[GeoNode-users] Newbie / Evaluating GeoNode

Hello Mike,
GeoNode relies on the GeoSpatial server in order to manage the projections.
Also on the frontend, the client is pluggable.

So, long story short, this is all customizable. By default, GeoNode
provides GeoServer, as geospatial backend, and MapStore2 as gis client,
which uses mercator as default projection.

That said when you upload a new layer, GeoNode checks for a valid
projection file. It tried to keep the native projection on the backend
whenever is possible.

In the case it cannot find it, it asks to the user to specify a valid
native projection for the data.

The available choices must be configured on the GeoNode settings. The
default ones are the following


    'EPSG:4326': '(4326) WGS 84',
    'EPSG:900913': '(900913) Google Maps Global Mercator',
    'EPSG:3857': '(3857) WGS 84 / Pseudo-Mercator',
    'EPSG:3785': '(3785 DEPRECATED) Popular Visualization CRS / Mercator',
    'EPSG:32647': '(32647) WGS 84 / UTM zone 47N',
    'EPSG:32736': '(32736) WGS 84 / UTM zone 36S'}
