Forums → Request help or feedback → Request help/Generated Topography

I have been working on procedurally generating topography and have reached a point where unbiased perspectives and feedback would help. I’d like to know what doesn’t look right, what could be improved, or if there are things that I have I missed or forgotten to consider.

Information about the process along with territory examples can be found at this link.

This is insane!!!!! How long did it take to make this? MiniMapper (talk) 03:17, 13 January 2024 (UTC)

Absolutely great work, I can't wait to see more. Did I get it right that rivers are added by erosion techniques after the elevation map was created?--Mstr (talk) 14:14, 13 January 2024 (UTC)

I've been working on this for about 8 years!

The water traces show where water would naturally flow. A drop of "water" is put on every point of the height-map, and then moved to each lowest adjoining point until it reaches sea level. The intensity of the water path color goes up as more drops flow over points on the height-map. This all happens after erosion has already been applied. It also works without erosion. If the volume of the "drop" has a real world value, it would make it easier to see if the water trace was an actual river, or just a stream.Egen (talk) 17:18, 13 January 2024 (UTC)

Hey Egen. I've always been intrigued to see what you could achieve with this, ever since we first discussed some years ago. However, reading your webpage, I have more specific questions. I feel like I'm missing something: what tool are you using to do this? I mean the generated heightmaps. What format are the heightmaps stored in? (I'm assuming NOT SRTM, but if it were, or something convertible, I'd be very excited.) Are you using some specific set of plugins for JOSM (beyond piclayer)? Are you editing the heightmaps in JOSM? If not, are you editing them in some other tool? If not an editor, are you piping your heightmaps through some kind of batch program? I don't feel like these things are obvious from your write-up.--Luciano (talk) 21:07, 13 January 2024 (UTC)
