Development of an educational fieldwork-supported system based on Web-GIS and its application for environmental education

本研究的目标如下：1）在金泽市进行温度和湿度观测，2）开发可用于户外活动的实用环境教育支持系统，（3）使用我们的观察数据对一个类的执行情况进行了研究，结果如下：1）在金泽市进行温度和湿度观测在市中心的一所小学的仪器室中设置了一个数据记录器，每隔10分钟观测一次温度和湿度。观测点数量为45个。这些数据经过编辑，可用作环境教育课程的教材。2）户外活动用Web-GIS系统的开发利用全球定位系统（GPS）确定观测位置。该系统由一个环境信息数据库组成，学生可以从中获得与位置坐标所示地点有关的环境信息。对系统进行了改进，使其即使在现场作业时无法使用互联网浏览器访问数据，也能以独立模式使用。3）使用观测数据的课程实施利用观测数据向石川县立小松商业高中的学生们介绍了金泽市的热环境。学生们了解了金泽市的热岛现象。然后，我们开始在小松市进行地面气温观测，就像在金泽市一样。小松是我们研究地点中仅次于金泽的第二大城市，观察地点是由学生推荐的。

The objectives of this research are as follows : 1)the execution of a temperature and humidity observation in Kanazawa City, 2)the development of a practical environmental education support system that can be used for outdoor activities, and 3)the execution of a class using our observation data.The results of this research were as follows.1)Execution of a temperature and humidity observation in Kanazawa CityA data logger was set up in the instrument shelter of an elementary school in the center of the city, and the temperature and humidity were observed at 10-minute intervals. The number of observation points was 45. The data were edited so they could be used as teaching material in the environmental education course. An atmospheric observation was executed by using a sky-radio meter.2)Development of a Web-GIS system for outdoors activitiesAn observation position was identified by using a Global Positioning System (GPS). The system consisted of an environmental information database from which students obtained environmental information related to the place indicated by the positional coordinates. The system was improved so that it could be used in a stand-alone mode even when an Internet browser could not be used to access the data during field work.3)Execution of a class using our observation dataWe explained the heat environment of Kanazawa City using our observational data to students at Ishikawa Prefectural Komatsu Commercial High School. The students learned about the heat island phenomena in Kanazawa City. We then started to conduct ground-air temperature observations at Komatsu City, as in Kanazawa City. Komatsu is the second-largest city after Kanazawa in our study site, and the locations for the observation were recommended by the students.
