Re: [mapserver-users] how to render labels on lines?
Hello Sergey, Using ANGLE FOLLOW in the label block will provide labels that follow the curvature of the line segment that is being labelled. Please note, that if the line segment is shorter than the label, the label will hang off the end of the line unless you use MINFEATURESIZE AUTO in the label block as well.

[mapserver-users] [SOLVED] Mapserver ./config with with httpd executable
Thanks everyone for help. I was following the documentation here for Linux compilation: http://mapserver.org/installation/unix.html My apache2 executable is not called httpd but rather apache2 and is located in /usr/sbin. I'm not sure if this is because apache2 is a newer version, or the package installer defaults to this naming, or it's a Ubuntu Linux thing. But i'll figure out the why later.

Re: [mapserver-users] Label text always clipped by tiles
I came into this conversation a bit late, but... So you're tiling, and using MS as your backend. Are you using TileCache or similar in between? If so, TileCache supports meta-tiling which may help your label problems significantly. Using meta-tiling, TileCache requests a much larger tile (say a 5x5 tile) and slices it up. Thus, MapServer generates fewer tile edges and truncated/missing labels. That's aside from the obvious benefits of caching your tiles, if your layer isn't subject to change often such that caching is appropriate. -- HostGIS, Open Source solutions for the global GIS community Greg Allensworth - SysAdmin, Programmer, GIS Person, Security Network+ Server+ A+ Security+ Linux+ PHP PostgreSQL MySQL DHTML/JavaScript/AJAX No one cares if you can back up — only if you can recover. ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users

Correct; there would be FEWER labels clipped (if you force them and allow partials) or missing (if you disallow partials). How many fewer, depends on how large you make your meta-tiles. If they're 5x5, that's a significant reduction in the number of tile edges.

Hi, I met the edge issue when I had to produce statistics maps with proportional symbols.

Re: [mapserver-users] Label text always clipped by tiles
Let's see: For starts, set PARTIALS FALSE and FORCE FALSE in the mapfile. That would prevent truncated labels, which would be worse than missing labels. (presumably) You may also want to add MAXSIZE 2048 to the mapfile, an element of the MAP object. This would allow 5x5 (1280) tiles, as opposed to the default which I think is 1024. The tilecache.cfg looks good too.

Re: [mapserver-users] Label text always clipped by tiles
My problem is that I need ALL labels to be complete and visible. I don't think that's possible if you're using tiles. Somewhere, some label will be close to a tile boundary and be truncated or omitted. If you find a mapping engine that can place labels like that (drawing half of a label on tile A when the point is on tile B) I would be interested to hear about it. -- HostGIS, Open Source solutions for the global GIS community Greg Allensworth - SysAdmin, Programmer, GIS Person, Security Network+ Server+ A+ Security+ Linux+ PHP PostgreSQL MySQL DHTML/JavaScript/AJAX No one cares if you can back up — only if you can recover. ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users

If you mean overlaying your data atop Google, say a small dataset expressable as KML, that should work A-OK. If it's pure vector data being rendered client-side, tiling wouldn't be an issue at all. But of course, that's where we leave MapServer Land and get into Google Earth, Google Maps, etc. If you mean how did Google do it? on their basemap I don't know entirely. They seem to have avoided (or later corrected) a lot of tile-edge artifacts. Their mechanisms probably included a) a mapping engine that positions labels to geographic points; b) large-scale meta-tiling with terabytes of RAM; and c) a large staff of personnel for QC and a few years of correcting reported issues. -- HostGIS, Open Source solutions for the global GIS community Greg Allensworth - SysAdmin, Programmer, GIS Person, Security Network+ Server+ A+ Security+ Linux+ PHP PostgreSQL MySQL DHTML/JavaScript/AJAX No one cares if you can back up — only if you can recover. ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users

I set metaBuffer to 100 and I'm seeing this in MapServer's log: msDrawLabelCache(): labelcache_map_edge_buffer = -100 But tilecache always passes a width and height of 256 in the URL to mapserver.

I have three layers; polygon, line and text (point). I get better results when I combine all three layers into one OpenLayer layer than when I move the text layer into its own OpenLayer layer.

Re: [mapserver-users] Label text always clipped by tiles
labelcache on is the default setting, and will apply for all layers where you have not set FORCE TRUE on your labels. if you don't want overlapping labels, this should be left as is. when tiling, you should *always* set PARTIALS FALSE on all your labels. - the metabuffer tilecache option should be set, to avoid artifacts on lines due to the the line caps that can be set. it will not have an effect on cut labels. when setting this option, mapserver *must* be configured with its labelcache_map_edge_buffer set to the same value as the tilecache metabuffer, so it will not put labels in the area that will be cut off by the metabuffer. - metatiling has an effect on the number of labels that can be displayed, in the sense that it is easier to display labels in a large image than it is in a 256x256 tile. as for your requirement of having all labels appear, without overlapping, and being continuous across tile boundaries, I'm afraid this is physically impossible to obtain. regards, thomas On Wed, Jan 26, 2011 at 21:43, Rahkonen Jukka jukka.rahko...@mmmtike.fi wrote: Hi, I have never done this kind of label stuff myself, but Mapserver documentation seems to say that first the LAYER should have LABELCACHE ON before other advanced features have an effect.

Much thnx to Jeff for his reply. I ran $ ldconfig -v /tmp/ldconfig.output.txt 21 I found libodbc* in the output to be in exactly the same directories as when I run $ sudo find / -name libodbc* So as far as i can tell this means gdal-config is saying my libodbc* libraries should be one place when they are somewhere else. Makes sense that mapserver is errors out on make. Not sure how that happened. I tried editing the Makefile after configuring it to account for these differences but just got the same error. I then tried compiling mapserver without GDAL support. When i did that postgis started throwing me similar errors about libxslt, libpam and libreadline Not sure. -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/make-cannot-find-libodbc-and-libodbcinst-on-compilation-tp5962776p5965117.html Sent from the Mapserver - User mailing list archive at Nabble.com. ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users

Like I said, Plan B would be to render a line layer and then a no-outline fill layer; but the performance hit would obviate the advantage of GD. Hi Gregor, A while back someone, maybe Thomas Bonfort, did some performance tests comparing GD to AGG, and if I recall AGG was only slightly slower and in at least a couple of cases it was faster the GD. That said, I can't find the posts I was think of. And this very limited test of one single image: http://www.perrygeo.net/wordpress/?p=77 Implies the GD is about 2x the speed of AGG. More here if you care to look: http://www.google.com/#q=mapserver+performance+gd+agg Also I should point out that the GD renderer is getting removed in 6.0 as part of the rendering pipeline refactoring, unless that plan has changed.

A while back someone, maybe Thomas Bonfort, did some performance tests comparing GD to AGG, and if I recall AGG was only slightly slower and in at least a couple of cases it was faster the GD. In our case, GD renders in 1 second and AGG in 3 in these few tests cases we're concerned with. We're thus allowing a choice between fast mode and good quality mode Also I should point out that the GD renderer is getting removed So I'm not sure there is much interest in chasing issue Well, that's good to know.
