This paper discusses the challenges in operational crisis management and describes the role of information and geo-spatial technologies in meeting those challenges. The paper discusses two main sources of data, Web and very high resolution (VHR) earth observation sensors, in terms of relevance to crisis management and techniques for information extraction and analysis. Although research in information text extraction and analysis is more advanced than in information image extraction and analysis, further research is required in both these fields to take advantage of the increasing complexity but richness of open source and VHR satellite data. The paper also discusses the use of Web, GIS and Digital Earth technologies in facilitating collaborative work, decision-making and information sharing in crisis management. Despite exciting and relevant advances in information sources, information extraction and analysis methods, and collaborative crisis technologies, the main challenge remains to convince stakeholders in operational crisis management that the adoption of these technologies will lead to enhanced and effective crisis management.

Spatial information especiallly Digital Earth technology have been put forward for about 50 years. Now it has been applied in different area successful such as city management, landuse monitor, digital city and even globe change. In the field of geology and mining, it also needs the Digital Earth technology to make it clear that how does the different stratums and geology structures being under the ground and where the mine is being. Because of the complexity of geology field, there is few successful report on the application of Digital Earth technology in this area. In this paper, we just put forward a new method which will integrate all kinds of geology and mining data together, using spatial information technology to develop a 3D geology and mining data sharing platform. In this platform, users can find the different stratums location and development, they can also search some element of features, located them and viewed them in 3D model. This platform has changed the traditional geology data's access and using.

Digital Earth is a comprehensive multidisciplinary research area, covering earth science, space science, information science, and computer science and technology. Digital Earth was originally described as a multiresolution, three-dimensional visual representation of Earth that would help humankind take advantage of geo-referenced information on physical and social environments. With more than two decades advancement, Digital Earth technology has been developed to monitor, model, and analyze the Earth with a multidimensional, multiscale, multitemporal, and multilayered information system in terms of various aspects of human societies. Digital Earth also serves as a common platform supporting domestic and international cooperation for global sustainable development, climate change, and disaster mitigation. It has become a new growth point of the social economy and of social welfare. This article gives an overview of how Digital Earth technologies have been developed, and how it has been applied in different domains and at regional/national scales during the last two decades. Through this article, the aim is to provide researchers with a comprehensive instruction in understanding the Digital Earth discipline.

Large amounts of valuable geosciences data have been collected due to the advances in digital earth technology. How to provide an efficient way through which researchers can easily retrieve desired data to facilitate data analysis and system modeling poses great challenges to the geosciences community. This paper presents a Geo-web services based system aimed to enhance geospatial data searching and visualization. The system provides an interoperable way of searching and accessing high quality geospatial data from multi-source and multi-discipline geographic data repositories through the use of Open Geospatial Consortium (OGC) Web services. It is in conformity with OGC Catalog Service for the Web (CSW) specification to play a "directory" role that permits the registry, discovery and access of geospatial information resources distributing on the Internet. Moreover, by leveraging the Rich Internet Applications (RIAs) technologies, the system enables to seamlessly assemble multiple heterogeneous data from different sources into one single user interface for visualization. Two investigations were made to demonstrate how this system has been used to improve the efficiency of searching and collecting geospatial data for a particular research.

Digital Earth's framework can be traced to evolutionary threads with historic foundations that fostered the fertile conceptual and technological incubation. These threads incorporate writings, such as those of the visionary engineering-genius, Buckminster Fuller, in conjunction with an array of space age developments in computers, internet and communications, satellites, and education. In 1998, when Vice President Al Gore articulated the Digital Earth Vision, he portrayed the vision based upon myriad technology factors for the intellectual foundation and sparked a worldwide phenomenon that fortuitously included the Chinese leadership's recognition and acceptance. The Beijing Declaration is recognised for its role promulgating the International Digital Earth Symposium series to promote better understanding of the impacts of Digital Earth technology and applications on behalf of all humankind. Combinations of industrial, academic, and government organisations have advanced the technological components necessary for implementing the Digital Earth Vision at a prodigious rate. Commercial leaders, such as Google, have accelerated the influence of large segments of society towards components of the Digital Earth Vision. However, challenges still remain regarding requisite collaboration on international standards for metadata, interoperability, and data formats for space and time that will affect Digital Earth implementation scenarios. Functional requirements for the model Digital Earth geobrowser remain to be fully articulated. The current paper presents an overview of the historical components, the key players on the international scene, the catalytic technological advances, and the societal response to the growth of the Digital Earth community.

