Ideas for processing service

[J-Christophe]

Hi all,

I need use cases for processing services. The general constraints are the following :

• the processing service will be host on the scientifique laboratory. We will provide a docker that implements the web service and we will help to integrate the scientific code in the web service
• one of the inputs of the processing service must be based on information available in the PDSSP catalog. The PDSSP catalog will host (soon) the georeferenced PDS data from Mercury, Venus, Mars and Moon.

The use case (for the intefaces) will be the following (or closed to):

1. the user selects information via the PDSSP portal (using snapplanet)
2. the user selects one of the available processing services registered with PDSSP
3. snappplanet send the information to the processing service
4. the processing service receive the informations and downloads the data on its own resources.
5. the processing is performed
6. the result is available in a service
7. According to the type of the data, the result can be displayed on the map on snapplanet or displayed as a link.
8. The user can choose to make available this new product in the PDSSP catalog.

@fredericschmidt , @seignovert @dcordiercnrs ideas are welcome. The aim is to demonstrate the workflow. So if you have a cool ideal and simple, this is great

Thanks

Good idea, but this may be difficult on depending on how "photo realistic" do you want. At least a shaded DTM would be great.

[fredericschmidt]

The original message was something like :

• difficult to have services. Today only crater detection
• maybe a service creating a realistic simulation of a location, depending on local time

[seignovert]

Original message (deleted):
@J-Christophe good idea but it might be a bit too ambitious at this stage.
Except crater counting maybe, I don't really know any if there is many planetary web services at the moment.

One idea I could suggest could be a DTM photo realistic rendering service that pull a region of interest, the user provide a date and time and the service pull the illumination condition to render the scene at that specific date and time. The end results could then be sent back to the index catalog as a new product.

A second idea would be to have a small web-app that can pull hyperspectral images and with a GUI generate custom RGB image. It should support, original image geometry as well as projected data on the ground. The user should be able to manually selected the channels/bands/wavelength of interest, use a mathematical formula or known hyperspectral criteria.
The end result could then be shared back in a new PDSSP catalog.

This would be very useful to generate custom thumbnails on a given catalog (eg. VIMS, OMEGA…)

I really would like to see all the data in a SIG software such ArcGIS and QGIS. This is a really important "science case" by itself.

[J-Christophe]

You will see it Frederic but I need a processing service now. And you will be able to see this processing service in an external software if this external software implements the OGC protocol.

Avoir toutes les publications associées à une zone (on en avait déjà parlé en ajoutant dans le DOI)

• il faudrait lire les ID des données utilisées automatiquement dans le pdf ou les médadonnées
• associer les footprints à la publi
• gérer la base de donnée des publis

[fredericschmidt]

Après, nous on a des projets de service mais c'est plus spécifique à nos activités:

• simulation de spectres VIS/NIR à la volée (linéaire/transfert radiatif)
• inversion d'un spectre observé avec mélange linéaire (abondance)
• inversion d'un spectre observé avec modèle de transfert radiatif pour estimer les paramètres (abondance, rugosité, taille de grainetc..)

[fredericschmidt]

Créer Datacube fusionnant des données hyperspectrales à la volée mais ça c'est déjà en cours... A voir si ça fonctionne bien !

[fredericschmidt]

Etude spectro-photométrique par exemple sur Europe ou la Lune

• récupérer tous les pixels (et pas seulement les images) de toutes les images sur une zone particulière ainsi que les géométries d'observations

[fredericschmidt]

Simulation d'image hyperspectral HypSIM mais à voir avec Sylvain. Je me demande si c'est bien raisonnable de le proposer en tant que service. Je pense que c'est mieux de le partager sous forme un code / éventuellement à mettre dans un jupiter

[fredericschmidt]

Visualisation multi-modale : temporelle, multi-angulaire, multi-longueur d'onde.
C'est déjà en cours mais à voir comment on peut le généraliser pour un corps entier par exemple...
