Re: [pmapper-users] Hello!
Hi, I've made a hack in pmapper few years ago. This one allows you to specify 2 data sources for each layer: LAYER . DATA the_geom FROM your_heavy_view USING UNQIUE gid METADATA PM_RESULT_DATASUBSTITION the_geom FROM your_geo_table USING UNQIUE gid ... END ... END For instance your_heavy_view is a view that join a geographical table (your_geo_table) with many other tables. The attributes the_geom and gid have to be the same names and values in both table and view. The DATA value is the habitual one whereas PM_RESULT_DATASUBSTITION is used to draw / select / query graphically / etc... to speed up pmapper. Be careful : all attributes used for label, classitem, binding, etc.. have to be in the main table. It has only been tested with postgreSQL/postigs but could works with other data types.

Hi, Yllka Interesting topic! If possible, don't forget to show us your final results! Thomas Thanx, very interesting tip! Should try it asap! (On your example, beware on the UNIQUE typo ; ) With a Shapefile, using an index file (QIX) speeds up data visualisation for sure.

Re: [pmapper-users] Hello!
Put the generated/temp files from Mapserver on a RAM disk (IMAGEPATH parameter of the mapfile). Have you got doc for this point please? Here under how it is set up on my Debian server, for a 8GB directory on RAM: mkdir /data/disk_on_ram/ mount -o size=8G -t tmpfs tmpfs /data/disk_on_ram/ mkdir /data/disk_on_ram/pmapper_temp chown www-data:users /data/disk_on_ram/pmapper_temp/ Then to let Apache use it: In /etc/apache2/httpd.conf Include /etc/apache2/pmapper_tmpdir.conf In /etc/apache2/pmapper_tmpdir.conf #Alias /tmp/ /data/dataweb/tmp/ Directory /data/dataweb/tmp/ AllowOverride All Options All Order allow,deny Allow from all /Directory In /data/dataweb/tmp/ ln -s /data/disk_on_ram/pmapper_temp/ Finally in the mapfile: IMAGEPATH /data/disk_on_ram/pmapper_temp/ IMAGEURL /tmp/pmapper_temp/ For Raster data, you can use tiles (use gdaltindex) and then create the QIX file. Also with raster data, gdaladdo is very usefull as it adds pyramidal / less detailed views of the image (downsampling), in the image itself. Mapserver knows how to use them depending on the scale of the map.

Re: [pmapper-users] Hello!
Thankyou all for the responses... I have evidentet these techniques: - Slippy Maps (that is integreted in MapServer but i will show how it works) - Zooming layering (show only some maps in some zooming levels) - Tile Index ( i love it) - Database optimisation (i have an experience with thousands geospaical records ...so i think it is important) I will take into consideration your advice too... I will send my paper in two conferences here in Balkan. The rule is to not publish the paper until they make a decision to accept it or not So I will show it up for you after May 2013 :) On Mon, Feb 18, 2013 at 10:27 PM, Armin Burger armin.bur...@gmx.net wrote: http://mapserver.org/optimization/index.html http://mapserver.org/input/raster.html#raster-display-performance-tips On 02/16/2013 06:35 PM, yllka baci wrote: Hello Pmapper users I'm going to write a paper on techniques that speed up data visualisation on Web GIS applications.
