Subject [sis] branch geoapi-4.0 updated (aacd07f -> 919c2f2)
Date Sat, 03 Aug 2019 08:19:36 GMT
This is an automated email from the ASF dual-hosted git repository.

desruisseaux pushed a change to branch geoapi-4.0
in repository https://gitbox.apache.org/repos/asf/sis.git.


    from aacd07f  Create a ClenshawSummation helper class for applying the Clenshaw summation
technic (recommended by Karney) on Karney equation 25. This technic has been applied in other
places in Apache SIS since it happen often in map projections. Before this class, we used
an OpenOffice spreadsheet for performing this summation. But Karney equation 25 is more difficult
because of its dependency to another term, the third flattening factor. Using an OpenOffice
spreadsheet was no longer [...]
     new 59d8460  Apply Clenshaw summation on Karney equation 25.
     new 98080c7  Now that the development of geodesic distance is completed, set STORE_LOCAL_VARIABLES
debug flag to false.
     new 31042ac  Adjustment in the way iteration tolerance is determined.
     new 919c2f2  Use the same latitude difference threshold for geodesic and rhumb line distances.

The 4 revisions listed above as "new" are entirely new to this
