在學校教授使用 GPS,已經事在必行了。不過,還有一些問題有待解決︰

  1. 不是每個學生都有 GPS 接收器的,怎辦?
  2. 我懂得的 GPS 應用,都是牽涉使用 GPX 格式的檔案;不過,不是所有軟件/硬件都兼容 GPX 格式的檔案,怎辦?
  3. 有些人使用有 GPS 功能的 PDA,它們大都附送 MapKing 軟件。這軟件所產生的檔案,怎樣可以成為在教學上容易使用的資料?

第三個問題,似乎有了初步的解決。謝謝 Kane 幫我在網上找到這個可以把 MapKing 軟件製成的 TR7 檔案(track log)轉換成 Google Earth 及 Google Maps 所能讀取的 KMZ 檔案。起碼如果擁有 GPS 功能的 PDA,也可以把行蹤記錄轉換成容易展示給其他人看的格式。

  1. Out of topic:
    Have you heard of twitter?
    It is now very popular in US.
    It may help you to take record when you are hiking/ travel.

    The application is web based, just like a weblog, but each entry allow very limited words. The key advantage makes it popular is that it support many kinds of send/ receive method, eg. SMS, email, IM. In other words, you can send/ receive data from the application anywhere anytime if your phone keep having signal.

    ps. guess who am i.
