Notes on information formats given with each image:
Latitude, Longitude and Altitude:
In most cases this information is derived from a Global Positioning
System (GPS) and is presented within the accuracy limits of the
device employed at the time. Latitude and Longitude are normally
presented in degrees and minutes to 3 decimal places.
Where Latitude and Longitude have been derived from external sources
(ie. contributors and from data bases), the format is more likely
to be in degrees, minutes and seconds.
These, and the former, are regarded as accurate to within a few
feet/metres unless the word "approx". appears next to the positional
information. Most photographs taken prior to 2000 will have approximate
positional data.
Image Format:
35mm - indicates that the original image is a 35mm (36 x 24mm transparency)

measuring 6 x 4.5cm; 6 x 6cm or 6 x 7.5cm
LF - indicates that the original is a 10.2 x 12.7cm or larger transparency.
