Is there a known update frequency for map vendors such as NAVTEQ? There have been major changes to SOCAL freeways in the last couple of years, but I do not see any updates by NAVTEQ on their WEB site.
Similarly, I have been watching GOOGLE earth during a three year construction project of the I-215 / CA-60 interchange which opened for traffic just last week, but GOOGLE EARTH satellite images have not changed during the three year interval.
Has anybody actually seen any changes to either NAVTEQ or GOOGLE EARTH?
I am of the opinion that Google Earth choses images based on the highest resolution, not the most up to date, images.
At least Google Maps is now encouraging user input on business locations.
I've seen changes in Google for new roads around here.
I noticed that in Albuquerque too with Google Maps. Check the satellite images from Microsoft's Live Search Maps in the Hybrid View. I see they are more current for my area so you might give that a shot.
If you click on 3D it will load Virtual Earth beta (Google Earth equivalent)
Are amazing...I was looking at my Parents farm., you can tell if they just mowed the lawn,who's car is in the driveway..wow...and Cedar Point you can see each ride..
Google Earth seems to be random. My home is still on a 5 year old image (summer 2002), but 10 miles north La Plata, MD is only a few months old (summer 2007). The pane just west of me is very low resolution without enough detail to determine an approximate age.
than Google Earth. I ckecked out your link and Virtual Earth shows the new freeway construction in the satellite images where Google Earth doesn't. Now I hope NAVTEQ will put it in their maps so it will show up in a future GARMIN map update.
Thanks for the link
my pleasure... http://maps.live.com/ works great for me too.
.... and Google Earth don't even match up. On Google maps, a major interchange in Ft. Worth TX at I-35W and the MLK freeway shows a loop ramp on the northeast corner. On Google Earth you see an identical loop ramp on the southwest corner, but it doesn't exist on Google Maps, nor is it shown on my MS Street and Trips 2006. That indicates to me that the exit was changed at least 4 years ago, but it's still showing on the satellite pic.
It's a good thing we have lots of ways to crosscheck these things. The old loop ramp is also not shown on the NT2008 map on my Nüvi 260, so I'm expecting that it will route me correctly when I go through there on Saturday.
It seems as though Google Earth does eventualy get updated but not all in one shot. It looks like satellite imagerary to map is a long process. It explains why some parts of NA are accurate and others are outdated.
Some interesting facts on Google Earth:
One of the changes to Google maps in recent months is the addition of street view in certain locations. The Dallas / Ft. Worth area has pretty good coverage. These are actual photos taken from a vehicle as it navigated all the streets. At least part of the interchange you are talking about is covered. You can actually "drive" your route seeing the roads and signs from your computer. Check it out.
I just "drove" in from the north on I-35W, took exit 51 and the flyover ramp to 287.... nice to know ahead of time what to expect.
