Built something with OpenZenith? We want to see it. Whether it's a custom map visualization, a mobile app, a research tool, or an integration with another platform — share it with the community.
🗺️
Maps & Visualizations
Custom web maps, dashboards, terrain renderings, 3D flythroughs, or any visual project using our elevation or tile data.
📱
Apps & Integrations
Mobile apps, desktop tools, CLI utilities, or plugins that query the API or display elevation data.
📊
Research & Analysis
Scientific papers, environmental studies, geology surveys, or academic projects leveraging the dataset.
👨🎨
Tutorials & Guides
Blog posts, YouTube videos, notebooks, or documentation that helps others use OpenZenith.
const res = awaitfetch('/api/elevation?lat=48.8566&lon=2.3522')
const { elevation } = await res.json()
Python
import requests
res = requests.get("https://openzenith.cyopsys.com/api/elevation",
params={"lat": 48.8566, "lon": 2.3522})
data = res.json()
print(data["elevation"]) # 35

OpenZenith runs on Cloudflare's free tier — no servers to maintain, minimal monthly costs. Elevation tiles live in Cloudflare R2 (~1.7GB), API responses are cached at the edge, and everything else executes in your browser. That keeps it free for everyone, but it also means we're limited by what edge functions and client-side compute can do.
D
Dedicated Hardware
Run heavy data processing (viewshed analysis, water flow simulation, slope computation) on a real GPU server instead of trying to do it in your browser tab.
S
Self-Hosted Services
Deploy our own ADS-B receiver, AIS antenna, and weather stations for live, local data that doesn't depend on third-party rate limits.
M
Mapping Tools
Build proper elevation profiling, contour generation, flood simulation, and terrain analysis tools that go beyond what edge functions can handle.
U
User Accounts
Save preferences, bookmarks, and custom maps across devices. Higher API rate limits for registered users. Requires a database and auth infrastructure.
F
Further Development
3D terrain flythroughs, real-time hurricane spaghetti models, vessel tracking, and all the features we have planned.
Every contribution directly funds hardware, data processing, and new features. No middlemen, no platform fees — just geospatial tools that keep getting better. User accounts and persistence are on the roadmap once we prove out the platform and understand what people need.
