Observations of mapping behaviour on OSM can give an insight into recognizing recurrent mapping problems our mappers are facing. Here are few of the issues observed between 18th July - 28 nd July on OSM:

• House numbers were given in name=* tag: 1. Community responded with a comment and provided building wiki resource to the user.

• ‘casa’ spanish for ‘Home’ were given to residential buildings:1. Community responded with a comment.

• Buildings were given name=* tag with key values such as ‘Cra’, ‘Calle’, ‘Betos’, and house numbers: [1] (http://www.openstreetmap.org/changeset/38657218#map=17/11.00815/-74.79661). Community responded with a comment.

• Classification of highways were changed in Moscow: 1. The Russian community responded with a comment.

• Lots of untagged nodes, market place was deleted: 1, 2. Community member reverted 1st changeset and commented on the 2nd one.

• Retraced highway over previously existing one creating crossings: 1. Community responded with a comment.

• Deleted highway: 1. Community responded with a comment.

• Castles added: 1. Community member responded with a comment.

• Lot of highway=road tags: 1, 2.

• Failed import: 1

• A ton of tourism = attraction, tourism = camp_site tags added:

If you come across any unexplained mapping from an OSM user, let them know through changeset comments. It starts a constructive discussion we can learn from and creates a positive environment for the OSM community to work together.

Look forward to seeing more of this next week.
