Aerial Photos
You may purchase aerial photographs at various resolutions from Alberta Environment and Sustainable Resource Development . Aerial photographs allow you to locate and identify many items on your woodlot such as boundary lines, roads, fields, streams and stands of trees.  Aerial photographs can be in various colors or black & white and can be taken at various times of the year (differing leaf cover).  Aerial photographs are particularly useful for showing water and drainage patterns.

With the use of a steroscope and 'stereo pairs' (photographs on either side of the property) you can view the woodlot in 3-dimension which allows you to see the heights of trees and topography of the land.

Maps
A photocopy of a property map on which the property lines are identified may prove to be very valuable. You will require the legal land location, which may be obtained from the municipal assessment office.
