Now need to write a trigger such that the
These points were created from a GPX file along a road journey so they
crudely map to a line string
Map matching is the term often used to describe the process of assigning
noisy Gpx points to underlying road network.
I was thinking compute the KNN distance for each point and remove
If I had a table of points which are irregularly distributed and wanted to
evenly distribute them what would be the best strategy and query?

Hello,
You could build the linestring from points (makeLine(geom order by time))
then , with linear referencing (st_lineInterpolatePoint,
st_linelocatePoint), you can divide your linestring by the distance you
want, creating new points.
Then, if you need to keep time information, you could
