Web World Wind framework

Gisat awarded at the ESA Conference on Big Data from Space 2016.

Demonstration of innovative ways how to visualize metadata from Sentinel-1 and Sentinel-2 satellites in 4D using open source libraries within the Web World Wind framework were voted Best Demo and Best Poster at the conference.

The 2016 Big Data from Space conference (BiDS’16) was jointly organised by the European Space Agency (ESA), the Joint Research Centre (JRC) of the European Commission and the European Union Satellite Centre (SatCen), in collaboration with the Instituto de Astrofisica de Canarias (IAC). The conference took place at the Auditorio de Tenerife, in Santa Cruz de Tenerife, Spain, from 15 to 17 March 2016.

Web World Wind is an open source framework for displaying the 3D globe and layers and elements on top of this globe. This framework is written in JavaScript and the main contributor is NASA. Within the ESA project “Software Prototyping and Mobile App Development” Gisat participates in the activity aiming at helping NASA Web World Wind developers to add new features to the framework. Gisat is currently developing the support for the KML format.

The demonstration application built using the Web World Wind has been presented at the conference. We aimed at creating tools for transforming the metadata from various ESA data sources and at meaningful visualization of the results. Number and type of products acquired by different ESA EO missions have been selected for the practical demonstration.

In the application, the amount and spatial distribution of ESA products acquired within the defined time series are displayed together with the information about the type of products. To provide a user with an accurate overview of the data status the information is displayed using the 3D globe. The main asset which differentiates this solution from other tools is the adaptation of the choropleth to the currently visible area.

The Software Prototyping and Mobile App Development project is run by an international consortium led by Solenix Deutschland GmbH (DE) with TERRASIGNA Srl (RO), Gisat s.r.o. (CZ), Progressive Systems Srl (IT) and Qualteh JR Srl (RO) as subcontractors.
