I could have picked a better adjective but wanted to emphasize that OSM should be reviewed by all utilities as a away of reducing their cost of landbase maintenance.Alfred Sawatzkyhttps://www.blogger.com/profile/15845723068853240174noreply@blogger.comtag:blogger.com,1999:blog-4451657389087868432.post-7249291260108504092010-08-01T17:22:27.160-06:002010-08-01T17:22:27.160-06:00Hi Bala,

You can find presentations <a href="http://www.slideshare.net/mukih/beyond-good-enough-spatial-data-quality-and-openstreetmap-data" rel="nofollow">here</a> and <a href="http://bit.ly/dfq23y" rel="nofollow">here</a>. Do a web search on "OSM accuracy" and you get hits on links like <a href="http://opengeodata.org/osm-wins-the-accuracy-test-yet-again" rel="nofollow">this</a>.<br /><br />I think the accuracy/currency of data varies by location, but I think any utility owes it to themselves to at least explore the possibilities of a fit with OSM in their service area.<br /><br />While OSM may not have all the data in your service area, it provides the framework for a utility to submit the new/modified landbase information and see the results in your maps within hours/days. I don't think you can get that quick turnaround with Navteq or Teleatlas or Google (see Peter Batty's <a href="http://geothought.blogspot.com/2010/05/googles-approach-to-user-generated-map.html" rel="nofollow">blog post</a>).<br /><br />So there are likely tradeoffs, but I think OSM is worth further investigation for any serious utility.<br /><br />AlfredAlfred Sawatzkyhttps://www.blogger.com/profile/15845723068853240174noreply@blogger.comtag:blogger.com,1999:blog-4451657389087868432.post-10683340626969147672010-08-01T09:50:25.917-06:002010-08-01T09:50:25.917-06:00Hi Alfred, This is a great idea!!!

Can utilities use this as their land base right away? Is there any bench mark to know if the data for an area is 99% accurate? (I am sure 100% not possible)Balanoreply@blogger.com
