GIS课例二科罗拉多的风力发电站选址20111120
这也是ArcLessons上的一个GIS课例,原文地址见:

我想这不应该是个课例而应该是个我们曾经热衷的研究性学习。
这个项目仍然面对高中学生---我想高中学生已经足够完成这个项目的,要求学生利用老师给的基本数据,再根据以下限定的条件找到在科罗拉多的风力发电站的最佳位置:
Problem:
Hearing about your GIS skills, the State of Colorado Office of Renewable Energy has contracted with you to determine the most suitable sites for planning new wind energy farms in Colorado. The sites must be:
1. In an area where the Wind Power Class is at least 4, which is “good” or better in terms of wind farm resource potential.
2. No further than 5 miles from a highway, so that maintenance crews can more easily access the wind turbines.
3. No further than 50 miles from a city containing at least 25,000 people, to ensure a nearby target market.
4. Not on Federal Land (national parks, forests, grasslands, and so on).
5. On land that meets criteria 1-4 that is also at least 1 square kilometer in size, large enough for a wind farm.
问题本身应该是不难的,难的是数据的获取和选值标准的制定,作为一个学生研究项目,我想这两项任务的挑战更大。
我不知道真正的美国中学是如何教学生学习3S技术的,不知道他们时候真地如这个课例一样,完全是“做中学”。但以我们的教学来看,完全脱离实践动手的3S教学无疑是效果不佳的。
