Comparing 2 datasets

Hi,

 

 

Here is the scenario

 

 

1.  I am getting some data (ie. manhole data in .shp format)

 

2.  I use FME to transform the data to fit into a feature dataset in our SDE server

 

3.  A year later I get a new .shp of the same data from #1

 

 

Does FME have the ability to compare what is in SDE with the new .shp and only import the features from #3 that are different from what is already in SDE??  Either attributes, spatial, or both may have changed.

 

 

In the time between #2 and #3 there could have been edits to the data in both SDE as well as in the .shp.

 

 

I guess it's sort of an SDE Reconcile/Post.

Hi,

 

the short answer is yes it does :) look for crc matcher and the change detector.

 

the are some issues you should consider such as the definition. Of a changed object  and decimal accuracy for a start.
