Hello,
i am using Arc GIS 10 and i have the following problem:
When i start the tool "Reclassify" with a Raster DataSet i get the error massage :"ERROR 010423[...]does not have valid statistics as required by the operation."
So i tried to fix it with "calculat Statistics" for the Raster Dataset. But even after doing this, i got the same Error
I use Reclassify inside a modell and i know that it worked before i installed Service Pack 1 and 2 so i tried to remove the two servicepacks and now the Reclassify works.
I think its a bug in SP 1 because i first removed SP2 and tested , with no succes und than i removed SP1 and the failure was gone.
If the zone input is a feature dataset with relatively small features, keep in mind that the resolution of the information needs to be appropriate relative to the resolution of the value raster. If the areas of single features are similar to or smaller than the area of single cells in the value raster, in the feature-to-raster conversion some of these zones may not be represented.
To demonstrate this, try converting the feature dataset to a raster with the appropriate feature-to-raster conversion tool and specify the resolution to be that of the Value raster. The result from this conversion will give an indication about what the default output of the zonal operation will be.
If you have fewer results in the output than you may have expected, you need to determine an appropriate raster resolution that will represent the detail of your feature input, and use this resolution as the Cell Size of the Raster Analysis Settings of the Environment.
