[GeoNode-users] Recommendations Needed

[Cristiano Giovando]

Hi Amanda,

Welcome to the community and thanks for sharing your challenges with
running GeoNode in a low bandwidth environment. I often work with very
similar scenarios and despite not having a definitive answer, these are
some mechanisms that we use to mitigate issues:

- Optimization of data for upload, using compression for smaller transfers
- Clip&ship function for downloading smaller subsets (e.g.
http://haitidata.org/layers/geonode:ht_beaumont_uav_8oct16_rgb_res3cm)
- Add link to download "original dataset" to avoid long transfer
interactions via standard OWS
- Use of new map viewer (MapStore) that optimizes pagination of many layers
from catalog requests
- Simple theme customization and use of web-optimized graphics/images for
the homepage
- Set up of a "portable" GeoNode on light hardware (e.g. Intel NUC) for
offline environments, serving over LAN

We are currently also investigating improvements on the general UI, to
optimize and compress necessary libraries, but this may take some time and
code refactoring. There are also ideas to develop asynchronous
download/upload functionalities (e.g. through Dropbox like integrations)
which would help for data transfers over unstable connections.

Hope this helps!
Cheers,
Cristiano
