閉合トラバース測量の計算手順｜内角調整・方向角・閉合差を初心者向けに解説

This video explains closed traverse surveying for beginners. Closed traverse surveying is a method of surveying by sequentially measuring points and returning to the starting point. This video explains the concepts of "azimuth, latitude, and longitude," which are commonly found in textbooks, by replacing them with "X and Y coordinates" and "direction angle," which are used in actual construction sites. The main contents are as follows: 00:00 Introduction 01:51 What is Closed Traverse Surveying? 07:56 6 Steps to Calculating Closed Traverse Surveying 09:41 Step 1: Confirming and Adjusting Interior Angles 12:43 Understanding Direction Angles 16:16 Calculating Movement in X and Y Directions 19:00 Confirming Closure Difference and Closure Ratio 22:16 Error Adjustment 23:47 Determining XY Coordinates 26:29 Summary 28:07 Channel, Blog, and Note Introduction We hope this will be helpful for those just starting to learn surveying or those who struggle with traverse calculations. ▼More detailed explanations are available on our blog. https://pooloyolo.blog/surveying/clos... ▼note: Useful PDF manuals for on-site work https://note.com/kensetunavi_55 ▼Various regulations concerning control point surveying https://www.gsi.go.jp/keikaku/keikaku... ▼Related videos and recommended articles ・[Surveying] How to calculate elevation using a Total Station https://pooloyolo.blog/surveying/try-le veling-at-a-total-station/ • [For Beginners] How to Perform 2-Pair Rotational Angle Measurement https://pooloyolo.blog/surveying/hori... • Construction Survey (How to Create a KBM) for Beginners https://pooloyolo.blog/surveying/kbm/ • Let's Calculate Coordinates | Field Survey Calculation from Angle and Distance https://pooloyolo.blog/surveying/trav... #ClosedTraverseSurvey #TraverseSurvey #Surveying #CivilEngineeringConstructionManagement #PlaneRectangularCoordinates
