How To: Generate Superb Heightmaps :)

Re: How To: Generate Superb Heightmaps :)
Hi! I'm a new member here.
I did myself a Jamaica heightmap but there's this tiny problem:
How can I get rid of these gridlines?
I'm sorry if this has been resolved already.

There's so many different worlds, so many different suns, and we all have just one world, but we live in different ones.
Re: How To: Generate Superb Heightmaps :)
I suppose these gridlines are present in your heightmap as well. Care to attach it?
Re: How To: Generate Superb Heightmaps :)
Yup, they are present on the heightmap as well.
I did everything like described, though.

Re: How To: Generate Superb Heightmaps :) - Ugly grids
Ugly grids
Try this one.
Btw.: MicroDem can open and save TIFs, PNGs ...
Does anybody know how to place OpenTTDs rivers by default?
To get DEM-Data to fill Holes (such as Finnland) look at this one.
You get here *.hgt-Files which can open on the same way.
http://www.viewfinderpanoramas.org/dem3.html#scand
For an overview of the whole world as TIF or ASCII try http://srtm.csi.cgiar.org/ (note the password) -> https://hc.box.com/shared/1yidaheouv#/s ... 1/34252608
Try this one.
- Start MicroDEM
- Load DEM-File
- Rightclick on the map and select Grid/graticule
- Select Neither
- Ok

Thank you, Eisenbaehr. That took care of it.

This could be the result of 3 days work with DEM.
Thanks for the Great Work to TT, tutorials, wiki, the forums and much more!

Re: How To: Generate Superb Heightmaps :)
Me again.
This time I have another problem: when I try to merge the thin DEMs together, I can't find 'multiple' choice when I click Merge->DEM. I only get these two options: ADF grids and Geographic blocks. Any help about how to overcome this?

Re: How To: Generate Superb Heightmaps :)
Currently I have no MicroDEM here. Try MicroDEM-Main-Menu -> File -> Open -> Open and merge DEMs

Simplest and most obvious solution. Thanks a lot!

There are some things that have changed since you wrote this
MICRODEM Homepage has moved. You might want to update the link.
You only need the second link and only extract the srtm.asc-file.
When I open Microdem, it wants me to search for the Mapdata-folder, but you cannot browse other drives than C: - you can just abort the search twice and it still runs fine, though.
Tey are yellow house-icons.Click on the Green buttons
There are eight links, all from London.you'll want to download either of the first two links (Either from the US or UK Servers, it doesn't matter)

Re: How To: Generate Superb Heightmaps :)
I've been trying to find a heighmap or the DEMs to make one myself to make a Sweden scenario with a 4096x8192 map size for quite some time but without succeeding. Firstly because most DEM sources (including the ones recommended in this thread) for some reason don't cover the northern 2/3 of the country, and when dealing with large images like that there are memory issues and MicroDEM simply runs out of memory and can't make any heightmaps.
If someone could send me in the right direction (or even better, make a heightmap), that would be very appreciated (and a badass Sweden scenario will be made).

Re: How To: Generate Superb Heightmaps :)
Try to make them as separate heightmap, then fuse them in MS Paint or other.
Eg. If your scenario needs 9 DEM, sort three of them into one heightmap, then do the same for others. Then simply fuse them in Paint. And load in OTTD
(This may cause some problem with trench or others, but just fix them in scenario editor. It is also recomended that you use same values for all of the original heightmap from MicroDEM.)

Re: How To: Generate Superb Heightmaps :)
Yeah I thought about something like that, the problem is also that even finding DEMs for areas above 60 degrees north (which large parts of the country is), when doing something similiar in the past I had a lot of trouble with the maps not syncing correctly, but I guess that can be mended in the scenario editor....

The original DEM-files exists, but the files are very very large (~30 GB, after thining ~500 MB, packed ~50 MB, as png ~3 MB). So I only can make a new png from the DEMs if you wish.
Re: How To: Generate Superb Heightmaps :)
If you could make a png that covers entire Sweden in the size 4096x8192 (or an even larger size&area that I can fiddle with) that would be amazing, and an epic scenario is promisedEisenbaehr wrote:http://www.tt-forums.net/viewtopic.php? ... 0#p1010797jostor wrote:...Sweden ... sources ... don't cover the northern ....Eisenbaehr wrote:...

Re: How To: Generate Superb Heightmaps :)
Do you asked the autor of this scenario to get the png?
http://bananas.openttd.org/en/scenario/
-> http://www.tt-forums.net/viewtopic.php?f=60&t=44921
Maybe he has the original DEMs too.
To create a png for you it is better to have a correct rotated and sized preview to know what do you want. By rotating the map to the north you will have many "waste" from the neighboring state.
Watch the Europe-png. The African-area is very big (and with snow , but this was the price to get Spain and Greece.
Next the result should be ready sized to your favorite width/height to avoid sizing by OpenTTD and loose islands.
Even the DEMs must thinned in the beginning to avoid memory overflows. By executing this task it loose many details. That's why I ask for an preview of your favorites.
Also to know the highest mountains and the amount in the game is really important. Otherwise the map is to low or some mountains are flattened.
I will try to make a preview.
Can you open an own thread for this task?

Re: How To: Generate Superb Heightmaps :)
@ Eisenbaehr : In that case, he only need to save the .scn into heightmap... and load it in a larger size No real need of permission, most can do that themself.

Re: How To: Generate Superb Heightmaps :)
Oh of course. I forget it. Is there another way to extract the heightmap from the scn as to load the scn and save this as heightmap?

> Sweden in the size 4096x8192
Do you ever placed cities, rivers, industries on such map?
It is very hard to find bottom and top on this map.... That's why I ask.
The attachment is the half of your favorite size (4096x2048), rotated by 45° to get the north in the north... maybe I can make also an 8192x4096 PNG to get more details. If you wish you can load this PNG as 8192x4096. But the maps maybe looks like tetris.

Re: How To: Generate Superb Heightmaps :)
Yeah I know 4096x8192 is very large. I'm currently playing a 4096x4096 map of southern Sweden (the parts I could find easily and use without crashing MicroDEM due to memory cap), and 4096x8192 would just be with the northern part too, I like large maps, that way I can include the commuter trains, and not have stations as long as entire cities
I don't mind if the map isn't turned 45 degrees, since it includes a lot of things on the sides that isn't really needed, in fact it probably makes it better since the space can be used a lot more efficient.. I'm used to playing with the in-game north west being the real world north.
Also, I don't know if it's possible to do something about, but that heightmap puts a lot of the country that is above sea level as under water (literally half of southern Sweden is under water with that heightmap), making it a big job to fix (especially on an even larger map), it would also be good if the mountains in the north are even higher to represent the real difficult of building around them
I know this sounds like a long list of requests, but you have no idea how much I appreciate this work

Re: How To: Generate Superb Heightmaps :)
@ jostor : I hope that you can overcome the very-huge-map with detailed cities and industries.
@ Eisenbaehr : No more way to extract heightmap from .scn file. Not that I know exist in OTTD nor outside of it.
