HI,
I've read recently pda's are already yesterdays technology. I always thought it would be nice to know what chow-friendly places were at or along my destination in Chicago, which your proposed map or grid-system may allow. (Downloadable to a portable device would be a bonus)
Presently, I use my mental rolodex, then hunt down the information to support my memory. Or I am already on the road, then do an On-Star consultation with someone from the board. I know I miss opportunities simply because they didn't come to my mind. The information is at LTHforum, though it is not presented intuitively relative to geography.
What you propose, if I understood it correctly, will go toward where to eat when I reach destination X. Not knowing what is involved software-wise, just thinking out loud, you could potentially have a mosaic map of Chicago with major streets outlined. If your destination is in the Albany Park neighborhood, then by selecting that piece of the mosaic links you to a blow up map of the immediate area with restaurants, specialty food shops, ect. noted by number/label/hyperlink to the location details and description as proposed. Or maybe there could be a mapquest tie-in, which I have seen on other sites, to get a street map and road instructions.
Sounds interesting ... just find the time will be the challenge from your side. Installing the information will be a challenge all around.
Thanks for thinking of LTHforum.
Regards,
