curved surface of the Earth on map sheets. Canada uses the Universal Transverse Mercator (UTM) system. It is called transverse because the strips run north-south rather than east-west along the equator. This data class...

Get data on the results of a community led planning process to sustain the natural environment in Prince Edward County and neighbouring communities. This dataset represents the results of a community led planning process to sustain the natural environment across the landscape. A collaborative...

This dataset represents the locations of licenced and permitted pits and quarries regulated by the Ministry of Natural Resources and Forestry under the Aggregate Resources Act, R.S.O. 1990. Aggregate site data has been divided into active and inactive sites. Active sites may be further subdivided...

The dataset identifies the location and types of ANSIs that are commonly used in maps for resource management purposes. Official LIO title: ANSI [ANSIs]: Areas of Natural and Scientific Interest [ANSI]: Areas of Natural and Scientific Interest

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 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...

The attribute table included in the dataset provides some limited metadata information that is specific to each lake. This includes the: * survey year * survey method * original map scale This dataset should be used for discovery of Bathymetry data. It provides no bathymetric information, but...

Fisheries Management Zones have replaced former Fishing Divisions and are the geographic basis for managing, monitoring, assessing and regulating recreational fisheries for a majority of lakes and streams in a zone. Each zone is based on angler usage and ecological/geographic patterns such as...

To identify the Greenbelt Area as defined by the Greenbelt Act, 2005. The outer boundaries of Greenbelt area includes the lands within: * Niagara Escarpment Plan * Oak Ridges Moraine Conservation Plan * Lands designated as Protected Countryside * Lands designated as Urban River Valley

The Ministry of Natural Resources and Forestry defines ecological units on the basis of bedrock, climate (temperature, precipitation), physiography(soils, slope, aspect) and corresponding vegetation. This enhances their compatibility with national and continental classification systems. The ELC...
