How to set a zone field as model parameter in zonal statistics

JanOtto — Thu, 05 Mar 2020 10:06:18 GMT

Hi,

I have produced a little tool in modelbuilder, which includes a ZONAL_STATISTICS step.

In this dialogue I use a shape file as feature zone data.

I can set this a variable and make it a model parameter for the tools input dialogue.

But the zonal_stats also requires the selection of a zone field, i.e. the identifyier to distinguish between objects.

For more automatisation I would have this zone field also included in the tools input dialogue.

Is there a way to identify a zone field as model parameter/variable?

Thank you for your help,

Jan

You can specify parameters in a model's tools

Model parameters—ArcGIS Pro | Documentation

right-click on the tool and you can specify the parameter you want

Hi Dan,

thanks for the hint.

I managed to solve my issue to a great part.

One thing remains:

The Zone field as model parameter only displays one field (a string type) and not the others.

I would like to refer to a field containing numbers.

Any Ideas?

Best regards,

Jan

in a script you can set the parameter as "derived", so if the parameter is a "field", the values that are available would be "derived" from the input dataset. I dont know if it applies to modelbuilder
