Multi-resolution Ridge Top Flatness (MrRTF)

MrRTF is a topographic index designed to identify high flat areas at a range of scales. It complements the MrVBF index that is designed to identify areas of deposited material in flat valley bottoms. Unlike MrVBF, the MrRTF index does not have a clear link to landform processes but it has been found to be a useful adjunct to MrVBF in landform classification. Zero values indicate areas that are steep or low, with values 1 and larger indicating progressively larger areas of high flat land. This collection includes MrRTF data at 1 arc-second and 3 arc-second resolutions. The 3 arc-second resolution product was generated from the 1 arc-second MrRTF product and masked by the 3” water and ocean mask datasets.MrRTF是一种可在多尺度范围内识别高平坦区域的地形指数（topographic index）。该指数可作为MrVBF（MrVBF）指数的有效补充：MrVBF指数的设计目标为识别平坦河谷底部的沉积区域。与MrVBF不同，MrRTF指数与地貌过程并无明确关联，但现有研究表明，其在地貌分类中可作为MrVBF的实用辅助工具。其零值代表陡峭或低海拔区域，数值为1及以上则表示高平坦区域的面积随数值增大而逐步扩大。本数据集包含1角秒与3角秒分辨率的MrRTF数据，其中3角秒分辨率的产品由1角秒分辨率的MrRTF数据生成，并通过3角秒水体与海洋掩膜数据集完成掩膜处理。
