# Third-party software notices

The project depends on third-party npm packages whose own licenses apply. This
file records the packages added for the browser-local SDR feature and the
Street Level viewer, and the CesiumJS code ported into `src/geo/`; the complete
resolved dependency inventory remains in `package-lock.json`.

## CesiumJS (portions ported to src/geo)

- Package: `cesium` 1.138.0 (`@cesium/engine` 22.3.0); the files in `src/geo/`
  are adapted from `@cesium/engine/Source/Core` (`Math.js`, `Ellipsoid.js`,
  `scaleToGeodeticSurface.js`, `Cartographic.js`, `Cartesian2.js`,
  `Cartesian3.js`, `Matrix3.js`, `Matrix4.js`, `Quaternion.js`,
  `Transforms.js`, `BoundingSphere.js`, `EllipsoidGeodesic.js`, `JulianDate.js`,
  `Simon1994PlanetaryPositions.js`) and say so in their first
  line. The changes: the classes' static functions became module functions,
  vectors, geodetic positions and quaternions became plain-data instances of
  module-private constructors (own enumerable fields only, no methods),
  matrices plain arrays, and the ellipsoid a frozen object; the debug
  argument checks were left out, as in Cesium's release build; only the subset
  gev uses was kept.
