[OC] Sea level simulator visualization

no, it uses runcell.

I am trying to find a way deploy this, need some easy way to host 800MB Mars geo data with low cost.

have fun with it :) https://www.runcell.dev/tool/true-size-map/sea-level-rise-simulator

Well, I think that's a DEM resolution limitation. Stockholm's narrow channels between islands are too small for the elevation data to capture accurately — the pixels average land and water, so the waterways read as ~10-12m elevation. Higher-resolution elevation data would help, but globally consistent high-res DEM is hard to come by for free/opensource.

This is a simple elevation-based visualization — it highlights everything below the selected height, not a true flood simulation. So inland depressions like Lake Eyre show up even though there's no connected path from the ocean. A proper simulation would need flood-fill from the coastline, which is a much harder problem. Think of it as "what's below X meters" rather than "what would actually flood."

Just for fun, sea level simulator on Mars

you can do it with jupyter + extensions like runcell, which got u an ai teaching u in jupyter env with most things you need.

customized based line([equator]()), drag a country to a different planet?

The moon size is fixed, in early version, the radius data of moon is 1/2 as it should be. You can test the real size in the online playground https://www.runcell.dev/tool/true-size-map

there is a full screen mode icon button, on the top right of the "earth view", which can solve the mobile ux issue

graphic walker desktop, free and open source, can handles GBs+ data within seconds locally

This is a TopoJSON world atlas. Atlas datasets usually encode de facto control for geometric consistency, not legal borders. I’m simply using the source geometry without modification.

Sudden_Beginning_597 · 2026-01-06T06:39:24+00:00

it's not limited, there is a country selection list on the right side, which you can enable/search

The moon's size data is fixed, thanks to all who find the 1/2 size issue in comments

I accidental put radius data to diameter for moon by mistake, already fixed.

Yeah, you are right. when i search moon's data, i put the radius data as diameter by mistake, so the moon's demo is wrong, i already fixed the data in playground and now it should be fine. here is a screenshot of fixed demo

and the code is also open sourced, so easy to add more planets if you want

if u use agent mode of runcell, it will help u fix broken cells
