Convert MPK to ADF

Understanding MPK and ADF file formats

MPK files are typically associated with ArcGIS Map Packages, which are used to bundle maps, data, and resources for sharing within Esri's ArcGIS platform. These files are proprietary and designed for geographic information system (GIS) workflows.

ADF files, on the other hand, are Arc/Info Binary Grid files, a raster data format used by Esri software for storing spatial data such as digital elevation models or other gridded datasets. ADF files are part of a folder structure representing a single raster dataset.

Why convert MPK to ADF?

Converting an MPK to ADF is typically required when you need to extract raster data from a map package for use in other GIS applications or workflows that require the binary grid format.

How to convert MPK to ADF

Direct conversion from MPK to ADF is not straightforward, as MPK is a container format. The process involves extracting the contents of the MPK file and then exporting the relevant raster layers to the ADF format.

1. Extract the MPK file: Open the MPK file in ArcGIS Desktop (ArcMap or ArcGIS Pro). MPK files can be opened directly by double-clicking or using File → Open.
2. Identify the raster layer: In the map contents, locate the raster dataset you wish to export.
3. Export to ADF: Right-click the raster layer and select Data → Export Data. In the export dialog, choose the output format as ArcInfo Binary Grid (ADF). Specify the output location and filename, then click OK to export.

Best software for MPK to ADF conversion

The most reliable software for this conversion is Esri ArcGIS Desktop (ArcMap or ArcGIS Pro). These applications natively support both MPK and ADF formats and provide robust tools for data extraction and export.

• ArcGIS Pro: Use Share → Package → Unpack to open MPK, then Data → Export Raster to save as ADF.
• ArcMap: Open MPK, right-click raster layer, and use Data → Export Data to export as ADF.

There are no reliable online converters for this workflow due to the proprietary nature of MPK files and the complexity of GIS data.

Summary

To convert MPK to ADF, use ArcGIS Desktop to extract and export raster data. This ensures data integrity and compatibility with GIS workflows.
