NICFI 卫星数据计划镶嵌图（也称为 Planet-NICFI 镶嵌图）包含每月和每半年生成的半年期集合。镶嵌的类型存储在图片元数据字段“cadence”中。使用该字段以及每个镶嵌块的开始日期和结束日期来查找所需的影像。
有关基本地图的完整详细信息，请参阅 NICFI 卫星数据计划基本地图规范。
如需详细了解 NICFI（挪威国际气候和森林倡议）卫星数据计划及所提供的数据，请访问该计划的网站。
为了支持 NICFI 的使命，您可以将这些数据用于许多项目，包括但不限于：
- 推进有关世界热带森林及其提供的关键服务的科学研究。
- 在热带森林发展中国家和管辖区实施并改进可持续森林管理和土地利用政策。
- 提高热带地区的透明度和问责制。
- 保护和改善热带森林国家/地区的原住民和当地社区的权利。
- 创新解决方案，以减轻全球商品和金融市场对森林造成的压力。
