Book Description
This book represents five and a half years of work by the ICA Commission on Standards for the Transfer of Spatial Data during the 1991- 95 ICA cycle. The effort began with the Commission working to develop a set of scientific characteristics by which every kind of spatial data transfer standard could be understood and assessed. This implies that every facet of the transfer process must be understood so that the scientific characteristics could be most efficiently specified. The members of the Commission spent hours looking at their own standard and many others, to ascertain how to specify most effectively the characteristic or subcharacteristic in question. The result is a set of internationally agreed scientific characteristics with 13 broad primary level classes of characteristics, 85 secondary characteristics, and about 220 tertiary characteristics that recognizes almost every possible capability that a spatial data transfer standard might have. It is recognized that no one standard possesses all of these characteristics, but contains a subset of these characteristics. However, these characteristics have been specified in such a way to facilitate understanding of individual standards, and use by interested parties of making comparisons for their own purposes. Although individual applications of a standard may be for different purposes, this set of characteristics provides a uniform measure by which the various standards may be assessed. The book presents an Introduction and four general chapters that describe the spatial data transfer standards activities happening in Europe, North America, Asia/Pacific, and the ISO community. This provides the context so the reader can more easily understand the scientific and technical framework from which a particular standard has come. The third section is a complete listing of all of the three levels of characteristics and their meaning by the inclusion of a set of definitions for terms used in the book. The fourth section, and by far the largest, contains 22 chapters that assess each of the major national and international spatial data transfer standards in the world in terms of all three levels of characteristics. Each assessment has been done by a Commission member who has been an active participant in the development of the standard being assessed in the native language of that standard. A cross-table chart is also provided.

Book Description
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 Description
A concise text presenting the fundamental concepts in Geographical Information Systems (GIS), emphasising an understanding of techniques in management, analysis and graphic display of spatial information. Divided into five parts - the first part reviews the development and application of GIS, followed by a summary of the characteristics and representation of geographical information. It concludes with an overview of the functions provided by typical GIS systems. Part Two introduces co-ordinate systems and map projections, describes methods for digitising map data and gives an overview of remote sensing. Part Three deals with data storage and database management, as well as specialised techniques for accessing spatial data. Spatial modelling and analytical techniques for decision making form the subject of Part Four, while the final part is concerned with graphical representation, emphasising issues of graphics technology, cartographic design and map generalisation.
