Landsat Missions

The Web-enabled Landsat data (WELD) project combines geophysical and biophysical Landstat data for the purposes of long-term preservation and monitoring of national, regional, and local data. WELD products are already "terrain-corrected and radiometrically calibrated" so as to be more easily accessible to researchers.

网络赋能的兰斯达特数据（WELD）项目整合了地理物理和生物物理的兰斯达特数据，旨在实现国家、区域及地方数据的长期保存与监测。WELD产品已进行“地形校正和辐射校正”，以便于研究人员更便捷地获取。
