You have complete control over the legend this way and can mix and match data sources however is required without needing to actually map the data out. It is more work overall, but if your MapFiles don’t change often, it’s usually a one time setup thing. I have a few map layers that have 7 or 8 different thresholds for display set MIN/MAXSCALEDENOMs and they all get a dummy layer that displays the same thing for all thresholds.

Re: [mapserver-users] MODE=legendicon GROUP Layers
Thanks for the info Steve, that makes sense - when Groups are used to link related layers things get too ambiguous. We'll look at our options with this one.

I think It would be possible to add support to see if a group name can resolve to a single layer based on scale but that doesn't exist in the code at this point.

Re: [mapserver-users] MapCache - A way to reduce BerkeleyDB Cache size ?
Hi Thomas So size looks really good.

Salut Ludovic, hi Andrew, I've investigated a bit more on the disk space issue with berkeley db backends, and here are some of my findings. To summarize, the space occupancy/efficiency is closely tied to the size of the images stored in the cache, and the configured pagesize of the bdb backend. For a cache that contains many empty tiles, i.e. that are just a few hundred to a couple thousand bytes, here are the space occupancies (the disk cache uses 4k blocks). This is for reference only, usual caches will not resemble this one. Also note that the disk cache was not configured to symlink blank tiles, and that the bdb cache backend has some code in it to reduce the tile data stored on empty tiles. disk: 197M bdb pagesize=64k: 106M bdb pagesize=4k: 96M bdb pagesize=1k: 73M sqlite: 103M mbtiles (sqlite with blank tile detection): 62M So these numbers actually aren't so bad for bdb in all configurations, but in this case the 4k filesytem blocksize is really inefficient. These are the occupancies for another tileset, where the tiles are much heavier (tiles around 40-45k). There are also quite a few empty tiles. disk:153M bdb pagesize=64k: 209M bdb pagesize=4k: 148M bdb pagesize=1k: 144M sqlite: 140M mbtiles (sqlite with blank tile detection): 137M I had initally stayed away from using small pagesizes in the bdb backend because of some stability issues, but in the current tests I have not run into any issues. From these tests, I think the natural way forward is to change the default pagesize, and maybe make it configurable in mapcache.xml as an advanced configuration option. If you are able to confirm my findings on your instances, that would be great. To set the pagesize you'll have to recompile/reinstall, after having changed lib/cache_bdb.c by replacing #define PAGESIZE 64*1024 by #define PAGESIZE 1*1024 near line 50. regards, thomas On Wed, May 23, 2012 at 3:55 PM, Ludovic Gnemmi lgne...@rgd73-74.fr wrote: Hi list, I would like to experiment Berkeley DB cache type but i'm surprised of the resulting db size compared to sqlite cache type.

[mapserver-users] OUTPUTFORMAT PDF rendering issue
Hello Folks, I was wondering whether someone may be able to help me. I'm currently trying to set up a WMS to create a topographic base map of New Zealand using Mapserver. So far, things are going ok, but have run into an issue when trying to get things into a format for high quality hardcopy printing (vector PDF). The issue arises with 'spikey' rendering of polygons when using Mapserver to output to PDF. When outputting as an image (PNG), the maps are drawn correctly, but when choosing PDF, the output looks sort of generalised and inaccurate. The data I'm testing with is a polygon version of the coastline of NZ, at a 1:5 scale - stored in a PostGIS database. I have played around with the mapfile settings of RESOLUTION in combination with SIZE - when using the default RESOLUTION of 72, the output is spikey, as described, but as I increase this number - the output gets progressively better. When I increase this to a very large number (16000) (with a SIZE of 9600 9600) - the output I get looks to be closer to the original dataset, devoid of spikes. I may be missing something obvious, so apologies if I am, but is this the correct way of getting a high quality output to PDF? I have tried this with the latest version of Mapserver - 5.6.5 and also with the latest SVN version built with support for using the CAIRO rendering library. Mapserver is built on Ubuntu 10. Any help would be much appreciated. Many thanks Andy ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
