将数据写入KML文件

将CPoint结构写入KML文件中，使用文件流提高速度。

1、需包含” fstream”文件

#include

2、例子：

void WriteToKML(char *filename,vector sourcedata)

{

ofstream o_file;

o_file.open(filename,ios::trunc|ios::binary);

o_file<<"\r\n";

o_file<<"\r\n";

o_file<<"\r\n";

o_file<<"";

o_file<

o_file<<"\r\n";

o_file<<"\r\n";

o_file<<"\r\n";

o_file<<"Flight Path\r\n";

o_file<<"Flight Route path\r\n";

o_file<<"#yellowLine\r\n";

o_file<<"1";

o_file<<"0";

o_file<<"\r\n";

o_file<<"1\r\n";

o_file<<"1\r\n";

o_file<<"absolute\r\n";

o_file<<"\r\n";

int numb = sourcedata.size();

int count;

for (count=0;count < numb;count++)

{

o_file<

o_file<

}

o_file<<"\r\n \r\n \r\n";

o_file<<"\r\n ";

o_file.close();

}
