How many channels has the multispectral sensor of WorldView-2?
8-band
WorldView-2 is the first commercial satellite to carry a very high spatial resolution 8-band multispectral sensor. Focal planes on the WV2 sensors are enhancements over those used on QuickBird (QB).
Is WorldView-2 still operating?
WorldView-2 is an imaging and environment-monitoring satellite from Maxar of the United States which launched on 8 October 2009 and remains operational. It is the follow-on spacecraft to WorldView-1.
What is the spatial resolution of WorldView?
WorldView-3 Satellite Sensor (30cm) WorldView-3 satellite provides 30cm panchromatic resolution, 1.24 m multispectral resolution, 3.7 m short wave infrared resolution (), and 30 m CAVIS resolution. The satellite has an average revisit time of <1 day and is capable of collecting up to 680,000 km2 per day.
What are the band designations for the Landsat satellites?
Landsat 8-9 Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS)
| Bands | Wavelength (micrometers) | Resolution (meters) |
|---|---|---|
| Band 5 – Near Infrared (NIR) | 0.85-0.88 | 30 |
| Band 6 – SWIR 1 | 1.57-1.65 | 30 |
| Band 7 – SWIR 2 | 2.11-2.29 | 30 |
| Band 8 – Panchromatic | 0.50-0.68 | 15 |
How many bands does WorldView 2 have?
eight spectral bands
WorldView-2 is distinctive in that it captures high resolution imagery with eight spectral bands, as compared to the usual four band satellite range.
How many bands does QuickBird have?
four multispectral
Satellite imagery (e.g., Quickbird) consisting of four multispectral bands (blue: 450–520 nm, green: 520–600 nm, red: 630–690 nm, NIR: 760–900 nm) at a 2.4-m spatial resolution and a panchromatic band at a 0.6-m spatial resolution is available from Digital Globe (Fig.
What is WorldView Legion?
WorldView Legion is a fleet of high-performance satellites that dramatically expands our ability to revisit the most rapidly changing areas on Earth to better inform critical, time-sensitive decisions.
How many bands does WorldView-2 have?
How many bands does WorldView-3 have?
8
WorldView-3 enhances our industry-leading constellation with the addition of 8 high-resolution SWIR bands as well as the 12 bands of CAVIS.
What is band 1 in Landsat?
The Operational Land Imager Band 1 (0.433-0.453 µm) on Landsat 8 and Landsat 9 is useful for imaging shallow water and tracking fine atmospheric particles like dust and smoke. Band 1 reflects blues and violets, where light is scattered by dust, smoke, and water particles in the air.
How many bands does Sentinel 2 have?
13 spectral bands
The Sentinel-2 MultiSpectral Instrument (MSI) acquires 13 spectral bands ranging from Visible and Near-Infrared (VNIR) to Shortwave Infrared (SWIR) wavelengths along a 290-km orbital swath.
What is the highest resolution satellite imagery?
The Maxar satellite constellation provides the highest-resolution (natively collected) imagery in the commercial market. We collect about 680,000 sq km of 30 cm imagery every day, providing an abundant inventory to create 15 cm HD.
