What is HDF format and how do I import an HDF-format file into Erdas Imagine?
HDF is a physical file format that allows storage of many different types of scientific data, including images, multidimensional data arrays, record oriented data, and point data. Follow this link to a step-by-step guide on HDF data import (e.g., Landsat ETM+). Note: Always check the most recent version of the software you are using, because software updates often include support for new file formats.
