The Application Research of Geography Teaching with ERDAS Software in the Middle School

摘要

With the development of satellite remote sensing technology, remote sensing image has become an important data source gradually for modern Geo-science analysis and research. Among the massive Multi-source Remote Sensing data, the processing of Remote Sensing image is considered as a crucial mean to achieve image data mining and knowledge discovery. Therefore, ERDAS software will play a significant role in the geographical teaching and reforms, with its advantage as an important tool and platform for remote sensing data analysis. Based on the introduction of the characteristics of ERDAS software, the specific application of ERDAS in middle school geography class is also proposed, concluding mobilizing students' subjective initiative in learning, improving teaching effect, establishing an open geography class, and improving students' foreign language level and operational ability. Then, the key methods of images preprocessing are introduced in the application of ERDAS software. Finally, practical problems of ERDAS software applications are analyzed. In conclusion, the present study provides an important reference value for improving the quality of geography teaching in junior high school.
