Is it possible to use Data Pipelines to generate a circular buffer polygon around a point?

DBRCoordinator

I would like to create a pipeline that automatically checks for new points created in one point layer daily and creates a circular buffer at a defined distance around each of those points in a new layer. I have tried to the "create geometry" tool, which does have polygon listed as an option under "geometry type" but am lost on what type of "geometry format" to use and what should be contained in the "geometry field" of the point layer. All points will be buffered to the same distance so that field can be a default value in the point field when the point is created. 

 

I've done a little research on community and over a year and a half ago there was mention of adding the ability to buffer points to pipeline but I can not find any newer references than that.

Hi @DBRCoordinator ,

Thank you for reaching out with your question and for providing screenshots!

In the screenshot of the Calculate field tool, I see that you used an expression as follows: Buffer($record,200,'meters')

I believe this is what is causing the issue. The expression should be specified like so:

Buffer($record.<geometry field name>,200,'meters')

The difference is changing $record to $record.<geometry field name> . For example, if the feature layer has a geometry field named "shape", specify an expression as follows:

Buffer($record.shape,200,'meters')

Unlike feature layers or feature classes, datasets in Data Pipelines can have multiple geometry fields. With that, we require the geometry field is explicitly specified, rather than operating on the entire record and assuming the geometry.

Please let me know whether this change in expression helps, or if you have any further questions. 

Thanks again,
