This spatial dataset represents the locations of aquatic resource area (ARA) line segments derived from corresponding line features in the Ontario Hydro Network. ARA line segments may represent a portion of a water body or an entire water body (such as a lake, river or stream). Attributes for...

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

An abiotic damage event is a non-biological event -- such as wind or an ice storm -- that has damaged areas of forested land. Abiotic damage event information is mainly used to: * generate summary maps for these events at a general or provincial scale * monitor the extent of damage for forest...

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...

Watercourses are line features - natural or manmade - that represent the location of flowing surface water. This product requires the use of GIS software. *[GIS]: geographic information system

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...
