[postgis-users] How are you editing data in PostGIS?

[Ryan Proulx]

Hi Eric,
 
Just a note of correction. FME does support reading of AutoCAD Map
Object Data through Autodesk's own API. The restriction upon this is
that you need to have AutoCAD Map installed adn the correct edition of
FME as well. 
 
Additionally, support for AutoCAD 2004 reading is now in progress.
 
Regards,
ryan

	Hi Mark,
	 
	I earlier developed an AutoCAD Map VBA application that can
import data from AcadMap into PostGIS using ODBC/ADO
	The application reads a configuration file, which can be
customized via GUI. This lets you set up the mapping between AutoCAD
layers and most AutoCAD specific graphical attributes to
PostgreSQL/PostGIS tables/columns. You can also configure mapping of
object data.
	 
	As an FME user I figured I soon wont need this anymore since FME
now supports PostGIS, but FME doesn't yet support AutoCAD Map Object
Data, ufortunately.
	 
	If you're interested I can send you a snapshot of the GUI and
also the .bas files for you to try out. It was developed for PostgreSQL
7.2.x, but shouldn't require much work, if any, to work with 7.3
	 
	I have also developed a check-in / check-out VBA application in
AutoCAD Map. I was planning to do this as a true/live editing client to
PostGIS, but the event handlers in AutoCAD Map were just too unstable so
I gave up. Instead my application can check out an user specified area
(either by box, or other means) and then store all identifiers of
checked out objects in a separate table. During check-in the data is
compared to that table, and any new objects, deleted objects, updated
objects, are detected. New and deleted objects were easy, but we had to
compromise for the updated objects, telling the operators to insert a
code to indicate update in an AutoCAD object data field.
	This application is not that generic, and it's based on the now
obsolete RDO. But if people are interested I might spend a day or two to
shine it up and try to make it more reusable.
	 
	regards,
