TWI Finish Line
Anonym
Hello
Everyone,
This is officially my last blog as an Army Training with
Industry (TWI) Student, although you will certainly hear from me again. Can you
believe a year has passed already? When I came on board at Harris Geospatial
last August the goal was to facilitate mutually improved understanding,
strengthen the partnership and better learn ENVI to ultimately enhance the US
Army’s combat effectiveness. With all that has been learned, shared and
documented in the last 12 months, I think we’ve accomplished what we set out to
do and more. I was made to feel as though I was a part of the Harris Geospatial
team. To reciprocate this hospitality, a few Army Challenge Coins have been
passed out this week. If you are a Soldier, then you know what that means.
Harris is a part of the team, so when you see a member at the upcoming ENVI
Analytics Symposium or any other conference or encounter, challenge them to
show you their coin or beverages are on them; just kidding about the beverages J.
With respect to the past twelve months, I’d say it has
been an absolute marathon of learning. When I first arrived, my experience with
ENVI was novice at best. I had successfully implemented solutions such as
anomaly detection and change detection during tours in Operation Iraqi Freedom
and Operation New Dawn. However, like many other Defense & Intelligence
users, I was still heavily reliant on other software suites to perform certain
workflows, such as mosaicking, orthorectification and producing specialized
Compressed Arc-Digitized Raster Graphics (CADRG). This wasn’t because ENVI
couldn’t accomplish these tasks, but rather because Soldiers like me just
didn’t know how to using ENVI.
I’m confident enough to now say that this
knowledge gap has been bridged for the D&I community with the help of the
ENVI Pocket Guides, VOLUME 1 | BASICS and the recently finished VOLUME 2 |
INTERMEDIATE.

Volume 1 provides succinct instructions on how to perform
the following tasks using ENVI:
1. Understand
the Interface
2. Mosaic
data
3. Subset
data
4. Orthorectify
data
5. Pan
Sharpen data
6. Perform
change detection
7. Perform
anomaly detection
8. Produce
a terrain categorization (TERCAT)
9. Export
data to CADRG
Volume 2 builds on the basics by providing succinct steps on
how to perform the following tasks using ENVI and IDL:
1. Add
Grid reference & count features
2. Perform
Band Math
3. Layer
Stack images
4. Exploit
Shortwave Infrared (SWIR) bands
5. Perform
Spectral Analysis in general
6. Perform
Image Calibration/ Atmospheric Correction
7. Extract
features from LiDAR
8. Batch Processing using IDL
Keep an eye on this blog for a hyperlink to VOLUME 2 of the
Pocket Guide. It’s currently being formatted and printed.
TWI has been an honor and a privilege. I strongly recommend
continuation of this program by both Harris Geospatial and the Army. I can
certainly say that Army Technicians’ and Noncommissioned Officers’ development
yearns for such opportunities. There is absolutely no way I could have learned
enough to compile the Pocket Guides in any other setting. Again, it has been a
marathon, but I’d do it again in a heartbeat. Thanks for the hospitality and
opportunity from the bottom of my heart to the good folks at ENVI.
