Deniska (http://deniska.dcemu.co.uk/) has updated his awesome Map This! application for the PSP with a new Beta release, heres whats new:


CHANGES
-----------

- address lookup for US addresses (via TIGER line data)
- reverse lookup (shows the closest known house numbers or intersections)
- new logo, startup screen, wallpaper (contributed by DaxDce)
- re-designed interface: new fonts, menus, some layout changes, more skinable data panels, battery & signal icons, etc..
- some bug fixes: clock desplay, POI layout problem, etc.
- bundled with small NYC map and corresponding geodata file. (~1Mb)


Creation of US geodata file:
I provided a set of scripts & programs (all with sources) to get the Tiger Line data from US Census Bureau. They have been tested under cygwin (http://www.cygwin.com)...
Perhaps someone (in7ane?) could convert that code in to some kind of GUI program.

To generate the geodata file for a state do following:
1) copy geocoder folder to your cygwin home directory
2) navigate to that folder (using cd command) under cygwin prompt.
3)run following command:
./geo-map.sh [2-letter state abbreviation in capitals]
Example: ./geo-map.sh NY
4) wait for a few hours while it creates geodata.dat file
5) copy geodata.dat file to your map's folder.

Some notes:
-Some code and ideas were borrowed from Dan Egnor's geocoder (http://ofb.net/~egnor/google.html) but the data was rearranged and compressed to allow reverse geocoding and ~3x smaller resulting file.

- Intergrity of comressed data in geodata.dat file can be cheked with decompr comand:
./decompr deodata.dat [zipcode]
This should extract all the geo entries for a given zipcode (useful for troubleshooting)
- With some minor alteratoins the script can be used to produce geodata file for any given area (from few zipcodes to few states)
I attached the county codes file for easy reference to tiger line data.
Perhaps a reference file, listing min/max GPS coordinates for each county could be created. The program then would compare the map's lon/lat span with those coordinates to extract a set of counties corresponding to that map and process only these counties.

This looks like its all coming along nicely, just wondering if there is any way that its compatible with Sony's GPS unit, and if soare there any UK maps available?

I believe it requires a hardware modification to the PSP

If you want GPS function, yes. Otherwise it is like a portable mapquest. You download your own maps and put them on the PSP and this will display them.

I can't get it to work . I am really good in does but cygwin(linux?) I am not that good in. Anyways I get a bunch of no such file or directory when I type ./geo-map.sh NY. I 'd love to try this but I am not sure what I am doing wrong or whats up with it.
