Need help to make .dem/GeoTiff file to minecraft world

T

Hey there. Some weeks ago got an idea to remake my hometown in Minecraft. First I did so by hand, but I quickly figured out that it took too long and it would probably not be so precise.

Then I looked around the internet and I found out about .dem and GeoTiff and how to make these into a 8 bit greyscale map, and making this into a Minecraft world. But after a while I figured out that it wasn't precise enough either.

Then after some more thinkering I got the idea "What if one could take a GeoTiff or a .dem file and directly make it into a Minecraft world?".

I googled about it, and then I found that there were someone who already had the same idea that I had, and made it possible!

Now this is where I am stuck. The guide How to make Minecraft worlds uses a .Tiff file, which doesn't seem to work with my .GeoTiff/.dem files. I don't got enough experience to know how to do it, so as eager as I am to make this a reality, I come here asking you for your help.

Some info about my hometown.

The highest mountain is around 1300 metres above mean sea level.

The location is on the west coast of Norway.

The .dem comes from "kartverket"

 

I've uploaded the files in a .rar file format here:

The .rar file includes a GeoTiff file, a .dem file and a close zoom at my hometown.

I hope for the best!

Hi - I can certainly help you but in the short term a quicker solution might be this service here:

http://minecraft.kartverket.no/

It's a service where you can specify an area of Norway and download that area as a Minecraft model. It's driven by FME and possibly may use the same kartverket data that you are trying to use.

I hope this is useful. If you do still want assistance creating your own model, then please let me know!

We have an example using Kartverket data here:

It uses Lidar data, with DEM it is even easier - just make sure that the cell spacing is 1 meter and then you can make a point cloud, which can be save as a Minecraft world. Of course, you should set blockID and blockData before writing it (either PointCloudComponentAdder or PointCloudExpressionEvaluator).

Still, you will have to make it 8 bit - this is defined by Minecraft elevation range from 0 to 255. This works okay, if you scale your world down, which usually makes sense.

I looked into that, but I didn't mention it. The world looks very good with all the roads, rivers and lakes marked, and the width and the length is accurate, but the height is not. it seems to "flatten out."

I've uploaded some images in a .rar format. it includes images of my town from different perspectives, and a comparison between kartverket's generated world and one from a greyscale.

Yahoo!! I managed to get the .dem file into minecraft with better detail than a greyscale one!

On the kartverket's minecraft world creator. they included things like river, lakes and roads, but they seem to be in the SOSI format. How can I use these in femdesktop?

Also another issue has come forth. My hometown seem to be on the corner of 4 .dem files. how can I combine these into one in fmedesktop? (Solved with RasterMosaicker)

This is how my fmedesktop looks like now:
