Differences between Pixel-is-Area and Pixel-is-Point Designations
Detailed Description
This graphic displays the differences between Pixel-is-Area and Pixel-is-Point designations. Some image processing software packages use the Pixel Is Area designation, whereas Landsat Ground Control Points (GCP) use the Pixel is Point, so users will need to make adjustments to use the data in the selected software.
GCPs are defined as points on the surface of the earth of known location used to geo-reference Landsat Level-1 data.
