Instrument profile: IKONOS--the name is derived from the Greek word for image

Previously owned by SpaceImaging, a privately owned company that provides panchromatic and multispectral imagery for a variety of industry applications. The revisiting time for a typical site is 3 days. SpaceImaging classifies its data products by the degree of positional accuracy. The least accurate products have a 50 meter registration uncertainty; the most accurate have a 2 meter uncertainty. Stereo pairs and other options are available for many of their products. Because of the nature of IKONOS's orbit, all images are taken at approximately 10:30 a.m. local sun time.

Usefulness to land managers
Inexpensive, high quality data. Likely to be useful to those who are satisfied with panchromatic or multispectral imagery. This is a similar product to QuickBird or SPOT data.

Costs and Contacts
IKONOS images are sold on a square kilometer basis. The image costs range according to the accuracy with which they are georeferenced. Prices for two sample packages are given below (as of 23 September 2004 for USA images). Archival images cost less than new images that are obtained at the client's request. Images will have no more than 20% cloud cover, and a single point can be specified as having to be cloud-free.
