Data Structures and Data Models in GIS
In Geographic Information (GI) technology, it is essential to find suitable mappings between the — one and only — ‘real world’ and — several possible — ‘virtual worlds’ that constitute greatly simplified copies of the original, omitting aspects that are i

PREFACE
The International Centre for Mechanical Sciences hosted from 12 to 16 June 1995 the Workshop on "Multimedia GIS Data" organized by the Technical Commission One of the International Society for Photogrammetry and Remote Sensing. On that occasion a tutorial on "Spatial Data Analysis: Theory and Algorithms" was also organized by the Working Group III/IV of the same Society. The book contains the proceedings of both events and is made up of 27 papers, presented in 1O technical sessions of the workshop, on different fields of application, and 4 more papers given by invited speakers at the one-day tutorial. The papers reported in the book and presented at the workshop can be ideally collected in five main chapters. In the first one, that can be defined "guidance and navigation ", some experiences on data acquisition with low cost DGPS for road survey and an overview on Vehicle Navigation Systems (VNS) are shown. An original method for a mobile robot to explore an unknown environment is also reported. The second chapter on "GIS data acquisition and evaluation" collects a sort of papers treating robust statistica/ techniques applied to preprocessing, analysis and te sting for dif.ferent kinds of GIS data. Within the topic on "image acquisition and preprocessing" in particular some experiences on test and calibration of different
