Forest cover maps follow the British Columbia Geographical System (BCGS) of mapping. The cartographic framework for this mapping is the Universal Transverse Mercator (UTM) coordinate system. This system is based on the North American Datum 1927 (NAD27) or the North American Datum 1983 (NAD83). Each mapsheet is precisely 12 minutes of latitude wide by 6 minutes of longitude high. The NAD conversion project that was underway for the last couple of years, is now complete. |

The Okanagan Land Resource Management Plan (LRMP) is a higher level plan that will determine Resource Management Zones (RMZ's) across the Okanagan Timber Supply Area (TSA). To facilitate the process of creating the RMZ's a number of maps were created which display the various resource values in this area of the province which includes Salmon Arm, Vernon and Penticton Forest Districts. These maps are available at 1:300,000 scale

In 1995, the Okanagan Shuswap Forest District flew 1:50 000 black and white photography covering the southern end of the District. From this photography, orthorectified and mosaic images were created. The imagery has a resolution of approximately 1 meter pixel with each file created as a single, seamless B.C.G.S. mapsheet, UTM co-ordinates, NAD83 datum.

Colour aerial photography is becoming increasingly available for more areas of the province, particularly in the Okanagan and Cariboo areas. Colour air photos were first taken in 1967. To date there are more than 1500 rolls (flightlines) of colour film.
Black and white aerial photography is available for all of British Columbia at a variety of scales and in some areas, dating back more than fifty years. Most areas of the province are covered by air photos less than ten years old, with large areas covered by small scale (1:60,000 or 1:70,000) photography from 1982-1988. |
