運用 Google Earth 製作地形剖面圖

中央研究院計算中心的同仁利用Google Earth API寫了一個小工具GE Profile,利用該工具便可以在Google Earth 製作地形剖面圖, 這個軟體可以自「GIS應用支援工具集」網頁(第37項)中免費下載。

啟動該軟體之後,使用者便可以在 Google Earth 上利用新增路徑方式畫出一條剖面線,GE_Profile小工具便可繪製出地形剖面。

同時還可以利用 Google Earth 3D 地形顯示及旋轉瀏覽功能,呈現地形剖面實景。

    […] Google Earth 5.2版針對路徑資料新增一個"顯示高度剖面"的功能,這個功能中研院GIS小組在2009年時,就有開發一個類似的外掛小工具,讓使用者可以運用 Google Earth 製作地形剖面圖,現在Google Earth把這個功能內建,使用起來就更方便了。路徑資料除了可以是從GPS設備(例如PND、GPS  Logger)下載之外,使用者也可以利用新增路徑功能,手動繪製而得。也就是說,你可以針對地球上的任何地方,在上面畫一條線,直線、曲線都可以,Google Earth就會幫你把沿著這條線的地形起伏狀況繪製成剖面圖給你參考,更神奇的是,你可以在剖面圖移動,在地表上會對應顯示一個紅色的箭頭,標示出對應的地點,並點是該點的海拔高度、坡度等訊息。也就是說,透過這個高度剖面的功能,你可以很容易地查到一個地點的高度、坡度以及鄰近的地形走勢,這對於地理科教學非常有用,老師可以利用來解釋台地、河階、順向坡等地形特徵,一般大眾則可以查詢住家附近或山坡地建案的坡度是多少(臺灣法規規定坡度逾55%禁止開發),可以誇大地說是現代公民都應該學習的功能。 […]

    Whats up are using WordPress for your site platform? I’m new to the blog world but I’m trying to get started and create my own. Do you require any html coding expertise to make your own blog? Any help would be greatly appreciated!

    Howdy would you mind sharing which blog platform you’re working with? I’m looking to start my own blog soon but I’m having a tough time choosing between BlogEngine/Wordpress/B2evolution and Drupal. The reason I ask is because your design and style seems different then most blogs and I’m looking for something completely unique. P.S My apologies for being off-topic but I had to ask!

    Thank you for this article. I’d also like to express that it can often be hard while you are in school and merely starting out to create a long credit ranking. There are many individuals who are just trying to live and have a lengthy or beneficial credit history is often a difficult thing to have.

    of course like your web site however you need to take a look at the spelling on several of your posts. Several of them are rife with spelling problems and I find it very bothersome to tell the truth on the other hand I’ll definitely come back again.
