Upgrading the Undergraduate Experience with the Earth Resources Data Analysis System (ERDAS)

滑石大学正在利用地球资源数据分析系统(ERDAS)扩大、更新和加强针对地理和环境研究系专业和辅修专业的本科课程。这一功能强大但价格适中的系统包括一个基于微型计算机的(IBM PC/AT增强型)工作站，支持外围硬件和支持软件。学生们正在学习如何生成数字数据库(使用数字化平板电脑和视频数字化仪)，以便在评估自然资源时分析空间分布的现象(使用图像处理、地理信息系统模块和地形模块)。还提供了使用彩色硬拷贝模块以制图准确的格式绘制数据的说明。

The undergraduate program for majors and minors in the Department of Geography and Environmental Studies is being expanded, updated and strengthened at Slippery Rock University through the utilization of the Earth Resources Data Analysis System (ERDAS). This powerful, yet moderately priced system includes a microcomputer-based (IBM PC/AT- enhanced) work station which supports peripheral hardware and supporting software. Students are learning how to generate digital data bases (using a Digitizing Tablet and Video Digitizer) in order to analyze spatially distributed phenomena (with Image Processing, Geographic Information System Module and Topographic Module) in evaluating natural resources. Also provided is instruction in data plotting in a cartographically accurate format using the Color Hardcopy Module.
