The data layer identifies areas of disturbance to vegetation including burns, commercial forestry harvesting (cuts), weather events, infrastructure and pest/disease. Instructions for downloading this dataset: Instructions for downloading this dataset: * select the link below and scroll down the...

The locations of the 2 specialty crop areas in the Greenbelt Plan: * the Holland Marsh * Niagara Peninsula Tender Fruit and Grape Lands

Data includes: * The Lake Superior watershed * The Lake Huron watershed * The Lake Erie watershed * The Lake Ontario watershed * The St. Lawrence River watershed

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...

Fish Culture Operation MNR identifies the locations of the Ontario Ministry of Natural Resources (MNR) fish culture stations (or hatcheries) and sub- stations. The data set outlines their property boundaries. This product requires the use of GIS software.

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...

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....

Fire management agreements divide land into 4 areas: * Crown Protection Area (CPA): The Crown is responsible for responding to all fires in the CPA * Municipal Protection Area (MPA): The municipality is responsible for responding in the MPA * Federal Protection Area (FPA): The federal government...

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...

Data covers natural, rural and urban lands in Ecoregions 6E and 7E, current to 2000-2002. This land use inventory supports key provincial initiatives including: * source water protection * natural spaces * biodiversity conservation * state of resources reporting

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...

Fish Habitat Type Data for Ministry of Natural Resources and Forestry's Parry Sound District used for fisheries management.

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.

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...

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.

Bait resources in most of the province are assigned to harvesters through the use of a block system -- 1 harvester per 'bait harvest' area. There are exceptions to the block system (e.g., Lake Erie), where bait is allocated to multiple users fishing the same area.

MNR regions are divided into districts - smaller organizational units - to help manage ministry programs and resources. Extents of the districts were originally compiled by description of: metes and bounds, topographic features, geographic township boundaries, territorial district boundaries,...

This data set shows utility lines that provide services for: * power * water * communications * heating fuel They include: * communication lines/submerged communication lines * hydro lines/submerged hydro lines * natural gas pipelines/submerged natural gas pipelines * water pipelines/submerged...

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.
