Query new features in polygons

NigelDsouza — Tue, 08 Sep 2015 09:09:38 GMT

Hi,

I am trying to develop a Add In that will help the user automatically point out changes in a new layer(Polygon).

Case: I have two feature classes of state polygon data say. One feature class is old and the second is new. I need

to some how compare the two layers and select features in the new layer that do not exist or have been modified in the old layer.

I have to do this spatially. I am currently using overlap for starters...

How can I achieve this using arcObjects?

Regards,

Nigel.

1) One way to keep track of changes in features residing in a geodatabase is to use versioning. Please refer to the topics below:

(ArcObjects Help)

2) Your other option is to use Replication. See the topics below about replication in the ArcGIS Desktop Help and ArcObjects Help:
