ArcGIS地理信息系统三大文件格式解析

Shape数据

1. shp存储几何要素的空间信息，即XY坐标

2. shx存储了有关.shp存储的索引信息，即shp中空间数据的存储方式，XY坐标的输

入点在哪里，有多少XY坐标对等信息

3. dbf存储地理数据的属性信息的dBase表

4. prj存储了文件的空间参考信息，如坐标系统等

5. 对元数据浏览后生成的xml元数据文件

6. sbn和sbx存储对shapefile的空间索引，加速空间数据的读取

Coverage数据

1. aat弧段属性表，记录弧段的起点和终点坐标信息

2. adf为coverage格式，包括、、、、、、、

都记录了坐标信息，、为索引文件和、为属性文

件

3. pat点属性表，记录lable点的坐标信息

4. tic控制点，用于配准地图的点

5. aux保存栅格文件自身不能保存的辅助信息，包括彩色地图信息，直方图或表格，

坐标系统，变换信息，投影信息

6. rrd保存影像金字塔信息索引，加速显示和漫游

7. dat属性信息

8. nit属性表定义文件

9. dir属性表路径管理文件，用于关联dat和nit
