WorldView-2 Instruments
| Imager type | Pushbroom imager (or a line scan imaging system) |
|---|---|
| Imaging mode | Panchromatic (Pan) |
| Spectral range | 450-800 nm |
| Spatial resolution at nadir | 0.46 m GSD (0.52 m at 20º off-nadir) |
| Swath width | 16.4 km (multiple adjoining paths can be imaged in a target area in a single orbit pass due to S/C agility) |
What are the types of spatial resolution?
In remote sensing we refer to three types of resolution: spatial, spectral and temporal. Spatial Resolution refers to the size of the smallest feature that can be detected by a satellite sensor or displayed in a satellite image. It is usually presented as a single value representing the length of one side of a square.
How many channels has the multispectral sensor of WorldView 2?
The WorldView-2 sensor provides a high-resolution panchromatic band and eight (8) multispectral bands; four (4) standard colors (red, green, blue, and near-infrared 1) and four (4) new bands (coastal, yellow, red edge, and near-infrared 2), full-color images for enhanced spectral analysis, mineral mapping, wildlife …
What is the spatial resolution of WorldView 3?
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.
How many bands does WorldView 2 have?
eight spectral bands
This satellite is capable of collecting up to 975,000 km² of imagery per day and offers unsurpassed accuracy, agility, capacity and spectral diversity. WorldView-2 is distinctive in that it captures high resolution imagery with eight spectral bands, as compared to the usual four band satellite range.
What is spatial resolution in radiography?
Spatial resolution in radiology refers to the ability of an imaging system to differentiate between two near-by objects. In digital imaging, it depends on the size of the pixel used.
What is spatial resolution in digital image processing?
Spatial resolution is a term that refers to the number of pixels utilized in construction of a digital image. Images having higher spatial resolution are composed with a greater number of pixels than those of lower spatial resolution.
Which sensor provide high resolution pan images?
The ETM+ sensor scans a spectrum of eight bands with high resolution to provide images of Earth’s surface with resolutions of 30 m for a multispectral TM image and 15 m for a panchromatic image (LPSO).
How does WorldView-3 work?
WorldView-3 builds upon WorldView-2 and WorldView-1 technology by carrying forward the satellites’ advanced CMGs (Control Moment Gyroscopes). The CMGs, developed at BATC, reorient a satellite over a desired collection area in 4-5 seconds, compared to 30-45 seconds needed for traditional reaction wheels.
