如何对非常大的土地覆盖数据集进行分类?
考虑阿拉斯加的NLCD2001土地覆盖数据集(下载链接)。我需要对该数据集进行重新分类,以便仅保留值41、42和43的像素;所有其他像素值应变为NoData(如果需要,则为0)。 这似乎是一项简单的任务,只需要调用一次“重新分类”工具即可。不幸的是,每次调用都会导致模糊而无益的错误消息: Executing: Reclassify "D:\ak_nlcd_2001_land_cover_3-13-08_se5.img" Value "0 40 0;41 41;42 42;43 43;44 255 0;NODATA 0" "D:\alaska_reclassified.tif" DATA Start Time: Thu Jan 03 09:23:13 2013 ERROR 999998: Unexpected Error. Failed to execute (Reclassify). Failed at Thu Jan 03 09:23:13 2013 (Elapsed Time: 0.00 seconds) 如何对该栅格数据集进行重新分类?我正在使用启用了Spatial Analyst扩展的ArcCatalog 10.0,Build 4000。
