Age 15Explain it to a 15-year-oldConnect it to the formula
A rectangular raster pixel's nominal ground footprint is the product of its two orthogonal ground sample distances. This page isolates cross-track ground sample distance and verifies it in the original relationship. The rule is b=c/a. Its input values are pixel ground-footprint area, along-track ground sample distance, and the main result is cross-track ground sample distance. For example: along-track ground sample distance=0.4 and cross-track ground sample distance=0.5 produce pixel ground-footprint area=0.2.
CollegeExplain it at college levelState the model precisely
This calculator evaluates the stated raster pixel ground-footprint area: solve cross-track ground sample distance relation over the valid real-number domain stated below. The implemented relation is b=c/a, evaluated from pixel ground-footprint area, along-track ground sample distance to produce cross-track ground sample distance. A rectangular raster pixel's nominal ground footprint is the product of its two orthogonal ground sample distances. This page isolates cross-track ground sample distance and verifies it in the original relationship. Oblique viewing and terrain can make actual footprints nonrectangular and spatially variable.
Inputs and valid domain
- pixel ground-footprint area must be a finite real number.
- along-track ground sample distance must be a finite real number.
Important boundary: Oblique viewing and terrain can make actual footprints nonrectangular and spatially variable.
The formula
b=c/a
How the calculator works through it
It substitutes pixel ground-footprint area, along-track ground sample distance into the formula and exposes every numerical step above. The main output is cross-track ground sample distance, accompanied by Reconstructed pixel ground-footprint area.
Read the result correctly
The cross-track ground sample distance is the direct answer to “rearrange the raster pixel ground-footprint area relationship and solve for cross-track ground sample distance.” Read it with the units shown beside the inputs; a sign, angle, percentage or rate changes what the number means.
