AW: [mapserver-users] Re: symbol position moving when using angle
Hi Bart, may be this is what you are looking for: From the map file documentation: LABEL ... POSITION [ul|uc|ur|cl|cc|cr|ll|lc|lr|auto] Position of the label relative to the labeling point (layers only). First letter is Y position, second letter is X position. Auto tells MapServer to calculate a label position that will not interfere with other labels. With points, MapServer selects from the 8 outer positions (i.e. excluding cc). With polygons, MapServer selects from cc (added in MapServer 5.4), uc, lc, cl and cr as possible positions. With lines, it only uses lc or uc, until it finds a position that doesn't collide with labels that have already been drawn. If all positions cause a conflict, then the label is not drawn (Unless the label's FORCE a parameter is set to true). Auto placement is only available with cached labels.

RE: [mapserver-users] Mapserver 6.0 regex
Hmmm... A plain 'ol regex expression did not change between 5.6 and 6.0, so
this is still valid:
FILTERITEM 'myitem'
FILTER /myregex/
Where regex's changed is inside logical expressions:
FILTER ('[myitem]' ~= /myregex/) becomes FILTER ('[myitem]' ~ 'myregex')
There are regression tests for these cases (query/filters.map) so I'm pretty
sure MapServer proper is working ok. You might try setting the filter and
filteritem directly in the mapfile see if that works. If it does then it's
likely a problem with PHP/MapScript.

Subject: [mapserver-users] Mapserver 6.0 regex
I have one (hopefully the last!) problem with migrating from Mapserver 4.6 to
6.0, this time over the use of regex.
Using Mapscript on a Fedora platform I have been setting a filter in this
manner:
$map=newMapobj(/var/www/vhosts/mysite/httpdocs/test.map);
$layer1=$map-getLayerByName(test1);
$layer1-set(filteritem, Attribute1);
$layer1-setFilter(/target/);
This worked fine, but not anymore. I see in the migration guide that a regex
should now be delineated as a string so I assume that /target/ should become
target. But that doesn't work either.
I am wondering if part of the problem is that as well as going from Mapserver
4.6 to 5.0 I also changed from Fedora to Ubuntu 10.04, and I see from the
Mapserver documentation on Expressions that the OS may affect regex operation.
Am I missing something obvious here? I am really tired of going in circles
over this...

Re: [mapserver-users] Asking for guidelines about a project
Mainly because adding a new vehicle is trivial from a site maintenance perspective if you have all vehicles in one table. Adding a table would likely mean you would need to add a layer in Mapserver, but it depends on your user interface needs. For my first implementation, I did have some concerns regarding performance if I put all the historical positions in a table with the current positions. That's why I had two tables: current_position table with about 6 to 20 rows (since I have 6 to 20 vehicles), and an archive_positions table that grew over time. Since the user was usually just concerned with displaying the current position, queries were handled very quickly. As it turned out, the archive_positions table grew to only several hundred thousand records (maybe a million?), and Postgresql had no problems with that. So if I did it again, I'd likely use one table, containing the current and historical positions. But as I mentioned earlier, it might depend on how may vehicles you anticipate tracking, and how often they report (and to some extent how fast they move). Do you have that information?
