ISPRS Commission II
Systems for Data Processing, Analysis and Representation
Foreword
During the period of 1992 - 1996 responsibility for Technical Commission II - Systems for
Data Processing, Analysis and Representation - of the International Society for
Photogrammetry and Remote Sensing resided with Geomatics Canada. Under the
Commission, five Working Groups, one Inter-Commission Working Group and one Special
Topic were active in promoting research and activities in the following areas:
Real-time mapping technologies;
Hardware and software aspects of GIS;
Technologies for large volumes of spatial data;
Systems for the processing of RADAR data;
Integrated production systems;
Digital photogrammetric systems; and
Upgrading photogrammetric instruments.

Commission II held its Technical Symposium in Ottawa, Canada from June 6 - 10, 1994 in
conjunction with the Sixth Canadian Conference on GIS. Under the theme "a Shared
Vision", the meeting provided an excellent technical program that extended over a five-day
period.
The recent past has demonstrated that our progress has been driven by advances in
technology - GIS, soft-copy photogrammetry, remote sensing, GPS, and information
technology (DBMS, communication and networking). It is clear that as technological
advances continue they will have a major impact on how systems and information are
applied to real world problems. An important aspect of such advances will be measured by
degree of integration and communication between systems and data.
The following volume is dedicated to continuing the advancement of systems for data
processing, analysis and representation. It represents the hard-work and research of many
persons from many parts of the world, who collectively continue the ISPRS tradition of
cooperative technological advancement and scientific achievement.
In closing, thanks is extended to all WG chairpersons, co-chairpersons and secretaries of
Commission II, who have worked hard over the four years in preparation of the Vienna
Congress. Special thanks is also made to our colleagues in the Geographic Information
Systems and Service Division, Geomatics Canada.
