A couple of things before I post the app:

(1)
Regarding this:
NOTE:
In theory, 2 or more counties can share area with same zipcode(s), ie you may get the same zipcode filename in 2 different county zipfiles. In this case you'll have to merge the zipcode files with a same name and sort the data inside of them alphabetically by street name.

This does not seem to be the case (eg. 02068.zip 99704 and 02090.zip 99704 are the same)

Could you give me a case where this is not so. To confirm that I do have to deal with both scenarios (where zipcode files are the same and also where they are partial).

(2)
zip.txt does not have entries for every zipcode, eg:

07086,40769504,-74021890, ,,3472,69785
(7th in Manhattan one you posted)

-

Here goes nothing: http://homepage.mac.com/f.levin/psp/GeoData0.2.0a.zip

Until deniska confirm this as working, and all the pre-processed files are there, this is experimental and probably not ready for use.

I am still dumping the data for different states to http://glockdancers.com/mapthis/ - it will probably take me another week to finish it.

1) I don't have any examples to prove my theory yet - so for now you could just overwrite the file with the same zipcode name...
We'll see if someone reports a problem with that.

2) I am aware that zip.txt is incomplete...
Escentially, it not cruicial to the geodata creation...
It's just that some adresses would not have city name in them...

If could try to look up/update missing zipcodes via yahoo's geocoder:
http://developer.yahoo.com/maps/rest/V1/geocode.html
examle:
http://api.local.yahoo.com/MapsServi...Demo&zip=11230

But I would not rely on this look up during the runtime - since it is just a demo with limited access...

Some comments about the gui:
I generated a sample file and it worked for my area...
Perhaps you could display the names of the counties on that spreadsheet (using counties.txt file fo reference) - I am sure this could be usefull for some people...
Overwise - good work!

POIs - you can have up to 10 different icons displayed simultaneously... (again see the forums for details)
Sorry, but it's annoing to to keep answering same questions over and over again...

I'm really sorry for disturbing you, deniska. Probably it's time to make a FAQ on main page. Forum post's comments is to tangled data source for this kind of questions.

I nominate howl to be the official organizer.

Cool, thanks!

I gave it a quick try with a small Manhattan map and crashed on the first attempt
(sorry I did not copy the exception message)

The second and third attempts succeeded w/o a problem...

Could that be that I somehow changed the focus (I did some scrolling inside the county pane during the first try..) and that messed the program up..
Anyway, next time it crushes I'll catch the error message and send it to you...

deniska, I'm trying to get the UK postcodes (http://www.freethepostcode.org/) into a usable geodata format. A few issues though - I suspect when you parse the lat/lon you assume the longitude is negative, and the search function requires a minimum number of characters (and a street number?).

So far I got the reverse geolookup to work once - but can't replicate that

If you have time could you take a look and if you have any idea what I'm missing.

---

Regarding the crash - I suspect it may be due to the county column in the data grid having been edited, but tell me if it happens again and I'll try and replicate and fix it.

Also, files on http://glockdancers.com/mapthis/ are no longer accessible.

Could you confirm that zip.txt is not required in the _map folder on the PSP.

deniska can u help wit this new release cuz i'm way behind......i don't get the geodata thing....wat does it do??? if i search a address on my psp using this release wud it make a POI automatically??? and does the geodata dat u provided on this release w/ the NY map works on any state like CA,AZ,MD, etc...that way i don't hav to make me own cuz the create ur own geodata thing looks complicated....all the cygwin and stuff...thanks!!! also good job on this release!!!

I suppose since I'm in TX I'm S.O.L. with the geodata.
1-click crashes the app; old tiger isnt supported. Oh well I guess I can keep myself entertained with poi's for now.

We make and sell GPS-PSP cable. It supports Holux 236/238/240.

According to our test, Holux's GPS receiver is better than SONY's.

Now we have shipping agent in USA and the cable can be delivered within 2-5 days.
