Jarvis Island Maps & Photos
This map of Jarvis Island is based on; the 1924 elevation contour map drawn by Chester K. Wentworth of the Whippoorwill Expedition, the 1941 map drawn by E. H. Bryan, Jr. in Captain Bryan's Pacific War Atlas (1943) and the 1958 modification of this map drawn by Harold G. Jewell, Jr. in 1958 during the IGY.
This LANDSAT 3 Image, taken on January 11, 1979, is the earliest space-based photo of Jarvis island I have found (free that is) so far. LANDSAT 3 orbited at an altitude of XXX nautical miles.
These three photos were taken from the space shuttle Discovery on October 9,1990 from an altitude of 162 nautical miles. The times of the three shots are 21:31:04, 21:31:13 and 21:31:25. The azimuth was 110 degrees meaning it was only 20 degrees off vertical, so these pictures are a good representation of Jarvis Island's true shape.
This is a higher resolution image of the third photgraph of the 1990 Discovery series of Jarvis island This photo was taken as part of the Reefbase Metadata Project. A number of Space Shuttle photographs focussing on tropical coastal areas have been scanned by ReefBase. ReefBase is a project by the International Center for Living Aquatic Resources Management (ICLARM), and aims to make reef information available to a wide audience in order to promote awareness and informed management of coral reef systems.

Compare the obvious extensive shoal to the east of Jarvis Island in the above photo with the following 1986 navigation map of Jarivis Island from Flags & Maps
The image on the left is a rather poor shot of Jarvis Island from the space shuttleColumbia on July 1, 1992. The time was 23:17:40. It was taken from an altitude of 162 nautical miles and an azimuth angle of 338 degrees. Compare it to the shot taken from the space shuttle Discovery on August 28, 1985 from an altitude of 193 nautical miles and an azimuth of 16 degrees.
This image of Jarvis Island was taken in December of 1999 by the space shuttle Discovery. It is by far the highest resolution image taken from space yet. Its altitude, unfortunately, was 317 nautical miles, or the image would have been even better. Compare this image with a recent vegetation map done by Mark Rauzon for his thesis Feral Cats on Jarvis Island: Their Effects and Their Eradication (1985)
Now compare it to this stunning stereo image of Jarvis taken from the International Space Station. The photo was taken on 16 June 2001, 23:07 GMT. The altitude was 213 Nautical Miles and the sun angle 68 degrees. This is a "cross-eyed" stereopticon so just cross your eyes until the two images merge.
