A borehole is a general term for any narrow shaft drilled in the ground, either vertically or horizontally. A borehole may be constructed for many different purposes, including: * extraction of water or fluid (e.g., oil) or gases (e.g., natural gas or methane) * for a geotechnical investigation *...

A "contaminant attenuation zone" is a three-dimensional zone that is, * located on land adjacent to a landfilling site, * in the subservice or extends into the subsurface, and * is used or is intended to be used for the attenuation of contaminants from the landfilling site to levels that will not...

A tank is an above ground container that holds either petroleum or water. This data is no longer being updated. It is best suited for historical research and analysis.

This dataset contains linear features constructed by beavers. The linear features are captured to scale on: * single line rivers * lakes * double line rivers We are no longer updating this data. It is best suited for historical research and analysis.

Get data on the results of a community led planning process to sustain the natural environment for the Kawartha Lakes region. This dataset represents the results of a community led planning process to sustain the natural environment across the landscape. A collaborative team of individuals...

Conservation Authority Administrative Areas are lands under the jurisdiction of a Conservation Authority. Instructions for downloading this dataset: * select the link below and scroll down the metadata record page until you find Transfer Options in the Distribution Information section * select...

This historic dataset delineates valley segments based on a number of different natural features. The data applies to valley segments on the Ontario side of the Great Lakes. ALIS has also been incorporated into the Aquatic Ecosystem Classification: Great Lakes Basin and Wetlands Data Class and...

Data has been collected primarily using a depth measurement device, such as an echo-sounder, in combination with a GPS for horizontal positioning. Other survey methods, such as bathymetric LiDAR may also have been used. The survey method used in each body of water is shown in the Bathymetry...

This new data class brings over data from the Waste Management Information System (WMIS), which is an MS Access based database used by MNR to track Waste Management Sites. This was married with the spatial data from Waste Disposal Sites where possible Different Waste Disposal Site types collected...

Designated gas storage areas are land areas designated by the Ontario Energy Board that contain geological formations used for subsurface storage of natural gas. Instructions for downloading this dataset: * select the link below and scroll down the metadata record page until you find Transfer...

This dataset consists of man-made point features in a transportation network. Transport point features include: * Culvert Railway Symbolized - a enclosed drain under a railway * Culvert Roadway Symbolized - an enclosed drain under a roadway * Turntable Railway - a rotatable platform with a track,...

Shows areas where forest insect pests have damaged or killed trees by defoliation, foliage mining and wood boring. Tree mortality rarely occurs as the result of one year's infestation, but from the result of several consecutive years of infestation and other contributing factors affecting...

Ontario's recreational fishing regulations are based on 20 Fisheries Management Zones. This map outlines the "border waters area" in Zone 5. The layer and the resulting map were created by the Office of the Surveyor General of Ontario. Instructions for downloading this dataset: * select the link...

The dataset represents prominent linear (man-made or natural) features including: * cliffs * dykes * fences * walls * hedgerows * feature outlines * racetrack centre lines * racetrack edges We are no longer updating this data. It is best suited for historical research and analysis.

Bathymetry line data was collected to assess fish habitat in Ontario. Spot depths (bathymetry points) were used to measure the depth contours, which function like isobars to show lines of constant depth. Their density and positional accuracies vary depending on the survey style and parameters....

The Digital Elevation Model (DEM) data is organized into 20km x 20km tiles with a spatial resolution of 5m. This data is intended to be used for pre-engineering survey and design as well as the production of planimetric mapping at differing accuracies. This data is intended for GIS and remote...

This dataset contains miscellaneous point features including: * mine head frames * cadastral iron bar (a type of survey monument) * historical monuments * horizontal control monuments * mile posts * smoke stacks We are no longer updating this data. It is best suited for historical research and...

Concentration levels from soil sampled in urban and rural parklands in the province. Data includes: * station name and location (rounded to 1 km precision) * sample date * results for 35 inorganics (1991) * results for 8 volatile organic compounds (2009)
