I think the ArcSDE provider still supports it (3.3). It is also the one
that has geometric properties that refer to spatial contexts that do not show
up when I list the contexts from the connection until I used the activate

In any case, you should not use it since the geometric property's associated

Subject: [fdo-users] Clarification of Spatial Context <br>
<br>
<br>
I am trying to use FDO to connect to a variety of data sources. I am a little <br>
unclear about the coordinate systems. The connection will display available <br>
spatial contexts and a geometric property will indicate it's associated <br>
spatial context. I have noticed that the associated spatial context does not <br>
always appear in the connection's list until that context is set as the <br>
active spatial context. <br>
<br>
Are the geometry data returned in the coordinate system identified by the <br>
geometric property's associated spatial context or are they converted to one <br>
that is identified as active on the connection? Do I have to set the context <br>
on the connection each time I do a fetch of a geometry? For example, I am <br>
accesing two different shapefiles and they are in two different coordinate <br>
systems and I am a bit confused on how to properly work with the contexts. <br>
