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.
How can I download Ikonos imagery for free?
You can try ESA third party portal where you can find detailed information and related redirecting for accessing data. In order to download IKONOS (https://earth.esa.int/web/guest/missions/3rd-party-missions/current-missions/ikonos-2) imagery you need fast registration (approx.
Is IKONOS passive or active?
| Sensor | Wavelength | Satellite(s) |
|---|---|---|
| High Resolution Radiometer AVHRR (Passive) | IR .7-1000 µm | POES IKONOS Landsat |
| Radiometer (Passive) (examples: AMSR & SSM/I) | Microwave .1-100 cm | TRMM EOS |
| Scatterometer (Active) (example: SAR) | Microwave .1-100 cm | Radarsat QuikSCAT |
| Altimeter (Active) | Microwave .1-100 cm | TOPEX / POSEIDON |
What is an IKONOS image?
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.
Are Ikonos images free?
There are no way to freely access to HQ satellite images. They are all commercial product and sold at a high price.
What do you mean by radiometric resolution?
Radiometric resolution refers to how much information is in a pixel and is expressed in units of bits. A radiometric resolution of 11 means the pixel has 2048 possible intensities of blue, 12 bit resolution represents 4,096 shades of blue, and 14 bits represents 16,384 shades of blue.
How many bands does IKONOS have?
four bands
Landsat-TM has seven bands; IKONOS has four bands; hyperspectral sensors typically may have more than 200 very narrow bands (cf. Landsat’s seven bands). Radiometric resolution refers to the number of potential brightness values that can be stored for a pixel.
WHO launched IKONOS?
Lockheed Martin
Launch Day 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.
How do I get free IKONOS data?
Free data is not possible get access. you need to contact the concern team to purchase. Available at https://earthexplorer.usgs.gov for some areas of IKONOS Image or OrbView Image that has a resolution of 1 meters.
