進行一六邊形 ABCDEF 的閉合導線施測,示意圖如圖(一)所示,測得 各內角分別為 A  12030'25"、B  11929 '35"、C  11950 '25" 、 D  12010'15" 、 E  12140'20" 、 F  11819'30" ,已知 AB 的方 位角為 100°,經角度平差後,試問 CD 的方位角為何?(角度誤差採平 均分配的改正方式)

施行放樣工作時,有時因現場通視不良或因控制點無法補設如此緊密,而無法直接以控制點進行施測。 試問下列方式補設及放樣原則何者能提高點位放樣精度?

有一高層建築物高 412.53 公尺,以經緯儀檢核其垂直度,已知該儀器的直立軸誤差為 4" ,試問該建築 物檢核時橫向誤差最大值約為多少?

在都市計劃圖廓的檢核中,架站於控制點 P(N , E , Z)  (1100 , 1100 , 1145) ,後視於 O 點 (N , E , Z)  (1055 , 1145 , 1100) ,唯因後視控制的方位角已遺失,請協助利用現有的資料計算 PO 的方位角為何?

有一正五邊形的導線順時針方向依序編號為 ABCDE,經檢測獲知當 AB 邊之磁方向角為 S50°E,當時 的磁偏角是 2°W,試問 BC 邊的真方位角為何?

使用某天頂距式經緯儀對某控制點進行觀測,其縱角正鏡讀數為 35°12'35",倒鏡讀數為 324°47'15",利用 此儀器施測 A 點,獲知其正鏡讀數為 125°17'18",試問經指標差改正後,A 點的垂直角正確值應為多少?

甲、乙二人使用相同經緯儀觀測同一水平角,其觀測成果記錄如表(四),試求此水平角之最或是值中誤 差為何? 表(四) 人員 甲 乙 觀測 60°25'24" 60°25'28" 成果 60°25'30" 60°25'36" 60°25'32"

於 AB 二已知點間實施附合水準測量,施測結果如表(三)。已知由 A 點測至 B 點時的閉合差為 0.008 m, 而 TP 的前視值因作業疏忽而遺漏,試將 TP 應有的觀測值填入後並完成各點的平差改正後,試求 C 點 的改正後高程值應為多少?(假設觀測時前後視的距離皆相等且閉合差採平均分配的方式進行改正) 2 2 表(三) 測站 後視 間視 前視 改正值 改正後高程 備註 A 1.152 28.375 已知 TP 1.425 2.253 ? 1 TP 1.296 2 C 1.215 TP3 2.152 2.284 B 2.273 26.007 已知

A B C AC 正確的平距為 225.150 m,且 B、C 的高差為 4.200 m,試問卷尺正確之長度應為多少?
