Global sand, silt, and clay fractions of surface soils and derived drying time (min)

Data are in TIFF/GeoTIFF Format and can be opened in standard image processing (for remote sensing data) or GIS (e.g., ArcGIS, QGIS) software. Because the images are raw floating point data and not image data, an image viewer (suitable for photos, for example) will not display the data correctly and may fail to open the image altogether. The .tfw file is the "world" file that must accompany the .tif image (in the same directory) when opening in order for the image to be properly geographically registered.

本数据集采用TIFF/GeoTIFF格式，可通过适用于遥感数据的标准图像处理软件或地理信息系统（GIS，如ArcGIS、QGIS）打开。由于该数据为原始浮点型数据而非常规图像文件，普通图片查看器（如适配普通照片的查看工具）无法正确显示该数据，甚至可能完全无法打开文件。.tfw文件为“世界文件”，在打开.tif图像时需将其与.tif文件置于同一目录下，方可实现图像的正确地理配准。
