Invitation to participate in an Esri software Usability Study at the User Conference

The Esri development team would like to invite you to participate in a moderated and recorded usability study of a new application for GIS professionals currently under development.

Who we’re looking for…

  • Existing ArcGIS for Desktop users
  • ArcGIS Online and App users interested in professional GIS software
  • Users of Esri Solutions (Local Government, Water Utilities, Land Records, 3D cities and campuses)
  • Users with varying degrees of experience who author maps,  analyze \ edit data, and manage GIS content

In total, we’re looking for 30 committed testers.

How it works…
Our sole intent and goal for this study is to assess the usability of our next generation professional desktop software; we want you to test our software, we’re not testing your computer, nor ArcGIS skills.

To consider you as a usability tester, we require that you are registered and approved by your employer to attend Esri User Conference and complete a pre-screening questionnaire—details below. Your time in the test lab is about 40 minutes.

Your test session will be recorded and observed by one or more members of the development team.

We thank you in advance for your time and look forward to meeting you in San Diego.

Are you sure Intersect is the right tool for the job?

Are you sure Intersect is the right tool for the job?

UPDATE

ArcGIS Pro 1.0 introduced a PairwiseIntersect tool which emulates the pairwise tool discussed in this blog post.
ArcGIS Pro 1.1 has an additional pairwise tool, Pairwise Dissolve.
By default, starting in ArcGIS Pro 1.1, both the PairwiseIntersect and PairwiseDissolve tools run in parallel mode. This will allow these tools to distribute the work to all (or a portion of) the logical cores on the machine. The performance benefit of parallel processing varies from tool to tool and depends on the input data being processed.

Please see the following for more info: PairwiseIntersect and PairwiseDissolve

(Note: There are no system Pairwise tools provided in 10.x. Continue to use the provided methodology and scripts included with this post.)

=========================================================

I often talk with people using ArcGIS Geoprocessing who find themselves surprised about the amount of time the Intersect tool takes to run, or confused about the output results.  Much of the time this confusion comes from a misperception about what tool to use for the analysis, or from a lack of understanding of what the Intersect tool does.

Here’s an example… A user contacted me about the Intersect tool because the tool would run for hours and then fail. They perceived their data as small and really thought Intersect would only take a few minutes.

My first question, and one you should ask too is, “What do you really want for a result?”

The answer in this, and many cases was “I want to know how much of each feature in input 1 is in each feature in input 2.”

Cool!  That means Intersect is not the right tool to use! Continue reading
