Allan Brimicombe & Chao Li 
Location-Based Services and Geo-Information Engineering [PDF ebook] 

Location-Based Services (LBS) are the delivery of data and
information services where the content of those services is
tailored to the current location and context of a mobile user. This
is a new and fast-growing technology sector incorporating GIS,
wireless technologies, positioning systems and mobile
human-computer interaction. Geo-Information (GI) Engineering is the
design of dependably engineered solutions to society’s use of
geographical information and underpins applications such as LBS.
These are brought together in this comprehensive text that takes
the reader through from source data to product delivery.

This book will appeal to professionals and researchers in the
areas of GIS, mobile telecommunications services and LBS. It
provides a comprehensive view and in-depth knowledge for academia
and industry alike. It serves as essential reading and an excellent
resource for final year undergraduate and postgraduate students in
GIScience, Geography, Mobile Computing or Information Systems who
wish to develop their understanding of LBS.
