gxp.plugins.ArcRestSource¶

Example Use¶

The configuration in the sources property of the gxp.Viewer is straightforward:

defaultSourceType: "gxp_arcrestsource",
sources: {
    "arcgisrest": {
        url: "http://cga6.cga.harvard.edu/arcgis/rest/services/darmc/roman/MapServer"
    }
}

A typical configuration for a layer from this source (in the layers array of the viewer’s map config option would look like this:

{
    source: "arcgisrest",
    name: "Routes",
    layerid: "show:74"
}
