[GIS] Using GeoJSON as an input for GeoServer

apigeojsongeoserver

I have an ArcGIS Online API that I would like to use as an input/store in my GeoServer so that I can publish a service from GeoServer. The format available thorough the API is GeoJSON. I can see that there is an option of adding a WFS as a vector data source but the service I have does not have any WFS or WMS capabilities on and has only GeoJSON output format.

At present, probably no. While GeoTools does have a GeoJSON datastore that could be added to GeoServer it is currently unsupported, has no documentation and lacks the GeoServer wrapper that would provide you with a GUI element to allow you to set it up easily.

You can give it a try by adding the gt-geojsonstore jar file (and dependencies) to the WEB-INF/lib directory but I really don't know what would happen.

You could seek commercial support to finish up the work on the module and integrate it into GeoServer, or provide the needed code yourself.

Or you could prevail on the service provider to use an open standard (like WFS) to publish the data rather than a vendor encumbered one.

[GIS] Getting JSON/JSONP/GeoJSON from GetFeature WFS request to ArcGIS for Server

It is unclear from the question whether you are asking about the possibility of editing an ArcGIS service so that you can provide JSON, JSONP, or GeoJSON as part of a WFS service that you own, or are asking from the point of a user wishing to consume a WFS service.

Looking at it from the a user perspective:

In any OGC Web service, be it WMS, WFS, WCS etc, you can only request formats that are available (advertised) in a service through its GetCapabilities request response. So in the above example, if only GML 3.1.1 is advertised, you can only make request for that format.

It should be noted that just because a piece of software might be capable of delivering a format, if the service provider decides to block that format they may choose to do so.

[GIS] Ol3, dynamic CQL for WFS layer (GeoJSON) from Geoserver

Since this has not been answered. Here is my own solution which is very simple and works well.

The "update" function clears the vector source. The "loader" function, which has been added to the vector source, will then automatically update the features using the url.

var vectorSource = new ol.source.Vector({
    loader: function (extent, resolution, projection) {

    var url = "http://localhost:8081/geoserver/reporter/ows?service=WFS&version=1.0.0&request=GetFeature&typeName=reporter:gtest&CQL_FILTER="+municipalityselector.value+"&maxFeatures=50&outputFormat=application%2Fjson";
    $.ajax(url).then(function (response) {
        var features = geojsonFormat.readFeatures(response, {
            featureProjection: projection
        });
        vectorSource.addFeatures(features);
    });     
    }
});

function update() {
  vectorSource.clear(true);
};

<body>...

<select id="municipalityselector" onchange=update()>
<option value="name='Lund'">Lund</option>
<option value="name='Hej'">Hej</option>
<option value="name='Stockholm'">Stockholm</option>
</select>
