Help Model Builder for a research project

Question

Hello, I am currently working on a saltmarshes mapping project and each habitat interface is a unique polyline. I want to generate polygons with the information contained in the polylines. On the other hand, the information contained in the polylines is all different and I cannot just check the "keep attributes" during the conversion. The way I thought to find the right information to keep is to select all the lines that touch the polygon and see which habitat comes up most often. This is the one that will be the information to keep.

Because I have like 20 000 lines (and get like 5000 polygons), that needs to be done with a Model Builder.

In the attached files, I made a sketch to explain my idea to you and a model I made so far (i'm a beginner with model builder and Python).

Thank you so much !

and changing the field length from 255?

I tried but it still a lot of manual work because I have a lot of unique variable to assign a number to. And it needs to convert the numbers to the attribute after the trick with Mode. But thanks, I'll try to find a way to make it work!

Hi Serge,  I guess you could assign a number to your attribute in a new field then use Mode, but you can just change the maximum field length to whatever you want and that would solve the issue.  Ensure it's a feature class in a file geodatabase and not a shapefile.
