This study investigated six teachers who used the lessons utilizing geospatial technologies including GPS and Google Earth. The lessons were designed to ask students to solve problems with the technologies rather than to teach students to just use technology and teachers to function more as a facilitator. Key findings include: (1) The teachers with background and interest in learner-centered teaching were more effective in implementing the lessons with their students while the teachers who were familiar with teacher-centered instruction often reduced learners' roles in the lesson; (2) Generally, students expressed huge interests in the lessons. Changes in attitude and participation toward lessons were more clearly observed from low achievers and passive learners; (3) Key influencing factors in adoption of lessons utilizing geospatial technologies were school culture toward innovativeness, characteristics of school administrators, learning experience of the lessons during the workshops, and support systems for lesson preparation and implementation.

Content used in mashups is typically obtained from a third party source through a public interface or API (web services). Other methods of obtaining content for mashups include Web feeds (e.g. RSS or Atom), and screen scraping. A mashup or meshup Web application has two parts: A new service delivered through a Web page, using its own data and data from other sources. The blended data, made available across the Web through an API or other protocols such as HlTP, RSS, REST, etc. There are many types of mashups, such as consumer mashups, data mashups, and Business Mashups. The most common mashup is the consumer mashup, which are aimed at the general public. Examples include Google Maps, iGuide, and RadioClouds. 4D Wall-map display is data mashups combine similar types of media and information from multiple sources into a single representation. This technology focus data into a single presentation and allow for collaborative action among ITS-related information sources.

In this study, when applying the 'geological structure' content element of high school earth science I developed according to the 2015 curriculum to the STEAM program using a web-based expert system using 3D data of Google Earth and drones, the creative problem-solving ability of high school students, attitudes toward STEAM, and the results of this study are as follows. First, after applying the STEAM program, high school students' creative problem-solving ability showed meaningful results at the p<.001 level. Second, STEAM attitudes showed a significant value at the p<.001 level, confirming that they had a positive impact on high school students' attitudes towards STEAM. It was judged that web-based class activities using Google Earth and drones were useful for integrated thinking such as learners' sense of efficacy and value recognition for usefulness of knowledge. High school students' satisfaction with the STEAM program was 3.251, showing a slightly high average. It was confirmed that web-based class activities such as drones and Google Earth had a positive impact on learners' class satisfaction. However, it was interpreted that the lack of time for class activities limited the ability of the learners to increase their interest in class. The proposal of this research is as follows. First of all, in consideration of the production of presentation materials and practical training in the STEAM program, activities such as block time and advance instruction for class understanding before class are necessary. Secondly, in order to revitalize STEAM education in the high school curriculum, we judge that research on the development of various integrated education programs that can be applied to the high school grade system is necessary.

This study was conducted to analyze the forest status and deforestation area changes of the DMZ region in North Korea based on satellite images. Using growing and non-growing season's RapidEye satellite images, land cover of the North Korean DMZ was classified into stocking land(conifer, deciduous, mixed), deforested land(unstocked mountain, cultivated mountain, bare mountain), and non-forest areas. Deforestation rates in the Yeonan-baecheon, Beopdong-Pyeonggang, Heoyang-Geumgang and Tongcheon-Goseong district were calculated as 14.24%, 16.75%, 5.98%, and 16.63% respectively. Forest fire and land use change of forest were considered as the main causes of deforestation of DMZ. Changes in deforestation area were analyzed through Google Earth images. As a results, it was shown that the area of deforestation was on a decreasing trend. This study can be used as basic data for establishing inter-Korean border region's forest cooperation strategies by providing forest spatial information on the North Korea's DMZ.

In order to support wind power development in Jejudo, the island of winds, the wind resource database KIER-WindJeju has been established by meteor-statistical analysis on met-mast measurements of KIER. The analysis includes tower shading, exposure category, wind profile exponent for wind speed extrapolation to hub height of wind turbine, and correlation matrix between neighboring sites to assist choice of appropriate reference site for long-term correlation. KIER-WindJeju will be provided as an add-on of Google $Earth^{TM}$ and will be used as a guideline of future wind resource assessment in Jejudo.

This paper presents implementation of a system for effective visualizing flight information of aircraft using Google Earth. This system in order to use a detailed satellite image which provide from Google Earth used COM API. This system appeared the various flight information of the aircraft in the instrument panel using OpenGL and the aircraft flight condition is visible in the Google Earth Map. This research result used to flight evaluation and improvement. In future will be able to apply to flight software development.

지리정보시스템(GIS)은 경제발전, 환경보전, 도시계발 등에서 중요한 역할을 하고 있다. 지리정보시스템에서 빈도높게 측정되고 있는 것은 LiDAR(고정밀 항공 레이저 측량기술) 데이터로써 높은 위치정확도를 지니며, 데이터의 취득시 바로 지상좌표를 취득함으로써 좌표의 변환이 필요 없기 때문에 좀더 빠르게 데이터를 처리할 수 있는 장점을 가지고 있다. 본 연구에서는 이러한 LiDAR의 자료와 구글어스 등과 같이 2차원 영상을 획득한 경우, 3차원의 LiDAR 데이터를 2차원에 매핑시키는 방법을 연구하였다. 2차원 영상의 기준점을 정확하게 파악하는한 3차원의 LiDAR 데이터와 정확하게 일치하는 것으로 확인되었다.

항공기의 비행경로 시각화는 저고도 임무나 지형고도에 대한 위협을 해소하기 위하여 널리 사용되는 시스템이다. 하지만, 시스템을 구성하기 위하여 GPS와 방대한 지리정보를 구축해야하는 제약으로 인하여 게임 등의 저가형 시스템에 사용되기에는 불가능하다. 본 논문에서는 비행경로를 경제적으로 시각화하기 위한 오픈소스 기반의 DMM(Digital Moving Map) 시스템을 제한한다. 먼저 X-Plane에서 UDP를 통하여 비행정보를 전달받아 구글어스에서 시연 및 지형고도 정보를 DMM 시스템에 전달한다. DMM 시스템에서는 비행체의 고도와 현 위치의 지형고도를 매핑하여 ArcGIS의 MapServer를 통해 가져온 지도 정보상에 비행경로를 시각화한다. 시간간격에 다른 지형고도와 비행체의 고도 비교를 위하여 별도의 모니터링 화면을 제공한다. 본 논문의 결과물은 게임 및 연구 등의 목적으로 비행경로를 시각화하는 분야에 경제적인 도구로 사용될 수 있을 것이다.

Natural shifting of rivers has been disturbed by anthropological activities. Urbanization in Kathmandu has been encroached the natural floodplain of Bagmati and currently channeled by training walls. The study compares the change in shape of Dhobikhola, a small tributary using 1966 and 2014 satellite images. It has been found that the original shape is heavily changed over time at the beginning and end section of river under study. The river width is now fixed by training walls and roads along the banks. Using multiple data sets like satellite images and GIS analysis, these shifts can be easily detected to plan for management and restoration of physical and ecological behaviors of rivers.

According to the growing interest in the digital convergence throughout society, the convergence of creative and new forms is emerging recently in various fields. Research methods to explore the diversity of academic studies have been studied in the field of study. As one of these methods, research on electronic cultural atlas that has features of convergence studies is gradually spreading. In this paper, we examine existing electronic cultural atlas and then, compare and analyze them. In details, existing electronic cultural atlas are comparative analyzed on the basis of base map, interface, and function. Through the results of comparative analysis, the efficient production of electronic cultural atlas are examined.
