[mapserver-users] Color the world, but not my country
Dear,
I have a country shapefile and I would like to style everything, besides
the one feature in the polygon.
This is a shapefile layer, so I'm wondering on how I could possibly improve
this:
LAYER
NAME "gadm"
TYPE POLYGON
TRANSPARENCY 70
DATA "gadm28.shp"
STATUS default
DEBUG 4
CLASS
EXPRESSION ("[ISO]" != "NLD")
style
color "#00"
end
END
END
Basically, I would like to only use the data from the netherlands (NLD),
because it's a lot less data, and color everything else, besides the one
feature that it has.
My above (working example) is taking the entire world and only filtering
out what I want to see.
The goal is to visually create a map of a single country and block out all
the rest ;-). It's rendered as a tile layer. (gmaps)
Thanks in advance for your feedback.
Best regards,
Wim

Re: [mapserver-users] Color the world, but not my country
I came across this, but I'm not quite sure to what other layer it should
relate? I would only have the 'Netherlands' description of the borders.
I do not want to use the world dataset file, because it's too big. I cannot
just add a 'complement' to the country layer or am I misinterpreting the
mask function?
It would be solved I believe if I could add a LAYER which did not require a
datasource and renders everything black, but that is not possible I
believe, because mapserver always requires a type and the annotation type
is deprecated since 6.2
Thanks in advance.

[mapserver-users] Dynamic map data input for mapserver
Hi, When using routeplanners, you often get very detailed results of routes, especially long ones, that need to be drawn by the client. We are considering the option of using mapserver to render these results as tiles. What would be the best way to implement a thing like this? I was thinking of generating some kind of WFS output that is used as input for mapserver, but i'm not sure if it will be dynamic enough. Or, can I for instance make a WMS request that actually specifies the whole Linestring/polyline that needs to be drawn by mapserver? Thanks for your insight. ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
[mapserver-users] Vectorizing/digitizing points that have been rendered as raster
Hi, Currently we have a lot of big datasets with points (think 50k points for instance) that we can now cluster service side with mapserver (cool). That works like a charm, but now we would like to fetch information if you click on them. (be it a clustered icon, or a non clustered). The client we are using is google maps with custom javascript code. As far as I'm aware, I need to perform a WFS request for this. I haven't got any problems setting that up, but what should be passed as a filter? Can we just pass a point as a filter in the request, or are we forced to supply a bounding box. I'm wondering if there are common solutions to tackle a similar problem. Thanks in advance.

Re: [mapserver-users] mapserver defunct
The problem definately seems related to concurrency. Load benching using 1 concurrent requests: 0 fails. Load benching using 2 concurrent requests: +- 30% fails more concurrent = more fails. The failed seem to return with HTTP 500. Running a shp2img during this time, still returns a good image. I'll post more info about this topic and a resolution, if i find one :). Do note that we're dealing with shapefiles with 3 000 000 linestrings. While they consist only of 2 coordinates (begin end obviously), it's still a big thing to load.

So since you are running fastcgi, it is the responsibility of the fastcgi parent process to clean up dead child processes. It is likely that it is busy because you are doing load testing or there is some subtle issue that is occurring. If you are getting good responses from mapserver, you probably do not need to worry about it unless you are getting tons of them. If you are using apache, I believe there is a parameter that you can set for fastcgi processes which will let them die after N requests. This should clean those up and apache will spawn a new process if needed to replace the that died. -Steve W On 1/11/2011 10:04 AM, Wim Vanbelle wrote: Hi all, I'm getting a lot of 27098 x 20 0 000 Z1 0.0 0:00.03 mapserv defunct 27104 x 20 0 000 Z1 0.0 0:00.03 mapserv defunct while load testing mapserver.

Re: [mapserver-users] mapserver defunct
Thanks for your comments. I'll try switching to CGI.

Initially we started using postgres, but switched to shapefiles because that would scale better with higher load. (no need to setup more databases) We have a lot of ram available, so any tips on using that better are appreciated. using iostat/vmstat i can see that disk was no issue though. On 12 January 2011 16:52, Stephen Woodbridge wood...@swoodbridge.comwrote: Have you built mapserver with threads? If so disable this and see if the problem goes away. HTTP 500 probably means that your process is getting a SIGV. Also unless you are using a database connection, using fastcgi is not going to give you a huge benefit because of the way mapserver works. And threads will probably not help either. OK, I admit I am somewhat biased against threads :) Tuning for performance in my experience is: 1. start by keep it simple 2. measure where your bottlenecks are 3. fix these bottlenecks 4. repeat Don't throw everything at it because you think think it will help. It just makes a complicated mess and you have no way to know if any given pieces is helping or hurting. Using a tmpfs is good if you manage it, I prefer a ramfs, the difference being the a ramfs is fixed size and you have to explicitly load it, but you have more control over size and behavior for a little more planning and it does not have down side of being able to eat all your memory or forcing linux to do more swapping which can slow down things. Also if you need to squeeze an additional 1-1.5% performance and can live without swap, disable your swap partition. Linux is a swappy OS and swaps to disk before it needs to in anticipation, this is costly if you have a lot of memory and do not NEED to swap. -Steve W On 1/12/2011 7:23 AM, Wim Vanbelle wrote: The problem definately seems related to concurrency.

