Hi, I had a try and this with units='meters' http://hip.latuviitta.org/cgi-bin/mapserver_wfs?SERVICE=WFS&VERSION=1.0.0&REQUEST=getfeature&TYPENAME=lv:mml_railway&SRSNAME=EPSG:3067&Filter=%3CFilter%3E%3CDWithin%3E%3CPropertyName%3Ethe_geom%3C/PropertyName%3E%3Cgml:Point%3E%3Cgml:coordinates%3E246700,6780800%3C/gml:coordinates%3E%3C/gml:Point%3E%3CDistance%20units=%27meters%27%3E4000%3C/Distance%3E%3C/DWithin%3E%3C/Filter%3E&MAXFEATURES=300
seem to give the same result as this one with units='degrees' http://hip.latuviitta.org/cgi-bin/mapserver_wfs?SERVICE=WFS&VERSION=1.0.0&REQUEST=getfeature&TYPENAME=lv:mml_railway&SRSNAME=EPSG:3067&Filter=%3CFilter%3E%3CDWithin%3E%3CPropertyName%3Ethe_geom%3C/PropertyName%3E%3Cgml:Point%3E%3Cgml:coordinates%3E246700,6780800%3C/gml:coordinates%3E%3C/gml:Point%3E%3CDistance%20units=%27meters%27%3E4000%3C/Distance%3E%3C/DWithin%3E%3C/Filter%3E&MAXFEATURES=300 The first one sent for TinyOWS does not give results at all but just an error message http://hip.latuviitta.org/cgi-bin/tinyows?SERVICE=WFS&VERSION=1.0.0&REQUEST=getfeature&TYPENAME=lv:mml_railway&SRSNAME=EPSG:3067&Filter=%3CFilter%3E%3CDWithin%3E%3CPropertyName%3Ethe_geom%3C/PropertyName%3E%3Cgml:Point%3E%3Cgml:coordinates%3E246700,6780800%3C/gml:coordinates%3E%3C/gml:Point%3E%3CDistance%20units=%27meters%27%3E4000%3C/Distance%3E%3C/DWithin%3E%3C/Filter%3E&MAXFEATURES=300 The error is about namespaces but Mapserver does not care about such things, which means that Mapserver users learn to write filters which do not work with almost any other WFS server. <ows:ExceptionReport xsi:schemaLocation= "http://www.opengis.net/ows http://schemas.opengis.net/ows/1.0.0/owsExceptionReport.xsd"; version="1.1.0" language="en"> <ows:Exception exceptionCode="InvalidParameterValue" locator="FILTER"> <ows:ExceptionText>Filter Element contains incoherent XML Namespaces </ows:ExceptionText> </ows:Exception> </ows:ExceptionReport> Isn't it fun with WFS? -Jukka Rahkonen- Lähettäjä: [email protected] [mailto:[email protected]] Puolesta Rahkonen Jukka Lähetetty: 24. syyskuuta 2013 16:51 Vastaanottaja: '[email protected]' Aihe: Re: [mapserver-users] Submitting filter does not filter - returns all features Hi, Just a guess, but using units in filters is often poorly implemented. Have a try without units and by giving the distance in degrees. -Jukka Rahkonen- Lähettäjä: [email protected]<mailto:[email protected]> [mailto:[email protected]] Puolesta Troy Day Lähetetty: 24. syyskuuta 2013 16:23 Vastaanottaja: [email protected]<mailto:[email protected]> Aihe: Re: [mapserver-users] Submitting filter does not filter - returns all features I'm looking for advice on how to pass a GET request Filter through mapserver to an oracle spatial database connection. Although I have successfully implemented a BBOX filter, both DWithin and Intersects spatial filters seem to be ignored during the query process because all features (up to MAXFEATURES) are returned. No errors are returned with debug set to 5. Here is a sample URL: http://wfsd.visualapms.com/wfs.php?SERVICE=WFS&VERSION=1.1.0&REQUEST=getfeature&TYPENAME=parcels&SRSNAME=EPSG:4269&OUTPUTFORMAT=json&Filter=%3CFilter%3E%3CDWithin%3E%3CPropertyName%3ESHAPE%3C/PropertyName%3E%3Cgml:Point%3E%3Cgml:coordinates%3E-101.9378217465,36.758602636999996%3C/gml:coordinates%3E%3C/gml:Point%3E%3CDistance%20units=%27meters%27%3E200%3C/Distance%3E%3C/DWithin%3E%3C/Filter%3E&MAXFEATURES=300 Here is the filter part of that url in xml format: &Filter=<Filter><DWithin><PropertyName>SHAPE</PropertyName><gml:Point><gml:coordinates>-101.9378217465,36.758602636999996<gml:coordinates></gml:Point><Distance units="meters">200</Distance></DWithin></Filter> ...and here is the layer definition within the map file I'm using: LAYER NAME "parcels" METADATA "wfs_title" "Parcels" "wfs_srs" "EPSG:4269" "gml_include_items" "all" "gml_featureid" "OBJECTID" "wfs_enable_request" "*" "wfs_getfeature_formatlist" "gml,json,geojson" "gml_COUNTRY_ID_type" "Character" "gml_STATE_ID_type" "Character" "gml_COUNTY_ID_type" "Character" "gml_PARCEL_ID_type" "Character" END TYPE POLYGON STATUS ON EXTENT -180 -90 180 90 CONNECTIONTYPE oraclespatial CONNECTION "SDE/3nz0rb4rr4g1n@ArcSDE" DATA "SHAPE FROM (select OBJECTID, COUNTRY_ID, STATE_ID, COUNTY_ID, PARCEL_ID, APP_USER_G, SHAPE from PARCEL) USING FILTER" PROJECTION "init=epsg:4269" END CLASS NAME "Parcels" STYLE COLOR 240 240 240 OUTLINECOLOR 0 0 0 END END END Hoping others have gone down this rabbit hole...thanks for looking!
