Satellite pour l'Observation de la Terre (SPOT)-4 images of Floreana (2000)

SPOT-4 20 m resolution images. B1: Green (0.50-0.59 μm); B2: Red (0.61-0.68 μm), B3: NIR (0.78-0.89 μm), B4: SWIR (1.58-1.75 μm). SPOT-4 was aimed at supplying high-resolution, wide-area optical imagery. This was designed to improve the knowledge and management of Earth's resources, detecting and forecasting phenomena involving climatology and oceanography, and monitoring human activities and natural phenomena.

SPOT-4 20米分辨率影像。波段1：绿光波段（Green，0.50-0.59 μm）；波段2：红光波段（Red，0.61-0.68 μm）；波段3：近红外波段（NIR，0.78-0.89 μm）；波段4：短波红外波段（SWIR，1.58-1.75 μm）。SPOT-4旨在提供高分辨率、广域覆盖的光学影像，其设计初衷为提升地球资源的认知与管理水平，探测并预报气候学与海洋学相关现象，同时监测人类活动与自然现象。
