災害潛勢地圖網站主要提供防災規劃及民眾使用，為了讓使用者更能瞭解什麼是災害潛勢，以達到架設網站之目的，在網站的設計不但要吸引民眾，內容也要淺顯易懂，在操作上更為順手、瀏覽更為方便。因此，在潛勢地圖網站架構上，導入使用者經驗的開發流程設計，透過使用者需求訪談，整理需求，逐一建立以使用者所需為導向之災害潛勢地圖網站，經過一年以上的營運時間，透過易用性評估（System Usability Scale，SUS）來了解改版後網站成效，是否真正符合使用者需求。根據易用性評估結果，本網站在系統易用性測試中，SUS的接受等級（ACCEPTABLE RANGES）評分得到可接受（ACCEPTABLE）的等級、以及形容評級（ADJECTIVE RATINGS）為：好的（GOOD）等級。另外，在使用者體驗感受分析結果，三個任務測試分別提升了24.7%、19.3%及19.3%，最後將其回饋建議作為網站調整之參考。

The disaster potential map website has been constructed primarily for disaster prevention planning and for the use of the general public. Because the purpose of constructing this website was to help users better understand disaster potential, not only should the website design be attractive, but also the content should be simple and easy to comprehend. Overall, the website should be easy to operate and convenient to browse. Therefore, user experience was incorporated into the website design and development process. Accordingly, users were interviewed regarding their needs, thereby establishing a user-oriented disaster potential map website. After more than one year of operation, system usability scale was employed to evaluate whether the revised website effectively met users' needs. The evaluation results showed that the disaster potential map website achieved an acceptable level in the acceptability range and an adjective rating of good. In addition, the analysis of users' experience and perceptions revealed that the website usability for three tasks increased by 24.7%, 19.3%, and 19.3%. The users' feedback and suggestions were used as references for website adjustment.
