[mapserver-users] Comparing cgi and fcgi for serving aerial images
I made some tests by letting JMeter run a few thousand WMS GetMap requests with varying BBOX and WIDTH and HEIGHT parameter. I tested three alternatives: MS4W 2.2.8 and Mapserver 5.2.1 MS4W 3.0 beta 7 and Mapserver 5.6.0 as cgi MS4W 3.0 beta 7 and Mapserver 5.6.0 a fcgi Server is Windows 2003 server with 8 cores and fast disks. I configured JMeter to use 20 threads I feel I was able to get fcgi running by following the instructiuons of MS4W README_INSTALL document. I believe it is convinced by a) calls addressed to /fcgi-bin/mapserv.exe work and b) after receiving an image from WMS service the process remains on the server for some time. However, all these three alternatives are giving me about the same speed that is 5 images per second or 500 KB/sec with jpeg output. Bandwidth is not the limiting factor because with 24-bit png output I get a throughput of 4400 KB/sec. It looks like I am having some base load in my system that takes about 150 milliseconds per each successful WMS request and using fcgi does not help in my case. Can anybody suggest why my server is so much slower than the one used in Mapserver/Geoserver shootout http://www.slideshare.net/gatewaygeomatics.com/wms-performance-shootout and why I do not get any advantage from using Fast-CGI? Could it be because my tileindex shapefile is rather large with more than 11000 polygons? Images themselves are processed in a standard Mapserver way and they are uncompressed, tiled geotiffs with external uncompressed overviews. Some evidence about tileindex handling eating time is that I can get double speed with 10 images per second from a single ecw file but this test is not very comparable because my ecw file is black and white and not 3-channel as my geotiff layer. -Jukka Rahkonen- ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
[mapserver-users] Query Error in getFeatureRequest on Oracle DB
Hello,
I have a layer that gets its data from an Oracle database. The layer can
be visualized without any problems.
As soon as I send a getFeatureRequest, the following error message appears
msOracleSpatialLayerGetItems (): Query error. Can not retrieve column
list
In the UMN log file are 2 SQLs. The one with the spatial SQL query works
with the
Oracle Developer and I get a result. Why doesn't get my UMN (version
5.2) any data?
Thanks for your support!
Regards
Stefan Schantz

Re: [mapserver-users] Comparing cgi and fcgi for serving aerial images
It's hard to give a definite answer without seeing your actual setup, mapfile, data, etc. However, as a general rule, you will gain from using fastcgi only once you get to the point where the processing time for each request (to read data and render the map) becomes close to or smaller than the time it takes to launch CGI processes. So if you get around 5 hits/sec with 8 cores, we can presume that each request takes over 1 second of processing time (and/or disk I/O) which is several times larger than the time to launch a CGI process, and you need to do some work on your data and mapfile before you can benefit from fastcgi. Of course I could be completely wrong, but I'd suggest you start by verifying where the time is spent by enabling MS_ERRORFILE/DEBUG at both the mapfile and layer level, look at the logs to identify where the time is spent and optimize your mapfile/data accordingly.

[mapserver-users] attribute bindings for SYMBOL and FONT?
The short story: Is it possible to bind a CLASS's SYMBOL object to an attribute (i.e store the symbol name as a attribute of a feature)? And the LABEL objects FONT name? The Long Story: --- I've been working with the yet-to-be-released Feature Editor in Geomoose v2. It allows the user to digitize features (points, lines, and polygons) and assign attributes, then stores them in PostGIS. I want to allow simple styling and don't want to have a map file the size of War and Peace, so I thought I would use the attribute/item/column binding abilities of Mapserver's CLASS and LABEL objects. To that end, one of the columns the feature table will be style name (or maybe feature class), which I'll use to join to a style table (with COLOR, WIDTH, etc columns) to get the feature rendered in a simple style. After a quick review of Mapserver's doc, most of the most important objects can be bound to attributes, with two exceptions, SYMBOL 'name' and FONT 'name': CLASS STYLE ANGLE [angle] COLOR [color] #R G B OUTLINECOLOR [olcolor] #R G B SIZE [size] WIDTH [width] # v5.2 SYMBOL 'name' # in SYMBOLSET END #STYLE TEXT ([label]) LABEL ANGLE [label_angle] COLOR [label_color] OUTLINECOLOR [label_olcolor] PRIORITY [label_priority] SIZE [label_size] FONT 'name' # in FONTSET END #LABEL END # CLASS How difficult would it be to have attribute binding for SYMBOL and FONT?

Using metatiles (that is, a tile rendered intentionally large and then

TileCache support that type of processing.

RE: [mapserver-users] How to draw a circle using MapScript?
Here's an example that draws a 1km diameter two different ways:
http://maps.dnr.state.mn.us/mapserver_demos/circles.map
It shows two ways to do this. One using a circle layer and the other using a
circle symbol but with different size units (e.g. non-pixel).
Apparently a circle layer takes features consisting of two points where the
points are on the circle and directly opposite one another. Their mid-point
defines the center point. Why I did it this way is a bit of a mystery but it is
what it is...
The buffer method is also perfectly valid.

In another approach, I believe MapServer wants you to define a bounding
box for the circle by creating a line shape with the first point at the UL
coordinate of that box and the second coordinate at the LR coordinate of
the box. So you'd offset your center point .5 KM to create those points.
You can add the resulting shape to the appropriate layer to draw it.
I'll check to make sure, but I think that will work.

Exellent! Now on to WFS-T-free feature editing!
Binding would be with style'symbol, instead of class symbol. Font
also
can be bound. I will update the docs to reflect that. The list of
binding elements is:
For style:
SIZE, WIDTH, ANGLE, COLOR, OUTLINECOLOR, SYMBOL, OUTLINEWIDTH,
OPACITY
for labels: SIZE, ANGLE, COLOR, OUTLINECOLOR, FONT, PRIORITY

Using metatiles (that is, a tile rendered intentionally large and then
clipped) is one way around problems like this and tiling tools like
TileCache support that type of processing.

Dear MapServer users..
I have an issue with the rendering of lines at tile borders on my map,
which is exactly like this picture:
http://crschmidt.net/mapping/mapserverbug.png
Being a new MapServer user, I checked previous threads related to this
problem and found some suggestions to use TileCache or OpenLayers etc
The
threads were pretty old (like 2007..2008), so I would like to know if
there
is any other solution to the problem I am facing now.
More info:
CLASS
NAME 'Others'
EXPRESSION ('[class]' eq 'AU' OR '[class]' eq 'GR' OR
'[class]' eq
'PV' OR '[class]' eq 'TR')
MAXSCALE 32000
MINSCALE 16001
STYLE
COLOR 255 160 122
WIDTH 5
MINWIDTH 5
MAXWIDTH 6
ANTIALIAS TRUE
END
END
I use version 5. Please advice me on how to proceed. Thank you very
much
Regards
