GEO DATA GEODTA Question, HELP, WTF

[zerodays]

Oh, thanks, I will try that asap. I've been away for a few days

Hi in7ane, the geodata.dat is still not loaded.

Could you please check what went wrong? I've posted my 15_9 folder zipped... It would be good if you can assist me on this.

Cheers

In7ane, I also realized that GDML will *not* download anything closer than 100m Scale..

According to google map I'm viewing (through GDML), I can zoom up to 20M (i.e., I can zoom 2 more from 100m scale) so that I can actually see and read out the 'numbers' attached around the blocks.

I've tried various ways to tell GDML '03b' to download those 2 close zooms, but it doesnt seem to work out...!

Some assitance would be great.

***************************************
EDIT: it seems that, in Advance setup, there 4 choices

zoom = null
x = null
y = null
min zoom = 0

as soon as GDML starts, all null and min-zoom is set to 0.
I've tried to change this value to -2 (so that I can further zoom-in)
Also, I am also setting zoom to 8...

Does this make sense???
It seems to me that (after reading lots of forum threds),
you've decided to 'disable' these 2 closest zoom, because people considered that they are a waste of spaces??

I am not sure if I'm doing it right or wrong, because im now downloading one tile zooming all the way to 8.
(As far as I can see from 'preview' I can now see even more closer zoom (than before)
***************************************
Thanks.

zerodays: did you check the Advanced options? If you fill in 0 or 1 for min zoom, things work fine for me, with 0.5.03b also.

I did also notice that in some places min zoom can be negative in Google Maps. Do check what level the highest position on the scale gives you if you want really a lot of detail .

Hi all, I´m new here, and i dont really speak good english.
Can anybody tell me where or how I can get/create a geodata.dat file for german-cities?

[Nieko]

AFAIK there's no official German geodata, so your only bet is the Google tab in the geodata part of GMDL. It's rather slow and may block you after a while I think, so not sure it'll work for larger areas.

[zerodays]

Nieko, it seems that, In7ane put default not to zoom more than 6 times.

From my experience fiddling around with Advance setup, I need to set min.zoom to -2
. Then GDML will download up to street-level where I can read the 'numbers' on the road.

[zerodays]

Neiko, one more thing, sorry. I've briefly looked at your scripts.
Regardless, it seems that mapthis only reads the compressed geodata.dat,
Any 'working' structures of TXT files ? All I want is to covert my txt file to zlib, but I do not know the structures, and there are several folders.... (refering to my previously uploaded zip file)

cheers.

geodata.dat consists of several parts.

First there's the header part, which contains info on the blocks. Each block usually consists of data for one zip code. In the header you need 43 bytes per block: zip(5) + lat(4) + lon(4) + state(2) + city(20) + size(4) + offset(4). Note that lat, lon, size and offset are stored as little-endian 4 byte integers. The other fields are strings, null byte padded.

After the header there are 5 pound signs: #####.

Then you get the blocks, which are encoded using zlib. I've put an unzipped block in the attachment, containing all the information for post code 1011 in the Netherlands (the house numbers are fake though). The format is: street,lowest house number;highest house number,(+ or -)longitude*1000000,latitude*1000000.

hi.
i tried to download geodata from germany for address lookup. for testing, i only downloaded 1 segment of 256. for this segment the street lookup works, but there is something wrong with the city names and the postal zip codes. it seems that gmdl has download US zip codes and city names. someone know what i've done wrong? i've read something about "regional and language options" but i can't find the panel to change it. i am using gmdl 0.5.04b. is there also a possibility to change "ß" to "ss" and "ö" to "oe" ... in geodata.dat?
