The OHN is a provincial medium scale originating from data with regional scales of 1: 10,000 in Southern Ontario, 1: 20,000 in Northern Ontario and 1: 50,000 in the Far North. The shoreline is taken from the OHN - Waterbody data class. This data is used for cartographic purposes and web mapping...

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.

The Baseline hydrology statistics (stream flow regime) in the Southwestern Hudson Bay and Nelson River watershed systems were produced for the Water Survey of Canada's HYDAT database. These baseline statistics provide information on the water quantity at each Water Survey Canada gauge location ....

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,...

The Ontario Radar DSM has the following features: * source data: 1 arc second spaceborne C-Band Interferometric Synthetic Aperture Radar (IFSAR) data * MNR Lambert Conformal Conic Projection * vertical datum in both EGM96 and CGVD28, separately * elevation value: floating * local Polynomial...

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...

This dataset combines: * Far North Land Cover * Southern Ontario Land Resource Information System * Provincial Land Cover 2000 Edition While each of these source products has different pixel resolutions, projections and classifications, the combined OLCC data set is a standardized product. It has...

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.

Data set contains geographical referencing information like: * type of feature or place * location coordinates * geographic township * municipal and map references Also contains places and background information behind their official naming like: * name status * naming date * name origin * naming...

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...

Companies or organizations who take over 50,000 litres of water/day from a lake, river, stream or groundwater source, must obtain a Permit to Take Water from the Ministry of the Environment -with a few exceptions. Permit holders are legally required to record how much water they take each day....

This dataset contains manmade linear features in a transportation network, such as bridges and railway tunnels. It does not include roads. The linear features included are: * aerial cable ways * railway bridges * roadway bridges * railway and road bridges * pedestrian/cycle bridges * railway...

This spatial dataset contains a summary of fishing regulations and fish sanctuary descriptions. The data includes information on: * species catch and possession limits * size limits * seasons and close times * fish sanctuaries * bait and gear restrictions * regulations for specific fisheries...

NGO Nature Reserves are polygon features describing lands held by nature trusts and other non-government agencies for the purpose of nature conservation. We are no longer updating this data. It is best suited for historical research and analysis. This product requires the use of GIS software....

This layer is derived from data provided from Nav Canada. Where possible, it is spatially aligned with Ontario land parcel layers. Data is continually updated. This layer should not be used for navigation purposes. Official LIO title: Airport Official

This information is used  to manage oil and gas rights on offshore Crown lands in Ontario. A grid system of blocks and tracts is used to divide the area. 1 block =  5 minute longitude by 5 minute latitude numbered area. 1 tract =  1 minute longitude by 1 minute latitude area, assigned by letters...

Ontario Integrated Hydrology (OIH) data is used to generate watersheds and support provincial-scale hydrology applications including: * watershed generation * hydrologic modelling * watercourse network analysis Four key datasets are represented in each data package: * stream network (Enhanced...

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 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.
