Years ago I ran into a tool built by the Remote Sensing/GIS lab and Utah State University. I recently stumbled onto the tool once again and immediately thought of sharing the tool with you folks.
The website states, “This website provides three tools that create ERDAS Imagine TM spatial models (.gmd format). Each tool creates a different .gmd file providing a slightly different approach to standardization. These tools are designed for Landsat 5 TM and Landsat 7 ETM+ scenes and require, as input, the header file (*.h1) accompanying NLAPS formatted imagery from the USGS at Eros Data Center.”
It offers,
- DN-to-Reflectance Conversion
- COST Atmospheric Correction
- COST without Tau (Dark Object Subtraction) Atmospheric Correction
Check it out and have fun...
