Che io sappia non ci sono "indicatori di qualità". Comunque, proprio poco fa è apparso questo post nella dev list, che propone di aggiungere una possibilità di marcare delle tiles come "complete", in modo da concentrare, ovviamente, gli sforzi in quelle "non complete". Di seguito incollo il post (in inglese). Vi faccio sapere eventualmente gli sviluppi, e, se lo reputate opportuno, posso intervenire proponendo una sorta di "indicatore" come proposto da Andrea. Magari servirebbero più indicatori (tipo qualità delle strade, delle strade ciclabili, delle amenity, ecc ecc). Fatemi sapere! Mario === Posted to talk and dev This post really follows on from my consideration of Completeness metrics. A number of experienced OSMers who have mapped out there areas have either contacted me directly or posted through the lists about areas of OSM that are essentially complete, at least as complete as you would expect from a conventional on-line map or better. For those of us who are having to move to new areas to map and to help others who need to know if an area is "complete" there is a need for a method of communicating completeness. This will be especially important across Europe and the USA over the next year or two as the majority of the mapping is completed. As mappers we rely upon the coding developers to provide the tools to allow us to do our work. This email is a plea to any developers who are interested in working on completeness tool(s), one possible method for which is described below. We need a logical method of recoding completeness and a method for annotation about the completeness so that it can be conveyed to others. There is one method that I think might work very well and that is the method that was employed by the http://www.useyourpaths.info/interactive.php project in the UK where you could click on OSGB grid squares and flag that all the public footpaths on the OS mapping in that area had been walked and verified. Once a person had verified a square it was marked by giving it a green semi transparent overlay. Zoom in on the map linked above to see what I mean. It would seem relatively straightforward to me to apply a similar approach to OSM using the Mapnik Zoom 18 tiles as a background and applying a semi transparent coloured overlay for each tile that is complete and a link to the username of the person that last verified the time so that others can get in touch with them. I would envisage that each tile would toggle on or off (visible or false) and that the change history would be recorded and available through the API. I would see the display end of things working similarly to the manner that the namefinder/export or Chris Schmidt's recent API viewer would work. The later activates from the layers control on the map view which is the logical place to provide any completeness facility in my view. Discussion open.....
