Effectiveness of Classification Method and Color Symbol Scheme on Choropleth Map of Population Density in Special Region of Yogyakarta

Abstract

Abstract. The need for presenting information in maps is increasingly high in various scientific fields. All scientific fields need to present effective data for decision making. Good decision making based on maps requires good understanding but not all scientific fields are familiar with using maps. Supporting factors for easy maps to understand are classification method and color symbol scheme. The purpose of this study was to select and test the classification method and the most effective color symbol scheme for mapping population density in the Special Region of Yogyakarta. The classification methods used in this study are constant interval, arithmetic progression, geometric progression, quantile, standard deviation and dispersal graph. The effectiveness test method for the most effective classification method is the proportion assessment. The color symbol scheme used in this study is a sequential color scheme, diverging color schemes, Corel Draw color schemes and color symbol schemes provided in ArcMap 10.3 software. The effectiveness test method for the most effective color symbol scheme is conventional eye tracking. The results showed that according to the proportion test the most effective classification method was the arithmetic interval classification method with results of 0.26. The most effective color symbol scheme in accordance with the effectiveness test using the conventional eye tracking method shows that the most effective color symbol scheme is a diverging color scheme. The important aspects to consider are average answering duration of 8.15 seconds, the accuracy of the answer is 98.9%, and easiness level of symbolization readings is 341. This research can be one of the references on the most effective classification method and reference regarding the selection of the most effective color symbol scheme on Choropleth Map of Population Density in Special Region of Yogyakarta, so that further research can continue the analysis of appropriate classification methods for demographic data. The method discussed in this study is also expected to be applicable to other data.

Study on the analysis of demographic data based on spatial information systems

“…The Special Region of Yogyakarta is one of the provinces in Java island, Indonesia, and consists of 4 districts and one city, each district being further divided into 78 subdistricts. [3] In carrying out the administration of demographic data, the provincial government also often faces problems, such as the asynchronous between data at the provincial government and data at the sub-district level. This also causes data confusion, for example, the unemployment data at the sub-district level if the total is one hundred people, but when compared to the provincial level data, the female population does not reach one hundred people.…”
