Hi Andrea,
Will you please share snippet of one working example of Either COUNT or SUM
function ? This would help a lot.
- count < 100 red color
- count > 100 and count < 1000 green
- count > 1000
Thank you.

Hi Andrea,
I just tested with below version, it seems as you said MIN and MAX only
works. Received same error since I am using shape files as backend unable
to get what I want, with mysql / postgres I would have create sql layer.
- GeoServer Version2.21-SNAPSHOT
- Git Revisionade1dd70a986
Hmm.. not sure there is a process that will work for you, on a stable
version of GeoServer.
The Aggregate process can do counts, but in order to paint a map, you need
to aggregate
on the geometry as well (otherwise it's not part of the aggregation
output), which does not work.
It was solved recentl
Hi Andrea,
Thanks for reply.
I was attempting below, as you can see I was attempting to count stations
at specific location ( group by latitude, longitude ), Kindly find attached
screenshot. similar to SQL
select count(1) from sometable group by latitude, longitude.
As per process documentation (look at the DescribeProcess output):
"The aggregate operation to be computed, it can be MAX or MIN"
This process selects for each group just one feature, the one that has
either the min or the max value of a given attribute
sum or count make no sense in that context.

How does this relate to your expectation?
