Hi maybe this code can help you, this function receives a array with
positions and a distance and sets de extent of the map in order to show a=
ll
the features(points) you receive in the array.=0D

Asunto: [Mapserver-users] Center map on feature?=0D
=0D
I would like to ask the list for any ideas about how I can centre a map=0D
on a specific site/feature.=0D
=0D
We currently link from a site result page (generated from a database) to=0D
a map search page by grabbing the X,Y UTM zone 33 values for the site=0D
that we hold in the database. e.g. reference map link on page:=0D
=0D
http://www.fastionline.org/php/content.php?item=3D4&site_id=3D80&lang=3Di=
t=0D
=0D
will take you to the main map page centred on the site.=0D
=0D
However, we have recently begun to add sites that are in UTM zone 32. We=0D
project all this very neatly using mapserver. However, we need to think=0D
of a new way to link back from a single site to the main map centred on=0D
the site.=0D
=0D
Any suggestions would be very welcome. Every site has a unique id which=0D
is also present in our shapefile.=0D
=0D
Many thanks,=0D
