[mapserver-users] Disable WMS 1.3.0-Support in MS 5.6.3

[Stephan Holl]

Hello,

ist it possible to disable the support for WMS 1.3.0 with a
configuration switch right now?
It could be handy for some of my usecases.

Curios.

TIA

Beste Grüße

Stephan

[mapserver-users] Re: WMS and tiles cutting off

[kaipi]

Hi,

you can use  http://tilecache.org/ Tilecache   with the option metatiling
enabled. With metatiling enabled Tilecache will fetch larger tiles (eg.
4096x4096) from Mapserver and will cut them into smaller tiles (eg.
256x256). It will also increase performance because Mapserver does not need
to render tiles when they are already in cache.

Hi Stephan,

Not that I know of. It would be possible to add as enhancement a way to 
set/read in the map file the default wms version in case the request url 
does not have a version set. Right now it defaults to the latest 
supported version (1.3.0).


regards,


Curios.

Re: [mapserver-users] Mapscript Rasterquery returns empty result

Hi,

I have the following code:

$oMap->prepareQuery();
$oPoint = ms_newPointObj();
$oPoint->setXY($x,$y);   //coords received from a AJAX call


$oLayer = $oMap->GetLayerByName($szLayer); //Name received from a AJAX call
$status = $oLayer->queryByPoint($oPoint, MS_MULTIPLE, 1);
$status = $oLayer->open();
$result = $oLayer->getResult(0);
$numResults = $oLayer->getNumResults();
$shape = $oLayer->getShape($result->shapeindex,$result->tileindex);
echo(var2json($shape));

This results in the follwing json code to be returned:

|{"_handle_":Resource id #45,"numlines":1,"type":0,"index":-1,

"tileindex":-1,"classindex":0,"numvalues":8,"text":"",

"bounds":{"_handle_":Resource id #46,"minx":607000,

"miny":677000,"maxx":607000,"maxy":677000},

"values":[null,null,null,null,null,null,null,null]}|

No matter what I try, it keeps returning empty shapes. How can this be?


Tom,

I agree with Alexander that you should be carefully reviewing your
input coordinate and insuring it is in the same coordinate system
as the raster file.  The returned values are expected if you are
attempting to fetch a non-existant result shape.

If you simplify your test case down as much as you can and you still
can't figure out why you do not get a result then you could try to
bundle this up and submit it as a ticket.  Keep in mind that such a
ticket is much more likely to be acted on if you make it *easy* for
the developer to reproduce your problem.

Best regards,

Reading the error message, I would try to add parameter SRS  like

&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&LAYERS=Parcelles&SRS=EPSG:27572

But you'll need a few more parameters:

&BBOX=minx,miny,maxx,maxy  <- replace with your values
&WIDTH=300
&Height=200
&FORMAT=image/png
&STYLES=''

Maybe. Can you show the request URL or your layer definition in
OpenLayers? You have to match the layername defined in you map file.

RE: [mapserver-users] Mapscript Rasterquery returns empty result

[Tom van der Putte]

Hi Frank, Alexander,

Thx for the replies. I'll give it a try as soon as possible. I do have a good 
hunch however that it won't come down to the coordinates, because when I try 
his on a tiff, this is the error it gives when clicking on a section of the 
tiff that has any value except noData; when I click on an empty section 
(NoData) it gives a different error. Some testing with this showed that it does 
send and uses the correct coords.

I think it might have something to do with the tiffs themselves. I'll follow 
your advise an create a testcase as simple as possible. Note that I'm using 
5.2.1 and can't easily upgrade to 5.6, so a ticket might not be appropriate?

Cheers, Tom

[mapserver-users] MINSCALEDENOM in layer units

[Paco Regodón]

Hi,

MINSCALEDENOM is specified using map units.

I have a mapfile which can be requested using epsg:4326 (degrees) or 
epsg:25830 (meters) using &map_projection=init=epsg:4236 or 
&map_projection=init=epsg:25830.


The problem is that different scales are computed in both cases. Scale 
varies between 3 and 100 when working with degrees, or between 5000 and 
15.000.000.


One layer need to be represented only at certain ranges, but if i define 
MINSCALEDENOM in degrees, it will fail to represent when using meters 
and viceversa.


Is there any way i can define MINSCALEDENOM in layer's units instead of 
map units? Something like a SCALEUNITS tag at layer level?


