The purpose of this paper is to investigate the cartographic characteristics of French statistical graphical album of the last half of 19th centuries. This paper begins by considering the development background of the 19th century French thematic mapping. Social engineering and statistical graphics played most important roles in the production of this atlas. Secondly, themes of maps are mainly concentrated on transportation network for the cost benefit analysis. Thirdly, for choropleth maps, equal intervals and natural breaks are used for data classification and sequential scheme and red-yellow diverging scheme were selected to measure nominal level. Fourthly, for flow maps, line’s width is made proportional to magnitude of the volume of traffic, and color and texture are used for the difference of traffic type. Fifthly, for proportional symbols maps, multivariate maps which represent more than four attributes are numerous and they cause some difficulty for map reading. Sixthly, cartograms are used for representation of time space convergence and cost space convergence.

This study investigated American undergraduate students’ understandings of the concepts of projection and scale. First, in terms of the concept of projection, students who are non-experts in cartography believed the reason the great circle route is not shown as a straight line on maps as follows: 1) to control air transportation and to prevent collision between airplanes, 2) to avoid obstacles such as big mountains, 3) to transfer an airplane, and 4) to be affected by the Coriolis force. Second, the most common misunderstanding regarding the concept of scale was the confusion resulting from the terms, large and small scales, which has been commonly reported in the literature. Most students believed that the large scale map represents the large area because of the term ‘large.’ In addition, several students did not have the concept of scale. This research merits inclusion in the literature because it provides empirical data associated with two important cartographic concepts, or projection and scale. The findings of this study could be beneficial for the design of map-relevant information and the development of effective geography education strategies.

The national land-cover maps (2000 and 2009) produced by Korea Ministry of Environment are used as a basic information in various studies such as hydrological, ecological study, and vulnerability assessment of natural hazard. However, the difficulty lies in using the national land-cover maps for analysis of land-cover change due to the lack of accuracy in the national land-cover 2000 map. This study aimed to make a method to estimate the area about each land-cover in the year 2000 using a national land-cover 2009 map and land categories data of statistical yearbooks. We applied the method to estimate the area of each land-cover classification for evaluating the efficiency of the method in 6 sites near the DukYuSan (mountain). In the results, the difference between the estimated area of the year 2000 and the area in a statistical yearbook was overall 6.12 km2, compared to 13.10 km2 between a national land-cover 2000 map and the area in a statistical yearbook. Trends of land-cover changes (2000～2009) in the national land-cover maps correspond to the trends in the statistical yearbooks 54.2%, compared to 95.8% for the estimated changes. The results show that suggesting estimation method in this study can be useful to estimate the area about each land-cover in the year 2000 rather than using only national land-cover maps.
