Advanced services

The validated and aggregated buffers of data sets are input for the products and advanced services:

Interpolated maps as produced with DIVA software

Time series graphics for all collected data sets via WPS (Deltares)

OceanBrowser viewer (Ulg) as common service for viewing the DIVA maps and giving access to the time series graphics

Sextant catalogue (Ifremer) to document all products with metadata

From QA/QC observations to dynamic data products

Deltares services

ODV to geodata

From geodata to information servicesby OGC WPS servicesaccording to user specified choices

Step 4

Data model for metadata enriched ODV collections into PostgreSQL/PostGIS database (hosted at CINECA)

Committing ODV data collections to the database

Creation of data model

Reading QA/QC’d files from regional coordinators

Adding vocabularies, EDMO, Local_CDI_ID,

Fill table observed_cindex (does not give values, but a color index based on the range of values and transformed to rgb scale)

Create/Refresh GeoServer for location and intensity map

Spatial distribution by GeoServer layers in OceanBrowser

Circles show data location (within depth and time range)

Circle are semi-transparent (intensity of a color gives an indication of number of observation points)

Plot of data at selected location as Time Series

Clicking on a circle Time series plots

(x-axis: time; y-axis: parameter)

Depth is represented by color

Plot of data at selected location as Profile

One can switch

between time series and profile view

For profiles(x-axis: parameter

and; y-axis: depth) Time is represented

by color
