Download or read book Structure and Flow of Data Through an Environmental Data Management System written by and published by . This book was released on 1993 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: Efficient data management is crucial to environmental investigations. The management system must provide for organized data tracking, storage, and retrieval of data essential to successful environmental management. Ultimately, the system is used as an environmental management tool for remediation decisionmaking. This paper will describe the structure and flow of data in the data management system used by the Environmental Restoration Division of the Environmental Protection Department of Lawrence Livermore National Laboratory (LLNL). The structure is based on three relational databases that are closely correlated. The first database handles sample tracking. The second database handles nondiscrete data, such as sample location, media, analytical results, and some geological information. These two databases are maintained on a VAX 63 10 with VMS, using INGRES relational database software. The third database handles nondiscrete data like graphic imaging flies and geophysical logs and will be run on an IPC Sparc, using INGRES. The flow of data, both hard copy and electronic, follows a model that tracks information from sampling plan through decisionmaking (Fig. 1). The steps in the process include chain-of-custody (CoC) tracking of the sample, receipt of analytical results, application of quality control procedures. and electronic use of data in decision support tools, such as graphic imaging, model development and verification, or statistical analysis.

This book was released on 2012-12-06 with total page 550 pages. Available in PDF, EPUB and Kindle. Book excerpt: An integrated approach to environmental data management is necessitated by the complexity of the environmental problems that need to be addresses, coupled with the interdisciplinary approach that needs to be adopted to solve them. Agenda 21 of the Rio Environmental Conference mandated international programmes and organizations to take steps to develop common data and information management plans, and steps have been taken in this direction. The key word that defines the framework of the present book is `integration'. The book establishes the basics of integrated approaches and covers environmental data management systems within that framework, covering all aspects of data management, from objectives and constraints, design of data collection networks, statistical and physical sampling, remote sensing and GIS, databases, reliability of data, data analysis, and the transformation of data into information.

Download or read book Environmental Data Management written by Nilgun B. Harmanciogammalu and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 443 pages. Available in PDF, EPUB and Kindle. Book excerpt: The diverse nature of environmental problems mankind has encountered within the last decade has developed a new understanding of the nature of environmental processes. Currently, the environment is considered as a continuum of air, soil and water as the vital components for sustaining life on earth. The interactive nature of these components requires that the environment is managed and protected as a cohesive whole. This can only be accomplished through an integrated approach to environmental management. Besides the concept of environmental continuum, prospects for sustainable development of natural resources and the recent recognition of global climate change impacts have also necessitated such an integrated approach to environmental management. Two basic tools for integrated management of the environment are modeling and environmental data. Both tools were available and valid in the past; however, the recent requirements for integrated environmental management have also led to a significant evolution of both modeling procedures and data management systems.

Available in PDF, EPUB and Kindle. Book excerpt: ENVIRONMENTAL MANAGEMENT SERIES The current expansion of both public and scientific interest in environ mental issues has not been accompanied by a commensurate production of adequate books, and those which are available are widely variable in approach and depth. The Environmental Management Series has been established with a view to co-ordinating a series of volumes dealing with each topic within the field in some depth. It is hoped that this Series will provide a uniform and quality coverage and that, over a period of years, it will build up to form a library of reference books covering most of the major topics within this diverse field. It is envisaged that the books will be of single, or dual authorship, or edited volumes as appropriate for respective topics. The level of presentation will be advanced, the books being aimed primarily at a research/consultancy readership. The coverage will include all aspects of environmental science and engineering pertinent to manage ment and monitoring of the natural and man-modified environment, as well as topics dealing with the political. t:conomic, legal and social con siderations pertaining to environmental management.

Download or read book Environmental Data Management in Support of Sharing Data and Management written by Dr Tim Whiteaker and published by CreateSpace. This book was released on 2014-08-01 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: A data management system (DMS) was developed, tested and demonstrated to store and manage water quality and quantity (WQ2) data pertaining to U.S. Environmental Protection Agency/Office of Research and Development (EPA/ORD) research projects in standardized formats. This approach was taken to facilitate accessibility, sharing, integration, and use of this information for simple calculations and inclusion into models by EPA and other users to inform water management decisions. The objectives of this project were: (1) Build a previously identified hydrologic information system (HIS) Observational Data Model (ODM) and convert existing water quality and quantity data, generated by EPA/ORD-research projects, into this format; (2) Develop, test and demonstrate a scalable DMS based on HIS protocols for storage and management of geo-referenced data; and (3) Enable targeted users to access, exchange and integrate geospatially referenced WQ2 information, and to conduct relatively simple calculations and/or run models to inform water management decisions at various watershed scales. The HIS developed by the Consortium of Universities for the Advancement of Hydrologic Science Inc. (CUAHSI) was used in this project. The CUAHSI HIS ODM model is widely accepted in the United States, is compatible with the National Water Quality Portal, and is gaining international acceptance as the standard for water data. This HIS is web-based, and uses the WaterML format for sharing hydrologic time series data. Within the U.S., many organizations measure WQ2 and various biological parameters. Despite the fact that this information is routinely made available to the public, the difficulties in identifying data sources, syntactic and semantic heterogeneity across data formats and metadata make the discovery, access and interpretation of data challenging for research and other stakeholder communities. EPA-ORD seeks to alleviate these challenges and plans to use CUAHSI's HIS and other tools to integrate time series data generated within its local, regional and national watershed projects with data collected by collaborators, and to share these data with other interested parties.

This book was released on 2012-12-06 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the proceedings and the outcomes of the NATO Advanced Research Workshop (ARW) on Integrated Technologies for Environmental Monitoring and Information Production, which was held in Marmaris, Turkey, between September 10- 14, 200 I. With the contribution of 45 experts from 20 different countries, the ARW has provided the opportunity to resolve the basic conflicts that tend to arise between different disciplines associated with environmental data management and to promote understanding between experts on an international and multidisciplinary basis. The prevailing universal problem in environmental data management (EDM) systems is the significant incoherence between data collection procedures and the retrieval of information required by the users. This indicates the presence of problems still encountered in the realization of; (1) delineation of objectives, constraints, institutional aspects of EDM; (2) design of data collection networks; (3) statistical sampling; (4) physical sampling and presentation of data; (5) data processing and environmental databases; (6) reliability of data; (7) data analysis and transfer of data into information; and (8) data accessibility and data exchange at local, regional and global scales. Further problems stem from the lack of coherence between different disciplines involved in EDM, lack of coordination between responsible agencies on a country basis, and lack of coordination on an international level regarding the basic problems and relevant solutions that should be sought.

Available in PDF, EPUB and Kindle. Book excerpt: Environmental information systems (EIS) are concerned with the management of data about the soil, the water, the air, and the species in the world around us. This first textbook on the topic gives a conceptual framework for EIS by structuring the data flow into 4 phases: data capture, storage, analysis, and metadata management. This flow corresponds to a complex aggregation process gradually transforming the incoming raw data into concise documents suitable for high-level decision support. All relevant concepts are covered, including statistical classification, data fusion, uncertainty management, knowledge based systems, GIS, spatial databases, multidimensional access methods, object-oriented databases, simulation models, and Internet-based information management. Several case studies present EIS in practice.
