@ in7ane:

Decrypting/cracking geodata of the Netherlands wont be a big issue I think :P
The Dutch government is gonna release it all in 2009 to the public, but well, we psp guys cant wait that long :P

Ok MAJOR BIG NEWS onto Geodata

I talked to the guys of Openstreetmap. They provide free geodata from all over the world. So far 5% of the whole world is covered. Ok that isn't much but remember it's a freeware non-paid project with just 30-40 volunteers.


This is how to grab geodata for you city:

1 Download the whole planet from http://planet.openstreetmap.org/ Download the one low on the list, so that you have the newest data (don't pick 2006 )

2 Extract it, it becomes 4 gb !!

3 Download the extracting script: svn.openstreetmap.org/applications/utils/planetosm-excerpt-area.pl
or svn.openstreetmap.org/applications/utils/osm-extract/planetosm-excerpt-area.pl

4 How to use the perl script: planetosm-excerpt-area.pl -bbox 54,-1.5,55,-1.4 planet.osm.xml > excerpt.osm

====================================

Remember to: install several perl modules and play with the lib path

Disadvantages : Getting a lot of invalid line errors, but i'm not using a planet.osm.xml

======================

And since AND donates the Netherlands which is 100% complete, you have good geodata. More countries will follow !

Good luck with it In7ane and others !!!

In7ane, i have some Geodata for you. It's in DBF format, maybe you can do something with it.

I tried to convert it to CSV or Excel but it failed.

It's for many country's. Latitude/Longitude is provided, even as NMEA data.

Hope it helps. It's all i can do for you at this moment.

I converted it into csv but cant get it to work in gmdl. Maybe convertion sucks but.... I'll keep trying :P

Here's the csv file of the netherlands I converted.

Falafelut2k4 and others

The Netherlands Geodata file is very weak. It contains only a few cities. Good job you converted it but now it contains an error

This is what the colums mean if you open up the file in MS Excel:

A : Country
B: Country sign e.g US for United states, here it is NL
C: Postal code and telephone prefix
D: Postal code
E: City name
F: Part of City
G: Nothing
H: Lat min
I: Lon min
J: Lat max
K: Lon max
L: Unknown
M: Unknown
N: Unknown
O: Unknown
P: Unknown
Q: Unknown
R: Unknown
S: Unknown
T: Countryname
U: Unknown
V: Location of city (north east south west)
W: Unknown
X: Province
Y: Unknown
Z: Secondary name of Province (e.g Las Vegas is in the Desert )

But it's all i could find free legally available. Soon i can get a 700 mb file of the Netherlands which contains all streets etc.

That will be in 3-4 months. AND must first donate the data to Openstreetmap.org, then they must implement that and after that i will have to learn how to extract it from the 4gb datafile as i posted in my tutorial up here.

I can't get the Perl script to work, In7ane can you help ?!

[in7ane]

As falafelut2k4 says - it looks like there's only regional information in the DBF files (FoxPro will open them if anyone wants to take a look).

Codaz, I don't know Perl so I can't be much help with the scripts. I've done some stuff (creating from the Canadian road network) with OSM files, and as I recall they are sufficiently straightforward to write your own parser that would process/load the planet.osm line by line (I doubt that a 4GB xml file can be loaded into memory at once). If you are going to write a OSM -> geodata load, keep in mind that it's something that should be reasonably easy to rerun every few month as more data is added to openstreetmap. Alternatively I can try and get around to doing it eventually, if so, does anyone see any reasons for not loading the OSM into Oracle as an intermediary step? And, any ideas on how to do city/province/country names (I think the OSM file will just give us road names and lat/lon, not what region it's in or house numbers).

Can you tell mi how I can calibrate custom maps ina GMDL and how to use "Comparsion source" in custom map window or can you give me link to post which can help me.
Thans a lot

[Codaz]

In7ane,

Too bad you can't help on Perl scripts. But it's VERY good that you already worked with OSM.

I see no complaints to port it to Oracle first, you guys ? Go ahead with it If i knew Oracle i would help you out.

Second question, i provided the DBF files which are a bit weak, Falafelut2k4 tried to convert them to CSV as you asked.

Any luck with them to work them out in GMDL ?

Because there isn't a way to proper import CSV data into GMDL ?

It isn't that hard to implement it i think, but you have to have a proper format in which the CSV files should exist, that number of colums providing that info. Otherwise the CSV file is useless. It is too hard to program a feature into GMDL which calculates the needed information from a CSV file. Especially when the CSV file is very large.

So to be short, are you working on a definitive way to implement CSV into GMDL or something else ?

Hi.
It is ok now i just update the windows framework.

[in7ane]

Bumping up to 0.4.17b due to changes in maps.local.live and to draw a line under various other small changes.

http://www.in7ane.com/psp/gmdl0.4.17b.zip

Full list of changes from 0.4.16b:

Fully decoded Swedish geodata
Google directions option to avoid highways (multistage, and manually dragged directions work as well)
Toporama auto render now uses the latest version of MapCruncher, and allows to specify a drive other than C to look for it
Option to convert tiles to JPEG while downloading (but you are much better off using GPSFS_util by MIB.42)
Sounds are on by default (directions), see .zip in GMDL for mac scripts to create message mp3s
Custom geodata (from a CSV file), now with ; delimiter support
YUM Assembler for MapCruncher (contact me if you want a walkthrough) - see: http://www.in7ane.com/psp/posts/yum_assembler.jpg
Option to save directions at various encodings and UPPERCASE (eg. Default and UPPER for the Russian Map This!)
Changes to keep up to date with the maps.live.com update


icpart, the best way is probably to use MapCruncher (free from Microsoft Research), GMDL can then use it as a source: http://en.wikibooks.org/wiki/Map_Thi...MapCruncher.29

Codaz, I'll make some more tweaks with the CSV import (it will work with large files right now, but creating them will be the problem). Ultimately getting the OpenStreetMap planet.osm data processed looks like a better idea - so that'll be the main geodata focus from now on.
