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) *[GIS]: geographic information system

Get information on research plots for the Guide Effectiveness Monitoring Program This dataset includes ecological information for Guide Effectiveness Monitoring (GEM) Program site locations. The GEM Program evalutes the effectiveness of forest management guides on songbird occupancy rate and community structure. Learn about the procedures and protocols used for this study in the [Centre for Northern Forest Ecosystem Research Technical Report 004: Effectiveness Monitoring of Forest Management Guides](https://www.ontario.ca/page/catalogue-natural-resource-scientific-and-technical-publications).

Prior to January 1, 2008, fishing divisions were administrative units to manage, monitor, assess and regulate recreational fisheries. Each zone was based on angler usage and ecological/geographic patterns. Refer to [Fisheries Management Zone for boundaries after 2008](/dataset/fisheries-management-zone).

The built boundary identifies built-up urban areas across the Greater Golden Horseshoe. It is a fixed line that reflects what was built and on the ground when the Growth Plan came into effect in June 2006. The boundaries are an important implementation and monitoring tool for the Growth Plan for the Greater Golden Horseshoe. The built boundary will allow the province and others to measure intensification and redevelopment within the built-up area, and also allow us to monitor suburban development outside the built-up area. The built boundary was released in its final form on April 2, 2008, along with the methodology used to create it. This product requires the use of GIS software. *[GIS]: geographic information system

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 team of individuals representing governments, stewardship councils, conservation organizations, local industry and private landowners worked together to identify and map natural heritage features and the connections between them. The data package includes: * spatial data * project reports * presentation materials The data has been made available to inform and support: * land use planning and resource management decision-making * strategic priorities for stewardship and restoration projects * priorities for conservation land acquisitions * priorities for inventory programs and research projects

The land cover classes consist of vegetation types (such as forest, wetlands and agricultural crops or pasture) and categories of non-vegetated surface (such as water bodies, bedrock outcrops or settlements). These classes reflect the nature of the land surface rather than actual or potential land use. The 2000 Edition of the Ontario Land Cover Data Base is the Second Edition of this provincial land cover classification. The coverage is derived wholly from Landsat-7 Thematic Mapper (TM) satellite data frames recorded between 1999 and 2002, most from 2000 onward. The Provincial Land Cover (2000) Data Base is divided into 4 individual Universal Transverse Mercator (UTM) grid zone tiles (15, 16, 17, and 18) and is distributed in TIFF format. Documentation is provided with this database in the form of a user's guide and general use caveats. *[TIFF]: Tagged Image File Format *[TM]: Thematic Mapper *[UTM]: Universal Transverse Mercator

Rivers included in this map series include: * Albany * Winisk * Severn * Moose * Ekwana * Attawapiskat The maps display gauging systems such as cost share agreement gauges, Water Survey of Canada gauging stations and Meteorological Survey of Canada Climate stations. Dams, their jurisdictional owners and Far North First Nations communities are included.

Ontario's Crown forest is divided into geographic planning areas, known as forest management units. Most of these units are managed by individual forest companies under a Sustainable Forest License. A forest management unit is identified by an assigned official name (e.g., Black Spruce Forest) and a unique numeric code. Before any forestry activities can take place in a management unit, there must be an approved forest management plan in place for each management unit.

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

These signs serve a variety of purposes ranging from providing general information and safety warnings, to enforcement and land management notices to the general public. Ministry of Natural Resources (MNR) signs are erected to support and enforce such provincial acts as the: * Fish and Wildlife Act * Public Lands Act This product requires the use of geographic information system (GIS) software.
