Dear Pattara,

1. Importing of GeoPackage files seems not supported yet. Is it just not

I confirm that importing a GeoPackage is not currently supported neither
in GeoNode nor in the Geoserver Importer extension, which is employed by
GeoNode for the ingestion of new datasets (so I guess that this isn't
available in Cartoview too).
The implementation would be quite challenging but, as usual, it's doable if
sufficient funds are available.

Currently, GeoNode doesn't provide analysis tools. You can create
dashboards and add widgets (charts, tables, etc.) to a map but only as
visualization tools.
GeoNode uses the OGC services provided by its cartographic backend, which
is Geoserver.

Potentially you could leverage the WFS service and implement your tools in
a custom client app (either as a MapStore plugin or a standalone custom
view published as a custom Django view), using a library like Turf.js
With the help of GeoNode APIs, you could publish the results back as a new
dataset, or alter the original dataset via WFS-T.

>> * add/edit Catalog layer service
As already mentioned by others, we disabled this functionality on purpose,
since maps configurations are stored and managed as GeoNode maps.
A map export might be useful if map layers are public, otherwise, you lose
the authentication and authorization services provided by GeoNode.
A map import would work, but you would end up publishing a map with layers
completely disconnected from GeoNode.

Anyway, if you wish to have these plugins in a custom GeoNode client build
of yourself you might give a look at the development documentation for the

Printing is provided by a Geoserver extension. Basic support to print
custom elements is provided by Vector layer params
This is what for example MapStore uses to print map annotations.
