[mapserver-users] How can i get an attribute value of a specific shape in the mapfile?
Is there any way to get an attribute value of a specific shape in the mapfile? For example: I want to know the value of the attribute 'AREA' of a shape whose 'NAME' is 'REDFERN'. So that I can use it in the EXPRESSION like this: CLASS EXPRESSION ([AREA] > [the area value of shape whose name is 'redfern']) ...

[mapserver-users] Re: passing values to mapfile
Thank you so much. I'm just looking into it. It says 'You can use runtime substitutions to change values within a FILTER as you go'. Can do it within a EXPRESSION? Cause I was trying to do the substitution within a EXPRESSION. But it seems not work. (no error) What I did is: EXPRESSION ([AREA] > %grade%) then ...&grade=1000&... Or I can only substitute the whole expression statement? I tried: EXPRESSION %expression% then &expression=([AREA]>1000)&... But I got an error message 'getSymbol(): Symbol definition error.

[mapserver-users] efficiently displaying daily changing vector data
I have just finished reading the following thread Mapserver - User - How to display vector symbols (direction and magnitude) in MapServer? http://osgeo-org.1803224.n2.nabble.com/How-to-display-vector-symbols-direction-and-magnitude-in-MapServer-td1971531.html Two questions -- 1. What is the most efficient way to display vector data that comes to me on a daily basis as text files. I have x,y, length and angle information in these text files (along with some other info). I guess, I will have to massage the files to convert them to clean CSV with only the first line containing the column names. Then I can access the file as an OGRVRTDataSource. Or, should I insert the data in a Pg table and then use that? The files will be refreshed daily, so the processing needs to be done only once a day. 2. The thread above makes a mention of a Mapfile CLASS definition like so CLASS SYMBOL 'arrow' ANGLE [Rate] SIZE [Az] COLOR 0 0 0 END Is there an arrow symbol definition that I can use, or is that only possible with truetype fonts?___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users

[mapserver-users] Limits on CLASS EXPRESSIONS for regular expressions
Does anyone know if/what restrictions we have on regular expressions within mapserver. I have a perl regular expression that matches 44 of 120 counties in Kentucky: EXPRESSION /(?-xism:(?i:(?=[abcfghjlmnorstw])(?:b(?:o(?:y(?:d|le)|urbon)|u(?:llitt|tler)|(?:arr|rack)en)|c(?:a(?:rter|sey)|(?:hristia|rittende)n|lark)|f(?:ayette|leming|ulton)|h(?:a(?:ncock|rt)|enderson)|l(?:e(?:tcher|wis)|(?:incol|oga|yo)n)|m(?:a(?:di)?son|e(?:rcer|tcalfe)|o(?:ntgomery|rgan)|ccracken|uhlenberg)|s(?:helby|impson|pencer)|t(?:aylor|odd)|w(?:ayne|oodford)|adair|grant|johnson|nicholas|oldham|russell)))/ This has been optimized and uses some embedded modifiers. This works fine in Perl but does not match anything in mapserver. Any thoughts on how to modify this to work with mapserver. While this looks very convoluted, it is generated from a list of words and is high efficient when matching.

[mapserver-users] MapServer Map Files and GeoTools
Hi All,
Was great to see some of you at Foss4G. As you might know, I'm a committer on
the MapFish print module and am really interested in excelling the development
of that. Hopefully I can get some time to do so. To get to the point:
We use MapServer as our main WMS to build our caches and for printing maps.
Currently an SVG is downloaded by the print module and then rendered onto a
Graphics2D object inside the module and then rendered onto a PDF document with
iTextPDF. We would like to make this process a bit slicker and render from
PostGIS directly with the help of the style defined inside the map files. An
idea inspired by Jesse Eichar was that we use GeoTools and include it as a
dependency to do the heavy work for us. But does this mean we would need to
implement parsing the map files somehow or is there already functionality for
that inside GeoTools?
I found this on the MapServer docs (sorry for the HTML email, but I thought
it's more readable... http://mapserver.org/ogc/sld.html):
PHP/MapScript Example that Generates an SLD from a Mapfile
The following is a small script that calls the generateSLD() function to create
an SLD for a specific layer in a mapfile:

getLayerByName("parcel");
// force visibilty of the layer
$oLayer->set('status', MS_ON);
// generate the sld for that layer
$SLD = $oLayer->generateSLD();
// save sld to a file
$fp = fopen("parcel-sld.xml", "a");
fputs( $fp, $SLD );
fclose($fp);
?>
Is there a way to use this functionality with GeoTools or another Java library?
Thoughts are appreciated.
Cheers,
Tim

This is an older version of MapServer, MS4W 2.3.1, MapServer 5.2.1.

Not sure what you meant by label output. But here's what I see- on the web application, the labels are as they should be- they have the background halo. On the printed map, the label text itself appears, but no background halo.

For performance, you will want the imagery pre-warped into one spatial reference system. (The same SRS as your output SRS.) I don't know if you will want the output SRS to be one of the two UTM Zones, or if you want to choose a different SRS.

For instance would using Typename=Traseer give me all of the geometries in the BBOX, but Typename=Traseer, Punkter will give me all in Punkter, but only some geometries from Traseer. Is it supposed to be that way? Any other way I can query a BBOX on multiple layers without running a WFS request per layer? Thanks in advance!

The problem is that both images are showing up in the same UTM Zone.
