Definition of termsObtaining imagery
Satellite imagery is supplied to the Australian Antarctic Data Centre under the following conditions:
- Under no circumstances must the satellite imagery be given to a third party.
- The Data Centre and the company supplying the image must be acknowledged in all papers, posters or books where information sourced from the imagery is used.
To see how imagery should be acknowledged, click on the sensor of the image that you are acknowledging.
- On completion of your research the satellite imagery must be removed from any computer, CD-ROMs, DVDs or other materials where the imagery may be copied to and returned to the the Data Centre.
- The use of the imagery must be restricted to the research that comes under the umbrella of Australian Antarctic Science (AAS) or the Australian Antarctic Division as the imagery is restricted to a single user license.

About space photography
About Space Photography
Three different types of space photography have been acquired from the Soviet space program: MK4, FKA1000 and Kate200.
Space photography has been considered separately from aerial photography due to scale. The scale of space photography varies from 1:300 000 to 1:1 500 000. The scale of the aerial photography varies from 1:3 000 to 1:61 000. As a result of the scale difference, the resolution of the photography also varies and this determines the accuracy to which the data can be interpreted. Below is a summary of the space photography in the Data Centre's archive over the Australian Antarctic Territory (AAT) and the cameras used. SojuzKarta is the name of the distributor and MK4, FKA1000 and Kate200 are the names of the camera.
| Camera | Scale | Focal length | Film format |
|---|---|---|---|
| SojuzKarta MK4 | 1 : 667 000 | 300 mm | 180 mm |
| SojuzKarta FKA1000 | 1 : 300 000 | 1000 mm | 300 mm |
| SojuzKarta Kate200 | 1 : 1 500 000 | 200 mm | 180 mm |
The MK4, FKA1000 and Kate200 are multilens cameras. They have the same basic characteristics as a single lens camera except they have four lenses and expose four photographs simultaneously. Each camera has a film with an emulsion that is sensitive to a different region of the electromagnetic energy spectrum. Three are panchromatic and one is black and white.
These cameras are equipped with a reseau or glass plate with an etched grid. The reseau is imaged on the negative at the instant of exposure. The grid marks allow for the control of film shrinkage or expansion corrections.
Calibration certificates are available for some of the cameras used to produce the Sojuz Kate200 photographs. Calibration certificates are available for the MK4 and FKA1000 photographs.
In 1996 the Kate200 images were scanned at 200dpi. These are available upon request.
Other problems include poor exposure, cloud, Newton rings and to a lesser extent, dust and finger marks. Newton rings are caused by trapped air between the film and the glass. Today this is alleviated by vacuum pumps. The rings appear like a moiré pattern. There are also water marks on the negatives due to careless developing. The Kate200 photographs have the most problems. The corner latitudes and longitudes vary in accuracy, particularly the KFA 1000 photographs.
The information currently stored in the database shows time as Moscow time, and other parameters such as quality, cloud cover, altitude and sun elevation without any units.
