problems using arcpy.UpdateCursor in Mosaic dataset

GualbertoHernández_Juárez — Sun, 25 Nov 2012 12:35:04 GMT

Hi,

Following on from a netCDF file generated several raster and then built a mosaic dataset, finally need to add time for each raster that form the mosaic.

Create the following code but I added the last time all previous raster.
I need each raster has its respective time. (the problem is in the last part of the code)

Can you help?
thank you very much
