Copy information between ENVI header files

It often becomes necessary to copy information or metadata in ENVI header files during remote sensing data processing. IDL is a good tool to write code for doing this, as it is integrated with ENVI and recognises some of the fields in ENVI format HDR files immediately. Here is another solution for copying information from ENVI HDR files using an open-source environment.

The header files (.hdr) of ENVI files are text files which contain the size of the file (pixels and lines) geospatial information and other meta data such as wavelengths, data units etc.,

Not all programs are aware of all items in then header file and some may become lost during processing. ARSF-DAN have made a script available which can copy attributes from one header to another. The script can be downloaded from https://github.com/pmlrsg/arsf_tools and is run using:

To show the available fields the following script (also from the arsf_tools repo) can be used:

About WQ

I received my PhD (2013) in Remote Sensing, Earth and Space Science at the Dept. of Aerospace Engineering Sciences, University of Colorado, Boulder, USA, under a Fulbright fellowship. Currently, I'm an Assistant Professor in the Dept. of Space Science at Institute of Space Technology (IST), Islamabad, Pakistan, where I have been a founding member of the Geospatial Research & Education Lab (GREL). My general expertise is in Remote Sensing where I have worked with various remote sensing datasets through my career, while for my PhD thesis I specifically worked on Remote Sensing using SAR (Synthetic Aperture Radar) and Oceanography, working extensively on development of techniques to measure ocean surface currents from space-borne SAR intensity images and interferometric data. My research interests are: Remote sensing, Synthetic Aperture Radar (SAR) imagery and interferometric data processing & analysis, Visible/Infrared/High-resolution satellite image processing & analysis, Oceanography, Earth system study and modelling, LIDAR data processing and analysis, Scientific programming. I am a reviewer for IEEE Transactions on Geoscience & Remote Sensing, Forest Ecosystems, GIScience & Remote Sensing, Journal of African Earth Sciences, and Italian Journal of Agronomy. I am an alumnus of Pakistan National Physics Talent Contest (NPTC), an alumnus of the Lindau Nobel Laureate Meetings, a Fulbright alumnus, and the Pakistan National Point of Contact for Space Generation Advisory Council (SGAC). I was an invited speaker at the TEDxIslamabad event held in Nov., 2014. I've served as mentor in the NASA International Space App Challenge Islamabad events in April 2015 and April 2016.
