Hi folks, not sure if this site has been discussed here on the forums anything before.
http://terrain.party/

you select and area and click on the cloud icon to export, and it will gather the data from the area selected, then it compiles it to a zip file with four files, one textfile with info of the heightmaps, then three heightmaps, I suggest to use the merged heightmap as said in the text file.
some of it uses ASter 30m resolution mostly and a mix of others.

quite nice, the only issue I see with it, not always available map in usgs topography maps if you search for areas outside the United states for instance, but you could use the street map..it can be a bit tricky to get an overview of the area in such case, so my suggestion is to have a browser window open with google earth map and find the area ..then try to match the area in the terrain party site view.

I find this easier to get maps from than the large usgs elevation data ..which became more and more complicated to order selected areas.

This is interesting, but too low resolution. It is better to search first for local DEM data on any local cartography service.

Agreed..a bit too low res, only 1081x1081, though it is interesting that you can get hold of pretty much anything, I recall trying to get wadi rum geo locations on the usgs site, but that was even worse or completly lacking the option to get some areas, but with this I got at least something, I also browsed around in new zealand as well and got me so me rohan landscapes from deer park heights, it helps to get an idea and rough landscape..so if One by any chance would need a higher map, you at least can get a decent preview with these maps on how it eventually may look.

2k minimum and 4k is prefered though.

I like that it is so easy to extract maps and download them, as opposed to how usgs has set it up, but a bit too low res at the moment and we are lacking proper topography maps of the whole world in there when browsing for locations.

Here's an 8km "merged" map of Makalu summit region (border of Nepal & China, near Lhotse & Everest) by Terrain.party...

As this is intended for generating height maps for the game Cities:Skyline, I'm not too surprised by the low-res maps (1081x1081). Still, I'll stick to using DEM Earth (https://cinemaplugins.com/c4d-plugins/dem-earth/) on C4D for when I really need detailed terrain geometry and height maps.

thanks for the sample, for me not that interesting map though, too little resolution as said, but it is also very blurred.

will have to take a look at C4D and the dem earth plugin, though it is highly doubtful that I would invest in cinema4 versions anytime soon, but you got to check the options of course.
I wonder..what service is that dem earth plugin connecting to, that delivers higer resolution maps? is that service otherwise payed for? but included in the dem earth plugin payment?
I will also find it interesting to see how well cinema4d VS lightwave next version will cope with displacement maps at very high detail at 4 k res maps and with aroun 6-8 millions of polygons for getting extremly high terrain detail in there..so that is something I will be interested to compare.

I will post some maps tomorrow I think, maybe some northern swedish part of jockmokk..some rohan..deer height park, and something else, sweden is generally quite flat otherwise unless going north or bordering o norway where mountain ridges has been created, so norway may be an area of nice mountains.
I will browse through zealand more as well, scotland is also in the plans for my virtual travelings..since I once saw some very nice landscapes there.

It offers a number of different sources, and access to higher-res data is included in the service price. I actually have an active subscription, so if you'd like me to acquire a more "interesting" sample for you, please ping me in PM and we can work out details of where/what you want (I believe it can even provide basic extruded buildings/roads/etc in v3).


I will also find it interesting to see how well cinema4d VS lightwave next version will cope with displacement maps at very high detail at 4 k res maps and with aroun 6-8 millions of polygons for getting extremly high terrain detail in there..so that is something I will be interested to compare.

Well, C4D's micro displacement is pretty impressive these days, and Vray's even more so. LW definitely has more trouble producing reasonable representations of 4K or 8K maps (esp. 8K), but should still be viable if it isn't something like a major city with zillions of extruded buildings, roads, etc. plus the terrain itself.

That example you posted demonstrates a real advantage of R18 C4D's viewport dynamic GPU tessellation: Where you're working with a 720K-poly object in LW viewport handling terms, I'm working with a 1K-poly object in C4D viewport handling terms (just over 2K polys for entire viewport incl. gizmos, see OGL stats HUD). The GPU then dynamically tessellates the terrain plain (64 additional subdivisions) further for display, but at near-zero polycount-handling cost. Obviously that makes heavily-displaced (esp. sub-pixel displacement) objects so much easier to manage.

