import of landslide layers

[stufraser1]

@pgiraud Do pre-processed landslide layers (prefix 'LS-') get harvested by the process currently? We have two layers in geonode that should be pulled into TH!

[pgiraud]

If I remember well, the "Landslide" hazard type was supposed to be added later. Thus we have never set the processing parameters for this hazard type. See https://github.com/GFDRR/thinkhazard/blob/master/thinkhazard_processing.yaml

Can you please tell what values we should use for the different levels? ping @NicolasT-brgm

[stufraser1]

@NicolasT-brgm @pgiraud The raster values are already processed as Very Low, Low, Medium, and High (no value thresholds given). The unit in geonode metadata is Landslide Susceptibility Index. It should be accepted the same way as volcano, if at all possible - I would very much appreciate if it can be included

[pgiraud]

I opened sedac_ls_reclass.tiff file in QGIS. Looks like there are 4 different values (from 0 to 4). No_Data is supposed to be "value=15" but there's no pixel of that value.

Here's the value I set in the settings:

   LS:                     
    hazard_type: landslide
    values:               
     HIG: [4]            
     MED: [3]            
     LOW: [2]            
     VLO: [1]            

Is this correct?

[stufraser1]

correct, thank you

[stufraser1]

So the LS layers show in the admin UI as being uploaded to the tool, but it is currently not possible to select Landslide in the UI, for admin units that have landslide data

[pgiraud]

Did you make sure that you're checking on the preview interface?

[stufraser1]

Now viewing on the preview interface, Landslide shows. It would be great to have this published as soon as possible. Is there a reason at the moment for not publishing it to the public view?

[pgiraud]

The publication of data was meant to be done once everything is ready. ie. when:

• all recommendations are created/updated,
• quality ratings are correctly set in geonode, and taken into account by the tool,
• new hazardset has been added,
• processing settings have be changed and results have been checked.

Since a new archive of the database is created and stored each time we do the publication, it's not meant to be done each time the processing is finished.

However I can publish the data as soon as you want if you want to see/show the results in the public interface. Just tell me.

[stufraser1]

@pgiraud Thanks, I understand reasons for publishing once everything is ready. Could we make an exception in this instance, to enable one of our expert groups to do some sanity checking on the landslide data that is now contained in the tool? Thank you.

[pgiraud]

I'll just wait for @NicolasT-brgm to finish editing the recommendations, then I'll publish the data. This should be possible before lunch time.

[stufraser1]

OK, thanks. In the meantime I've updated the data quality on LS layers

[NicolasT-brgm]

I have finished; I have struggled with formatting, hope I now sticks to original proposals Arnaud can run the processing now Nicolas
