Automatically generated mosaic lines may have suboptimal local paths (such as crossing obvious feature characteristics, following shadow or cloud boundaries, passing through areas with significant color differences, etc.), requiring fine-tuning through manual interactive edit.

Manual interactive edit can optimize the geometric shape of mosaic lines, effectively solve the problem of suboptimal local paths, eliminate image seams and feature misalignment, and thus improve the quality of output result..

The Image mosaic tab's Map Editing group, Objects group, and Feature Editing group provide tools for editing mosaic lines, including the following:

Basic Editing Operations: Introduces several common operations in the map, including the use of undo and redo functions.

Snapping Settings: Introduces how to set and use snapping rules.

Objects: Introduces how to draw objects; in mosaicking, only focus on drawing related to polygon objects.

Feature Editing: Introduces how to optimize the geometric shape of mosaic lines by editing nodes, drawing lines to modify borders.
