All,
So, I’ve got my cool LISP output template working nicely. I even have
more than one Layer working from a single Template, but, I just
discovered that if a line does not originate or terminate inside of my
BBOX of interest, then it’s not considered part of the result set.
The question is (and I bet this is going to be related to my datasource,
which is Postgres) is there a over-ride that can be used in MapServer
for grabbing from the Postgres service based on a crossing window vs a
within (features completely within) the window of interest? A slighting
related piece would also be, would I get a clipped feature, or the real
feature no matter where the BEGIN/END nodes were located?
I think I can modify the SQL in the connection to do the crossing
window, so I’m not out completely here.
What is you current sql that is not getting the features that cross the
window?
I've never had a problem like that with mapserver, so I'm wondering how
you are generating the problem.
Mapserver has substition variable like !BBOX! or something like that
which gets replaced with the BBOX of the window getting requested.
geom from (select * from table where geom && !BBOX!) using ...
I don't remember the exact syntax off the top of my head, but give me a
shout if you can't figure it out.
