#10983: box-box distance doesn't seem to work with spherical coordinate systems
-----------------------+------------------------------
 Reporter:  mdrinto@…  |       Type:  Bugs

Component:  None       |    Version:  Boost 1.57.0
 Severity:  Problem    |   Keywords:
-----------------------+------------------------------
 The "geometry distance matrix" indicates that all geometry-to-geometry
 distances have been implemented in 1.57.  But the box-to-box distance
 doesn't seem to work with spherical geometries, at least with gcc 4.4.7.

 One of the errors seems to be a "not yet implemented" error, so perhaps it
 hasn't been done yet.  It does have some tricky business that a cartesian
 box wouldn't have, but it's a straightforward exercise in trying different
 cases.

 I'm certainly delighted with boost::geometry's functionality as is, but it
 would be great if this worked.  And many apologies if the mistake is mine.

 See example below for problem.

 {{{
 #include <boost/geometry/geometry.hpp>

 typedef
 boost::geometry::model::point<double,2,boost::geometry::cs::cartesian>
 cartesian_point;
 typedef
 boost::geometry::model::point<double,2,boost::geometry::cs::spherical_equatorial<boost::geometry::degree>
 > spherical_point;

 int main()
 {

   // Works...
   boost::geometry::model::box<cartesian_point> c_box1, c_box2;
   boost::geometry::distance(c_box1,c_box2);

   // Doesn't work!
   boost::geometry::model::box<spherical_point> s_box1, s_box2;
   boost::geometry::distance(s_box1,s_box2);

   return 0;
 }
