I guess it depends on the quality of your local database. Here we see new streets and quarters on Google Maps that do not yet exist in reality (but have been planned and will be built). |

The local database is fine, it just takes google a long time to use the updates. > Here we see new streets and quarters on Google Maps that do > not yet exist in reality (but have been planned and will be built). That not necessarily due to the quality of the local database. We saw the google car show up again here almost 18 months ago, after it had been here previously more than 10 years previously. The second time they only zoomed thru some of the main streets in town and didn't even bother to visit the new roads and houses. |

I do a lot of work with local GIS departments and the quality is extremely variable. Some are on top of it and others are completely out of their depth. At least one uploads their edits to ESRI and not Google. Google puts their dispatch center in the wrong place so they don't exactly trust them. There are several big players like HERE (formerly NavTeq) and TeleAtlas. Licensing their data isn't cheap and depends on how frequently you want it updated. TIGER/Line is the US Census Department and the data is free but the update cycle is slow. It's interesting to take the data for the same area from several different sources, overlay it, and see where it differs. |
