Topo To Raster Results (10 vs 10.1)

[MatthewGrantham]

Hello,

I've been able to successfully use Topo To Raster to contour rainfall data with ArcGIS 10 for quite some time now. Since upgrading to 10.1 and using the same exact settings, the results of the interpolation are much different and not as accurate. The interpolation is much more smoothed and does not accurately depict maximums and minimums (images are attached). Is anyone else having this problem?

Note: There are approximately 10,000 data points in the interpolation, and only some of them are shown on this map.

Note: Using IDW I am able to achieve the same results in both 10 and 10.1.

TopoToRaster was updated in 10.1 to use the latest version of anudem, see

Thanks for the reply Steve.

Topo To Raster is now completely useless for me unless there is something I can change in the settings to get more accurate results. This tool worked great for my application before this so called "upgrade" and provided the most visually pleasing representation of my data.

It looks like I am at a dead end here and will have to use another interpolation tool. Any suggestions?

can you email me (slynch@esri.com) your data and the parameters (use the Output parameter File) that you are using and I'll have a look.
