摘要
本文介绍的多功能导线计算程序,是根据林业勘测调查特点,在PC-1500类型计算机上,设计编写的适于罗盘仪、经纬仪的多功能导线及面积计算应用程序。程序主要功能有,根据一定外业资料,可分别打印出罗盘仪闭合导线多边形各边的水平距、方位角、导线全长相对闭合差、各点坐标值和多边形面积;经纬仪闭合、附合导线的角闭合差、允许角闭合差、方位角、坐标增量闭合差、导线全长相对闭合差、各点坐标,及坐标中的最大值,最小值和多边形面积;计算两个点的交导线。读程序运行环境为BASIC语言,并采用了一定的编程技巧,结构紧凑。输入数据方便,输出结果齐全。功能强、效率高,易于掌握和使用。
The traverse calculation program of multiple functions, intrddued in this paper, is programed with PC-1500 computer based on the characteristics in forest survey. This program is suitable for compass and transit in the calculations of traverse of multiple functions and area.The main functions of the program are :1) to paint polygan of closed traverse, horizontal distance of each side, azimuth angle, relative closed error of whole traverse, coordinate value of each point and area of polygon based on the field data of compass. 2) For transit, the program can print the closed error of angle of closed and annexed traverse, permitted closed error of angle ,azimuth angle, closed error of coordiuate inerement, rel-ative closed error of whole traverse, coordinate of each point and the m-aximum and minimum values in the coordinate, and the area of polygon. 3) To oalculate the sub-traverse of tow peiats. This program is aun with BASIC language and easy to learn and use for its features of easy of lata input, complate output of reaults,high funetions and high efficiency.
