“…It is worth noting that in the realm of geoscientific data, there is a wealth of new sensors and data sources, which lead to large collections of diverse and "dirty" data (inaccurate, incomplete or erroneous data), which only gain relevance by careful integration and fusion with complementary data (Van Zyl et al 2009). …”

Big data has now become a strong focus of global interest that is increasingly attracting the attention of academia, industry, government and other organizations. Big data can be situated in the disciplinary area of traditional geospatial data handling theory and methods. The increasing volume and varying format of collected geospatial big data presents challenges in storing, managing, processing, analyzing, visualizing and verifying the quality of data. This has implications for the quality of decisions made with big data. Consequently, this position paper of the International Society for Photogrammetry and Remote Sensing (ISPRS) Technical Commission II (TC II) revisits the existing geospatial data handling methods and theories to determine if they are still capable of handling emerging geospatial big data. Further, the paper synthesises problems, major issues and challenges with current developments as well as recommending what needs to be developed further in the near future.

“…Comparing with the Internet, the standardized work is necessary for achieving the goal of the Sensor Web. Specifically, those open standards provide mechanisms for collaboration as well as conceptual models and standardized formats for the interchange of data (Zyl et al 2009). In summary, OGC SWE initiative consists of three markup languages and fourservice interface standards as shown in Table 1.…”

Sensor Web has been widely promoted and its application has evolved from original military usages to current ubiquitous civil and commercial applications. Its emergence has become a great strength to facilitate the Digital Earth concept. Although many Sensor Web applications and methods have been proposed to assist disaster management, they are not well suited to the unique features and application requirements of disaster management. Most researches focus on how to use the Sensor Web to monitor a certain phenomenon before a disaster happens and to provide early warning. However, there is a lack of study on the negative effects that a disaster may bring to the Sensor Web. For example, severe weather conditions, damaged infrastructure, and spatial isolation may directly make the Sensor Web out-of-service. Besides, disaster management is a complex subject and its domain knowledge needs to be clarified. In this paper, the domain of the disaster management is explored and its unique features are analyzed. Then the Sensor Web concept and its role in disaster management are explained. Afterwards, the challenges of the Sensor Web for disaster management and the possible solutions are discussed. Based on the above, we introduce a high-mobility emergency system to demonstrate a good solution of the Sensor Web for multipurpose disaster management.

“…In the early 2000s Delin and Jackson (2001) and Delin (2002) have proposed the "sensor Web" that aims at developing a standard integration layer capable to harmonize sensor protocols and interfaces in order to drastically reduce the high and extensive effort of manual bridging between sensor resources and applications. In this context, a series of initiatives like the Global Earth Observing System of Systems (Zyl et al 2009), the intergovernmental Group on Earth Observations, the European Earth observation programme Global Monitoring for Environment and Security (Brachet 2004) and the Open Geospatial Consortium (OGC) Sensor Web Enablement Working Group (Botts et al 2008) have been launched. The results of these initiatives include case studies, information technology (IT) architecture best practices, Web services and definition of new standards, among others.…”
