Abstract
|
RVCA Woodlands is a polygon feature class derived from the RVCA Landcover dataset and is based on leaf-off ortho-rectified imagery (DRAPE). RVCA Woodlands include Wooded Areas, Treed Swamps, Plantations & Hedgerows.
RVCA’s land cover mapping (1:5000) represents the physical landscape using 8 distinct land cover classes. In addition to a land cover class, an individual feature may be detailed with subclass information (for example, “Wooded Area” as the class and “Plantation” as the subclass). Currently, RVCA’s land cover mapping represents the landscape during 2008, 2014 and 2019/20 within a single dataset. Features representing change about the landscape are attributed with class and subclass information for all three dates, providing a seamless time-series map of the watershed.

Methodology
|
This dataset has been under development since 2009 (Phase 1). As a starting point, legacy provincial mapping (representing a range of historical dates) for transportation, authorized aggregate sites, water, forest, and wetland were assembled into a preclassified map. Updates to this mapping were made using industry standard heads-up digitizing workflows. Interpretations of georeferenced orthoimagery (DRAPE 2008 and 2014) helped to update legacy mapping and capture additional classes (settled areas, meadow/thicket, and crop and pasture). Over a six-year period, RVCA produced up-to-date land cover mapping of its watershed, which represents the leaf-out season of 2008. Phase 2 included updates to the data referencing DRAPE 2014, and Phase 3 DRAPE 2019/20.