Re: [mapserver-users] mapserver defunct
Well, the problem is that the requests are not always served. During load testing, say about 10 concurrent requests I also load the map. But there are randomly tiles that are never loaded. I thought this would be related to the defunct processes, but that is not a certainty. My setup is lighttpd + fastcgi. To be honest I'm in a pretty bad situation now, considering we go live with this in 9 days. Not sure what else I can do honestly. On 11 January 2011 19:05, Stephen Woodbridge wood...@swoodbridge.comwrote: Here is an explanation of defunct processes: http://www.webmasterworld.com/forum40/1032.htm I'm sure there are others. So since you are running fastcgi, it is the responsibility of the fastcgi parent process to clean up dead child processes. It is likely that it is busy because you are doing load testing or there is some subtle issue that is occurring. If you are getting good responses from mapserver, you probably do not need to worry about it unless you are getting tons of them. If you are using apache, I believe there is a parameter that you can set for fastcgi processes which will let them die after N requests. This should clean those up and apache will spawn a new process if needed to replace the that died. -Steve W On 1/11/2011 10:04 AM, Wim Vanbelle wrote: Hi all, I'm getting a lot of 27098 x 20 0 000 Z1 0.0 0:00.03 mapserv defunct 27104 x 20 0 000 Z1 0.0 0:00.03 mapserv defunct while load testing mapserver.

Re: [mapserver-users] conf of MapServ+Apache.Lighttpd for better usability
This would be a good thing. That way, if you would zoom in to a location very quickly, you would also not have to wait for mapserver to render the outer zooms first (where you clicked through quite fast), but you would get your data first and the data you don't need anymore later.

There is a situation that makes the use of MapServer not very user friendly: An user A opens a map, activates a slow layer and drags the map around. This would add a lot of calls to the webserver that would launch many MapServer processes reaching the maximum number of processes. At the same time, there is another user B displaying another layer... this time a fast layer As the maximum number of processes has been reached, the webserver cannot create new processes until those alive finish their work, it cannot serve the other user... that is very annoying as The other user would have to wait a long time until the queue is processed and his map is displayed. Another similar situation is when the user A get annoyed as the map is not displaying and therefore decides to turn off the layer and turn on a different layer... say a fast layer... he still need to wait that all the MapServer processes finish the processing... That annoys the users that doesn't understand what is going on... and thinks that the server has crashed... Is there anyway to configure Apache/Lighttpd to give higher priority to the new calls ? (that means to conver the queue from FIFO to LIFO) I have configured Apache FastCgi to kill the old processes once a minute... but the process wont die... actually they would not die with a simple kill... they would die with only kill -9 !!!

Re: [mapserver-users] Polygon hatch mismatch at tile borders.
I mailed this list for an issue regarding lines that have a certain thickness, that get cut off at the tile. Is this related to the same known issue above? So far I've been unable to resolve it using other suggestions. While using openlayers I can effectively use gutter, but that is a client side solution. I'd prefer something at the mapserver level as the client solution wouldn't work on google or bing maps. Steve Lime: this was the problem I reported to you a while ago.

Re: [mapserver-users] Split Polygon using Clint or server side code not with PostGIS
Hmm. No guarantees, but perhaps the geoapi.net or nettopolgysuite have this functionality. Alternatively, what you could do, although it still involves a spatial database, is use the C# Sql Spatial libraries. You could install a microsoft sql server 2008 (spatial) database, reference the spatial libraries and perform the split of the polygon with those spatial functions, using C#. But as you stated, this is probably not the solution you are looking for. Maybe someone else is aware of another third party library that does this :).

Hi, If you compile mapserver from source, you can use ./configure --prefix=/path/to/executable to install it in the folder you want. You do need to make sure that LD can find the shared libraries.

Just configure a CGI script at a given URL (as configured in your webserver) and then point to the location of your mapserv executable.

That would indicate that panning/scrolling behaviour will not be fluent, as you have indicated. We're quite pleased with the current tiling output and performance. Perhaps I will need to write a proxy that translates tiles to actual boundary requests and then add some buffer space there. Or take a look at Paul's reply :). I'll try some things tomorrow if I have the time.

Perhaps there is not much advantage in making tiled requests either. Applications asking for 256x256 pixel sized tiles from on-demand bases are generating rather a lot of load for Mapserver. There is an advantage on the user side because tiles are cached on the client side and panning is fluent. However, the feeling is not necessarily bad even if the client is making single tile WMS requests. With OpenLayers single tile requests used together with transition effect resize is not bad at all. Perhaps Google maps and Bing have some similar modes. Rendering and labeling problems should go away by using single tiles. -Jukka Rahkonen- -Alkuperäinen viesti- Lähettäjä: mapserver-users-boun...@lists.osgeo.org [mailto:mapserver-users-boun...@lists.osgeo.org] Puolesta Stephen Woodbridge Lähetetty: 24. elokuuta 2010 16:43 Vastaanottaja: mapserver-users@lists.osgeo.org Aihe: Re: [mapserver-users] Mapserver tile generation - google maps Tilecache probably is not what you want if you have very dynamic tiles. Or at least a tile cache that is persistent. Your problem is with tile edge artifacts. It might be possible to draw on a slightly larger image than the tile, then cut the tile out of it to avoid some of those, but there are some tile artifacts that you can not get away from when you draw single tiles, like label positioning and label thinning over multiple tiles. For an alternative, you might look to mapscript where you could have more programmatic control over the rendering and do things like render a larger image than needed and cut out the tile like I mentioned. You might also write a bug against mode=tile and see what the developer response to that might be. -Steve W On 8/24/2010 8:04 AM, Wim Vanbelle wrote: For reference sake: The issue is also present when using Bing maps as overlay.

Re: [mapserver-users] Offset values from database
Would it not be possible to draw the polygon as 2 different polygons (the inner polygon the outer using the postgis functions)? You could specify a fixed offset for one or the other. On the other hand, if you just have 1 polygon (with a single line, so no inner polygons) and you're trying to accomplish a visual effect that the inside of the polygon lies further away, i would accomplish this by drawing a thicker border. Or you could possibly use the asymmetric line drawing functions that are available. Maybe give a more concrete example of what exactly you are trying to do.