Thanks for all that info, and understood, cinema4d probably has a lot of advantages for stuff like this, so no surprise they used it in the Prometheus movie partly for wadi rum locations together with purchased dem data from that area, but rendered with cinema4d, though it took many many hours per frame for the scenes.

Cinema4d will however not be in question until I have checked out the new lightwave version, only then perhaps..and that would assume I could afford it and should afford it ..and wether or not that would be hobby/personal projects or a plan to use for commercial stuff later, meanwhile I will take notice of it all and I thank you John for giving me some overview of that.

Thank you.

Great..now go and extract some nice Norwegian mountains :)..I guess you would need to use both google maps and terrain party since you do not get a topographic map overview unless browsing the us or canada, so it can be hard to find the good spots.

There are two ways to create landscapes natively in C4D (I use WorldMachine Pro and Vue xStream for creating height maps).

You can create a Relief object and simply refer to the height map but this is limited in subdivisions.

The better way is to use Subpoly Displacement in C4D, add a displacement texture to a plane, this renders 8k maps from WorldMachine within 1-3 minutes in FullHD with the standard renderer.

The DEM Earth plugin is simple to use with great results from what I've heared (I don't have it).


Edit: Sorry just noticed JWiede answered this in detail already, yes forgot to mention the new GPU tesslation.

We really need a whole Cinema4D section in these forums. Some valuable information gets lost inside of countless LightWave threads. :)

Thanks prometheus for providing link.
Will check it out as soon as i have time.

Meanwhile here is info about a Landscape plugin for Lightwave that ive have had for a while now which maybe usefull to those who are not aware of it.
The sample image attatched shows an untextured .hgt map of Mount Fuji and surrounding mountains.

Below is all the info i have in a text file about this plugin called
"Ground Control" plugin for Lightwave Cost GBP 25.20 [inc VAT (20%)

Link to site http://www.digitalcarversguild.com/plugin.php?ProductId=7

Ground Control is a digital elevation map importer plug-in with support for classic USGS DEMs, VistaPro format DEMs, World Machine 32-bit RAW FP, Terragen TER files,
Shuttle Radar Topography Mission HGT files, ArcInfo ASCII Grid, text format PGM, and BIL files. GridFloat FLT files are also supported under LightWave.
-------------------------------------------------------------------------

A few links provided to me by Ground Control tech support.

DIGITAL ELEVATION MAPS
http://www.viewfinderpanoramas.org/Coverage%20map%20viewfinderpanoramas_org3.htm

DIGITAL ELEVATION TEXTURE MAPS
http://viewer.nationalmap.gov/viewer/

With the above links and visits to a few other sites i managed to aquired
many different and varied hgt maps from all over the world including specific countries/places id visited in the past.

Just one thing to be aware of if you decide to buy into this plugin.
When you open a folder with maps in especially if its a folder with your own modified maps then make shore you select "Show all files" in the bottom right of your folders
window as your file may not show that it is present.

One other thing thats is usfull to know.
If you have the "AdvancePlacment" plugin then this plugin handles these
large polygon maps with ease and you can paint other objects onto the surface with equel ease.

would be cool to get this detail one day... or even generate it in 3D...

That may be, but from my experience...such heigh detail in terms of undulated areas isnīt yielding interesting landscapes really, as much as cool they are in terms of texture in the area, thereīs to little difference in height and to little empty negative flat areas for it to make interesting landscapes, in fact, not many large areas of mountains make it interesting either...where you actually may get more interesting landscapes by modeling or extracting smaller parts.

yes, but i was more thinking in regard to the dynamic breakup.

i might do a dynamics tests for this one day, just for fun    http://forums.cgsociety.org/images/smilies/arteest.gif :)
