NumPyArrayToRaster (in_array, {lower_left_corner}, {x_cell_size}, {y_cell_size}, {value_to_nodata}) 参数 说明 数据类型 in_array 要转换为栅格的 NumPy 数组。需要二维或三维 NumPy 数组。 NumPyArray lower_left_corner 定义地图单位中输出栅格左下角的 Point 对象。 默认情况下,左下角的坐标...
NumPy 数组中的整型字段不支持空值。如果使用FeatureClassToNumPyArray或TableToNumPyArray转换的数据包含空值,系统会完全跳过包含空值的行,或使用替代值将其掩膜。 跳过所有包含空值的记录。 arr=arcpy.da.FeatureClassToNumPyArray(fc,fields,skip_nulls=True) ...
I would like to use arcpy.NumPyArrayToRaster to import a numpy array and use in arcGIS10 as a raster. This function works fine except I did not enter the lower left

Numpy Array是NumPy库中的一个重要数据结构,它是一个多维数组对象,用于存储和处理大规模的数值数据。Numpy Array可以根据条件存储坐标,即根据特定条件筛选出符合条件的元素的坐标。 ...
我有两个raster文件,我已经将它们转换为NumPy数组(arcpy.RasterToNumpyArray),以便使用raster单元格中的值处理raster。其中一个raster有两个值True和False。另一个raster在0到1000之间的范围内有不同的值。两个rasters都有完全相同的范围,因此,除了值之外,两个NumPy数 浏览2提问于2014-04-10得票数 2 回答已采纳...
