Abstract
Generalizing Features to Improve ArcIMS Performance: A Practical GuideTrack: Application Development
Author(s): Linc Clay, Dixie M. Davis
Two issues facing ArcIMS developers are feature generalization and symbolization. The need for feature generalization is noted in the literature, but few guidelines are presented. What is the relationship between layer size and drawing speed? Are there size thresholds below which generalization is not beneficial? What does generalization do to feature quality? A related question involves symbology. Is it faster to draw multiple layers or use value map renderers on one larger layer? Does the answer vary with layer size and map scale? This paper presents the results of our efforts to develop generalization and symbolization guidelines using ArcIMS performance tests.
