[mapguide-users] OGR FDO Provider

[Andy Morsell]

Hi Traian,
This looks like it could be great.  Can you provide some more details on the
connection string requirements?  For instance, for Oracle Spatial:
 
CONNECTION "OCI:user/pwd at service"

Does your provider require the entire connection string entered in the
DataSource field?  Or is CONNECTED already handled?  And, for username and
password, is that entered in the connection string or through the Studio GUI
fields?

Thanks very much.

Hi all,
 
I started work on an FDO provider for OGR. I have posted a preview binary
under:
 
https://mapguide.osgeo.org/files/documents/12/163/OGRProvider_bin_win32.zip
 
This is a Win32 binary, compiled with ODBC and Oracle Spatial (OCI.dll
required) support.
The source code, so that you can add in support for other data sources or
compile on Linux, is here:
 
https://mapguide.osgeo.org/files/documents/12/164/OGRProvider_src.zip
 
So far I have (successfully) tested the following data sources:
 
* SHP
* MapInfo files
* Oracle Spatial
* ESRI personal geodatabase (.mdb, via the ODBC driver)
 
The functionality gaps are:
 
* You can only read (no insert/update/delete).
* No support for Intersects spatial query, needed for feature selection when
using the AJAX viewer (I hope to have this working soon). Envelope query
works though.
* Coordinate systems are not always recognized by MapGuide, requiring some
dancing around with the map setup to get the map to display.
* When connecting to Oracle, you may see a '~' instead of a '.' in the names
of some of your tables when shown in Studio. Don't worry about that, it's
fine.
 
The posted build may be unstable and/or not working for your particular data
-- it has 2 days of development in it so far.
 
Please refer to the README.txt, available in boths zips, for installation,
compile and usage instructions.
 
 
Traian
