Field Instrumentation for Environmental Remote Sensing

许多遥感工作所依据的原则是，通过研究物质在各种电磁波长下的辐射特性，可以获得重要的信息。然而，学生很少有机会直接测量这些辐射特性。这一建议将使学生亲身体验最先进的遥感和绘图仪器（例如，辐射计、数码相机和GPS接收器）。让学生的经验和技能与仪器应成为本科地理课程的一个更基本的组成部分。实地经验，特别是允许地理专业和非专业的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获得学术界以外的工作，并提高他们进入研究生院的记录。 国家地理信息和分析中心（NCGIA）已开始为本科生一级理想的遥感课程制定指导方针。一项建议是教授遥感实地技术课程。特别是，NCGIA建议允许学生收集实地数据，校准辐射计，并评估遥感观测中的误差。如果没有适当的仪器，这些任务是不可能的。这一ILI-IP项目将使印第安纳州大学能够在若干课程和背景下向各种学生教授遥感实地技术。该项目的成果将提交给专业期刊和国家遥感和信息咨询小组，作为大学生遥感实地经验的范本。

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.
