Zipped BMP file (8MB for the zip, it generates a 1.1GB BMP)

Just FYI I have been working on a (at present) Windows PC based map generator.

I have just successfully generated my first TOG creative server map image file (thanks to Thermal for providing me with the map data) and I am uploading it to my web host.

The image is an overhead view, minus trees, tracks, etc at present. It is basically an overhead of ground level. It is a windows bitmap file format (I know, not ideal, and I will generate something else later) and is 36MB in size.

The map is 1 bit per block with a particular color palette. Most of it is obvious - though the brown for dirt looks more reddish than brown.

The map currently has 332,999 chunks and takes about 90 minutes to generate at present (down from 180 minutes at my first try) on my reasonably up to date laptop.

Any comments on the map contents are appreciated, but it seems pretty accurate as far as I can tell. I will post a link when it is finally uploaded.
Cheers,
Cheith.

PS: from looking at some newer maps it would seem that Notch's terrain generation algorithm has some new 'features' and some new generated chunks do not always seem to have the borders between terrain types that you would expect.

His terrain generation algorithm is 1 nice piece of work, whether its his creation or that of another code, its quite a nice utility

Actually, if you have an overhead map view of newer maps, you will see that it does some odd things these days for boundaries between sand and grasslands, for example. It is almost as though he has forgotten how his chunk coordinate system works. Coastlines are usually okay though.

Didn't you say it was 36MB? I just downloaded 1.1GB! I thought it was a bit slow

Oops, sorry, so it is. I must have looked at the wrong thing or something.
I will generate a jpeg later today or tomorrow.

Here is a link for a windows zip file that is a lot smaller:

Its a BMP file, BIT MAP, there is no compression, its more like a raw image format, JPG or PNG (slightly better compression) will give you a MUCH smaller file
The previous PNG by Mr Ions in PNG format is compressed, get the details of the image after it has been pulled into your favorite image viewer program, its actually quite HUGE

Actually, I thought 36M for a BMP file was either low res or a bit small, 1G sounds about right for the area of land we have

I think from my perspective, this is acceptable

the data your using is quite old by now, North is up

I'd love to see the nice radial arc I have on the left of the map

I wanted to download the map from my private server to something viewable on google maps. What program will convert the .dat to that format?
