Derby Laboratory for Visualization and Spatial Analysis (LVSA)

Overview

The inter-College University research laboratory in the College of Engineering and Technology epitomizes Derby University’s interdisciplinary culture. Digital Earth and Big Earth Data are interdisciplinary and complex areas of study by integrating technology-centred and human-centred approaches from the perspective of information system science. The Lab for Visualization and Spatial Analytics (LVSA) conducts research into:

  • Fundamental research questions, both in theoretical and practical aspects, related to processing (the creation, capture, storage and conversion of Big Earth Data from implicit to explicit), mapping, codifying, extracting, visualization and utilising various forms of Big Earth data in firms and organisations;
  • Developing innovative methods, models and tools for the spatial data analytics, innovation and learning capability to help UK enterprises sustain their core Big Earth data-based competencies and competitiveness advantage in the data economy.

Grants and Projects

LVSA has extensive research experience following their involvement in a large number of funded projects by the EU, ESA, Teaching Company Schemes, Knowledge Transfer Partnership and private companies. The Laboratory’s goals are:

  1. To design and develop computer software for the analysis and graphic display of spatial data;
  2. To distribute the resulting software to governmental agencies, educational organizations and interested professionals; and
  3. To conduct research concerning the definition and analysis of spatial data and process.

While Grid computing has been a prominent technique to tackle computational issues in Big Data, little work has been done on making Grid computing adapted to remote sensing applications. The aim of one of research projects is to develop a collaborative environment “Service-Oriented Remote Sensing Information Service Grid Platform (SORSIS)”. The platform consists of a web portal, a quantitative remote sensing model base and a dynamic quantitative remote sensing processing workflow engine. It will provide one-stop-service for remote sensing applications based on “Grid processing on demand”. In this platform, we intended to demonstrate the usage of Grid computing for quantitative remote sensing retrieval applications. The novel technologies developed for SORSIS are:

  • Based on the high-throughput computing grid, the SORSIS enables a workflow management system for data placement. A novel architecture for the remote sensing Grid workflow is designed. The remote sensing quantitative retrieval Grid workflow is a high-level core component of remote sensing Grid, which is used to support the modelling, reconstruction and implementation of large-scale complex applications of remote sensing science.
  • The accompanying unified data-and-computation-schedule algorithm helps load balancing between and within workflow steps. A workload estimation and task partition algorithm was developed, and it executes a generic remote sensing algorithm in parallel over partitioned datasets, which is embedded in a middleware framework for the SORSIS.
