Points along a polyline with equal total line lengths between points

AttA

Hi everyone,

I'm working with a stream represented as a braided polyline. My goal is to place points along the stream such that the total length of the polyline segments between consecutive points is constant.

The stream's braided nature means the polyline isn't always a single straight line, and the segments can have varying orientations and curvatures (see screenshot).

I'm looking for advice or methods to achieve this. Any suggestions or insights would be greatly appreciated!

Thanks in advance!

buffer the braided stream by a distance to collapse the braided streams (use the dissolve all features option )

Buffer (Analysis)—ArcGIS Pro | Documentation

You should now have a buffer without any interior holes (hopefully)

Ifffff you have the Topographic Production extention, then you could use

Polygon To Centerline (Topographic Production)—ArcGIS Pro | Documentation

but assuming you don't, then you could reverse the buffer using a negative distance which "might" yield a single skinny polygon.

Other options would be conversion to raster after a negative buffer, then thinning the raster and conversion to polyline if you want a line rather than a polygon.

Thin (Spatial Analyst)—ArcGIS Pro | Documentation

There are many other options, but you will not a a one-shot tool that will do what you want for all stream braiding patterns
