本文基于 Scala 3 与 GeoTrellis 3.7、GDAL 3.8 环境。假设已掌握坐标系统与栅格基本概念,侧重工程实践方向。
处理 WGS84 与 Web Mercator 互转时,投影边界外的坐标容易让第三方库抛异常。不应用 try-catch 包整个流程,而是给每次转换配上退避重试和最大偏移校验,并在连续失败后返回兜底坐标。下面的逻辑用 Scala 实现一组通用重试装饰器。

Если сильно упростить, Jev превращает задачу «сгенерируй JSON» в задачу «заполни несколько заранее известных ячеек».
Обычная LLM делает примерно так:
{→"risk_level"→:→"HIGH"→,→"requires_review"→ …
То есть она пишет весь JSON последовательно, токен за токеном. Даже если структура заранее известна, модель всё равно генерирует скобки, кавычки, запятые, имена полей и значения.
