UTC - Utility and communication networks (utilitiesCommunication) Energy, water and waste systems, and communications infrastructure and services. For example, resources describing hydroelectricity; geothermal, solar, and nuclear sources of energy; water purification and distribution; sewage collection and disposal; electricity and gas distribution; data communication; telecommunication; radio; and communication networks.

A Safety Feature is one of a number of various appliances/appurtenances that have been installed or constructed either alongside or as an integral part of the road infrastructure to reduce the severity or potential of accidents. It is a Point feature

A Drainage Appliance is an apparatus (that has not been described as a culvert), or earth works, designed to facilitate the movement of water in a controlled manner. Drainage Appliance include some appliances/earth works that work in conjunction with culverts. It is a Point feature

Polygon features showing various zones of protection around drinking water system intakes/wellheads. A drinking water system is any domestic system servicing anything other than a single-family dwelling, as defined in the Drinking Water Protection Act. Zone of protection is a broad term that represents a wide variety of areas as they have been delineated in their corresponding report. The methods and processes used to delineate these zones vary based on several factors including, but not limited to, population, vulnerability, hydrologic/hydrogeologic parameters, etc. For the use of this dataset, the term Protection Zone means that protection measures should be considered and/or implemented in these areas due to the importance of these areas supplying drinking water to their water system users. Protection Zone does not mean that protection measures have been implemented in these areas, nor that protection measures are not required beyond the boundary of these areas. This is one of three Drinking Water Sources datasets (along with the DWS - Intakes/Wellheads points dataset, and DWS - Source Areas polygons dataset). Note: these polygons have unique Protection Zone IDs used to relate them to the Intakes/Wellhead points.

A Storm Sewer is an enclosed system of pipes or drains that divert water away from the road and/or right of way. Also includes culverts that run under enclosed ditches. It is a Linear feature

A feature is a representation of a real world object, such as a lake, stream, dam or rapid. There are three hydrographic feature classes:  points, lines and polys.   All may impede or be hazardous to waterflow and/or navigation on a watercourse or waterbody. This data shows natural and manmade poly features.  Examples include: * break walls * dams * rapids * shipwrecks [Technical Bulletin: Data migrated to new Ontario Hydro Network (OHN) - Hydrographic Feature Data Classes (PDF)](http://geo2.scholarsportal.info/proxy.html?http:__maps.scholarsportal.info/files/PDFS/public/OGDE/OHN/TB-OHN-PostMigration_101112.pdf)

There are three hydrographic feature classes:  points, lines and polys.   All may impede or be hazardous to waterflow and/or navigation on a watercourse or waterbody. This data shows natural and manmade line features. Examples include: * break walls * dams * waterfalls * lock-gates * rapids * rocks * Sea Lamprey barriers * shipwrecks This product requires the use of geographic information system (GIS) software.

A Culvert is a pipe (less than 3m in diameter) or half-round flume used to transport or drain water under or away from the road and/or right of way. Culverts that are greater than or equal to 3m in diameter are stored in the MoT Bridge Structure Road Dataset. It is a Point feature

A Guardrail is a barrier fastened to the end of a bridge abutment, along the shoulder of a road or between travel lanes of opposing traffic. It is a Linear feature
