extended Thiessen polygon

RogierBusscher — Sun, 09 Sep 2018 18:33:20 GMT

Hello,

I am trying to fill a rectangle with some points and create thiessen polygons based on these points.

I tried using the 'create thiessen polygon (analysis)' tool, and it works fairly well, just not precisely what I want.

The result that is generated is the pink area below, with the minumum x and y and maximum x coordinates working as the boundaries. (Somehow this doesn't happen with the maximum y).

However, I would like to fill the entire blue space.

Does anyone have a suggestion how this can be done?

Thanks a lot.

Are you using the min x min y max x max y of the pink space or the blue space? Use the latter. If that doesn't work, experiment with adjusting them until you get what you want.

This is in fact the solution. When I turned the XY-extent (shapefile properties > Feature extent) settings to that of the blue rectangle the polygon turned out as I wanted to.

Thanks a lot!
