[MetaCRS] CS-MAP: NSRS 2007 & NSRS 2011

[Norm Olsen]

Hello All . . .
 
I have submitted all code required for the subject features to the 
svn.osgeo.org/metacrs/csmap repository.  What I submitted was tested
in both Windows and Linux.  On Windows, I use Visual C++ Studio,
version 8 on Windows 7.  On Linux, I'm using gcc version 4.4.7 on
platform running CentOS 6.3.
 
Issues that I am aware of:
 
1> While my sandbox copy compiled and tested fine on Linux, after 
submission to the trunk it did not.  The problem appears to be related 
to changes to a module named csIoUtil.hpp which was only recently 
submitted (16 April 2014).  The Windows version of the current trunk 
(csIoUtil.hpp included) does compile without a problem.  I suspect the 
submitter of this module may need to verify his/her work functions 
properly under Linux.  I consider it unlikely that the two revisions 
being submitted are interfering with each other.
 
2> The latest version of Visual C++ that I have access to is 9.0 (i.e. 
2008).  Therefore, I am unable to test (and therefore did not modify) 
Visual C++ project files for versions 10.0 and 11.0 with the new code 
modules required by this upgrade.  Clearly, some new source code files 
will need to be added to these project files.  The "make" files (both 
.mak and .nmk) have been updated and appear to produce the necessary 
results.
 
3> A full implementation of the NSRS 2007 and NSRS 2011 feature requires 
data files which total out at about 300 megabytes.  That's because there 
are:
    a> a latitude, longitude, and a vertical file for each geographic area,
    b> two large geographic areas (US48 & Alaska) and a relatively tiny 
one (Puerto Rico), and
    c> there exists a complete set for converting from HARN to NSRS 
2007, and
    d> another complete set for converting from NSRS 2007 to NSRS 2011, and
    e> the grids are very dense; the cell size is one minute by one 
minute (even for Alaska!!!).
These data files are not required unless a user requests a conversion to 
or from one of the NSRS datums.  Thus, a distribution does not 
absolutely have to include all 300 megabytes.  A decision on how to 
handle this will need to be made.  I have suggested a de-densification 
of these data files, but received no responses.
 
4> The NameMapper has been updated with the latest information on the 
EPSG and ESRI versions of all NSRS related CRS definitions.  I have no 
information on Oracle or anyone else.
 
Enjoy.
