ArcGIS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
