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 data provides core information on truck travel and commodity flows on the provincial highway network and other significant truck corridors. It provide ESAL information for all provincial highways and other significant truck corridors by road segment. *[ESAL]: Equivalent Single Axle Load

A spot height identifies the elevation (z value) above sea level of natural and man-made geographic features. It includes: * spot heights * vertical control points * water level/lake elevations Instructions for downloading this dataset: * select the link below and scroll down the metadata record...

Bathymetry is the measurement of water depth in lakes. From the 1940s to the 1990s, the Ministry of Natural Resources and Forestry produced bathymetry maps for over 11,000 lakes across Ontario. The data can be used by the general public and GIS specialists for: * climate change modelling * fish...

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 data provides modelled average hourly traffic count information by weekday/weekend. Commercial vehicles and autos data is collected at Commercial Vehicle Survey locations (latitude/longitude) on provincial highways at border crossings. This data is used to model hourly estimates of passenger...

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 dataset is used to: * assess biodiversity levels * define seed zones * map ecosystem types * set targets for the identification of natural heritage systems

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.

This boundary is used in the management of watershed-based planning by the Lake Simcoe Region Conservation Authority (LSRCA). It is used to support the Lake Simcoe Protection Act (LSPA). Instructions for downloading this dataset: * select the link below and scroll down the metadata record page...

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...

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 Ontario in-filled climate data collection includes information from 339 monitoring stations maintained by the Meteorological Service of Canada. Historical climate data commonly has missing hourly and daily records due to equipment malfunctions, temporary site maintenance or other reasons....

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...
