ESRI GIS-Datei-Formate erläutert

ESRI-Formate und ihre Extensions, v.a. Shapefile (shape:

• .shp: The SHP file contains the geospatial data.
• .shx: The SHX file contains the index of the geospatial data.
• .dbf: The DBF file contains the attribute data in dBASE® format.
• .prj: The PRJ file contains the coordinate system information (optional). See PRJ.
• .avl: The AVL file contains the legend information (optional).
• .sbn/.sbx: The SBN and SBX files contain the spatial index of the geospatial data (optional).
• .xml: The XML file (*.shp.xml) contains the metadata describing the data set (optional).

Shapefile (.shp/.dbf/.shx)

Vektorformat mit Zusatzdateien. Von ArcView eingeführt.

Spezifikation: ESRI Whitepaper.

• myfile.shp: shapefile geometry data
• myfile.dbf: database data
• myfile.shx: shapefile index (internal)
• myfile.sbn: shapefile (internal)
• myfile.sbx: shapefile (internal)
• myfile.avl: ArcView legend
• myfile.rtf: data dictionary (rich text document)
• myfile.prj: projection file (coordinate reference system)

ArcExplorer kann ArcView-Projekte darstellen: .aep = ArcExporer-Projekt-Datei

ASCII Grid (.grd)

Refers to a specifc interchange format developed for ARC/INFO rasters in ASCII format. The format consists of a header that specifies the geographic domain and resolution, followed by the actual grid cell values. Usually the file extension is .asc, but recent versions of ESRI software also recognize the extension .grd.

Es können Werte von entweder integer (+/- 2 Milliarden) oder Float (+/- 10E38, 15 Digits) verwaltet werden.

Description:

The numbers of rows and columns are defined in the Grid NDX, NDY fields of the corresponding windows.

This format is used to export distributions in a ArcInfo compatible ASCII grid format. Cell Origin 0 or 0.5.

Syntax:

 ncols [number of columns]
 nrows [number of rows]
 xllcorner [x coordinate of lower left corner]
 yllcorner [y coordinate of lower left corner]
 cellsize  [cell size in meters]
 nodata_value [value which will be used if no data in grid cell; default is -9999]
 row 1 
 row 2
