How many bands does QuickBird have?
four
Riparian Processes and Interactions 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. 28.5).
Who has the highest resolution satellite imagery?
1. Google Earth – Free access to high resolution imagery (satellite and aerial) Google Earth offers free access to some of the highest resolution satellite imagery, although the highest resolution images are actually taken from airplanes. Most of the data on Google Earth was taken in the last 3-4 years.
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.
What is the resolution of picture?
Image resolution can be defined as the level of detail in an image. Raster images are comprised of a series of pixels, where resolution is the total number of pixels along an image’s width and height, expressed as pixels per inch (PPI).
How many multispectral bands are collected by the QuickBird sensor?
four multispectral bands
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 was the resolution of the QuickBird satellite?
QuickBird used Ball Aerospace’s Global Imaging System 2000 (BGIS 2000). The satellite collected panchromatic (black and white) imagery at 61 centimetre resolution and multispectral imagery at 2.44- (at 450 km) to 1.63-metre (at 300 km) resolution, as orbit altitude was lowered during the end of its mission life.
What can the QuickBird imagery be used for?
The sensor also has 4 multispectral bands with resolutions of 2.44 m at nadir. The imagery can sufficiently distinguish man-made features on the landscape and serve as an excellent base map for GIS applications. Regarding rangeland management, Quickbird imagery has primarily been used to classify vegetation types on a fine scale.
How big is the field of view on QuickBird 2?
The satellite collected panchromatic (black and white) imagery at 61 centimetre resolution and multispectral imagery at 2.44- (at 450 km) to 1.63-metre (at 300 km) resolution, as orbit altitude was lowered during the end of its mission life. ±30o (along-track/cross-track) providing a ±544 km wide field of regard (FOV) in the cross-track direction
How big is the file size in QuickBird?
All details about the data provision, data access conditions and quota assignment procedure are described into the Terms of Applicability available in Resources section. In particular, QuickBird offers archive panchromatic products up to 0.60 m GSD resolution and 4-Bands Multispectral products up to 2.4 m GSD resolution.
