Film/Digital Series is a combination of letters and numbers uniquely identifying each film roll or sequences of photographs taken with a digital camera.
ANTC and CASC denote coloured film, ANT and CAS denote black and white film and ANTIR denotes infra red film.
M10-15 is an example of a film series for the Operation Highjump photographs where 10 is the Mission Number and 15 is the Roll Number.
ANTD denotes photographs taken with a digital camera.
Run is the number of the flight line in a film series or digital series along which individual frames were taken. There are usually multiple runs per film.
Height is the flying height above sea level.
In the majority of cases, only the flight lines have values for this attribute. However, in a small number of cases where the run was carried out at varying heights, the flying height was recorded for each photograph. In these cases the average flying height to the nearest 50 metres was attributed to the flight line.
Comments are additional notes.
Dataset id, a dataset identifier, is a number identifying the dataset to which the data belongs. This number can be used to search for information about the dataset. The information includes who took the photography. Some values of this attribute have yet to be populated.
Sometimes within a dataset there are subsets of data with different data quality (eg different positional accuracy). Where this is known, these subsets have been given different Quality information numbers. This number can be used to search for data quality information.
To search using Dataset IDs or quality information numbers, go to the 'Search datasets & quality' tab at Maps, charts and geographic information -> SCAR Feature Catalogue.
Box number identifies the box in which prints of the photos are stored at the Australian Government Antarctic Division. Prints of many, but not all, of the photographs are available for viewing at the Data Centre. For further information contact the Data Centre's Map Curator.
Attributes of photo centres only
Frame is the frame number of a photograph. There are multiple frames associated with each run.
Latitude and longitude specify the location of a photo centre.
Positive (Yes or No) indicates that a positive film of the photograph exists in the Data Centre archives. Positive means the image is the same colour and geometry as the original scene photographed. The positive film is the film exposed to capture the photograph.
Negative (Yes or No) indicates that a negative film of the photograph exists in the Data Centre archives. Negative means the image is reversed in colour and geometry from the original scene photographed.
Diapositive (Yes or No) indicates that a positive film has been made from the negative. That is, it is not the original film that was exposed to capture the image. Diapositives are stored in the Data Centre archives.
Print indicates that the Data Centre has a print of the photograph.
Scanned (Yes or No) indicates whether the Data Centre has a digital copy of the photograph as Jpeg or Tif format. Scanning is done from prints unless indicated otherwise in the Comments field. Photographs are scanned on a needs basis. About 14% of the photographs had been scanned as at May 2005.
Orthophoto indicates that the Data Centre has an orthophoto created from the photograph or photographs. The orthophoto looks similar to the photograph but image displacements due to photographic tilt and relief have been removed.
Attributes of flight lines only
Date is the date on which the photographs were taken.
Camera is the type of camera used for the vertical photography.
Camera oblique is the type of camera used for the oblique photography.
Geographic area describes the area in which the run was flown.
Start frame left is the number of the first photograph on the run, taken obliquely to the left.
End frame left is the number of the last photograph on the run, taken obliquely to the left.
Start frame vertical is the number of the first photograph on the run, taken vertically.
End frame vertical is the number of the last photograph on the run, taken vertically.
Start frame right is the number of the first photograph on the run, taken obliquely to the right.
End frame right is the number of the last photograph on the run, taken obliquely to the right.
Film type describes the type of film used.
Film colour indicates whether the run consists of black and white photographs or colour photographs.
Format for film photography is the dimensions of a frame on the film and for digital photography it is the dimensions of the image sensor.
Focal length left is the focal length of the camera used for the oblique photography to the left.
Focal length vertical is the focal length of the camera used for the vertical photography.
Focal length right is the focal length of the camera used for the oblique photography to the right.
Camera position distinguishes between aerial photography and terrestrial photography. Aerial photography is taken from an aircraft. Terrestrial photography is taken from the Earth's surface.
