Greetings!!!

Today I would like to share some words about the latest challenge to hit MapRoulette—the 10th Anniversary Name Fix Challenge (http://maproulette.org/#t=spellingerrors/ ; active on 8/9/2014).

OSM data is not only used for cartographic purposes, but also for route navigation and guidance (audio/text). Spelling and punctuation errors in the raw OSM data affect navigation end-user experience. At Telenav, we’ve queried the raw data and identified various types of name spelling/punctuation errors that results in less-than-ideal text-to-speech pronunciation and display. Here’s a sampling of the errors we’ve identified and pushed to MapRoulette–and suggestions on how to fix them. I’ve also included in a link below, sound bytes of the OSM names pronounced by our text-to-speech service.

If you’ve got any questions or can think of other types of spelling errors in the data, give me a shout via OSM.org or at kristenk@telenav.com
