Hello,

After i read the topic "Some European cities satelite photos" yesterday i
had the idea to search for terrain data that is offered by my country 
(Germany).
I found the following pages of the German Federal Agency for Cartography and 
Geodesy:

Here are the links:
http://www.geodatenzentrum.de/geodaten/gdz_home1.gdz_home_start?gdz_home_spr=eng&gdz_home_para0=gdzintranet
and
http://www.bkg.bund.de/index_english.htm

Here you can get all kind of maps, including  Digital Terrain Model data maps 
(vector data maps similar like vmap) of Germany.
Those maps are available in different quality steps.
>From 1:25000 to 1:1000000

One example:
http://www.geodatenzentrum.de/geodaten/metainfo.meta_start_dataset?dat_datasetid=528&c1=1&kz=0&keyid=0&inf_sprache=eng

>From that page:
-----------------------
The Digital Terrain Model 50 M745 describes the terrain forms of the Earth's 
surface by a point set that is georeferenced in position and height  and that 
is arranged in a regular grid.

The grid width for this model with mean resolution is 1" x 1" (about 30 m x 20 
m) in geographic coordinates.
---------------------------
Scale band 1:30 001 - 1:75 000

Here's an example test data picture (Digital Terrain Model 1:50,000 M745 - 
DGM50 M745)

These are very exact maps it would be great if we could use them for 
flightgear.
The problem are the distribution conditions, "normally" (general usage 
conditions) those maps cost money. :( 


But on the website there is a section called "Prices and delivery conditions"
at the moment this part of the website seems to be down. :(
It is linking to another website 
http://www.ifag.de/GI/Produkte_lief/Lieferbedingungen.htm
and this host www.ifaq.de seems to be down maybe it is up and running later.

The point is, i visited this page some weeks ago
and read something about exception conditions for public none commercial use.
>From what i remember there was a sentence that said that
for special usage conditions (like the use under the GPL which is public but 
allows also commercial use) we should ask.
 
So perhaps we could politely ask them, if we can get some small data amounts 
for free for a public project like flightgear.


Here is the contact page (the url is very long so i used 
makeashorterlink.com):
http://makeashorterlink.com/?Y22D12B95

To be sure we could wait a little until this www.ifaq.de host is up and 
running again to read the rest of that section "Priced and delivery 
condititions".



Best Regards,
 Oliver C.
