Tessellate by Mask instead of only Extent

EricEagle

I rely heavily on tessellation to aggregate and summarize extremely dense point content. Currently the only limiting environmental variable the GenerateTessellation_management() method uses is Extent. This is inefficient as I demonstrate in the simplified graphic above. In this case, I would spend loads of time building cells over an extent, the majority of which has no data, and that will be discarded later anyway.

I would like for the Generate Tessellation tool to support not only Extent, but Mask (vector polygon) to build cells.

Yes, please! I’m working with global data and tessellations only by a mask (polygon) is a Must!

For example, I’m trying to develop a 10,000 sq meter tessellation from the shoreline out 1 mile for all US States (Conus, AK, HI, Puerto Rico and Guam). The extent results in a tessellation where the size is 35 billion with a B features. When in reality I only need less and 1% the extent with this size grid.

Help?! My computer is sitting at 0% complete in the progress bar now for over 1 hour.

@EricEagle , any luck since your post a couple years ago?

Hi Doug,

Unfortunately, no. I haven't heard anything from Esri on it. Probably what I should do is send this up via my Esri customer rep and get it put in as an enhancement request. I seem to have better luck that way. It is unclear how Esri harvests and approves ideas from these boards. Sometimes I'll see an idea with 2 votes "under review" and sometimes even implemented, while other ideas with dozens of votes go completely unaddressed.
