COG grid

[Harvey Perkins <>]

Alastair (et al),

Details of the COG grid system are given in the ABR each year (see Canberra bird Notes 30(1); p 1 for description and p 61 for map). If brief, grids are of 2.5 minutes of both lat and long, between 34:45:00 and 36:00:00 S (1-30) and 148:40:00 and 149:45:00 E (A-Z). The datum used can be either AGD(84/66) or WGS84/GDA, (preferably the latter to be more with the times) but it is important to specify when submitting records which datum was used.

There is a large (1:100,000) map of the COG area, with grids marked clearly on it, available at monthly meetings for members to consult.
