SPOT Controlled Image Base 10 meter (CIB-10)

SPOT Controlled Image Base 10 meter (CIB-10) is a collection of orthorectified panchromatic (grayscale) images. The data were acquired between 1986 and 1993 by the French space agency, Centre National d'Etudes Spatiales (CNES), which owns and operates the SPOT satellite system. The National Geospatial-Intelligence Agency (NGA) acquired this collection of SPOT satellite data for the Imagery for Citizens program, which was designed to provide public and educational access to high quality imagery. The panchromatic images were orthorectified using NGA Digital Terrain Elevation Data Level 1 to remove image distortion and obtain the geometric qualities of a map.SPOT控制影像基准10米分辨率数据集（SPOT Controlled Image Base 10 meter, CIB-10）是一套经过正射校正的全色（灰度）影像集合。该数据集于1986年至1993年间由法国国家太空研究中心（Centre National d'Etudes Spatiales, CNES）采集，该机构拥有并运营SPOT卫星系统。美国国家地理空间情报局（National Geospatial-Intelligence Agency, NGA）为公民影像计划（Imagery for Citizens program）收购了这套SPOT卫星影像数据集，该计划旨在为公众与教育机构提供高质量影像的获取渠道。本套全色影像采用美国国家地理空间情报局一级数字地形高程数据（NGA Digital Terrain Elevation Data Level 1）进行正射校正，以消除影像畸变并实现地图级别的几何精度。
