sure. it will be possible. or at least it will be a good start in reaching to your wish list. I think that I can write a program to grab the wanted part of monitor. and if it worked fine we may add other features to it too.
It would be much better If was possible to have the dear Kruch opinion on that too, before trying to write it. I may write it in Win2000 env. and i think it may work in similar environment. May you tell Kruch too. I may go today , but will see tomorrow again. nice speaking with you.

[quote="Lakva] Well, Sinanmerjan, Kruch detected the adressing scheme for tiles. There are some directiories and then a filemane as 139_23.Gif i.e.
[/quote]

I could`nt understand where those some directories and the file are Sad

[quote="Lakva] At the first step: may you code a program for downloading tiles in mentioned structure? Probably generic will be better, usable for others too. Something for tiles as <domain and directories><file prefix><X><divider><Y><sufix><extension>
where X and Y are in some intervals...
What do you thing?[/quote]
and again I was not able to understand what may I do Sad

shame to me but I really became confuse of what is needed. please let do that step by step and also let`s have Kruch certificate for each one too, since we want them be useful for TB users as tools, too.

Máš pravdu, padesátky a pětadvacítky na quicku vypadaj velmi dobře!!!
Co to Tvoje udělátko? Je to použitelný pro lib. měřítko a oblast?(samozřejmě pokud mapa exist.)
A... zkoušel jsi to kalibrovat? Když se to nakalibruje podle jinýho serveru do Ozi, je to potom přesný?
Moc díky za inspiraci Smile

mapy.quick.cz are really nice, but image addressing is pretty cryptic Confused

for automated downloader...

eg.: http://mapy.o2active.cz/Map?STATE=FMRv7j4eSAEVAAAAAABq-EABAA__&PROFILE=QUICK

Guys, can you summarize requirements for a tool you have been discussing here? I'm not fully tracking this topic..

* First, what is it supposed to do?? Detect map projection when unknown as the topic name suggests? Or also download maps from onli ne sources for offline use? If so, then:

* Second, what map sources it should support? Wouldn't it duplicate capabilitis of other tools?

hallo
I have tried to calibrate some old scaned maps but that maps are not compatibile with WGS 84 datum. I put 4 calibration point in each corner of maps but deviation is about 500 m. I know that I have to use Transverse Mercator projection and I found parameters for my country but I do not know how translate that parameter from old maps(deg min sec) to format for gps.Is there any converter for that?

If you know original map datum and projection parameters, conversion is probably not needed, you can use custom datums in TB.

Guest, I have got XLS table to convert datums. Write me your e-mail adress via personal message or ICQ, I'll send it to you.

Hi Lakva,
Using converter is some option, but using correct datum is better think, if possible. WGS84 ellipsoid as universal worldwide one, have some disadvantages on old maps, often local datum better represents local earth shape. If, in addition, map have distance grid, after conversion it is unusable.
So quest should decide which way is better for him.
