Understanding and Managing Our Oceans: Esri Ocean GIS Forum, 05-07 November 2014

/ Matt Artz

Esri logoSee different ways that ocean and maritime agencies are successfully using geospatial analysis to better understand the ocean’s dynamic environment and make intelligent decisions. The Esri Ocean GIS Forum is your opportunity to explore new GIS technology.

Ocean scientists, hydrographers, and GIS experts will be addressing topics that are particularly relevant to people who work for research institutions, the National Oceanic and Atmospheric Administration, seafood companies, energy providers, local and state governments, port authorities, shipping companies, the US Coast Guard, and the US Navy.

The Esri Ocean GIS Forum is a unique event that offers these activities:

  • A rigorous agenda of session topics presented by GIS users that work in the ocean and maritime industries
  • Best practice presentations by project managers from ocean agencies
  • An ocean science forum to share and exchange ideas
  • ArcGIS and ArcGIS Online technical demonstrations set in an ocean and maritime context
  • Meet-and-greet opportunities for expanding professional networks
  • On-site GIS professionals and domain experts that can answer questions and offer advice
  • An EXPO sponsored by ocean and maritime business consultants and technology providers
  • An app contest for posters and Story Maps
  • Two GIS hands-on workshops
  • Learning Lab

Immerse yourself in all things GIS at the Esri Ocean GIS Forum.

GEOFIM: A WebGIS Application for Integrated Geophysical Modelling in Active Volcanic Regions

“We present GEOFIM (GEOphysical Forward/Inverse Modeling), a WebGIS application for integrated interpretation of multiparametric geophysical observations. It has been developed to jointly interpret scalar and vector magnetic data, gravity data, as well as geodetic data, from GPS, tiltmeter, strainmeter and InSAR observations, recorded in active volcanic areas. GEOFIM gathers a library of analytical solutions, which provides an estimate of the geophysical signals due to perturbations in the thermal and stress state of the volcano. The integrated geophysical modeling can be performed by a simple trial and errors forward modeling or by an inversion procedure based on NSGA-II algorithm. The software capability was tested on the multiparametric data set recorded during the 2008-2009 Etna flank eruption onset. The results encourage to exploit this approach to develop a near-real-time warning system for a quantitative model-based assessment of geophysical observations in areas where different parameters are routinely monitored.”
