After seeing the amazingly huge maps generated by Minecraft-Overviewer I decided it was the best mapping program for my needs. I've installed Python 2.6, PIL, and Numby as per the requirements listed on the website, but I need a little extra help getting it to run. I've searched around the internet but was unable to find any tutorials for this particular program.
I have downloaded all the files in the minecraft-overviewer directory from the project page, but I'm not sure where they need to be placed and exactly what steps I need to get gmap.py to run. If anyone can point me in the right direction I'd really appreciate the help.
You need to open a command line and run the program with the arguments described.
The instructions are almost good enough, but not quite for the complete Python novice like me. I know how to use a command line, but the gmap.py command will not run because I'm not sure where the files need to be placed and how to get Python to recognize the command. I'm sure the solution is very simple, I just need a brief step by step walkthrough from someone who knows how it works.
Okay, so apparently this program does not require Python or anything else that the web page says it requires. Just download and run from the command line.
I am a complete noob on Python, and I do not understand how to get this to work. Can someone go through EVERY step to get this to work?

Of course, if you see Biendeo anywhere else, that's probably me.
No problem. As I mentioned you do NOT need to install Python or anything else. Go to the Minecraft-Overviewer website and click on the button that says downloads. Now download and unzip the package labeled 0.0.3 or something like that. For simplicity's sake I also copied my "World1" folder (or whichever world you want) into the same directory as the Overviewer, although this might not be necessary.
Open a command prompt in Windows (open your Start menu and type "command prompt") and navigate to the Overviewer directory that you just unzipped. You can do this using the "cd" and "dir" commands that you can figure out on your own. Your location will probably be different than mine.
Now in your command prompt, type "gmap 1 testdirectory" and it should begin processing. Replace 1 with your world number and testdirectory with the name you want for your output directory. That's it, you're done. If you want to add options just look at the list on the webpage or run "gmap" with no parameters.
Maybe the author will update the instructions on the website at some point to be a little clearer.
I've rendered the chunks however I believe I'm receiving an error:
Trackback <most recent call last>:
File "Chunk.pyc"
.....
...Several files are listed
.....
IOError: Not a gzipped file
What the heck is going on? I'm not receiving an files into my cache directory nor any testdirectory/world directory....

Are you sure I can just run gmap from the CLI without having Python installed? I tried and (not surprisingly) "gmap" wasn't recognized as a command.
Right now I cannot install Python in this machine to give it a test but I will from home. However, I'd like to know if there's an executable or standalone version of this, so that you just run it from the command line in Windows.
The 0.0.3 package downloadable from the website comes with the standalone windows executable. I tried this on a machine without Python installed and it worked.

Any thoughts?
Same as above, I get the same error. Maybe we're missing something? I'm running a server with hey0's mod on WinXP32.
Below is the output I get, hope it helps. What I observe is that some chunks are rendered ok but at some point it encounters invalid files (not gzipped) and stops. The tiles are generated in my designated cache folder but obviously the final map with the index.html is never generated. It's like some files of the world are gzipped and some others aren't. I thought about "gzipping" the ones with the error, but as all of us know, the world folder is an endless trees of subfolders.
As a test, I tried to render one of my single player maps (about 1000 chunks) and it ran flawlessly, generated everything and stuff.

Hmm, I haven't received any errors like that before. It's possible you are doing everything correctly and there is simply a bug in the program. You may want to try going to the developer's page and posting this issue (I think you have to sign up to post).
I'll post the problem on the developer's page and see the feedback, I'll come back when I have some solution to share here. It seems a pretty isolated problem, since the only place I found a similar report was here.
That sounds good. It's a shame this great program seems to have very little community support and information available. I'm hoping the developer will eventually add a GUI and some more output options. The google maps format really is the best way to browse a large Minecraft map.
Well, good and bad news. As in every case similar to this, the Windows binary package of the program isn't up to date with the source version.
The good news is that the error got fixed in a later version for which there isn't an exe package yet, so the bad news is that I'll have to install Python, PIL and Numpy in my server and use the latest source version. Another solution would be to remove the corrupt chunks generating the error, but my head starts aching just by thinking about doing that.

Thank you, I kept putting [options] into the command line. The instructions just weren't written clear enough. I also kept trying variations of world 1, 1, and world1 because it was complaining about there not being a directory.

Hey, guys.
Beta = released to the public.
Minecraft Alpha is Beta.
And don't turn this statement into an argument, please.

Once you stop riding him he can try to blow you again.
I think I found a solution to your problem. I was typing "gmap 1 test" and received errors. After trying "gmap world1 test" it started rendering. It's working as I post, I'll let you guys know if it's successful.
It's telling you that it can't find any map chunks, which means your either not typing the correct directory or that you've updated your server to 1.3 and it has converted your map.
