This file is saved in a binary format, which requires a specific program to read its contents.

Definition

Internal raster data format used by ESRI products such as ArcGIS, ArcView, and ArcInfo Workstation; stores spatial data as a binary grid (rows and columns of cells) and is one of several ADF files that together comprise the total grid; used to represent geographical or other spatial objects such as maps and map features.

More Information

An ArcInfo binary grid can contain multiple raster layers, forming a layer stack. This can be used to overlay different views on surfaces and perform statistical analysis on the spatial data.

ADF files can store metadata about the raster set or actual raster data. When you create a binary grid, the files named dblbnd.adf, hdr.adf, sta.adf, vat.adf, and w001001x.adf provide metadata about the raster grid, while the file w001001.adf contains the actual raster data. These files are typically separated out into their own folder so that they are easy to manage as an entire grid coverage set.
