Age group influence for effectiveness’ study of color symbol scheme on choropleth map of population density in Special Region of Yogyakarta

摘要

Map can show information needed by map users from various scientific fields. Effective maps can help users tounderstand about the information inside. One of the factors that influence the effectiveness of map reading is colorsymbol scheme used in symbolization. Effectiveness’ study of color symbol scheme applied on choropleth mapping.Choropleth map visualized population density data in Special Region of Yogyakarta because the Special Region ofYogyakarta is one of the provinces in Indonesia which has a fairly high population density in the area of 3,185.80 km~2.In 2016, the population density of the Special Province of Yogyakarta ranked 4 th in the Indonesian Statistics 2017 by theCentral Bureau of Statistics, which amounted to 1,188 population per km~2. All scientific field that used choropleth mapof population density consist of 2 age groups, those are 20-25 years old and >25 years old respondents. Visual abilities indifferent age groups of map users can be accommodated with this research. The effectiveness of color symbol schemesadapts the capabilities of each user. This study is expected to be able to study the effect of age group differences on mapswith the best color symbol scheme. The purpose of this study was to observe age group influence for the most effectivecolor symbol scheme for mapping population density in the Special Region of Yogyakarta. The result of this studyshows the difference between age group based on the important aspects of conventional-eye tracking. The importantaspects to consider are average answering duration, the accuracy of the answer and easiness level of symbolizationreadings. The first group (20-25 years) shows map 3 (diverging color scheme) as a map with the most effective colorsymbol scheme. While group 2 (> 25 years) shows map 1 (ArcGIS 10.3 color scheme) as a map with the most effectivecolor symbol scheme. This research is expected to be able to show the influence of age in determining the best colorsymbol scheme on population density maps so that its effectiveness can be adjusted specifically to map users.
