Feature request: reportimg mapping errors in BaseCamp?

I know, it's a long shot, but I often notice mapping errors in City Navigator maps (routing the wrong way through a one-way street, a road being unpaved instead of paved, wrong speed limit, you name it). The process of reporting an error like that is a) not known to many of the users and b) not very intuitive.

What if you could click on a road in Basecamp and select Advanced -> Report error? Basecamp would highlight the clicked map segment/vector and display it's attributes and make it possible to propose new values for the attributes and/or add/delete attributes. The proposed change would then be mailed/uploaded to the Garmin carthography deparment for revision.

The advantages for this are:
- more map errors are reported, in the end giving better mapping data
- the map segment/vector can be clearly identified, instead of users using arbitrary coordinates in an e-mail, which saves a lot of guessing and searching by the Cartography department
- the proposed change only has valid attributes, not an arbitrary text, saving time once again
- the proposed changes can be filtered, so map segments with multiple reports can be processed first and if many people report the same change makes it more probable it is a correct change
- the feature can also be used to check why a route is doing weird stuff ;)

There also are disadvantages (as always):
- this will create more work for the Cartography department, since it will get more proposed changes
- users can spam use this feature to report false changes
- this can leak mapping attributes (but it will take a lot of work to get users to "copy" a map), so maybe not all attibutes shold be shown (only user recognizable ones)

This is a bit like the TomTom system of user changes to maps, but I propose it to be incorporated into the normal mapping error reporting workflow and only making it easier to report bugs.

    Reporting errors directly from within BC is a wonderful suggestion, I hope Garmin takes this seriously. You mention that the current method is not well known, so I think it is worth mentioning that Garmin has no cartography department, they don't do maps, they buy them from NAVTEQ. (Though map error reports from BC could certainly be passed on to NAVTEQ.)

    Anyone can log onto the NAVTEQ.com web site and register to become a "map reporter". They have an application that allows you to do exactly as you suggest, select a road segment on a map and report errors or changes. You can check your list of reports to see the status occasionally. I will say that the reporting application is quite cumbersome, and it takes eons for them to respond and make changes. But anyway, it's the best way to contribute our knowledge at the moment.

    I think you can also submit changes through the Garmin site, but then you get no way to get feedback from NAVTEQ as to their status, or at least you didn't a couple of years ago when I became a map reporter, I haven't checked it out since then.

    I think this is an excellent idea, and we are definitely taking it seriously.

    I would also like to point out that Garmin certainly has a cartography department (more than one, in fact). It is also true than the City Navigator maps are based on Navteq data.

    But, Garmin provides a wide range of maps (topo maps, marine maps, avionic maps, etc.) combining data from all sorts of sources.

    Point well taken, Falagar, I always learn from your posts, thanks much. I guess my experience is only with Zumo and road mapping. So if Garmin does have a cartography group, is it the case for road mapping that reporting directly to NAVTEQ is the best way currently, or is there some advantage to reporting road map errors through the Garmin website, assuming then Garmin cartographers get involved somehow? All advice appreciated in the interest of mapping accuracy!

    I have used both procedures in the past, but the Navteq website was quite horrible back then and I never had feedback from the Garmin cartograpy guys. And, more importantly, I had no way of checking if the data was wrong in the first place and might have sent in a change that didn't need changing.

    That's why I'd like a) a way to see (some of) the data of a map vector and b) have a possibillity to sugest a change to something the map attributes can handle. ;)

    And: thanks Falagar for providing direct feedback on this forum! I am a moderator at the dutch forum.gps.nl forum and we (the company who uses www.gps.nl) also are a mapping company (we create the onRoute routable motorcycle/bicycle/topo maps) and our forum is very active. We (like to) think our active participation helps. Your participation here certainly does! ;)

    I apologize if that is not a very helpful response, but this is a bit outside my area of expertise. To be safe, I'd report it to both Garmin and Navteq.

    Thank you for your kind words. At the very least, participating on the forums makes you develop a thick skin. :)

    Thanks - I keep finding map errors that I want to report - so I will report them to NAVTEQ.

    I also find Direction Errors that are Basecamp or Zumo 350 errors - not Map Errors. For example, the Map is correct but the Directions fail to list a necessary turn.

    ?? how do I report these errors to Garmin ??
