[MetaCRS] CSMAP: Deploy custom coordinate systems to server using CS-MAP

[CsMap Contractor]

Hello Clement . . .

 

RFC -6 was indeed implemented, just not marked as have been so.  The only
documentation I am aware of, however, is the RFC-6 document itself.
Presumably, if your work in Civil 3D produced two .csd files in a directory
somewhere, you should be able to copy those two files in a similarly
situated directory on your server and use the CS_usrdir() API to inform
CS-MAP where it is.  Note: If your server is not a little endian machine
(i.e. is not the same as the machine your Civil 3D is running on), you might
encounter a byte swap problem.

 

Actually, it turns out that the API is CS_usrdr ().  It is defined in
CS_general.c at line 151:

 

/**********************************************************************

**     int result = CS_usrdr (usr_dir);

**

**     char *usr_dir;                           the directory where to store
all custom definitions in.

**                                                     Note, that this
directory isn't required to contain

**                                                     any CSD files (yet).

**                                                     Must be less than
(MAXPATH - 1) characters.

**                                                     If NULL or empty, the
user dictionary path will be unset.

**                                                     That is, all user
defined definitions will be written

**                                                     into the CSD files
found in the directory specified

**                                                     in [cs_dir].

**

**     result                                   0 if successfull, -1
otherwise

**

**     Note, that this method can only be called, if cs_Protect is >= 0.
That is,

**     the protection scheme for 'system' definitions must be somehow
enabled.

**********************************************************************/

 

If you have built CS_MAP from source code, you also have the option of
adding your custom definition to the coordsys.asc and category.asc files in
the Dictionary folder and simply recompile the dictionaries (CS_Comp.exe or
equivalent).   You would then need to make sure your custom definition does
not get erased by an update somewhere along the line.

 

Hope this helps.

Subject: [MetaCRS] CSMAP: Deploy custom coordinate systems to server using
CS-MAP

 

Hi,

 

My company uses CS-Map for coordinate transformations and I need to add
custom coordinate system definitions to the standard coordinate system
library. I have successfully created  new entries using AutoDesk Civil 3D on
my machine, and have located the corresponding “Category.csd” and
“Coordsys.csd” files autocad generated for me.

 

I am stuck when trying to deploy these to our server running cs-map: I do
not want to overwrite the existing “Category.csd” and “Coordsys.csd” files
there for obvious reasons.

 

Looking online for information on how to achieve this, I came across this
RFC:

https://trac.osgeo.org/csmap/wiki/CsMapRfc6

 

Which is quite old, and marked as “adopted” but not implemented
 Is anyone
able to tell me tell me how to proceed to get my server side csmap
deployment to recognise my custom entries?

 

Thanks!
