野外采样数字装图法原理

数字装图法的基本思想,是在开阔地区用电子速测仪直接测定地形点的坐标,而在半开阔地区和隐蔽地区则用电子速测仪测定少量明显地物点作骨干点,再用勘丈记录计算法和勘丈绘图数字化法,将一块一块的数字图形装进图幅中。

ASSEMBLE METHOD PRINCIPLE WITH DIGITAL GRAPH ON FIELD SAMPLING

Assemble method with digital graph for the field sampling is to delermine directly coordinates of terrain points using total stations in the open area, but to delermine only obvious a few topograph points using total stations for mainstay points in the half open area and in the conceal area then one by one digital graph be fitted together the sheet to use measure record compute method and measure draw digitigation method.
