I have search up and down the site and though it must be obvious I am not seeing it. How does one go to report incorrect geolocations, incorrect spellings, missing places?
We are evaluating using your data, and running tests have found data for Benidorm in Salamanca (Spain) there is no town there. You can check up on other mapping systems to verify. So ... how does one go about this? How long does it take to be available on data download? etc.
We've looked into this and according to one of our main data sources there is indeed a Benidorm on the outskirts of Cabrerizos, Castilla y León 37219, Spain. This is on the SA 804 roughly North East of Salamanca; investigation of recent satellite imagery would suggest that this is new development which may be why you're not seeing any other corroborative sources (although we've logged a request for clarification and confirmation with the data source to be thorough).
So for now at least, it would appear that this Benidorm is less an incorrect geolocation and more an emerging place; but we'll keep an eye on this in our next update.
