GIS Interoperability
Presenters: Robert Laurini, University of Lyon INSA, Lyon, FranceThe goal of this workshop is to present the problems and the priciples of solutions in order that some interoperability will be possible between several GIS which appears
as a dream for users and a nightmare for system developers. Recently the creation of the Oen GIS Consortium has presented the problem in a very different way since several companies have decided
to work together in this direction through internet.

Dynamic Environmental Modelling
Coordinators/Presenters: Peter A. Burrough and Cees
Wesseling, Utrecht University, The Netherlands
GlS-based modelling of environmental phenomena is
becoming increasingly important for planning and land
management. It involves linking three different kinds of
activities, namely model building (to describe the physical
and chemical processes), data collection (to provide an
organised data structure for the automated handling of
the input data to the computations and for the display of
results). This workshop explains the various ways in which
numerical models can be linked to GIS, ranging from loose
coupling (the model is separate from the GIS being linked
only by a data interface) to embedded coupling in which
the GIS includes a high level dynamic modelling language.
The workshop will explain how data can be assembled
for dynamic modelling at regional and local scales,
including infommation about availability of data via the
Intemet and the problems and pitfalls associated with
assembling a database from a wide range of sources. The
main part of the workshop will introduce participants to a
new and highly efficient method of creating and running
environmental models using the PC Raster Dynamic
Modelling Language. The basic principles of the raster-
based approach will be explained and will be illustrated
with examples taken from actual case studies in hydrology,
ecology and land degradation. No skills in conventional
computer programming are necessary nor is expertise in
conventional GIS required. Participants will be provided
with an evaluation version of the Dynamic Modelling
Language to study at leisure.

Introduction to Spatial Interaction Modelling using SIMS
Coordinators/Presenters: Stan Openshaw, John Stillwell
and Linda See, University of Leeds, Leeds, United
Kingdom
The workshop offers participants a mainly non technical
introduction to both the theory and practice of the
complete range of Spatial Interaction Models. If you
wish to be brought up to date with what is happening
in this area, then this is the workshop for you. The work-
shop mixes theory with empirical applications using live
computer runs to illustrate the principles. Four very
deferent types of Spatial Interaction Models are covered:
1) conventional entropy and statistical types as currently
used in GIS and various decision support systems,
2) artificial neural network versions which offer black box
models capable of far higher levels of performance,
3) novel ways of breeding entirely new types of Spatial
Interaction Models using a genetic algorithm, and
4) the latest fuzzy logic based models that promise
the performance of a neural net based model whilst still
being capable of a simple interpretation.
The workshop
makes use of the PC based Spatial Interaction Modelling
System (SIMS) to be published by Geolnformation
International later in 1997 as a means of demonstrating
the different types and approaches to spatial interac-
tion modelling. This is a multimedia, self-contained,
computer-aided spatial interaction teaching and
research environment. It covers all the models dis-
cussed in the workshop together with a 100,000 word
help system and relevant papers. A beta version of
SIMS will be provided free to people who register for
the workshop.

Automated Large Scale Mapping in GIS
Coordinator: Erich Wilmersdorf, Magistrat der Stadt
Wien, Automatische Datenverarbeitung, Vienna, Austria
Regions and municipalities are installing voluminous
GIS databases for detailed analysis of manifold aspects
on the workstation. GIS offers an increased promptness
of geo-related information. But the central question is
how to manage instant cartographic visualization of
GIS analysis for multiple purposes on the working place.
In the focus will be the process of cartographic
modelling either for detailed or generalized information
based on cadastral maps or large scale maps of
topographic type (2- and 3-dimensional visualization).
Especially the aspect of thematic mapping will be
discussed. Ways of quick distribution of analogue and
digital cartographic data to the end-user (to the citizen,
to public or private service enterprises) will be described.
Finally the production of multicoloured maps will be
explained. In this context the production line from GIS
to final print ready films of high quality will be covered.

Cadastral Information Systems
Coordinator: Jerzy Gazdzicki, Delft University of
Technology, Delft, The Netherlands
The principles and practice of cadastral systems and
their ongoing reforms are discussed to help individual
countries and organizations address their own problems
Issues which are considered include the strategies for
development and improvement of cadastres, political,
legal and economic issues, state-of-the-art technological
solutions, and basic cadastre applications.
The principles and recommendations are illustrated by
a range of studies and projects from various countries.
The workshop offers an opportunity for cadastral
specialists and other interested parties to share
experience and new ideas.

Standardising of the Description of Geographical Information - Mete Data, Data Quality and Data Classifications
Coordinator Arto Nuora, The Association of Finnish
Local Authorities, Helsinki, Finland
Large databases of geographical information are
gathered at national as well as at local level without proper
description of contents or standards specifying it.
Availability of mete data would encourage wider use
of its data. Moreover, detailed description would tech-
nically ease interchange of data. This workshop will
present the draft European standards of mete data
and data quality. Examples of present national and inter-
national mete data services will be given as well.
European and ISO standardization approach for
description techniques will be discussed. The urban
data classification applied in Finland will be dealt with.

Quality Assurance in Large-Scale Mappers
Coordinator: J. Polman, Consultant, Apeldoom, The Netherlands
In many countries databases are built for large scale topographic and cadastral maps. Several sources for these databases are used, such as photogrammetric mapping, digital photographs, field surveying and existing maps. The geometric quality of the resulting databases is very dependent on the quality of the source information and on the production process. In order to develop a good system of geometric quality control a quality model has to be defined and testing procedures have to be developed for the production process as well as for the final product. The methods of geometric quality control will be discussed.

Key Issues in GIS Implementation: Raising Awareness and Educating GIS Professionals
Coordinator: Petra Cremers, GEON, Groningen,
The Netherlands
This workshop deals with the developments in the field
of GIS implementation and how these issues should
be addressed in GIS education. Both speakers are
authorities in the field of GIS implementation and are
experienced educators of academic students as well
as working professionals. Participants will gain an
insight in the issues that should be addressed while
implementing GIS, and more specific, the subjects
that should be included in the education programme.
Key questions are: Which are the critical success
factors of GIS implementation in an organization, how
should we raise awareness of GIS, how should we
define the need for GIS professionals and how should
these professionals be educated? This workshop will
offer the participants the unique opportunity to gain
experience from two well-known experts in the field of
GIS implementation and education.
