MapInfo数据字典、文件结构说明

数据文件
下列文件组合起来描述一个图层:

后缀名
 描述
 格式
 
.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

.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,查找地图对象
 二进制
 

 

描述地图的文件有两种:

.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,推荐使用
