Output Extent

Question

Hello All,

Is there a way to set the final extent of a map based on one of your outputs in a model?

If so how

Thanks

Eric

A geoprocessing model does just that: it geo-processes data.
When you talk about "map extents" and "zooming", you are dealing with graphic expressions of data: maps.

It is not entirely clear which you are wanting to obtain as a result: a data set or a map. Your subsquent expalnations raise doubts about my original understanding of your question.

My suggestions pertain to creating a map with map extents matching the extents of the data set output from the geoprocessing  model / script / service. For that, you need to go through the python arcpy.mapping module, and to have set up (at least a rudementary) mxd, so as to compose and output the map.

If, on the other hand, you are using the term " final extent of a map" to mean "extent of a data set", then most of what I wrote is entirely beside the point.

Thanks for the quick reply but you just threw a fastball right by me. 😄

I may need a little more explanation

The model I am making is going to be used as a Geoprocessing service, if this matters.

I have attached an image of an example of a model with the basics of what I am trying to do.

I am hoping to eventually build a widget for a viewer to run this process and would like the output results to be zoomed to.
However I am not entirely sure if this is something that I should do in the model or if this is a parameter for the widget.

So your opinion or any help you could provide would be great.

Thanks

Eric
