What is the special resolution of IKONOS image?
Launched on September 24, 1999, IKONOS is the world’s first commercial satellite providing very high resolution (up to 1 m) imagery of the earth. The IKONOS satellite is operated by Space Imaging Inc….IKONOS Orbit.

What was the main contribution of IKONOS satellite to the Earth remote sensing?
IKONOS was a commercial Earth observation satellite, and was the first to collect publicly available high-resolution imagery at 1- and 4-meter resolution. It collected multispectral (MS) and panchromatic (PAN) imagery.
Is IKONOS data free?
The Commercial Data Purchases (CDP) Imagery Collection contains IKONOS imagery and is archived at the USGS Earth Resources Observation & Science Center (EROS). The CDP supports the Commercial Remote Sensing Space Policy (CRSSP) by providing data to qualified Federal users at no cost.
What does IKONOS stand for?
image
IKONOS (Greek for image) was one of the first commercial satellites to serve imagery to the public. In 2000, it was a big upgrade with blue, green, red, and near-infrared (NIR) at 4-meter resolution. In addition, it collected 1-meter panchromatic images and stereo imagery.
When did IKONOS launch?
September 24, 1999
Ikonos/Launch date
IKONOS launched from Vandenberg Air Force Base Launch Complex 6 on September 24, 1999. A Lockheed Martin Athena II rocket placed IKONOS on orbit 423 miles above Earth.
What is high spatial resolution?
In terms of digital images, spatial resolution refers to the number of pixels utilized in construction of the image. Images having higher spatial resolution are composed with a greater number of pixels than those of lower spatial resolution.
Is the number one in remote sensing satellites?
The IRS system is the largest constellation of remote sensing satellites for civilian use in operation today in the world, with 11 operational satellites. All these are placed in polar Sun-synchronous orbit and provide data in a variety of spatial, spectral and temporal resolutions.

How much does a satellite image cost?
Satellite image is the easies way to obtain geographic information. Generally, average cost of a raw satellite image is approximately one dollar for each sq km. The important point here is whether the data which are obtained from satellite image will give required accuracy in GIS or not.
What is the resolution of the Ikonos satellite?
Satellite imagery with a very high panchromatic resolution of <1 m has been available since 1999 with the IKONOS satellite, and nowadays panchromatic satellite imagery with a resolution of up to 30 cm (e.g., Digital Globe, WorldView 3 and 4) is captured.
How big are the 5 bands of IKONOS?
Major advantage for rapid repeat coverage; 5 bands—R, G, B, Red-Edge, NIR Constellation of 5 satellites, 5 m pixel size, 48×48 km scene size.
What are the different types of IKONOS sensors?
ASTER (Advanced Space borne Thermal Emission and Reflectance Radiometer); ATLAS (Airborne Terrestrial Applications Sensor) JV US & Japanese Govts, launched in 1999 VNR: 3 bands, 15 m resolution; SWIR: 6 bands, 30 m resolution; TIR: 5 bands, 90 m resolution.
How did IKONOS contribute to the space age?
It collected multispectral (MS) and panchromatic (PAN) imagery. The capability to observe Earth via space-based telescope has been called “one of the most significant developments in the history of the space age”, and IKONOS brought imagery rivaling that of military spy satellites to the commercial market.
