Proceedings foreword

The Scandinavian Research Conference on GIS (ScanGIS) is a forum for Geographic Information Systems (GIS) researchers in Scandinavia. This years ScanGIS is the 6th in order.

The first ScanGIS was arranged in Linköping, Sweden in 1985, and the venue has ever since been carried from one country to the other. Other meetings took place in Norway, Denmark and the fourth conference was held in Finland in 1992. The fifth conference was held in Trondheim in 1995 and now, finally, the sixth conference will be held in Stockholm.

During the last few years, a large number of conferences on the subject of geographic information S... has come about. Also, for the first time we have elicited not only abstracts but full length papers and through a simple review process tried to select the "best" papers. This, I think has negatively affected the number of papers submitted. However, the papers that have been submitted are all of good quality.

During this years conference we will again have to discuss the future of this venue. Is a ScanGIS really needed? I personally think so.

For the second time the conference was almost exclusively announced over the infamous internet. All papers for this proceedings have been submitted in electronic form and, after some amount of editing, been assembled into this volume. I apologize to authors in whose papers I had to rearrange figures in order to make color economically feasible. I hope I have not destroyed your papers.
