SRTM3 MakeAHMap discrepancies

Interesting, I see that another folder on my HD has .gz files and it's the same size. This folder is also 3.73GB

This one is very problematic... so HTC can't mirror them.

If we will not find SRTM3 I'll probably need to add a support of SRTM1... maybe convert it to SRTM3 format.

Keep in mind that my files were download directly from either NASA or USGS using your program, they predate CGIAR and are without CGIAR "upgrades."
No need I know of to reference them, especially as they are no longer available in this form.

Isn't there an organization that archives every public webpage ever published? I can't think of their name atm.

The problem is I'm not sure their license allows to be mirrored/used.

WebArchive - they don't collect zips :-( already checked

is it worth getting our hands on older files and just storing them on a server somewhere. as long as it works, it doesnt have to be the best resolution. id rather be able to build stuff that might not be perfect, but is buildable even if slightly flawed

I updated download sources with new SRTM3 mirror. You can download it from there:

https://raw.githubusercontent.com/artyom-beilis/makeahmap/master/download_sources.txt

There is still no solution for SRTM30, so if you need something above N60 you need to use GTOPO30.

[captain1ma]

yay thanks artik. your program is great, it just sucks that they keep changing the sources. im going to try to download all the sources and then atleast have them locally!

[JimmyD3]

Is there any update on data sources? I can't even get GTOPO30 data now. 

[artik]

Are you sure?

I checked the link and gtopo30 seems fine. It seems we are missing only srtm30

BTW. @hitech what about the mirror?

It isn't something complicated to do. If the data will be gone I don't know what will happen with terrain generation?

Virtually all terrains now start from it

For 38.16N, 109.52W, using the download_sources from the link above, SRTM3 is not working for me.  Am I missing something?

[artik]

Show me the log. What the program prints?
Also need map size and scale in addition to coordinate

Kong, here is the latest download  source file I have from artik. It has a different GTOPO30 source than what you are using.

[popeye]

Thanks Kenai.  I get the same result with the download source file that you attached.

[JimmyD3]

Dang, I guess we have to leave it with artik to resolve. Have you had any feedback from Hitech on the maps?
