ArcGIS三大文件格式解析

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.shp.xml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lab.adf、arc.adf、sec.adf、pal.adf、cnt.adf、tic.adf、lnk.adf、

bnd.adf都记录了坐标信息，arx.adf、pax.adf为索引文件和pat.adf、aat.adf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
