Book Synopsis Elements of Spatial Data Quality by : S.C. Guptill
Download or read book Elements of Spatial Data Quality written by S.C. Guptill and published by Elsevier. This book was released on 2013-10-22 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: Elements of Spatial Data Quality outlines the need and suggests potential categories for the content of a comprehensive statement of data quality that must be imbedded in the metadata that accompanies the transfer of a digital spatial data file or is available in a separate metadata catalog. Members of the International Cartographic Association's Commission on Spatial Data Quality have identified seven elements of data quality: positional accuracy, attribute accuracy, completeness, logical consistency, lineage, semantic accuracy and temporal information. In the book the authors describe: components of each data quality element, possible metrics that can be used to measure the quality of each criteria, possible testing and rating schemes, and how these parameters might differ from a producer or user point of view. Finally no volume of this nature would be complete without a chapter devoted to necessary future research in this subject area. The chapter points out areas in need of further investigation and speculates about the use and transfer of digital spatial data in tomorrow's electronic world and at developments in presenting specified data quality information in a visualization. This book will be of interest to all of those individuals involved in geographical information systems and spatial data handling.

Book excerpt: As research in the geosciences and social sciences becomes increasingly dependent on computers, applications such as geographical information systems are becoming indispensable tools. But the digital representations of phenomena that these systems require are often of poor quality, leading to inaccurate results, uncertainty, error propagation, and
Book Synopsis Fundamentals of Spatial Data Quality by : Rodolphe Devillers
Download or read book Fundamentals of Spatial Data Quality written by Rodolphe Devillers and published by John Wiley & Sons. This book was released on 2010-01-05 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explains the concept of spatial data quality, a key theory for minimizing the risks of data misuse in a specific decision-making context. Drawing together chapters written by authors who are specialists in their particular field, it provides both the data producer and the data user perspectives on how to evaluate the quality of vector or raster data which are both produced and used. It also covers the key concepts in this field, such as: how to describe the quality of vector or raster data; how to enhance this quality; how to evaluate and document it, using methods such as metadata; how to communicate it to users; and how to relate it with the decision-making process. Also included is a Foreword written by Professor Michael F. Goodchild.

Book Synopsis Issues of Accuracy, Precision and Error in Gis Dat by : Md. Asaduzzaman
Download or read book Issues of Accuracy, Precision and Error in Gis Dat written by Md. Asaduzzaman and published by LAP Lambert Academic Publishing. This book was released on 2011-10 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prior to GIS (geographic information system), maps were used mainly for strategic planning. As a result, high spatial accuracy was not required. So, errors in spatially referenced data were ignored or considered acceptable. The situation changed today. Accuracy is a great matter of concern for not only increase of land's monetary value but also for decision making and so on. In Bangladesh, most of the physical planning projects are using GIS for preparing map and making decision but a lion's share of the data are inaccurate having spatial and attribute error. The more accurate a dataset will be, the more perfect and precise the outcome will be. As imperfection severely limits the usefulness of a dataset especially for GIS, users as well as the specialists need to be very careful regarding errors and managing them. This work is based on some observations especially, some GIS data that the planning authorities of Bangladesh have prepared. Bangladesh is using GIS until very recently and thus, there is a huge scope to improve its data and database.
