Project Overview


Scope & Objectives

Part of the European Space Agency Data User Element (DUE)

EO-based Inforamtion Services: Ground Deformations Surface Thermal Anomalies Volcanic Gas (SO2) emissions Volcanic Ash tracking

Main Purpose: “to define, implement and validate a volcanologic information system to support the volcanic observatories, civil protection agencies and the broader scientific community of volcanoes with validated EO products”.

Based on requirements provided by INGV-OV and a worldwide selection of volcanic observatories.


Project Planning GlobVolcano Project has been kicked-off in February 2007

Phase 1 (Completed in June 2008)

Requirement Engineering : Requirements, Design Justification, Technical specification, Service case description.

Design Engineering : set up of the GV Information system, Prototype Products generation, Preliminary Validation and assessment , GV metadata catalogue, QAR.

Promotion, User Federation.

Phase 2 (Started in November 2008)

Service provision, products delivery and GV metadata catalogue update. GlobVolcano products evaluation. Promotion, User Federation.

GlobVolcano Data Processing System (1/3)

Deformation Mapping Service: Two different processing approaches are adopted in order to provide both global and detailed monitoring of the area of interest (Both processing approaches exploit Envisat ASAR data)

EarthView® Conventional DInSAR Technique (MDA Canada)

Alert level increase: temporal resolution of products can be increased by exploiting capability of ASAR sensor to image an area with different geometry

Fast deformation: it can supply users with interferograms providing useful information at least for a first qualitative analysis

PSINSARTM Permanent Scatterers (T.R.E. Italy)

High accurate deformation estimation (APS estimation and removal) for a set radar targets exhibiting a coherence level constant in time

Monitoring of the temporal evolution of the deformation over long time period


Two software tools are adopted for the implementation of the service:

MyVOL for high resolution multispectral EO data (IES Consulting) MyMOD for low-spatial resolution/high-temporal resolution multispectral EO data

(IES Consulting)

GlobVolcano Data Processing System (2/3)

Surface Thermal Anomalies Service Systematic Synergetic Merge of :

High spatial resolution satellite data acquired over long revisit intervals by ASTER (onboard TERRA) and HRVIR or HRGT (onboard SPOT-4 and -5).

Low spatial resolution satellite data acquired with daily frequency by MODIS (onboard TERRA and AQUA).

The combined use of these instruments allows increasing frequency of observation and level of detail


GlobVolcano Data Processing System (3/3) Volcanic Gas Emission (SO2) Service is provided by a link to GSE-PROMOTE-(SACS)

Purpose: deliver Near-Real-Time EO-base SO2 measurements related to volcanic eruptions useful to assess possible impacts of volcanic eruptions on public safety

The service is focused on the delivery of SO2 data derived from different satellite instruments:

Envisat SCIAMACHY (BIRA IASB Belgium) AURA OMI (KNMI The Netherlands) MetOp-A GOME-2 (DLR Germany)

Volcanic Ash Tracking Service is provided by a link to GSE-PROMOTE-(SACS)

Purpose: track the ash injected into the atmosphere during a volcanic eruption.

The service is accomplished by using a proper RGB composite with BTD (Brightness Temperature Differences) relative to SEVIRI-MSG Infrared channels: IR8.7, IR10.8 and IR12.0 (CGS - Italy)


GlobVolcano Information Service

The GlobVolcano Information Service is the product provision infrastructure of the GlobVolcano Information System

The GlobVolcano Information Service includes the following elements

GlobVolcano Products Archives

Functionalities: Web Map Service (WMS), product delivery / downloading

GlobVolcano Metadata Catalogue

Functionality: Catalogue Service for Web (CS-W)

GlobVolcano User Interface (GVUI)

Front end for the users, Based on Virtual Earth platform


GlobVolcano User Interface

Two different points of access can be distinguished:

Public User Interface Not Authorised Users

Private User Interface Authorised Users (GlobVolcano Users)


GVUI – Public User Interface

Geographic area selection

Metadata search


GVUI – Public User Interface

Geographic area visualization

Metadata visualization


GVUI – Private User Interface User Login

Products search


GVUI – Private User Interface

Products selection and visualization

Products selection and delivery / download


GVUI offers the basic Virtual Erath functionalities:

zooming

base layer selection (satellite aerial image, road map or both)

2D and 3D view

oblique aerial view (bird’s eye view is available only for limited location, mostly urban)
