Classes Intersectool and Intersector, a pure Python version of Karney's C++ class Intersect to find the intersections of two geodesic lines or line segments.
Intersectool and Intersector methods All,
Closest, Next and Segment
produce
XDict
instances with 4 or more items. Adjacent methods All5,
Closest5, Next5 and Segment return
or yield Intersectool5Tuple or Intersector5Tuples with the lat-, longitude azimuth of
each intersection as an extended or Position-like GDict.
Class Intersectool is a wrapper to invoke Karney's IntersectTool utility like class Intersector, but intended for testing purposes only.
Set env variable PYGEODESY_INTERSECTTOOL to the (fully
qualified) path of the IntersectTool executable.
For more details, see the C++ GeographicLib documentation, Charles F.F. Karney's paper Geodesics intersections and S. Baselga Moreno & J.C. Martinez-Llario's Intersection and point-to-line solutions for geodesics on the ellipsoid.
Version: 24.07.09

XDict 4+Item result from Intersectool and Intersector methods All,
Closest, Next and Segment
with the intersection offsets sA, sB and
sX0 in meter and the coincidence
indicator c, an int, +1 for parallel, -1
for anti-parallel or 0 otherwise.

Intersectool Wrapper to invoke Karney's utility IntersectTool similar to class Intersector. |
|
|
Intersector Finder of intersections between two goedesic lines, each an instance of GeodesicLineExact, wrapped GeodesicLine or GeodesicLineSolve. |
|
|
Intersectool5Tuple 5-Tuple (A, B, sAB, aAB, c) with A and
B the Position of the intersection on
each geodesic line, the distance sAB between
A and B in meter, the
angular distance aAB in degrees and
coincidence indicator c (int), see XDict.
|
|
|
Intersector5Tuple 5-Tuple (A, B, sAB, aAB, c) with A and
B the Position of the intersection on
each geodesic line, the distance sAB between
A and B in meter, angular
distance aAB in degrees and coincidence
indicator c (int), see XDict.
|
|
|
Middle5Tuple 5-Tuple (A, B, sMM, aMM, c) with A and
B the line segments including the mid-point
location in latM, lonM, distance
s1M in meter and angular distance
a1M in degrees, the distance between both
mid-points sMM in meter and angular
distance aMM in degrees and coincidence
indicator c (int).
