As one can see from the picture the task has a solution for shapes equal to their own convex hull. If it is not the case, the position of point and 'un-convexness' of polygon might create artefacts. Output can be slightly improved by using minimum spanning tree of the points, but it's cheating and too much for today. import arcpy, traceback, os, sys from ...

An easy way to show overlapping features is by using the Intersect tool. Use your buffer dataset as the input and run the tool. It will create an output that will only show the overlapping areas. Unfortunately I am unsure how you could show this through symbology alone without any extra processing.

You would need to symbolize all the buffers in a unique manner, and the symbology you choose would need to be some sort of pattern fill; lines, pictures, markers, etc. - something with transparency. The patterns would need to be set uniquely enough, via color and/or shape, such that when they overlap they are distinguishable. You can see a simple example of ...

If you are using ArcGIS 10.x or Pro When you are creating your buffer there should be a "dissolve type" option. For this you will select ALL. This should dissolve the buffers as they are created to make one large overall buffer. Then with the symbology you can make it so it is just represented by an outline by making the fill color set to no color. EDIT: ...

You could use Zonal Statistics as Table to generate a table with a Unique ID field that can be used to join to the polygon buffer attribute table. The tool takes 1) a dataset that defines the zone (your buffer polygons), 2) a zone field (some unique ID field in the buffer polygons), 3) a raster that contains the values on which to calculate a statistic ...

I would recommend scripting this as you'll save a hell of a lot of time...but you could do this via adding fields to the attribute field and run an analysis to produce the proportional distance value from the point to the basin edge. Are you looking to buffer distance from the point to the basin edge or from the basin edge to the point? With this data you ...

You can do this by using a field in your layer's attribute table as the source for the buffer distance, rather than specifying the distance manually. This works in either the Buffer Wizard or the Buffer geoprocessing tool. You would first need to create a field in your feature class, then populate it with the buffer distances you'd like to use for each ...

Now possible with the Multi Ring Buffer: https://plugins.qgis.org/plugins/Multi_Ring_Buffer/ In version 0.1 it only works on the layer that is selected in the TOC when you launch the tool but feature requests can be posted to the issue tracker: https://github.com/HeikkiVesanto/QGIS_Multi_Ring_Buffer/issues
