What is ADF file?

ADF file extension is a raster data file format used by various software created by ESRI, such as ArcView, ArcInfo, and ArcGIS. Single ADF contains vector, spatial, and geographical attributes data.

ADF file grid

ADF files use binary grids in form of layers of rows and columns to store spatial information. Grids represent continuously changing geographical phenomena that are used as input data for statistical analysis of gathered data. Each grid cell has its own X and Y coordinate information and holds numerical value of given geographical attribute.

ADF file contains sets of binary grids stored in various files. Main grid can contain several raster layers that form a layer stack. Such solution in effect allow users to view different map overlays and perform statistical data analysis.

Some types of ADF files found in folders:

  • dblbnd.adf – stores grid boundary data,
  • hdr.adf – header containing information regarding cell resolution,
  • sta.adf – contains raster data statistics (minimum, maximum, mean, and standard deviation value),
  • prj.adf – stores projections and parameters,
  • w001001.adf – stores actual raster data.

We hope we helped you solve the problem with the ADF file. If you do not know where you can download the application from our list, click on the link (which is the name of the program) - you will find more information there on the location where to download the secure setup version of the required application.

What else may cause problems?

There can be more reasons which determine that you are not able to open the ADF file (apart from the lack of the proper application installed).

First - the ADF file may be incorrectly associated with the application installed to support it. In this case, you need to change this association by yourself. To do this, right-click on the ADF file that you want to edit, click "Open with" and then select the program from the list that you have installed. After this operation, the problems with opening the ADF file should be solved.

Second - the file you want to open can simply be damaged. Then, the best solution is to find a new version of given file, or download it again from the same source as before (maybe for some reason in the previous session the download of the ADF file has not been completed and it cannot be opened properly).
