Hi, Listers!
Here is one which we really need your help on:
Question:
=> How do I find the angle of a line at a given point without having to
write a lengthy MapBasic program? (MapX would be OK since we're developing a
C++ application)
Problem:
=> Putting a "One Way" Symbol on each of the street segments that
represent One Way streets.
=> Symbol should be placed only once for each street, in or near the
centroid, and in an appropriate angle. Streets are MI lines with 0 to many
vertices, starting and ending in a crossroads, with no crossing in between.
Prerequisites:
=> We would prefer a solution using SpatialWare / Oracle / MapX (as
opposed to MI Pro / MapBasic).
=> Coordinates of beginning and end of lines are available in
SpatialWare.
=> We're dealing with millions of streets, 10% of which are One Way...
Any hints would be greatly appreciated! - Will post a summary.
