What is the resolution of satellite imagery?
Resolution refers to the smallest size an object or detail can be represented in an image. Higher resolution means that pixel sizes are smaller, providing more detail. For example, 30cm resolution satellite imagery can capture details on the ground that are greater than or equal to 30cm by 30cm.
What is the range of satellite camera?
GeoEye-1 Satellite Sensor Specifications

What cameras do satellites use?
resolutions. IRS-1C spacecraft carries three cameras: Panchromatic camera (PAN), Linear Imaging Self-Scanning sensor (LISS-3) and Wide Field Sensor (WiFS).
What is the size of a satellite image?
For example, the GSD of Landsat is ≈30m, which means the smallest unit that maps to a single pixel within an image is ≈30m x 30m. The latest commercial satellite (GeoEye 1) has a GSD of 0.41 m.
What does 50cm resolution mean?
In remote sensing, spatial resolution refers to the size of the smallest possible feature that can be displayed in a satellite image. A satellite with a resolution of 50cm per pixel takes clearer images showing finer details than a 10m per pixel resolution satellite.
What is the maximum pixels on a camera?
50.6 Megapixels, The EOS 5DS and EOS 5DS R cameras offer the highest resolution capture in the history of EOS: a Canon designed and manufactured, full-frame 50.6 Megapixel CMOS sensor.
How much can a satellite zoom?
With how much precision can a satellite zoom onto Earth? Commercially available satellite images used to be restricted to resolutions of 50 cm per pixel until 2014, and are currently restricted to 25 cm per pixel.
How clear is a satellite image?
DigitalGlobe, the leader in satellite imagery, offers public images that display detail at 30 centimeters-per-pixel. The Vexcel images are clearer than that. Thirty centimeters per pixel, incidentally, is 90 centimeters for three pixels — or about three feet.
How many centimeters per pixel is a satellite image?
DigitalGlobe, the leader in satellite imagery, offers public images that display detail at 30 centimeters-per-pixel. The Vexcel images are clearer than that. Thirty centimeters per pixel, incidentally, is 90 centimeters for three pixels — or about three feet.
What does spatial resolution mean in satellite images?
Spatial resolution refers to the size of one pixel on the ground. A pixel is that smallest ‘dot’ that makes up an optical satellite image and basically determines how detailed a picture is. Landsat data, for example, has a 30m resolution, meaning each pixel stands for a 30m x 30m area on the ground.
What is the best resolution for satellite images of a house?
The best resolution comes from Sentinel satellite data : 10 to 20m per pixel, which is quite enough for monitoring crop growth or forest clearing. But you won’t be able to distinguish your own house; even a construction as large as Colosseum will appear as a small dot. Using satellite monitoring for remote fields management in one platform!
What is the resolution of a camera image?
Camera image resolution is defined by the number of pixels in a given CCD or CMOS sensor array. This will be identified in a camera data sheet and shown as the number of pixels in the X and Y axis (i.e 1600 x 1200 pixels). The application will determine how many pixels are required in order to identify a desired feature accurately.
