Thank you all for your help! Graeme and Nicholas were on the same track I
think, and Micha - I knew this would likely be very simple (and already a
tool) in PostGIS, but it's not my go-to approach, so I'm actually going to
try this out bc it will solve my problem AND give me a bit more experience
This can be achieved using the
PostGIS function ST_MinimumBoundingCircle(). If you can import
your subplots point layer into a PostGIS database, then
(assuming the points have an attribute "subplot_id", and
geometry column "the_geom") you could do
I don’t have enough experience of coding steps in QGIS yet, but could you do
the following?
For each set of points sharing a plot ID attribute value:
Identify the distances between all points.
Take the furthest apart pair (or one set of if more pairs are
equal), which
Hi,
This could work but there may be a more efficient way. Here are my ideas.
1) Split vector layer using the ID for each plot/cluster.2) Create a polygone
from the file extent. (use the processing toolbox), merge all the polygone into
1 file.3) Find the centroid of this shape and the maximum
