I have a polygon feature class
Base_FC, where each poly has a unique alphanumeric ID. My second polygon feature class
Type_FC has the details for the various polygons which would fall inside
Base_FC when intersected. These polys have unique alphanumeric IDs as well.
For display purposes, I would like to assign each
Type_FC poly that falls within a
Base_FC poly a number, along with its neighbouring polys. For example:
Base_FCpolygon B1 contains three
Type_FCpolys T5, T8 and T11.
Base_FCpolygon B2 contains four
Type_FCpolys T20, T21, T25 and T30.
The numbers should ideally be assigned spatially from left to right, so if B1 has the polys going from left to right as T8, T5 and T11, they would be labelled 1, 2 and 3 respectively. I realise that there are a number of ways to do this - the method I was thinking of was to create a model which iterates through each
Base_FC feature, selects by location all the
Type_FC features it contains, then use the Python field calculator to number them - but I'd like to know of other methods, or if there is a tool out there which can do this.
I'm also not sure how to handle the issue of numbering them so that visually it looks good. Maybe using the coordinates of the centroids to ensure numbering goes from left to right?
