Abstract

The availability of satellites with increasingly better resolution has been a trend since the 1970s. From Landsat MSS to Landsat TM, to SPOT, to IRS, there has been a 100 fold improvement in size of objects that can be seen on the ground. The next generation of satellites will have a 25 fold increase in resolution, from 5 meters to 1 meter. The OrbView 3 and OrbView 4 satellites, being built by Orbital Imaging Corporation (ORBIMAGE) will have the capability to image objects on the ground at one meter in panchromatic, and 4 meters in multispectral. These sensors will permit satellite data to be used in applications formerly available only with aerial photography. OrbView 4 will also carry the first hyperspectral sensor ever flown commercially. It will deliver over 200 bands of spectral imaging capacity. Since 1984 the best multispectral sensor, Landsat's Thematic Mapper, imaged in 7 bands. OrbView 4's 200+ spectral bands at 8 meter resolution will greatly expand the use of satellite data in mining exploration, land cover analysis, agricultural assessment, and forestry applications.
