What is Quick Bird image?
QuickBird was a high-resolution commercial Earth observation satellite, owned by DigitalGlobe, launched in 2001 and reentered after orbit decay in 2015. QuickBird used Ball Aerospace’s Global Imaging System 2000 (BGIS 2000). At this resolution, detail such as buildings and other infrastructure are easily visible.

What is the best free 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.

How many megapixels is a satellite?
Unlike NASA’s pictures, this satellite produces 121-megapixel images that capture the Earth in one shot instead of a collection of pictures from multiple flybys stitched together.
What happened to the Ikonos satellite?
While capturing at a slightly lower resolution than its successors, IKONOS imagery was the first of its kind, and offers the best archive of high resolution historical satellite data available. However, like QuickBird, the IKONOS satellite stopped collecting imagery as of December, 2014.
What is the IKONOS sensor?
The IKONOS sensor was the first commercially available submeter resolution sensor, having been launched in September, 1999. While capturing at a slightly lower resolution than its successors, IKONOS imagery was the first of its kind, and offers the best archive of high resolution historical satellite data available.
What is the resolution of IKONOS imagery?
With an altitude of 681 kilometers and a revisit time of approximately 3 days, IKONOS produces 1-meter resolution panchromatic and 4-meter resolution multispectral imagery that can be combined to accommodate a wide range of high-resolution imagery applications. See IKONOS for more details.
What is the IKONOS-2 programme?
It is part of ESA’s Third Party Missions Programme, in which ESA has an agreement with DigitalGlobe to distribute data products from the mission. At the time of its launch, IKONOS-2 brought imagery rivalling that of military spy satellites to the commercial market.
