E) military specification

Question

Quizplus · Accepted Answer

The smallest feature that a GIS can detect is determined by the resolution of the scanner used for remote sensing. Remote sensing is the technique of gathering information from a distance using satellite or airborne sensors that capture images of the Earth's surface. The resolution of the scanner refers to the size of the smallest feature that can be accurately detected in the resulting image. Therefore, the smaller the resolution of the scanner, the smaller the features that the GIS can detect.
