Field Instrumentation for Environmental Remote Sensing

许多遥感是基于这样一个原则，即通过检查物质在各种电磁波长下的辐射特性可以得到重要的信息。然而，学生很少有机会直接测量这些辐射特性。该计划将为学生提供最先进的遥感和测绘仪器（如辐射计、数码相机和GPS接收器）的实践经验。赋予学生使用仪器的经验和技能应该成为本科地理课程的一个更基本的部分。特别是实地体验，使地理专业学生和非专业学生都能将课堂理论应用于现实世界的现象。此外，这些经验和技能使学生能够在学术界之外找到工作，并提高他们进入研究生院的记录。美国国家地理信息与分析中心（NCGIA）已经开始为本科阶段的理想遥感课程制定指导方针。一项建议是开设遥感现场技术课程。特别是，NCGIA建议允许学生收集现场数据，校准辐射计，并评估遥感观测中的误差。没有适当的工具，这些任务是不可能完成的。这个i - ip项目将允许在印第安纳大学的几门课程和环境中向各种学生教授遥感实地技术。该项目的结果将提交给专业期刊和NCGIA，作为本科生遥感实地经验的模型。

Much of remote sensing is based on the principle that important information can be derived by examining the radiative characteristics of matter at a variety of electromagnetic wavelengths. It is rare, however, for students to have the opportunity to measure these radiative characteristics directly. This proposal would give students hands-on experience with state-of-the art remote sensing and mapping instrumentation (e.g., radiometers, digital cameras, and GPS receivers). Giving students experience and skills with instrumentation should become a more fundamental part of the undergraduate geography curriculum. Field experiences, in particular, allow both geography major and non-majors to apply classroom theory to real-world phenomena. In addition, these experiences and skills allow students to obtain jobs outside academia and to enhance their records for entry into graduate school. The National Center for Geographic Information and Analysis (NCGIA) has begun to establish guidelines for an ideal remote sensing curriculum at the undergraduate level. One recommendation has been to teach a Remote Sensing Field Techniques course. In particular, the NCGIA recommendation is to allow students to collect field data, calibrate radiometers, and to assess errors in remote sensing observations. Without appropriate instrumentation, these tasks are impossible. This ILI-IP project would allow remote sensing field techniques to be taught to a variety of students in several courses and contexts at Indiana University. The results from this project will be submitted to professional journals and NCGIA as a model for undergraduate field experience in remote sensing.
