SMEX03 Landsat Thematic Mapper NDVI and NDWI: Oklahoma, Version 1

This Normalized Difference Vegetation Index (NDVI) and Normalized Difference Water Index (NDWI) data set was developed from Landsat 5 Thematic Mapper (TM) data for use in studying land cover features during the Soil Moisture Experiment 2003 (SMEX03).本数据集为归一化差分植被指数（Normalized Difference Vegetation Index, NDVI）与归一化差分水指数（Normalized Difference Water Index, NDWI）数据集，其基于陆地卫星5号主题制图仪（Landsat 5 Thematic Mapper, TM）数据构建，用于2003年土壤湿度实验（Soil Moisture Experiment 2003, SMEX03）期间的土地覆盖特征研究。
