Toronto and Region Conservation Authority

Description:

Since its formation in 1957, the Toronto and Region Conservation Authority has been delivering programs for the management and protection of the watersheds within its jurisdiction.

In April 2008, the Geospatial Centre received vector datasets from the TRCA which cover the municipalities of Toronto, Vaughan, Richmond Hill, Markham, Pickering, Ajax and parts of Uxbridge, Whitchurch-Stouville, Aurora, King, Caledon, Brampton and Mississauga. The fauna and flora layers are very rich in detail.

The datasets provided to the Geospatial Centre include:

TRCA Vector Data
contours (1 metre)	natural cover (forest, meadow, beachbluff, ecological succession, wetland)	waterbodies
fauna (significant species: birds, squirrels, frogs: alder flycatcher, bobolink, etc.)	TRCA properties	boundary water-shed
flora (significant species: woodfern, shagbark hickory, wild ginger, black ash, star-fire, etc.)	vegetation community types (sumac cultural, thicket, willow shrub beach, dry-fresh oak-hardwood deciduous forest)
municipality boundaries	water courses

Spatial Reference and Data Type:

These data sets are available in UTM. zone 17 co-ordinates; horizontal datum is NAD 83. These data are stored as Esri shapefiles. Other data formats can be accommodated, as the Geospatial Centre has access to a number of conversion utilities.

Data Access:

In order to access these data sets, please visit the Geospatial Centre Reference Desk during reference hours. Library reference staff are available to provide further information about these data sets and to deliver data upon request.

Data Manipulation:

There are public workstations in the Geospatial Centre that provide access to both ArcGIS and ArcView software programs, program extensions and data manipulation utilities. Patrons may use the GIS and image processing software in the library to view and manipulate the data. UW faculty, students and staff may copy these data to other media (for example: CD, DVD or Zip disc) for use elsewhere.

Data Output:

This image may be exported from ArcGIS in a choice of bitmapped formats (also known as raster graphics) including JPG, TIFF, GIF, and BMP or in a choice of vector graphics formats including AI, EPS, and SVG. Yet another option is PDF.
