等面积球面GPS坐标生成器
在地球3D球面上生成真正均匀分布的随机地理坐标，彻底消除两极聚集失真。
⚙️工作原理（算法与方法）
Flat rectangular coordinate algorithms pick latitude uniformly between -90° and +90°, causing points to cluster unnaturally around the poles where circles of latitude are tiny. Our engine samples the sine of the latitude uniformly: lat = asin(2u - 1) * (180 / π) and longitude = -180 + v * 360, where u and v are independent uniform random variables in [0, 1). This ensures every square kilometer on Earth has an identical probability of selection.
lat = asin(2u - 1) · (180/π) | lng = -180 + 360v | Area Density: dA = R² cos(θ) dθ dφ✨核心功能与特性

仅限陆地拒绝采样引擎
过滤71%的大洋水域，确保生成的坐标全部位于大陆或岛屿陆地上。
⚙️工作原理（算法与方法）
Because 71% of Earth is ocean water, generating points at random will hit water nearly 3 out of 4 times. When "Land Only" is selected, our system generates an equal-area candidate point and performs fast polygon bounding-box vector tests against Natural Earth continental polygons. If a candidate point lands in open water, it is instantly discarded and regenerated within a microsecond safety budget (up to 250 iterations).
