  1. Hello! I'm working in a viewer with openlayers and with geoserver and I want to filter layers by a variable. I'm not going to ask anything about geoserver nor openlayers. My problem is about put variables in a url. To obtain geoserver layers from openlayers you have to call them by a url and to filter them you have to use CQL_FILTER. (Filter to shows only what the user wants). My viewer works fine if I put a simple value to filter: (gid_cuenca_id is a db column) var imbornalesSource = new ol.source.ServerVector({ format: new ol.format.GeoJSON(), loader: function(extent, resolution, projection) { var url = 'http://localhost:8080/geoserver/cia/wfs?service=WFS' + '&version=1.1.0&request=GetFeature&typename=cia:imbornales&PROPERTYNAME=gid_cuenca_id&CQL_FILTER=gid_cuenca_id=1&' + 'outputFormat=text/javascript&format_options=callback:imbornalesloadFeatures' + '&srsname=EPSG:3857'; $.ajax({ url: url, dataType: 'jsonp' }); }, projection: 'EPSG:3857' }); However, if I try to put a variable in the url, I receive an error: Uncaught SyntaxError: Unexpected token <I wanted to know if there is any way to put the variable's value as if it was a simple value. var myVar = 1;var tramosSource = new ol.source.ServerVector({ format: new ol.format.GeoJSON(), loader: function(extent, resolution, projection) { var url = 'http://localhost:8080/geoserver/cia/wfs?service=WFS' + '&version=1.1.0&request=GetFeature&typename=cia:tramos&PROPERTYNAME=gid_cuenca_id&CQL_FILTER=gid_cuenca_id=myVar&' + 'outputFormat=text/javascript&format_options=callback:tramosloadFeatures' + '&srsname=EPSG:3857'; $.ajax({ url: url, dataType: 'jsonp' }); }, projection: 'EPSG:3857' }); Thank you very much!!
  2. Hello, I'm trying to do a search function in my viewer. I would like if anybody have already done this before and if can help me. I want to put a street name (for example) in a searcher and then the viewer visualizes the street. I'm using Openlayers3 with js buttons . Thank you!
  3. Hi folks, I just started working on a very interesting project as part of my university research for 3D visualization of earth's surface in 3D (not 3D modeling but real 3D!) using nVidia 3D vision in browser environment. I'm planning to use one of web-based javascript mapping platforms (like open layers or leafletjs) as a base and develop necessary modules for 3D visualization. I have all necessary data (2 image pairs for a test area created from satellite image and Digital Elevation Model) and looking for information on platform, modules and libraries you might know that can help me build this or even any already developed tool you know. I would also appreciate if you mention any document, resource or guide you can share or if you have any comment, advice or ideas. In case you are interested in being part of this tiny but fun project, you can contact me on the following Email: T E Z a-t A B 0 d-o-t O R G (without space! third character after at sign is "0" (zero) and not "O" (the letter)) PS: here is a demo of nVidia's tech on browser for those who have access to 3D glasses and graphics card (you should choose 3D vision tab in gallery and turn your 3D feature ON to see it): http://photos.3dvisionlive.com/HiTechLegion/image/4d0191b7378501b5010c0000/ Cheers
