Book Description
Tile-based mapping systems have grown to become the dominant form of mapping system with the rise of Web-based mapping tools. The origin of this book is a desire to collect all our discoveries, techniques, and best practices for creating a til- mapping system into one combined volume. The intent of this text is to provide a comprehensive guide to the theory behind creating a tiled-map system as well as a practical guide to create a concrete implementation.

Book Description
The late 20th century has witnessed increasing crises in the world's marine fisheries. A causal analysis of these reveals that a common element are various manifestations of spatial inequity. This most frequently includes the inequity of access rights to the resource, but factors such as variations in resource depletion, spatio-temporal variations in stock recruitment, the imposition of regulatory zoning, destruction of marine ecosystems and the siting of mariculture facilities are other examples. To resolve some of these problems, management practices must be improved. As has been shown in other fields where spatially related problems occur, there is now a promising tool, Geographical Information Systems (GIS), which, combined with other analytical tools and models, could allow for improved spatial management. GIS are basically integrated computer based systems which allow for the input of digital geo-referenced data to produce maps plus other textual, graphical and tabular output. The essential usefulness of GIS however, lies in its ability to manipulate data in a large number of ways and to perform various analytical functions so as to produce output which makes for more efficient decision making.As with many computer based systems, the key to GIS success lies in the acquisition of suitable data. The various means by which both primary and secondary data can be located, gathered, accessed and stored are described.

Book Description
Author’s experience in GIS applications, training courses and lectures at various institutions has led him to the appreciation of gaps in the understanding of some fundamental aspects of GIS. This is but natural. GIS is a technology which integrates several technologies. GIS has attracted persons from a varied types of fields. Author is from the field of Surveying & Mapping. This book is based on notes/presentations by the author. Though presented in the form of chapters, some repetition could not be avoided. Even then at places readers will ignore abrupt endings. See the preface and note on cover page.. Geomatics, GeoInformation Technlogy, Spatial Information technology, GeoSpatial Technology are some other names of GIS. This is a natural outcome because GIS has embraced many disciplines and Technologies. Most of the IT Companies have GIS departments. India with focus on development, needs GIS in many sectors. There is an impression that implementing GIS is expensive. Author brings out the fact that cost of comprehensive GIS data base comes to Rs 50 per household ( cost of house in lakhs of rupees ) in urban areas and Rs 200 per acre(Cost of one acre is in lakhs of rupees ). Policy issues are covered. Changes to simplify applications and political will are two important requirements for implementing GIS in India. This book helps all those interested in implementing GIS. This complements standard books, websites and their own experience.Author’s experience in GIS applications, training courses and lectures at various institutions has led him to the appreciation of gaps in the understanding of some fundamental aspects of GIS.
