This website is for OpenStreetMap users to rank the quality, and to improve the quality, of various places.
</p>

<p>
Each aspect has its own icon, and each icon has a (color-blind friendly) color scheme to show its quality. <br />
By default everything is ranked as unknown (grey color). <br />
After logging in users can assign the appropriate color.
