<DIV><FONT face=Arial size=2>Hi Guys,</FONT></DIV>
<DIV><FONT face=Arial size=2>I have a vector map with three layers added. the
output from a v.category map=parcel op=print layer=1,2,3|more looks like
this:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial
size=2>12|1|1<BR>24|2|2<BR>28|3|3<BR>34|4|4<BR>42|5|5<BR>42|6|6<BR>45|7|7<BR>247|8|8<BR>247|9|9<BR>443|10|10<BR>548|11|11<BR>749/833/834/835/836/837/838/839/840/841/842/843/844/845/846/847/848/849/850/851/852/853/854/855/856/857/</FONT></DIV>
<DIV><FONT face=Arial

<DIV><FONT face=Arial size=2>1692/1693/1694/1695|18|17<BR></DIV></FONT>
<DIV><FONT face=Arial size=2>where the first column gives the cat of layer
1, second column gives the cat of layer 2 and third column gives the cat of
layer 3. The series of cats in the first column separated by "/" are the cats of
stacked polygons in layer 1.</FONT></DIV>
<DIV><FONT face=Arial size=2>Now I want to do get a count of all features in
layer 1 for a given cat in layer 3. As you can see from above some of the cats
in layer 3 will be linked to more than one features in layer 1 so how can i get
these number of features in layer 1 for each cat in layer 3.? This will help me
to identify all stacked polygons.</FONT></DIV>
<DIV><FONT face=Arial size=2>Any help will be deeply appreciated.</FONT></DIV>
<DIV><FONT face=Arial size=2>Thanks and regards</FONT></DIV>
