[Geoserver-users] CQL filter WITHIN: format of POLYGON representation

GeoServer GeoServer User
1

Hello!

I am new to using Geoserver and it’s CQL filterand have one question.

When using spatial filters like this on examples: DISJOINT(the_geom, POLYGON((-90 40, -90 45, -60 45, -60 40, -90 40))) is it possible to use different representation of POLYGON part, not in WKT.

My OpenLayers3 map return coordinates of polygons like this : 576672.21, 6540257.09, 577359.71, 6542209.21, 577989.29, 6542495.86, 579026.17, 6541711.21, 580419.39, 6543269.1, 580664.17, 6544099.43, 580614.18, 6544955.09, 580758.17, 6545791.38, 580813.78, 6547493.59, 580882.3, 6547787.52, 580811.63, 6548021.38, 580393.4, 6548714.35, 579647.81, 6549517.7, 579875.04, 6549978.3, 580612.03, 6550602.42, 581146.45, 6551166.54, 582119.77, 6550856.96, 582810.92, 6550037.72, 582907.41, 6549233.2, 583739.4, 6548619.18, 584351.43, 6550480.94, 584724.81, 6551373.5, 585079.15, 6551780.8, 585214.53, 6552210.45, 584823.45, 6552596.57, 583550.39, 6553106.82, 582713.1, 6553609.79, 582769.21, 6554368.62, 583547.58, 6555687.69 and so on.

Is it possible to use them like this?

Tried this, but with no success.
http://loom-gis.geo.ut.ee:8080/geoserver/ermas/ows?service=WFS&version=1.0.0&request=GetFeature&typeName=ermas:testdata_geopnt&outputFormat=text/javascript&format_options=callback:loadFeatures&maxFeatures=300&srsname=EPSG:3301&EPSG:3301&cql_filter=within%28geometry,POLYGON%28%28556500,%206445500,%20637750,%206470250%29%29%29

And what would be geoserver behavior if my polygon contains around 700 points like that I mentioned.

Thanks for any help!

No, WKT is the only supported syntax for any geometry literal in CQL

Hi,
Look at http://openlayers.org/en/v3.0.0/apidoc/ol.format.WKT.html#writeGeometry to get the WKT for your feature.
In OL2 you could just write feature.geometry.toString() and you would get the WKT. Not sure if that works now.

Hi again,
Forgot to answer one of your questions.

I bet GeoServer wouldn’t have any problem with 700 points.
But I bet the browser would. Given that your coordinates have 9-10 chars and you have 700 points that would render about 140000 characters, right?
Browsers doesn’t allow unlimited length on URL:s. See http://stackoverflow.com/questions/417142/what-is-the-maximum-length-of-a-url-in-different-browsers
I normally use the 2048 limit as stated in that link.
I have a case where an application creates several hundreds of id:s to filter. Given that they aren’t connected to eachother I can separate these in separate layers in OL.
But that does not work with a polygon…

Try to use the WFS format to create a GetFeature XML document that you can POST to GeoServer instead of using GET.
http://openlayers.org/en/v3.0.0/apidoc/ol.format.WFS.html#writeGetFeature

Perhaps this question should go on the OpenLayers mailing list.
Or http://stackoverflow.com/questions/tagged/openlayers-3
Or http://gis.stackexchange.com/questions/tagged/openlayers-3

Regards,
Olle Markljung
