[mapserver-users] RE: SOS Configuration

2012-01-17 Thread Florence.Tan

Didn't see my email get thru.  Appologise if this appear to be a duplicate post.

 Hi List,

I am new to the list and have been trying to setup MapServer's SOS Server to 
serve some observation data.  I have created a map file and managed to have 
GetCapabilities working.  But when trying out the GetObservation, I am 
confused...  not much helpful documentation around and have found this 
discussion from the old SOS User forum : 
http://osgeo-org.1803224.n2.nabble.com/SOS-disconnect-td1992064.html.  However, 
still confused on how to map a database column to SOS output !?!?


Metadata for the layer in my map file :

 METADATA
 "sos_value_alias"  "value_test"  ## value is the name of the db clumn
 "sos_value_componenturl" "http://test.org#value_test";
 "sos_procedure"   "unknown"
 "sos_offering_id"  "waterstorage"
 "sos_offering_description" "value_test"
 "sos_observedproperty_id" "9"
 "sos_describesensor_url" "http://localhost/TEST123.xml";
 "sos_srs"   "init=epsg:4283"
 "sos_offering_timeextent" "1900/2010"


The database connection is successful and the GetCapabilities return the 
following sos information :

-

My quesions are :

"sos_dbColumn_alias" for each column ?
2) What's the purpose of "sos_dbColumn_componenturl" ?  Do I need to create 
this for each dbColumn ?
3) I have map the  "sos_offering_description" "value_test", why does the 
getCapabilities and getObservation return "value_test" as a constant rather 
then retrieving data from the database ?


Appreciave if someone could point out what is the problem of the map file or 
point me to some useful documentation or tutorial on set up SOS in MapServer.

[mapserver-users] Help needed with South pole projection issues

2012-01-17 Thread Fuchs Juan Carlos

Hi folks!

Please, is there someone, so kind to help me to translate this *.prj to
somewhat  (WKT?)

i could pass to Mapserver (projection) to get both maps, one over the
other??

 

this is my *.prj from the base-layer, so to say.

 

PROJCS["Transverse
Mercator",GEOGCS["GCS_WGS_1984",DATUM["D_WGS_1984",SPHEROID["WGS_1984",63781
37.0,298.257223563]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.017453292519943
3]],PROJECTION["Transverse_Mercator"],PARAMETER["False_Easting",350.0],P
ARAMETER["False_Northing",0.0],PARAMETER["Central_Meridian",-66.0],PARAMETER
["Scale_Factor",1.0],PARAMETER["Latitude_Of_Origin",-90.0],UNIT["Meter",1.0]
]

 

this is the snippet in WKT from my *.map file (Projection of the base-map)

 

PROJECTION

  "proj=tmerc"

  "lat_0=-90"

  "lon_0=-66"

  "k=1"

  "x_0=350"

  "y_0=0"

  "ellps=WGS84"

  "datum=WGS84"

  "units=m"

END

 

 

This is the *.prj from the shp i have, and need to get along with the other
one.

 

PROJCS["lambert",GEOGCS["GCS_WGS_1984",DATUM["D_WGS_1984",SPHEROID["WGS_1984
",6378137.0,298.257223563]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.01745329
25199433]],PROJECTION["Lambert_Azimuthal_Equal_Area"],PARAMETER["False_Easti
ng",1000.0],PARAMETER["False_Northing",6391246.5],PARAMETER["Central_Mer
idian",-60.0],PARAMETER["Latitude_Of_Origin",-40.0],UNIT["Meter",1.0]]

 

that is my best try so far,: WKT from my *.map file layer (Projection)

 

PROJECTION

"proj=laea"

"ellps=WGS84"

"lat_1=-40"

"lon_0=-60"

"south"

END

 

what can i say? it displays VERY ugly...

 

Thanks in advanced for any help/advice you can give me.

Re: [mapserver-users] Re: Clustering and tile clipping

2012-01-17 Thread Wim Vanbelle

Unfortunately it didn't solve the problem. I tried a lot of different
values though.

On top of that I'm also getting a lot of

[Tue Jan 17 08:50:08 2012] [warn] [client] mod_fcgid: read data timeout in
40 seconds
[Tue Jan 17 08:50:08 2012] [error] [client] Premature end of script

40 seconds
[Tue Jan 17 08:50:48 2012] [error] [] Premature end of script headers:
mapserv.fcgi
In msCleanupOnSignal.

Anyone have a clue how to increase the timeout? I'm clustering 44K points.
And at lower zoomlevel (values) it is taking a long time.

 Hi,

 I'm very happy that mapserver is now capable of server side clustering.
 However I wonder if it's possible to completely get rid of the tile
 clipping.

 Currently I've clustered a point layer with 44k points:

 CLUSTER
 MAXDISTANCE 100
 REGION "ellipse"

 END

 It is displayed with a simple image:
STYLE
 SYMBOL  "small_shaded.png"
 SIZE21
 OUTLINECOLOR0 0 0
 END

 However, when viewing this on google maps, the images are often clipped
 at the tile edges.

 I figured that I could solve this with mapcache:

 ld
 disk
 g2
 PNG
 2 2
 30
 3600
 2592000

 i've tried higher values for metatile and it helps a bit, but the
 problem simply shifts location. Also with higher values (eg 5 5 metatile)
 mapserver doesn't return the tiles on time for mapcache and I get gaps in
 my results.

 Would preseeding the data help with the timeouts? Any other solutions
 that I may try? The metadata parameter for tile_edge buffer only works with
 labels as far as i know.

 Thanks in advance, this issue has been troubling me for some time now
 :).

 Best regards,
 Wim
