Hi Dev Community! 👋
I've been working on an open-source project called Locus-Earth recently. It's a lightweight, browser-based interactive 3D Earth built with CesiumJS.
Instead of just dropping a link, I want to share some features and the development process behind it.
✨ What's new in the recent update?
- Multi-basemap Switching: Sentinel-2, Blue Marble, night lights, TianDiTu, Tencent Maps, etc.
- Interactive Tools: Distance/Area measurement (snapped to terrain), markers, and browser-local favorites (import/export supported).
- Location Search: Just type a place name to fly there.
- Scene Integration: Auto high-precision city models when entering Denver, Washington D.C., Sydney, etc. Street View appears when entering mainland China!
- UI/UX: Day/night lighting, white model toggle, dark/light theme, compass, draggable floating toolbar (adapted for mobile).

Special Thanks: Tencent Street View uses a community-maintained third-party viewer, qq-map, to open panoramas (not an official Tencent service). The coordinate transformation logic can be found in js/coord-transform.js (two-way conversion between WGS-84 and GCJ-02).
