WorldView-2 Satellite Sensor
WorldView-2 is a commercial Earth observation satellite equipped with a high-resolution optical sensor. It is part of the WorldView series operated by Maxar Technologies formerly known as DigitalGlobe, a company that provides geospatial information and satellite imagery. Here are some key features and specifications of the WorldView-2 satellite sensor:
Launch Date: WorldView-2 was launched on October 8, 2009.
Spatial Resolution: One of the notable features of WorldView-2 is its high spatial resolution. It is capable of capturing imagery with a spatial resolution of 46 centimeters (18 inches) in the panchromatic (black and white) mode and 1.84 meters (6 feet) in the multispectral mode.
Multispectral Bands: The satellite sensor has eight multispectral bands, covering a range of wavelengths from visible to near-infrared. These bands are useful for various applications, including agriculture, environmental monitoring, and land cover classification.
Panchromatic Band: In addition to the multispectral bands, WorldView-2 has a panchromatic band that provides high-resolution black-and-white imagery. This band is particularly useful for detailed visual interpretation and mapping.
Spectral Capabilities: The multispectral bands of WorldView-2 cover the following spectral ranges:
Coastal: 400 - 450 nm
Blue: 450 - 510 nm
- Green: 510 - 580 nm
Yellow: 585 - 625 nm
Red: 630 - 69 nm
Red Edge: 705 - 745 nm
NIR1: 770 - 895 nm
NIR2: 860 - 1040 nm
Revisit Time: The revisit time of the WorldView-2 satellite is dependent on various factors such as its orbit and the imaging task. However, it generally can revisit specific locations on Earth frequently.
Applications: WorldView-2's high-resolution imagery has diverse applications, including urban planning, agriculture monitoring, environmental assessment, disaster response, and defense intelligence.
Orbit: The satellite operates in a sun-synchronous orbit, which means it passes over specific areas of the Earth at the same local solar time on each orbit.
