Built-up area: how to sum up the area that is "built-up"

[MartinKoller]

Hi

I do have landuse data, i.e. shape file with ALL different landuses, but would like to sum up built-up area in certain buffers around rail stations. I did intersect the buffers with the landuse layer and therefore ended up with entries of all landuse polygons that intersect. Then I filtered the entries that belong to built-up landuse (= four categories out f about 20). After eliminating the non-built-up entries, I tried to sum up the entries that are built-up for each buffer. 

Is there an easer way, e.g. select the four categories and then sum them up for each buffer in one step, ending up with only one entry in the table for each buffer?

Thank you in advance.

Best regards,

Martin

My first thought is to take a look at the Tabulate Intersection tool found in the Analysis toolbox/Statistics toolset.  I think this does exactly what you need.

Otherwise, you could export your table to Excel and make a Pivot table.  There is a GP Pivot Table tool, but it doesn't appear to be able to sum areas for you.
