Re: [mapserver-users] Performance in regular expressions or an alternative way to select a list of features
Hello David,
I wasn't aware of the IN syntax. It looks cleaner, and hopefully will
be better. I think in the end I will try all sollutions and see which
one is the fastest for a given (large) expression.
Thangs again,
Adrian

Adrian,
One method that I have used is to use an IN statement in my expression
and then use a variable to populate the list of IDs in the statement.
I create a class like this:
CLASS
NAME Low
EXPRESSION ('[COUNTY_FIP]' in '%group1%')
OUTLINECOLOR 0 0 0
COLOR 255 204 204
END
And then in the URL calling the map, I include group1=27001,27003,27005
I actually use this with five classes (five different URL vars) to
create a thematic map of counties based entirely on data passed in
through the URL.
I have no idea on how the performance of this method compares to what
you have done, but it might be worth a try. There are only 87
counties in Minnesota, so that is the largest number it gets, but the
performance isn't bad.
David.

*Subject:* [mapserver-users] Performance in regular expressions or
an alternative way to select a list of features
Hello everyone,
Here's my problem: I'm trying to highlight segments from a line
layer by using an expression in a specific class. This portion of
the mapfile is dynamically generated and when it is done, it is
sent to mapserver for rendering.
My problem is that I have to select between 10 - 400 features at a
time and I noticed when I have a lot of features there is a severe
performance degradation in mapserver (takes a lot of time to
render or even times out).
Right now, my expression is built using regular expressions:
something like:
*EXPRESSION /^ITEM1$|^ITEM2$|^ITEM3$|^ITEM4$/*
This works ok, but as I said has a performance penalty when you
reach ~400 items. My data is selected from a shapefile layer
which has about 5500 items.
Since I wouldn't be using the regular expressions at full capacity
(I'm matching the full name), I might rewrite the expression using
something like:
*EXPRESSION ( ([NAME]==ITEM1) OR ([NAME]==ITEM2) OR
([NAME]==ITEM3) OR ([NAME]==ITEM4) )*
From the documentation I see that:
/Regular expression with MapServer work similarly to string
comparison, but allow more complex operation. They are slower than
pure string comparisons, but might be still faster than logical
expression. As with the string comparison use regular expressions,
a FILTERITEM or a CLASSITEM has to defined, respectively.
/I would like to know if there is an efficient way of selecting a
list of elements from a layer, or what are your recommendations.
Also - have there been significant changes in performance for this
issue from mapserver 4.10 (I am now migrating to mapserver 5.4)?
Thanks,
Adrian

Re: [mapserver-users] Performance in regular expressions or analternative way to select a list of features
Hello Steve, I haven't tried out the simplified regex so I don't know if it will be faster. I will try to test it as part of a speed test of the various methods... I'm not sure what you mean by writing a temporary set of geometries. Do you mean adding an index to my data so that I can select it by a different (grouping) field instead? Unfortunately I can't do that because the same item can be part of 10-20 groups, so there would not be an easy way to group items apart from duplicating them in the shapefile/dbf. I'm not sure if there's a problem if the same feature appears 12 times in the same shapefile. In the end data reorganizing might be the fastest method available. Problem is some items will belong to groups dinamically, so I will have to implement a selection mechanism based on item id... Regards, Adrian Steve Lime wrote: Have you tried a simplified version of your regex? I think you can do: EXPRESSION /^ITEM1|ITEM2|ITEM3|ITEM4$/ You might also consider writing a temporary set of geometries if a user will continually display from that set. In that case your overhead would be in managing the set of features which would be higher the first time but then very fast to render. Your dynamic portion of the mapfile would reference the temporary data.

[mapserver-users] Displaying a string instead of a label
Hi everybody, Can someone point me to the relevant part of the documentation/example that shows how to display a static string (set at the layer level) for a layer instead of displaying a label?

