About this app
Imaging 3D relief from 2D contours has long been a difficult skill for geography students when learning map reading. This AR tool helps students visualize various 3D relief features represented by contour lines. 地理科學生學習地圖閱讀技能時，其中一個經常遇到的難題是怎樣將平面的等高線想像成立體的地勢。本AR工具有助學生培養立體概念，學懂怎樣將各種平面的等高線地圖形象化，成為立體的地勢模型。
