01 Survey Mapping

An aerial map of the area was obtained through Google Earth (TM). The image dated March 31, 2005 was at the beginning of this study the image with the highest resolution of the area. It is particularly interesting because of the ground detail showing the patches with moss growth, as well as, the distinction between coniferous and deciduous trees in the forested areas. The second image used was a flyby taken during the course of this study on August 31, 2009. The image is of sufficient resolution to allow for a good correspondence between image detail and general field observations of forb/grass distributions and tree families.

Historical aerial maps from 1954 (1954 NEC 4321 25 245 & 246) until 1974 (1974 NEC-5 L25 235 & 236) were kindly accessed from the Halton Conservation Authority. Aerial views for the years 1987 and 1994[1] were obtained from the Halton Region GIS and Data Management department[i] [ii]. Aerial views of the area for 2004, 2005, 2007 and 2009 were obtained from Google EarthJ[iii]