RE: [mapserver-users] Smaller polygon sizes when usingmapserver 5.4.1compare to 5.2.0
Hi Thomas, Please note, that this Mapserver behaviour (correct or incorrect) still exists in 5.4.1 version, when the GD library is used. The change of behaviour affects the rendering of the background when AGG library is used. Also, in the documentation, the use of BACKGROUNDCOLOR is regarded as creating a billboard effect. It would be nice to have capability to control the size (and appearance) of this billboard, which seems to exist in the older 5.2.0 version, but have been partially removed in the new 5.4.1 version. The other point was about the rendering of polygons. I would suggest to put some kind of a note or explanation for the 5.4.1 version, that when the OUTLINECOLOR is not specified, the polygon will be one pixel smaller in size in all directions, from the real one and to avoid this, the OUTLINECOLOR needs to be always defined either with the same colour as the rest of the polygon or with another desired colour.

Paul,
You may need to define your output projection instead of using AUTO (I
didn't know mapserver would tolerate that in the MAP section!).
And IMAGEPATH is the file-system path to a folder writable by mapserver.
Here's
an example using standard ms4w:
IMAGEPATH '\ms4w\tmp\ms_tmp\'
with IMAGEURL being its web-based equivalent (the same location on disk but
access via your web server):
IMAGEURL '\ms_tmp\'
since ms_tmp is set as an alias in Apache's httd.conf:
Alias /ms_tmp/ C:/ms4w/tmp/ms_tmp/

The PROJECTION in the MAP portion refers to your desired output map

RE: [mapserver-users] Mapfile displaying in red
Paul, Your polygon data is red because you are telling MapServer to color it red. In the class in your layer 'map' (probably not a great layer or class name), you are using a style to color your polygons. CLASS NAME 'map' STYLE COLOR 255 0 0 END LABEL TYPE bitmap END END You have set the value of the color property to be 255 0 0. Colors are set as RGB (Red Green Blue) triplets. In that line, you are saying, 'color it with the full amount of red and don't use any green or blue'. If you change the value to 0 0 255, you will see blue polygons. For an easy way to come up with prettier colors, take a look at ColorBrewer: http://www.personal.psu.edu/cab38/ColorBrewer/ColorBrewer_intro.html David. -Original Message- From: mapserver-users-boun...@lists.osgeo.org [mailto:mapserver-users-boun...@lists.osgeo.org] On Behalf Of Paul Curran Sent: Wednesday, July 15, 2009 5:20 AM To: mapser all users Subject: [mapserver-users] Mapfile displaying in red Hi When i load my map file which can be seen below i can view the outline of map but the actual map displays as red.

I'm going to put this into postgis, with srid = 3417, will that make any difference. Yes. (I'd like to avoid re-projections.. I think... don't I?) Reprojection isn't evil. You may as well do it right, but the main thing with postgis is that you put it in, and take it out, calling the same projection. Which could be -1 if you really don't know/care. MapServer doesn't set a layer's projection from postgis. If you have a layer(s) that's different from the map's overall projection, then you'd need to set the projection in the layer definition, not necessarily in postgis. Setting a layer's projection different from the map's projection is what will trigger reprojection. HTH, -- Richard Greenwood richard.greenw...@gmail.com mailto:richard.greenw...@gmail.com www.greenwoodmap.com http://www.greenwoodmap.com Ahh, so QGIS didn't export a projection that matched my data.

I'm on 10.5 and never played with 10.4, but I'll see if I can help as it's all just UNIX, right? :-) I'm also assuming that your directory definition was not copied, pasted and emailed correctly so the superfluous \ are not really in that file.

When I access my executable mapserv file from the command line, I get this: This script can only be used to decode form results and should be initiated as a CGI process via a httpd server.

Anyways, the problem is that in this cgi-bin I have my mapserv executable (though one of the things I'm thinking is that maybe I need to add something else to AddHandler to make it think that this file is executable?).

Re: [mapserver-users] GetCapabilities response being truncated
