2.盡可能放大所需的地形範圍，使用google Maps的測距工具測量盡可能長的距離(鼠標右鍵-測量距離-然後選擇第二個左鍵)，使用截圖軟件捕捉所需的範圍並保存為JPG格式。

3.打開CAD地形圖，輸入ATTACH命令，將上壹步保存的JPG影像加載到CAD中，任意比例尺。選擇加載的圖片，
輸入SC命令，點擊鼠標左鍵選擇基點-r(參考)-指定參考長度(選擇圖中兩點測量距離)-指定新長度(此處輸入圖中測量長度為2560m)，即完成圖片尺寸到CAD圖中尺寸的縮放。

4.找壹個對應點(比如兩條河的交匯點，道路，建築物的拐角)，把圖片移到CAD矢量圖上。

5.此時，圖片可能會疊加在CAD圖上，導致無法看到矢量圖。選擇圖片並輸入DR command-B，將圖片放在底部。

6.根據兩棟建築的位置進行微調，完成效果圖。