Thanks,

Paco Regodón

Re: [mapserver-users] Re: WMS and tiles cutting off

[Adam Eskreis]

I have thought about using tilecache with metatiling, however there is a
caveat about this map that i forgot to mention in my main post, and it has
to do with that "categories" parameter.  Basically, each point/symbol on the
map has an associated category in the database backend.  I am using
mapserver/WMS parameters to change the categories which are called.  Each
time the user selects a category, only the points in that category are
shown.  My query in the mapfile looks something like thi:

SELECT point_geom,gid,symbol,angle FROM mapdata WHERE category
IN(%CATEGORIES%)";

And each time the user changes the categories, I use openlayers to merge new
parameters, and input the new category values that should be used.  Is
tilecache still useable if I have a system like this set up?

Thanks,
-Adam

Mark,

In the short term you can download that tutorial data from:

Unfortunately in the recent website outages, this one drive seems to 
have problems, so this issue is reported in the ticket:

Thanks for catching this!

Re: [mapserver-users] Re: WMS and tiles cutting off

[Adam Eskreis]

Ok, I just gave an untiled layer a try, unfortunately though, due to the
large amount of symbols being displayed on the screen, there is about a 2
second delay every time the map is panned.  My client will most certainly
find this unacceptable.  I have tried using smaller images, but I cannot
sacrifice any more quality.  I believe my database query to be as optimized
as it can be (has about 50 ms runtime, I honestly don't think I can get it
any lower than that).

If these are the only options, is there something else besides WMS that you
all would recommend using to solve this issue?

Thanks,

RE: [mapserver-users] Re: WMS and tiles cutting off

[Lime, Steve D (DNR)]

Note that by default I believe openlayers will request an image that is *much* 
larger than what is visible. Setting the layers (OL) ratio:1 makes it the same 
size as the view port and that can speed up rendering considerably.

Alternatively you could create a separate set of tiles for each category I 
suppose and switch OL layers as necessary...

SELECT point_geom,gid,symbol,angle FROM mapdata WHERE category 
IN(%CATEGORIES%)";

And each time the user changes the categories, I use openlayers to merge new 
parameters, and input the new category values that should be used.  Is 
tilecache still useable if I have a system like this set up?

Thanks,
-Adam

Hi,

you can use  http://tilecache.org/ Tilecache   with the option metatiling
enabled. With metatiling enabled Tilecache will fetch larger tiles (eg.
4096x4096) from Mapserver and will cut them into smaller tiles (eg.
256x256). It will also increase performance because Mapserver does not need
to render tiles when they are already in cache.

RE: [mapserver-users] Re: Fail on generate extension of mapscript for Tcl 8.5

[Lime, Steve D (DNR)]

Hi Tiedtke: There just aren't that many Tk/Tcl users for MapScript. There's one 
big user that apparently has a set of patches to bring Tk/Tcl support
for MapScript inline with the others. I don't know how much they pay attention 
to MapServer-Users though. I'll contact them off list and see if I can
get some love for you question...

Hi folks,

Based in old version of tcl mapscrip for windows in this site:

http://msworkbench.sourceforge.net/

I'm trying to recompile a version of mapscript (5.6.2) tcl extension (based on 
sdk pack of Tamas site, version 1500, windows 32bit).

Some modifications in path of files nmake.opt (root of mapserver src) and 
Makefile.vc in tcl mapscript dir, the files were generated:

mapscript_wrap.c (using swig 1.3.39 and Tcl/Tk 8.5.8, from ActiveState)
mapscript.dll
mapscript.exp
mapscript.lib

But, when i try to load this dll in a Tclsh terminal (load mapscript.dll), a 
strange error is shown, saying this:

couldn't load library "mapscript.dll": A function specified in the import table 
could not be resolved by the system.  Windows is not telling which one, I'm 
sorry.

I put this dll in same places of others dll from Tamas Package ( 
release-1500-dev\release-1500\bin ), and verified the dependencies with 
depends.exe and nothing were pointed.

The two functions were exported (Mapscript_Init and Mapscript_SafeInit) in dll, 
but it don't work 

The files generated are here (rar file): 
http://engemap-ped.dnsalias.org/conv/mapserver-5-6.rar or individual files: 
http://engemap-ped.dnsalias.org/conv/mapserver-5-6


Thanks on advance, for any tips about this...

Re: [mapserver-users] Re: WMS and tiles cutting off

[Adam Eskreis]

I tried doing ratio:1 unfortunately it doesn't seem like enough of a
performance increase.  Separate layers for each category is an option,
however, there are over a hundred categories, and any combination of
categories can be on at any given time, so this could prove to have
performance issues of it's own.  However, I thank you guys Steve and Kaipi
for your advice.  I think I am just going to go back to my old method, which
was using php mapscript to generate the tiles, then each time the user
selected new categories, purge the cache and remake the mapfile.  It's not
the ideal solution but it seems to be the only one.

Thanks again,

-Adam
