I have polygon made up of many different points,it some cases its rather
to accurate for my requirments,i.e. its generating a lot points to
describe a minor change.
I had throught that by saying something like
)).geom) as the_geom from
journey_table jt, coast_polygon pa where jt.generation=1
Would give me minmum list of data points for describing a polygon. What
it does give me long gap, 3 coordinates, another long grap then another 3
Where these 3 coordinates are they close together. What I had hope to get
list the lowest number points that would be useful to describe a polygon.
Q. Is there a better way of doing this.
