[pgrouting-users] pgr_alphaShape, pgr_pointsAsPolygon, pgr_drivingDistance

[dave.potts at pinan.co.uk]

Perhaps a silly question

Are pgr_alphaShape and  pgr_pointsAsPolygon desgined to work on the return
dataset from  pgr_drivingDistance to create a polygon representation of
the results ?

It just that I saw the comment 'This function should not be used directly'
on  pgr_alphaShape and got some what confused.

regards

Dave.
