What is geometric error? Describe various techniques used for geometric correction of a remote sensing image.

Geometric error in remote sensing refers to the distortions in the spatial representation of an image due to various factors, such as sensor movement, Earth's rotation, terrain variations, and inaccuracies in data acquisition. These errors cause misalignment between image pixels and their actual ground positions, affecting the accuracy of spatial analysis. Geometric correction is essential to rectify these distortions and ensure that the remote sensing image accurately corresponds to real-world coordinates.

Types of Geometric Errors

1. Systematic Errors: These errors arise from predictable and consistent distortions related to sensor geometry and platform motion. Examples include scan skew, _______ ___ ___ _____ ____ _________.
