中文摘要 | 本文對準確地環繞在地球周圍的知名衛星,如美國的Landsat和Ikonos 及法國的Spot衛星之發展歷程作介紹,並就這些衛星的解像力、回歸周期、幅寬作有系統的比較評估,以啟科學家把握住這未來研究的利器,在研究領域中加入這技術,並呼籲政府重視這種光學技術,迎頭趕上,發展自己的軟硬體並培育這類的人才,必能節約許多浪費,縮短研究路徑,並快速準確地解決許多突發性災害的延生,使當局下決策解決問題時更加準確。 本文建議一般的大地研究,解像力三十公尺左右已足夠,使用美國的Landsat影像是經濟實惠的選擇,但研究農、林、漁、牧者,其解像力非30 至3公尺不可,研究者只有採用美國的Ikonos、印度的IRS或法國的Spot影像了,研究交通動線、城鎮規劃、軍事佈署者,非高解悉度不可,吾人只能採用Ikonos了。 |
英文摘要 | In the paper the technical development, resolution, period and the width of ground coverage of some famous satellites such as American Landsat, Ikonos and French Spot revolving around the earth in clock-like precision are introduced and evaluated to push the investigation and the use of the useful technics. In the paper the government of Taiwan is asked to focus attention on developing the optical technics, reaching forth unto those things which are before, developing the soft wares which are necessary for image interpretation and giving education to students so that much more budget will be saved, much more investigation fee can be shorten, many calamities can be avoided or solved in time and many accurate immediate decisions to solve calamities can be made by the government. The paper also suggests that the 30 meters resolution is enough for geotechnical investigation. The images taken from American Landsat are the excellent and economical choice for this kind of study. For the investigation of agriculture, forest, fishing and animal, 3 meters to 30 meters resolution are necessary. The images taken from American Ikonos , Indian IRS or French Spot are the helpful sources for the purpose. For the investigation of transportation system, city planning and military layout, the high resolution Ikonos is the only choice currently. |
