SMEX04 Land Use Classification Data, Sonora, Version 1

Notice to Data Users: The documentation for this data set was provided solely by the Principal Investigator(s) and was not further developed, thoroughly reviewed, or edited by NSIDC. Thus, support for this data set may be limited. This data set is comprised of land use classification data necessary for modeling and scaling hydrologic variables as part of the Soil Moisture Experiment of 2004 (SMEX04). Six Landsat 5 Thematic Mapper (TM) scenes and one Digital Elevation Model (DEM) were used to construct land use classification for both SMEX04 study regions: Arizona, USA and Sonora, Mexico.数据用户须知：本数据集的文档仅由首席研究员（Principal Investigator）提供，未由美国国家冰雪数据中心（NSIDC）进行进一步完善、严格审核或编辑。因此，本数据集的相关支持服务可能较为有限。 本数据集包含为2004年土壤湿度实验（SMEX04）中水文变量建模与尺度转换所需的土地利用分类数据。研究团队利用6景陆地卫星5号专题制图仪（TM）影像与1套数字高程模型（DEM），为SMEX04的两个研究区域——美国亚利桑那州与墨西哥索诺拉州——构建了土地利用分类数据。
