Abstract:
Within the EUROFLEETS project, and linked to the EMODNet and Geo-Seas European projects, GLOBE (Global Oceanographic Bathymetry Explorer) is an innovative and generic software.

I. INTRODUCTION

The first version can be used onboard during the survey to get a quick overview of acquired data, or later, to re-process data with accurate environmental data.

II. MAIN FUNCTIONALITIES
The version shown at AGU-2014 will present several key items :
- 3D visualization: DTM multi-layers from EMODNet,

- Water Column echogram, Seismic lines, ...

- Bathymetry Plug-In: manual and automatic data cleaning, integration of EMODNet methodology to
introduce CDI concept, filtering, spline, data gridding, ...

- Backscatter with compensation,

- Tectonic toolset,

- Photo/Video Plug-In

- Navigation 3D including tide correction, MRU corrections, GPS offsets correction,
- WMS/WFS interfaces.

III. FOCUS ON EMODNET 
One of the main objectives of the EMODNet European project is to elaborate a common processing flow for gridding
the bathymetry data and for generating harmonized digital terrain model (DTM) : this flow includes the definition of the
DTM characteristics (geodetic parameters, grid spacing, interpolation and smoothing parameters…) and also the
specifications of a set of layers which enrich the basic depth layer : statistical layers (sounding density, standard
deviation,…) and an innovative data source layer which indicates the source of the soundings and and which is linked
and collects to the associated metadata.

GLOBE Software provides the required tools for applying this methodology and is offered to the project partners.

V. FOCUS ON THE TECTONIC TOOLSET
The tectonic toolset allows the user to associate any DTM to 3D rotation movements. These rotations represent the
movement of tectonic plates along discrete time lines (from 200 million years ago to now). One rotation is described by its
axes, its value angle and its date. GLOBE can display the movement of tectonic plates, represented by a DTM, at
different geological times. The same movements can be operated for geotiff images or GMT files representing grids
for any kind of data.

The free software GLOBE3D is a product of Ifremer and is funded by Carnot-Edrome
