Field Maps - populating field based on another layer's field

YS2388 — Mon, 31 Jul 2023 17:33:54 GMT

Hello,

I am creating a field map. There is a point and a polygon layer. The point layer is where the features will be collected (created). The points will be created inside the features of the polygon layer. I am wondering if it is possible to have a field in the point layer be populated by a value from the polygon layer based on which polygon the point was placed in?

Basically, the polygons have a "PlotNumber" field, can this value be transferred to the "PlotNumber" field in the point layer, based on which polygon the point was placed in?

Thank you.

Pretty sure there's a query you can create when calculating the field. Not entirely sure what the expression would be, but can tell you that it will most likely be a calculate field after all of your points have been created. You could also do it by section where you intersect/select all of the points in a plot then calculate the field to equal whatever number plot you are located in. I know that's a bit lengthier than automated field calculation but that's all I can think of off the top of my head.

Take a look at this blog for an example of how to automatically populate an attribute from another layer.

Thank you! The "intersects" function did the trick.
