Auto-Carto X

Proceedings of the International Symposium on Computer-Assisted Cartography

March 25 - 28, 1991

Baltimore, Maryland


This volume contains the 27 papers of the Tenth International Symposium on Computer- Assisted Cartography. AUTO-CARTO 10 represents a new direction for the series. (Only time will tell whether it was the start of a new course, or a temporary detour!) For the first time, full papers were peer-reviewed by at least two, and often three or four, members of the program committee. Furthermore, accepted papers were returned to the authors for revision based on the reviewers comments. Our announced plan was to accept between 30 and 40 papers, and we expected to select those from a pool of perhaps 100 submissions. Based on that expectation, a large program committee with a total of 22 members was established to conduct the reviewing and to advise on final program decisions; the program committee co-Chairs wish to thank all the members of the committee for their timely and conscientious reviewing and other participation in the decision-making process.
