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...

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...

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 locations of wells that have been drilled for oil production, gas or salt resources or for underground storage of hydrocarbons. This data can be used for land use and resource management, emergency management, as well as compliance and enforcement in the petroleum industry. The Data is...

General information on the location of towns and villages (settlement areas) in the countryside areas protected by Greenbelt plan. For precise boundaries and locations of settlement areas, the appropriate municipality should be consulted.

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....

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...

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...

The spatial record for all the province's geographic areas affected by provincial level, area-specific land use policy. This layer may contain geometry from the: * provincial parks-regulated layer * conservation reserves-regulated layer * natural heritage values area layer *  wilderness areas...

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