This paper explores the development of digital and green collaboration, empirically examining both the linear and nonlinear impacts of the convergence of digital and green technologies on regional total factor productivity (TFP). Using data from 30 provinces and cities in China from 2010 to 2022, the study constructs a panel threshold model with business environment and intellectual property protection as threshold variables to investigate their roles in mediating the effects of digital–green technology convergence on regional TFP. The key findings are as follows: (1) The linear analysis reveals that the convergence of digital and green technologies significantly enhances regional TFP. (2) The nonlinear analysis demonstrates a nonlinear relationship between the convergence of these technologies and regional TFP. (3) The threshold effect test identifies a single-threshold effect for the business environment, showing that once the threshold is surpassed, the positive influence of the convergence of digital and green technologies on TFP increases. Additionally, a double-threshold effect is found with intellectual property protection; as intellectual property protection surpasses the first and second thresholds, the positive impact initially strengthens but then weakens. (4) A heterogeneity analysis shows that the convergence of digital and green technologies significantly contributes to TFP in the eastern regions, while the effects in central and western regions are not significant.

Intrinsic value of food chain data

SEAMONSTER: A demonstration sensor web operating in virtual globes

Research background: Digital technologies aim to enhance efficiency, competitiveness, and sustainability. Despite ongoing efforts, Hungary is encountering various challenges in digitalization. This research seeks to investigate the potential of digital technologies in addressing these challenges, with a particular focus on precision agriculture technologies (PA). Purpose of the article: This study explores the utilization of digital technologies among 81 agricultural and food companies in Hungary. The study evaluates the use of advanced and less advanced digital technologies and their impact on rural areas. Additionally, the research seeks to understand the economic and social impacts resulting from the adoption of these technologies, focusing specifically on precision farming. Methods: The study uses advanced clustering methods to categorize agricultural companies based on their use of digital technology. The research employed the two-step clustering method, which has been recognized for its robustness in clustering mixed-level variables. Findings & value added: Farmers and food producers generally have low adoption rates of advanced digital technologies, preferring common but less advanced tools. This is mainly due to high investment costs, economies of scale, limited experience and expertise, and a lack of willingness to cooperate among farmers. The respondents could be classified into two groups: one group is aware and even understands advanced technology, but rarely uses it. In contrast, the other group is largely unaware of these technologies. The results indicate that a lack of knowledge and expertise can significantly impede the adoption of advanced technologies in agriculture. Policymakers must develop a mix of policies that collectively reduce the economic barriers to technology adoption while engaging stakeholders who may not fully understand the benefits of advanced technologies.

Digital Earth technologies [1] collate rich information about the physical world around us from sensors to create digital twins. Digital Twins integrate multi-dimensional geometric representations, internet of things, artificial intelligence (AI) and analytics. Graph based digital threads trace all lifecycle transactions and associations to ensure the integrity of this cyber-physical coupling. Through metaphors such as virtual globes we can apply this framework to build a deeper and more collaborative understanding of the complex dynamic interactions in our physical world and what bearing these may have on our wellbeing.

ABSTRACTLong-term observation of the earth is essential for studying the factors affecting global environmental changes. Digital earth technology can facilitate the monitoring of global environmental change with its ability to process vast amounts of information. In this study, we map the forest cover change of Myanmar from 2000 to 2005 using a training data automation procedure and support vector machines algorithm. Our results show that Myanmar's forests have declined 0.68% annually over this six-year period. We validated our derived change results and found the overall accuracy to be greater than 88%. We also assessed forest loss from protected areas, areas close to roads, and areas subject to fire, which were most likely to lose forested area. The results revealed the main reasons for forest losses in some hotspots to be increased agricultural conversion, fire, and the construction of highways. This information is useful for identifying the driving forces behind forest changes and to support environmental policy development in Myanmar.

The space-ground integrated network is one of the important information infrastructures of the country in the future. In order to display its network structure in all directions and from multiple angles, a multi-view visualization interactive analysis method is proposed. First introduces the relevant basic technology, and then constructs the network dynamic model, which is mainly divided into three parts: link visibility analysis, relative motion analysis and visualization model construction. Finally, the digital earth technology is based on a unified coordinate system and data source. Establish a multi-dimensional view on it and provide a variety of interactive operations. Experimental results show that this method can more comprehensively show the structure of the space-ground integrated network, and help users understand its evolutionary law.

The geospatial location of stationary and mobile objects and phenomena are increasingly important to geospatial applications. The availability and ease of access to geospatial information and digital earth technologies via the Internet are helping to drive a greater demand for geolocating fixed and mobile features, users, assets, services and other phenomena. A range of methods are used to determine spatial locations of fixed and mobile objects and properties including GPS, WiFi, RFID, geocoding, sensors and IP locating. Current research is investigating methods to identify user locations on the internet. The internet forms an attractive platform for Location Based Services (LBS) since it provides a nearly ubiquitous medium and web browsers provide a highly standardised application environment. However, security mechanisms in browsers complicate communication with devices used for positioning. IP positioning can provide a viable alternative, particularly since the computer network hierarchy is related to spatial hierarchies. This chapter introduces location based services and the importance of location. A range of methods for obtaining geospatial location are introduced and the contexts in which they are used are described. Finally, some current research is outlined where a methodology known as VRILS was developed to enable the use of IP addresses for geolocating in a web based environment.
