Wooded Area Coordinate system: 4269 - "NAD83" Abstract: Revision Note: Please note that this dataset has been revised and is available from the Land Information Ontario (LIO) Warehouse. Wooded Area polygons represent the boundaries of woodlands (forests, woodlots, hedgerows, and plantations) in Southern Ontario. The woodland dataset is one of numerous products derived through the implementation of the SOLRIS project. The methodology used in SOLRIS Phase 1 involves updating the NRVIS wooded area (WOODAREA concrete class) data through the interpretation of remotely sensed data including orthophotography, Indian Remote Sensing (IRS) and colour infrared aerial photography. Wooded Area polygons represent the boundaries of woody vegetation (including shrubs) mapped to Ontario Base Mapping standards in Northern Ontario (EcoRegion 5E) and a revised standard to capture more definitive 'treed areas' in Southern Ontario (EcoRegions 6E and 7E). Trees and shrubs in this layer have a minimum of 2 meter height. Supplementary tables can be used and are available for download from the additional documentation section.

  Purpose:

  To depict area covered by trees in the Province of Ontario and allow continuous updates to be made to the dataset. This dataset is often used by those wanting a depiction of treed areas that do not have access to the Provincial Forest Resource Inventory data - eg: Municipalities and non-profit groups not affiliated with monitoring or maintaining the Forest Resource Inventory (FRI).

  SOUTHERN ONTARIO MAPPING STANDARD (EcoRegion 6E and 7E): The Southern Ontario Mapping standard was created through the initial SOLRIS Phase 1 project (2003-2006) and covers EcoRegions 6E and 7E. The standard used to delineated polygons in Southern Ontario is: - Areas with trees > 2 metres in height, and 60 percent canopy coverage with a minimum mapping unit (MMU) of 0.25ha where mapped from orthophotography and 0.5ha where mapped from IRS imagery. - Imagery interpretation at 1:5000 scale - Differentiation between Plantation, Hedgerows and Treed Areas. (WOODED_AREA_TYPE field) - 'Plantations' are interpreted features that meet the treed description and are clearly planted by humans (visible linear geometry) in recent imagery. Horticultural crops such as orchards, tree nurseries and Christmas trees are not considered plantation or even treed but rather cultural features. - 'Hedgerows' are interpreted features that meet the treed description (including MMU) and are a linear feature no wider than 30 metres with a minimum width of 10 meters. 'Treed Areas' is the default - 'Other' should be used to identify features captured through the OBM mapping process or other features that have comments associated that may result in the necessity to query at a later date. ONTARIO BASE MAPPING STANDARD (EcoRegion 5E) Northern Ontario OBM polygons were captured using imagery from (1978-1996). This standard was highly generalized and did include thickets with canopy cover less than 60 percent as well the incorporation of plantations. Features captured through the older OBM standard are flagged as 'Other' within the WOODED_AREA_TYPE field and will also be flagged as 'OBM polygons' in the TYPE_OTHER_DESCR field.

  
  

  Process step:

  Data is maintained through NRVIS. Imagery used to interpret features in Southern Ontario through the SOLRIS Project was from 1998 through 2002. Where resources and improved imagery exists, features may have been captured beyond this standard. Please note that swamps were captured as 'Treed Areas' as they meet the standard - analysis can derive swamp communities.

  Features updated in Southern Ontario between 2003-2006 was produced using summer IRS Satellite imagery (1998-2002), summer IKONOS Satellite imagery (2001-2002), spring orthophotography (2002-2003) and spring/summer infrared photography (1994-2003). This dataset will continue to be modified. Clients should contact their local MNR district regarding 'Fitness for Use' and currency/accuracy provisions.

  IRS Pansharpened Satellite Imagery: Indian Remote Sensing (IRS) pansharpened satellite imagery. This imagery was acquired between the spring of 1998 and the fall of 2002. The currency of this imagery varies by individual image used. Data collected from 01/01/1998 to 01/01/2002. The IRS pansharpened satellite imagery is a false colour product derived by combining low resolution multispectral satellite imagery with high resolution panchromatic satellite imagery. This process provides a more detailed colour image. IRS panchromatic imagery was combined with either multispectral IRS imagery or LANDSAT-7 ETM multispectral imagery, depending on available data and date matching preferences. The near infrared, red and green bands of the multispectral imagery were used in order to create a false colour composite image which is preferred for mapping vegetation. Ground Sampling Distance: 5 meters

  Orthophotography: Digital orthorectified aerial photography. Data collected from 01/01/2000 to 30/06/2003. Orthorectified and digitally enhanced aerial photography. Black and white and true colour orthophotography acquired between 2000 and 2003, depending on the area being mapped. Ground Sampling Distance: 0.20 - 0.50 meters.

  Colour Infrared Air Photos: Aerial Photography Data collected from 01/01/1994 to 01/01/2003 Data collected from 01/01/1994 to 01/01/2003. Southern Ontario colour infrared aerial photography (CIR) was derived through the acquisition of aerial photography throughout southern Ontario during the spring and summer months from 1994 to 2003. Ground Sampling Distance: 0.50 meters.

  Ontario Basic Mapping Program: Mapping produced using 1:30000 and 1:50000 aerial photography. Digital data produced from the OBM program was generated based on interpreted aerial photography captured between 1977 and 1996.
