杭州交通信息网z轴对刀仪怎么使用:如何用MapBasic编程使坐标自动连成线，面啊？
来源：百度文库 编辑：杭州交通信息网 时间：2024/05/06 07:46:30
我有txt文本的坐标数据，存的方式是属性，点号，坐标
但是我不知道怎样把坐标点在Mapinfo下自动生成线、面，包括道路点等
我不太会用MapBasic，希望高手能给出具体程序。

读出文本文件中的坐标值，然后用CreateLine( )函数生成各线对象。
语法
CreateLine( x1 , y1, x2 , y2 )
X1是单精度值，代表线起点的x轴位置（如经度）
y1是单精度值，代表线起点的y轴位置（如纬度）
X2是单精度值，代表线终点的x轴位置（如经度）
Y2是单精度值，代表线终点的y轴位置（如纬度）
返回值－Object
描述
CreateLine( )函数返回代表一条线的物体值X、y参数使用MapBasic正在默认使用的坐标系统。MapBasic使用经纬度坐标系统，通过Set CoordSys语句能够重新设置MapBasic来使用一个不同的坐标系统。注意MapBasic的坐标系统独立于任何map窗口的坐标系统。通过CreateLine( )函数可以创建一个分配给物体变量的线，储存在已有表的一行中（通过update刷新语句），或者插入到新的一行表中（通过插入语句）
注意：在一个布局窗口创建一个物体前，必须先声明Set CoordSys Layout语句
