PlanetServer@EGU2014

PlanetServer/EarthServer

http://planetserver.eu is the main point of access for the Planetary Service of EarthServer (aka PlanetServer).

Planetary Science data collected so far are approaching the order of magnitude of Earth Observation-like volumes (see our XLDB2013 presentation):

pds

PlanetServer tackle the exploitation of this growing datasets largely through WCPS.

Data volume ingested so far is beyond 2 TB.

Classic & Neo Web Clients

Classic and Neo clients are focused on surface science data, particularly hyperspectral (NASA MRO CRISM).

Classic accessible on http://planetserver.eu/classic (Chrome preferred)

Neo (main server now being upgraded) on http://neotest.planetserver.eu (Chrome preferred)

Data Search

search

 

one can identify and select the desired scenes, e.g.

nili-coverage

nili-zoom

nili-select

Main analytical interface

after selecting the desired CRISM scene, the WCPS-based (Table of contents, graph window, console, toolbars) is available:

nili-crism-1

nili-crism-stable-1png

Direct URL

The CRISM observation FRT00003E12 would then be reachable through the URL: 

Direct access to a certain CRISM observation is possible on Classic, e.g.:

VNIR for Nili Fossae:

http://planetserver.jacobs-university.de/classic/?productid=frt00003e12_07_if166s_TRR3

VNIR, IR channels are accessible from the Table of Contents.

RGB

For example, a classical false colour composite can be created using R =band 234 (2.54 µm) - G = 82 (1,51 µm) – B= 14 (1,09 µm):

R – 2.54 µm –> Band234
G – 1.51 µm –> Band82
B – 1.09 µm–> Band14

paying attention to the fact that the channel tab in the Table of Contents should be on “IR” and not “VNIR”.

Spectra

Spectra can be collected on desired points with the Spectrum button:

spectrum-button

and multiple collections are possible.

spectra-nili

e.g. in the example above:

Purple: a rather featureless dusty spectrum (that can be used as reference for ratios, see http://blog.planetserver.eu/?p=286)

Blue: Fe-Mg rich phyllosilicates (clays) ((1.9 and 2.3 μm bands)

Green: Olivine (wide 1 μm absorption)

Red: Carbonates (2.3 and 2.5 μm bands)

the process can be visualised on: http://www.youtube.com/watch?v=uxSzR90svcQ

MARSIS Web Client

The MARSIS web client is reachable at http://marsis.planetserver.eu (Firefox preferred). It provides access to radar sounding subsurface data from Mars, acquired by the ESA Mars Express MARSIS experiment.

Text-based GUI

marsis-text

results are provided on a new tab

marsis-text-output

 

 

Data and simulation can be observed together and compared:

data-sim

Map GUI

A web map interface (inherited and simplified from Classic/Neo web clients) allows selection of single footprints
