[GeoNode-users] zoom levels in geoexplorer

[Aquila Imaging]

Hello!

I am hoping someone can assist me. Forgive the ignorance of my questions
below. This is not my area of expertise.


I am trying to increase the zoom levels in geoexplorer. From what I have
gathered I need to modify:
https://github.com/GeoNode/geonode/blob/master/geonode/maps/templates/maps/map_geoexplorer.js

Per this:
http://gis.stackexchange.com/questions/91902/geoexplorer-setting-more-custom-zoom-levels
I need to add the following to the "maps/map_geoexplorer.js" file.



this.mapPanel = Ext.ComponentMgr.create(Ext.applyIf({
        xtype: config.xtype || "gx_mappanel",
        map: Ext.applyIf({
            theme: mapConfig.theme || null,
            controls: mapConfig.controls || [
                new OpenLayers.Control.Navigation({
                    zoomWheelOptions: {interval: 250},
                    dragPanOptions: {enableKinetic: true}
                }),
                new OpenLayers.Control.PanPanel(),
                new OpenLayers.Control.ZoomPanel(),
                new OpenLayers.Control.Attribution()
            ],
            maxExtent: mapConfig.maxExtent &&
OpenLayers.Bounds.fromArray(mapConfig.maxExtent),
            restrictedExtent: mapConfig.restrictedExtent &&
OpenLayers.Bounds.fromArray(mapConfig.restrictedExtent),
            numZoomLevels: mapConfig.numZoomLevels || 26
        }, mapConfig),
        center: config.center && new
OpenLayers.LonLat(config.center[0], config.center[1]),
        resolutions: config.resolutions,
        forceInitialExtent: true,
        layers: [new OpenLayers.Layer(null, baseLayerConfig)],
        items: this.mapItems,
        plugins: this.mapPlugins,
        tbar: config.tbar || new Ext.Toolbar({
            hidden: true
        })
    }, config));



Where do I add the following in the file? which line?

Also, do I need to make this change on a fork of geonode and then
install with this mod in place or can I just add

this to my existing installed instance of geonode?

Again I apologise for the ignorance of my questions. Thanks in advance
for any assistance.

Regards,

Justin
