quency. A brief introductory presentation will provide an over-
view of many of the Center’s products and services that utilize the
same spatial tools and technical methods. Questions and answers
to technical topics will be incorporated into the demos to provide
immediate feedback and discussion for participants.
Workshop #3
Introduction to Unmanned Aerial System
(UAS) Operations
Kevin Gambold,

Monday, October 28th, 7:45 am to 5:15 pm, CEU 0.8
INTERMEDIATE WORKSHOP
The airborne remote sensing, survey and mapping community
are showing increasing interest in Unmanned Aerial System
(UAS), and new adopters and technology for metric-quality data
production are being reported daily. As UAS become operational
the ‘How and Why’ of UAS operations need to be considered as
well as the ‘What.’ The “Introduction to UAS Operations” full-day
workshop is designed to address this need with practical discus-
sion and a focus on metric-quality UAS surveying and mapping.
The workshop is broken down into 4 sections:
Introduction to UAS Concepts
• Overview; UAS Terminology and Classification; UAS Roles
and Mission Sets
• Concept of Operations; Launch Recovery Systems; Commu-
nications
Case Studies
• Metric-quality Applications and Systems Survey
• Small UAS (SUAS) Photogrammetry, a Disruptive Technology
Business Model
• Business Plan
• Operational Model
• Other Considerations
Wrap-up
• Future Technology
• Art of the Possible
This course assumes that attendees have an intermediate to ad-
vanced understanding of airborne operations, and a basic under-
standing of photogrammetric and remote sensing principles or
their equivalents in military intelligence, surveillance, and recon-
naissance (ISR) fundamentals.
Workshop #4
Looking Above the Terrain: Lidar for
Vegetation Assessment
Sorin Popescu,
Texas A&M University
Monday, October 28th, 7:45 am to 12:15 pm, CEU 0.4
INTERMEDIATE WORKSHOP
The participants are expected to have a basic understanding of re-
mote sensing techniques and image processing. The overall goal
of this half-day workshop is to introduce participants to lidar con-
cepts, processing techniques, and applications for characterizing
forest vegetation three-dimensional structure and deriving forest
biophysical parameters.
More specific objectives are to: (1) review basic laser ranging
concepts and lidar data structure; (2) introduce types of lidar sen-
sors for forest vegetation assessment, including discrete-return,
waveform encoding, and photon counting systems, on terres-
trial, airborne, and satellite platforms; (3) describe the LAS lidar
data format; (4) introduce participants to software resources for
processing lidar data and characterizing vegetation structure;
(5) review algorithms for deriving information on terrain eleva-
tion and canopy height models; (6) present choices of lidar data
processing, such as point-cloud statistics, waveform processing,
and interpolated surface-based methods to derive information on
vegetation structure at various scales, from individual tree, plot,
footprint, and stand level to regional and global scales; and (7)
discuss examples of various lidar remote sensing applications for
characterizing vegetation parameters, including biomass assess-
ment in various ecosystems, such as forests, brush, and marches,
leaf area index, canopy cover, and forest fuels mapping.
