Hurray, US and more geodata now available in OSM format, ready 2 convert to Mapthis

Don't know about you, but I don't have internet access in the car .

The idea is that Map This!'ll show you where you are on the map, when on the go.

i know i dont have internet access in the car. when i said google maps i thought it was assumed that everyone realized they were downloaded and not accessed on the fly in the car

OK, I don't understand you. Basically, you can download graphical maps from Google Maps, and geodata from www.openstreetmap.org, both for use in Map This!. Or do you mean something else?

[M1ke]

nope you got it

[M1ke]

so how do I get the us geodata. Nieko, your readme.txt in process.zip was dutch specific so what would be different for the us.

can I use any of these files for the us? I found them on that same site you used to get europe data
http://edc2.usgs.gov/geodata/index.php

thanks

I think GMDL has rather good support for US geodata, but haven't tried it out myself.

My scripts are Dutch specific in that I had a list of all zip codes+cities and their coordinates. That's the main thing you'll need, except OSM data. Perhaps such a list can be extracted from OSM data as well.

Geodata lookup in Map This! is done using zip code first, then for streets within that zip code block (ideally). This means you'll have to search in O(m+n) instead of O(m*n) (sort of). Having m ~= n is a good idea of course, but may not always be possible.
