# Feature quality map
The map matcher relies on distinct terrain features to localize in-flight. To help users optimize their mission plans for Cyclops performance and accuracy, we built a "quality map" tool. This creates a visual representation of the feature diversity within your map boundary, highlighting where the system may perform best.
### Generate a quality map
On the Maps page, you will see an option to **generate a quality** map. Click the button to begin the generation process. This is much faster than map generation, but processing times still scale with map size. A large map (>5,000 km2) will still take a considerable amount to time to generate.
