A topographic survey is a detailed mapping technique used to measure and record the physical features of a land area. It involves the use of specialized surveying equipment, such as electronic total station or GNSS-RTK to accurately determine both the horizontal coordinates and elevations of natural and man-made features.

 

This survey provides valuable information for various purposes, such as land development, infrastructure planning, engineering design, and environmental assessment. The collected data is typically presented through topographic maps, contour lines, and digital elevation models, enabling precise analysis and decision-making for land-related projects.

地形測量是一種精確製圖技術，用於測量和記錄某片土地地區的實際地貌特徵。它涉及使用專門的測量設備，如電子全站儀或全球衛星定位系統來準確記錄自然和人工地面特徵的水平坐標和高程。

這種測量為各種用途提供了有價值的信息，如土地開發、基礎設施規劃、工程設計和環境評估。所收集的數據通常以地形圖、等高線和數字高程模型的形式呈現，從而協助土地相關項目的精確分析和決策。
