[mapserver-users] SOS Configuration
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 : - sos:Contents - sos:ObservationOfferingList - sos:ObservationOffering gml:id=waterstorage gml:descriptionvalue_test/gml:description - !-- WARNING: Optional metadata sos_offering_name missing for gml:name -- gml:srsNameEPSG:4326/gml:srsName - !-- WARNING: Optional metadata sos_offering_intendedapplication missing for sos:intendedApplication -- - sos:time - gml:TimePeriod gml:beginPosition1900/gml:beginPosition gml:endPosition2010/gml:endPosition /gml:TimePeriod /sos:time sos:procedure xlink:href=urn:ogc:def:procedure:unknown / - sos:observedProperty - swe:CompositePhenomenon gml:id=9 dimension=7 swe:component xlink:href=urn:ogc:def:property:OGC-SWE:1:feature / swe:component xlink:href=urn:ogc:def:property:OGC-SWE:1:identifier / swe:component xlink:href=urn:ogc:def:property:OGC-SWE:1:ftype / swe:component xlink:href=urn:ogc:def:property:OGC-SWE:1:value_test / swe:component xlink:href=urn:ogc:def:property:OGC-SWE:1:type / swe:component xlink:href=urn:ogc:def:property:OGC-SWE:1:description / swe:component xlink:href=urn:ogc:def:property:OGC-SWE:1:yearofcompletion / /swe:CompositePhenomenon /sos:observedProperty sos:featureOfInterest xlink:href=urn:ogc:def:feature:OGC-SWE:3:transient / sos:responseFormattext/xml; subtype=om/1.0.0/sos:responseFormat sos:resultModelom:Observation/sos:resultModel sos:resultModelom:Measurement/sos:resultModel sos:responseModeinline/sos:responseMode /sos:ObservationOffering /sos:ObservationOfferingList /sos:Contents GetObservation (http://localhost/cgi-bin/mapserv.exe?map=C:/ms4w/apps/sos/sos_test.mapRequest=GetObservationservice=SOSOFFERING=waterstorageobservedproperty=9version=1.0.0responseFormat=text/xml; subtype=om/1.0.0) return the following : ?xml version=1.0 encoding=ISO-8859-1 ? - om:ObservationCollection xmlns:gml=http://www.opengis.net/gml; xmlns:ows=http://www.opengis.net/ows/1.1; xmlns:swe=http://www.opengis.net/swe/1.0.1; xmlns:xlink=http://www.w3.org/1999/xlink; xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance; xmlns:sos=http://www.opengis.net/sos/1.0; xmlns:ms=http://mapserver.gis.umn.edu/mapserver; xmlns:om=http://www.opengis.net/om/1.0; gml:id=waterstorage xsi:schemaLocation=http://www.opengis.net/om/1.0 http://schemas.opengis.net/om/1.0.0/om.xsd http://mapserver.gis.umn.edu/mapserver http://127.0.0.1/cgi-bin/mapserv.exe?map=c:/ms4w/apps/sos/sos_test.mapservice=WFSversion=1.1.0request=DescribeFeatureTypetypename=test_sos_layer; gml:description xmlns:gml=http://www.opengis.net/gml;value_test/gml:description /om:ObservationCollection My quesions are : 1) How do I map a db clumn to a sos output ?? Do i have to create 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.

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

I remember I played around with it in the beginning, but currently it is indeed set to 0. What is an acceptable value for this? Am I to set this to the same value as the maxdistance in the cluster? (Being 100 in my case) Or perhaps this should be set to the size of my image representing the cluster, being 10 pixels?

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: tileset name=ld sourceld/source cachedisk/cache gridg2/grid formatPNG/format metatile2 2/metatile metabuffer30/metabuffer expires3600/expires auto_expire2592000/auto_expire /tileset 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 :).

MapScript and the mapfile parser use the same expression tokenizing routine. What happens if you try single quotes? That is: layerObj.setFilter ( '(point.id = 1)' ) Single quotes don't help. I have discovered that the problem is key (?) word 'point', pokus.id = 1 for example, and other table names work well. As a work around I was able to use true and (point.id = 1).

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