| Description | |
| Abstract | A multi spectral spot image
was used in a poster that was published by AUSLIG in 1992. This image
(not the poster) was then scanned by AGSO on September 4th, 2000. Both
TIFF and JPG files exist. This image was created to be used in areas (eg.
center of southern atoll) where there was no orthophotography coverage. This TIFF image is best used at a scale no less than 1:50000, zooming in past this results in a pixelated image and a loss of definition. |

| Lineage | Spot satellite imagery was originally aquired in April 1987. This was then made into a poster and publised by ANZLIC in 1992. Since then the image has been scanned by AGSO (September 2000) using a high resolution drum scanner. The image is in TIFF format and has been geolocated and a TWF file created. |
| Positional Accuracy | The TFW file was created by matching the TIFF image against the vector line work of the southern atoll. Because of the loss of definition as you zoom in on the image, the lines cannot be matched very precisely. This results in positional accuracy around 40m of reference lines. |
| Attribute Accuracy | not applicable |
| Logical Consistency | not applicable |
| Completeness | Both the scan of the Spot image and the geolocation is complete and no changes or amendments are planned. |
