Data with the following information for large landfills: * landfill capacity * fill rates * estimated remaining capacity * engineering designs * reporting and monitoring details **This dataset was last updated in 2014 and contains out of date information. It has been replaced by the [Ontario landfills](https://data.ontario.ca/dataset/ontario-landfills) dataset.**

Hazardous forest types for wildland fire means forest types assessed as being associated with the risk of high to extreme wildland fire. This data is intended to help inform where further assessment is required and is to be used in conjunction with guidance from the Ministry of Natural Resources and Forestry .

Ministry of Natural Resources (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, etc. Changes to the extent of the districts have been made over time by MNR district offices. This product requires the use of geographic information system (GIS) software.

This dataset shows the boundaries of the province's six fire management zones that existed prior to 2014 in which most forest fires received the same type of response. These management zones were based on: * common forest and forest fire management objectives * land use * density of values at risk * fire load * forest ecology The 2014 Wildland Fire Management Strategy moved from a zone-based approach to one where each wildland fire is assessed and receives an appropriate response according to the circumstances and condition of the fire.

Displays areas regulated as a conservation reserve in order to: * permanently protect representative ecosystems, biodiversity and significant elements of Ontario's natural and cultural heritage * provide opportunities for ecologically sustainable land uses, including traditional outdoor heritage activities and associated economic benefits * allow for scientific research and provide points of reference to support monitoring of ecological change on the broader landscape Official GEO title: Conservation Reserve Regulated

A building is a structure that has a roof and walls and stands more or less permanently in one place. Symbols are used when buildings and structures are permanent landmarks. Symbolized buildings have no side larger than 50 metres for 1:20,000 data or no side larger than 30 metres for 1:10,000 data. Small structures (including buildings less than 50 square metres) are not shown unless they constitute a point of orientation. This product requires the use of geographic information system (GIS) software.

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 * for an environmental site assessment * for mineral exploration * as a pilot hole for installing piers or underground utilities This data contains a continuous log of strata for each borehole as well as for geocolumns. A geocolumn is a collection of information from an examination of exposed substrate, such as in a quarry wall or along a roadway passage.

The Ontario Raw Point Cloud (Imagery-Derived) is elevation point cloud data created from aerial photography from the Geospatial Ontario (GEO) imagery program. It was created using a pixel-autocorrelation process based on aerial photography collected by the imagery contractor for the GEO imagery program. The dataset consists of overlapping tiles in LAZ format and is 6.29 terabytes in size. Tiles are overlapping because the pixel-autocorrelation process extracts elevation values from overlapping stereo photo strips. No classification has been applied to the point cloud, however they are encoded with colour (RGB) values from the source photography. This data is for geospatial tech specialists, and is used by government, municipalities, conservation authorities and the private sector for land use planning and environmental analysis. __Related data__ For a product in non-overlapping tiles with a ground classification applied, see the [Ontario Classified Point Cloud (Imagery-Derived)](https://geohub.lio.gov.on.ca/datasets/febf17330adb4100a22738e1684b5feb). Raster derivatives have been created from the point clouds for some imagery projects. These products may meet your needs and are available for direct download.

The Ontario Radar Digital Surface Model (DSM) has the following features: * source data: 1 arc second spaceborne C-Band Interferometric Synthetic Aperture Radar (IFSAR) data * Ministry of Natural Resources (MNR) Lambert Conformal Conic Projection * vertical datum in both EGM96 and CGVD28, separately * elevation value: floating * local Polynomial Interpolation from vector elevation points * spatial resolution: 30 meter * asurface elevation model This product offers significant advancements in elevation data in the province. [Read the details about these advancements and other technical specifications,](https://geohub.lio.gov.on.ca/maps/mnrf::ontario-radar-digital-surface-model/) including data processing, major spatial characteristics of the Radar DSM, and the steps to generate the Northern Ontario Radar DSM.

This spatial dataset represents the boundaries of areas designated under the [Aggregate Resources Act, R.S.O 1990](https://www.ontario.ca/laws/statute/90a08) where a licence or permit is required for aggregate extraction. Under the Act, all aggregate operations must be licensed on private land or permitted on Crown land.
