CUT TO SHAPE (NEW SHAPEFILE)

BernardoSilva — Thu, 17 Apr 2014 02:24:12 GMT

Hi,
Hope someone could help me out with this:

I have 2 shapefile:
SHP#1: Countries' Boundaries
SHP#2: World Ecoregions (polygons extend over country boundaries)

I would like to create a NEW shapefile with the Ecorregions (SHP#2) inside a SINGLE country from SHP#1.
So, cutting the SHP#2 polygons by a country in SHP#1 making a new shapefile with corresponding SHP#2 attributes.

A New shapefile showing only the Ecorregions within Country A, so I can later realize an area analysis for the ecoregions within Country A.

Thanks,
Bernardo.

Try a Union (http://resources.arcgis.com/en/help/main/10.1/index.html#//00080000000s000000) I think this does what you want.
It "merges" the to shapes into one bringing the shapes and attributes together.

Just did it adding a field in the attribute table and "Calculate Geometry" but the results are definitively wrong. Showing numbers too small for the respective areas. Any help here please.

Worked it out. It was a projection problem.
