ArcGIS常用文件格式

遥感影像数据

如果是原始的卫星影像,有可能是磁带存储的二进制格式,即*.bin。

如果是从地面站买到的数据,多半是Geo-Tiff的格式,即带有坐标的Tiff图。 如果是已经格式调整完成,等待分类、分析的影像,一般为*.img格式 Shapefile数据

1. shp存储几何要素的空间信息,即XY坐标 Shapefile文件用于描述几何体对象:点,折线与多边形。

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

7. Shapefile无法存储拓扑信息。在ESRI的文件格式中,ArcInfo 的Coverage、以及

Personal/File/Enterprise地理数据库,能够保存地理要素的拓扑信息。

8. shp文件或.dbf文件最大的体积不能够超过2 GB(或2位)。也就是说,一个

shapefile最多只能够存储七千万个点坐标。

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 Geodatabase数据
