I know they've done accuracy comparisons between themselves and other street providers, but not sure if they had an automated tool for it. best, sean Hi Alejandro -

If someone know any way or method to analyze maps and have more visual facilities to recognize mistakes, I´ll be apreciatte it.

We have data team here that goes through and does a check on data and could serve as a kernel for an editor system like Wikipedia. Although in success I think they would just be assessing the comments of the community to provide a stamp to the data set. An editor function could be anyone in the community, but will be nice to have a full time staff to get it going. There is also the question of what should be QA'd. The most obvious errors are usually geocoding and that would probably be the bulk of the work. There is also issues of copyrighted work being posted or someone maliciously posting bad data, but neither of those have been issues to date. We are not really in a position to check to veracity of data numbers (i.e. is that the correct population for Malawi), but we can check georeferencing, use of the correct borders, typos, etc. Are there other issues that people see often in geospatial data that could be QA'd?

But what exactly is the Q&A process and how does that affect data credibility? I think this is a really great idea and that the icons work fine.
