Convert GDBTABLX to ADF

Understanding gdbtablx and adf file formats

gdbtablx files are part of the Esri File Geodatabase (GDB) structure, specifically used to store spatial index and table information for geospatial datasets. These files are not standalone data files but work in conjunction with other GDB components to manage and index spatial data efficiently.

ADF (Arc/Info Binary Grid) files are a raster data format developed by Esri for storing gridded spatial data, such as digital elevation models or other raster datasets. The ADF format is used in ArcInfo Workstation and is recognized by many GIS applications for raster data processing.

How to convert gdbtablx to adf

Direct conversion from gdbtablx to adf is not possible, as gdbtablx is not a data file but a supporting index file within a File Geodatabase. To create an ADF raster from data stored in a File Geodatabase, you need to export the relevant raster or feature class from the geodatabase to the ADF format using GIS software.

Recommended software for conversion

The best software for this process is Esri ArcGIS Pro or ArcMap. These applications allow you to export raster datasets from a File Geodatabase to the ADF (Arc/Info Binary Grid) format. Here’s how you can do it:

• Open your File Geodatabase in ArcGIS Pro or ArcMap.
• Locate the raster dataset you wish to export (not the gdbtablx file itself).
• Go to ArcToolbox → Conversion Tools → To Raster → Raster to Other Format.
• Select the output format as GRID (which creates ADF files).
• Specify the output location and run the tool.

For open-source alternatives, GDAL (Geospatial Data Abstraction Library) can also be used to convert raster data from a File Geodatabase to the ADF format using the gdal_translate command, provided the GDAL build supports FileGDB and ADF formats.

Summary

While you cannot convert a gdbtablx file directly to adf, you can export raster data from a File Geodatabase to the ADF format using ArcGIS or GDAL. Always work with the actual raster or feature class, not the index files like gdbtablx.
