Hey!

For the historical study I am conducting, I have three layers with roads in 2000, 2008 and 2012 respectively. Only the data for 2000 is complete- i.e. there are additional segments of roads in 2000 that are not present in data for 2008 and 2012. I'm positive that roads did not vanish between 2000 and 2008 :p I would like to add the length of the additional roads from 2000 to that of 2008 and 2012, so that my data is correct and complete. How do I go about it?

Time is not in my favor and I would really appreciate some help. A BIG thanks to all those who would like to help me out :)

Hi MaryAnn,

You can perform the following workflow:

1.  Perform a Select by Location, selecting all roads from the Streets_2000 layer that 'contain the source layer feature'.  The source layer feature will be the Streets_2008 layer. Ex:

[ATTACH=CONFIG]33559[/ATTACH]

2.  Open the attribute table of the Streets_2000 layer and choose to switch the selection.  Now all the roads that are not within the Streets_2008 layer will be selected

3.  Append the selected features to the Streets_2008 layer.

You can then perform the same steps above for the Streets_2012 layer.
