New Spatial Analyst Supplemental tools, v1.3

With this update to the Spatial Analyst Supplemental Toolbox, we have added a new Tabulate Area 2 tool, a new Zonal Statistics as Table 2 tool, and added a new parameter to the Maximum Upstream Elevation tool. Read on for more details on the improvements these tools offer.

New tools

  • Tabulate Area 2
    The new Tabulate Area 2 tool, as does the original Tabulate Area geoprocessing tool, calculates cross-tabulated areas between two datasets.  This new version offers an improvement over the original by handling overlapping polygons in feature zone input.
  • Zonal Statistics as Table 2
    The Zonal Statistics as Table 2 tool calculates statistics using the values of a raster within zones and reports the results to a table.  This new version offers an improvement over the original Zonal Statistics as Table  geoprocessing tool by fully handling overlapping polygons in feature zone input.
    (Note: The Zonal Statistics as Table For Overlapping Polygons tool that was made available in v1.2 of the Spatial Analyst Supplemental Tools has been deprecated with this update.)

Updated tools

  • Maximum Upstream Elevation
    The Maximum Upstream Elevation tool has a new parameter that lets you decide on the method by which the longest upstream path is to be determined.  By default, the maximum elevation from all the cells that define the upstream watershed will be returned.  Optionally, you can elect to have the result be the maximum upstream elevation just for the cells that define the longest upstream path.

Downloading and installing

The Spatial Analyst Supplemental Toolbox version v1.3 is available for download here:

http://esriurl.com/SpatialAnalystSupplementalTools

Click the Open button, then select Download. Save the zip file to your machine, then extract the contents. In ArcMap, open the Catalog view and navigate to the location you extracted the files to. You should see a a folder called SpatialAnalystSupplementalTools there, which will contain a Python toolbox with the Script tools.

Note that the samples are geared for ArcGIS version 10.1 SP1 and beyond.

    Will these be released for version 10.2?

      I would also like to know if these tools will be available for 10.2.

        Hello, todd93 and mringel.

        These tools will indeed work with ArcGIS 10.2. While the Note in the “Downloading and Installing” section above does state that the samples will work from ArcGIS 10.1 SP1 and higher, in the actual download page I had the Access and Use Constraints section updated to be more specific about this. It now says the following:

        Requirements:
        ArcGIS 10.1 Service Pack 1 or later and Spatial Analyst Extension

        I hope this clears things up for you.

        Cheers,
        Juan

    Hi,
    First, thanks for this very usefull toolbox. I’m using Zonal Statistics 2 for attributing raster values to overlapping features. It works greatly, however I do encounter a problem: not all of my features are attributed values. About 10% are left out. These seem to be mostly the smallest shapefile features in my data set. When identifying those left out and re-running the Zonal Statistics 2 tool only on those, 50% were attributed then a value and the rest were again left out.
    Any ideas about what is going on there?
    Thank you

      Forget that, is was a problem of raster size…

        Hello, Bastre.
        I’m glad you were able to resolve the issue. We were just about to prepare a response for you when your reply came in.

        The Usage notes for Zonal Statistics as Table does try to cover most of the issues typically encountered when running the tool, so hopefully it was helpful to you.

        Cheers,
        Juan
