MapInfo之格式说明（转载）

1、数据文件

下列文件组合起来描述一个图层:

.tab          

    描述MapInfo表结构,说明数据文件格式 文本

.dat(.mdb/.dbf/.txt/.xls/.wks) 

    表格数据   二进制

.map                                            

    图形对象(无图形，对象则不存在) 二进制

.id                                                

   连接数据和地图对象的参照文件(无对象则不存在) 二进制

.ind                                              

   索引文件,查帐地图对象 二进制

 

2.描述地图文件有两种

.gst                 文本格式，tab文件的集合,不能存入数据库

.mdf                XML格式，包含各图层的信息，可以存入数据库 （*！）
