    this looks INTERESTING. I'm gonna temporarily use this data over the next 24 hours or so and see if its better than the zips.dat we currently have. Will post results.

    Been running with this new data source for a while. I went back and made some updates -- dropped out churches, cemeteries and hotels, added back in the whole zip code file. I'll see what the revisions do... as it was most of the time all I got was local churches and hotels, sorta interesting but I would rather see other information. Seems pretty accurate so far though... What it isn't is complete.... which goes back to your original idea sonic -- of creating a method to add in data. The grouping that comes with this data gave me an idea --- could include a pick list/ text file? Some kind of configurable input that would allow you to filter the data groupings you want to include (or exclude). I'd write the code, but don't want to lose all the changes that Mitch made to XM/HD... Maybe we can work something out. Hopefully RR will get re-integrated soon.

    the data mentioned above is roughly 70 megs. Thats quite a drag on the system if you have it set to fire the locate command every 60 seconds.

    So on a typical 2 hour drive, you are reading 8.4 Gigs from the hard drive.... This should chew up the hard drive pretty fast, as well as probably really slowing the system down a bit.

    The compilation of new sources to make the zips.dat more accurate, was not done by enforcer. Wiredwrx put it together, and posted it in the DigitalFX 2.0 thread. You can find it here in post #1945

    In post #1960 BlueZX3 creates separate files for each state. This way you can just copy and paste whatever ones you want into the zips.dat file. This can really speed it up when it accesses as it only reads a couple states you put together that you drive frequently, and not all 8 megs with 50 states plus Puerto Rico.

    Then in post 1972 meisner wrote a script to take the individual state.dat files and create a zips.dat file of the states that you want.

    The in post 1976 meisner created a GUI for the zips.dat builder. Check the states you want, click go, and it creates a zips.dat with the info from the selected states.


    In post 1963 Sonic makes mention of movie times (Done since that posting) and local news headlines.... I would like to the see the news one

    The raw data may well be 70Mb... but it's easy to filter it down considerably. I've found the detailed points it provides pretty interesting--it's pretty rare that I don't already know what town and/or county I am in. Also, the same data source has worldwide entries which may be interesting to those outside the US.

    Your reference points for the zips.dat file is probably pretty helpful.. took me a couple hours of searching the first time to find the right post.

    Dave,

    Where did you get the ZIP_CODE from the 2 files i downloaded (split 1 and split 2) did not seem to contain ZIP CODE information.. or am I just missing it.

    Thanks

    I took the 8Mb zips.dat that mentioned in an earlier post --and wrote a little query to combine the two == that is I assigned the zip and city to each "point of interest" based on the shortest distance between the zip lat/lon and the "point of interest" "lat/lon". It works ok. Driving around my town I get correct information about schools, brooks, ponds, etc, but sometimes get next town over for zip & city.. since it isn't using boundary info, just center points for the zip area you get what you get....

    btw I'm using data from the second link, not the usgs data. Some concept would work though

    Dave, Thanks..

    Does anyone know where the zips.dat information was compiled from? My local area labels are quite a ways off...
