"Suri Pluma is a satellite image processing tool and visualizer. It can open the most common image formats without importing to an internal format and minimizing the memory required for visualization. It is designed to be modular and extensible. It has a meassurement tool (distance and areas with error estimation) and geographical and map coordinate information."
Check out the screenshots and consider downloading it in case you're interested. Meanwhile, you can also go through a previous post that's again related to visualization.
