ArcGIS三大文件格式解析 Shape数据 shp存储几何要素的空间信息，即XY坐标 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 dbf存储地理数据的属性信息的dBase表 prj存储了文件的空间参考信息，如坐标系统等 shp.xml对元数据浏览后生成的xml元数据文件 sbn和sbx存储对shapefile的空间索引，加速空间数据的读取 Coverage数据 aat弧段属性表，记录弧段的起点和终点坐标信息 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 pat点属性表，记录lable点的坐标信息 tic控制点，用于配准地图的点 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 rrd保存影像金字塔信息索引，加速显示和漫游 dat属性信息 nit属性表定义文件 dir属性表路径管理文件，用于关联dat和nit Geodatabase数据 adf - ARC/INFO coverage data file agf - Atlas GIS native binary geodataset file ain - attribute index file aih - attribute index file alg - ER Mapper algorithm apr - ArcView Project File (ODB format) avl - legend template file (ODB format) avp - palette file (ODB format) ave - Avenue script avx - ArcView extension file (ODB format) ai - Adobe Illlustrator picture file bat - DOS batch file bil - image file (band interleaved by line) bip - image file (band interleaved by pixel) blw - world file for bil image bmp - Windows bitmap image file bpw - world file for bip or bmp images bsq - image file (band sequential) bqw - world file for bsq image c - C programming language source code filename cat - UNIX hyperhelp supporting file cgm - Computer Graphics Metafile cls - geocoding classification file cnt - help file contents dat - generic data file extension dat - INFO attribute file db - Object Database File (also ODB) dbf - dBASE tabular data file dbf - Shapefile attribute table file dbg - problem debug log file dcp - default codepage file dct - geocoding dictionary file dec - UNIX hyperhelp supporting file def - defaults file (North Arrows, Layout Templates, etc) (ODB format) dem - Digital Elevation Model file dgn - Design drawing file (Intergraph) dir - INFO directory manager file dlg - Digital Line Graph file dll - Windows Dynamic Link Library file doc - MS-Word, MS-Wordpad documen
