Hello,

 

I have a network of pipes with different diameter; With "lineonline-overlayer" I seperate points, which have the attributes from the pipes and the attribute "overlaps". This attribute overlaps can have a value from 2 to 5. So at this points meet minimum 2 and maximum 5 pipes. With "list_exploder" I can create at the same place more than one point, so 2 or 3... until 5.

 

Question: how to compare the overlaying points in case of looking for different diameter? the restult should be ONE point on this place where the diameter of one of the points is NOT the same.

 

thanks and regards,

 

oman

Hi Oman,

 

 

Does the Matcher help you?

After the Lineonlineoverlayer all attribut4es are in the list for wich u entered a listname.

 

U can use for instance a listhistogrammer on YourList_Diameter attribute.

 

ListSort  _historgram (default name in histogrammer transformer) ascending.

 

and check if listindex(0) in histogram >1.

 

 

Or after explosion u could test for overlaps >0 and use a statisticcalculator grouped on diameter, xcoord and ycoord (check all 3). Choose count. You could then do some other counting etc.
