We are planning to add the Landsat 8 reader to ENVI with the third service pack to version 5.0. We currently expect that service pack to be available later this spring, before Landsat 8 data become generally available. Peg Exelis VIS

I was wondering if functions such as TMCAL_DOIT will be modified, and if so, is there any existing documentation? I have code to update, and this would be very helpful.

TMCAL_DOIT was not updated and probably will not work with Landsat 8 data at this time. In ENVI SP2 there is a generic calibration tool for all types of data but the routine has not yet been exposed. The plans for exposing this routine is scheduled for ENVI 5.1.

When will this be patch be availble? L8 is currently 'generally available' ... Jim

Hello, I just downloaded and installed ENVI 5 SP3 and successfully opened a Landsat 8 image in ENVI 5. HOWEVER, when I tried to open the mtl.txt file in ENVI Classic, it didn't work. Did Exelis not implement this in the Classic version or is it supposed to work? I used a 'very old' Landsat 8 image for my testing that I downloaded very early when sample L8 imagery was available, so maybe the mtl.txt file has changed slightly causing some trouble? Just in case, it's copied below. I sure hope opening the L8 files will work in the Classic version too.

The Landsat 8 reader and calibration tool are only available in ENVI 5. For details of what went into ENVI 5 please refer to: http://www.exelisvis.com/...-Service-Pack-3.aspx

It'd be great if this could be integrated in the Classic version too. If not by Exelis, hopefully someone can write a sav file for it. :) Mike

I understand that Feature Extraction was limited to only the GUI. I was disappointed when the bad Line of Site function in Classic was not fixed because the function worked in GUI. And was surprised when the ArcGRID support was dropped from Classic, again because it works in GUI. While the above are inconveniences, accessing Landsat 8 OLI data is extremely important. I absolutely agree with Mike, we need L8 support in Classic. Many of us are not working with the GUI and most of my users have no immediate plans to learn this new interface. We all agree on the need to use the new Landsat OLI data.

I think the issue for me isn't too much about learning the new interface. It's simply some of the things aren't yet working in ENVI 5 while they do in Classic. Flipping back and forth between the 2 interfaces isn't all that efficient. Besides, I can't imagine that implementing the Landsat 8 Reader in Classic would be that much work. I think it's understandable Exelis is 'phasing out' the Classic version, but it'd be nice if first ALL the functionality from Classic is transferred over first. I do think the new ENVI 5 interface can be great eventually. But when I can't even get the crosshairs in all of the open views, which I hoped to see with one of the SP's released and asked for already when ENVI 5 came out, I just go back to the Classic version where I have that option. Until all those little things (and bigger ones) are implemented in the new interface, I'm glad at least that I'm not the only one who likes to see the Classic version be around a bit longer - with hopefully updated features. :)

I see it's been a while, but have you found a solution yet?

With the release of ENVI 5.2, a new ENVI task was introduced that can be used with the new API to calibration Landsat 8 data. The task is ENVIRadiometricCalibrationTask. Documentation can be found in the ENVI 5.2 docs under is Programming > Routines > Data Processing > ENVIRadiometricCalibrationTask. I am afraid that TMCAL_DOIT is not updated for Landsat 8 data, and I don't see any plans to change TMCAL_DOIT to add support for Landsat 8. Regards, Peg Exelis VIS
