Workshops held on Sunday, March 23rd:

WS 1 - From Lidar Point Clouds to Forest Biophysical Parameters:  Theoretical Concepts and Hands-On Processing

 

Date: Sunday, March 23, 2014
Time: Full Day – 7:45 am – 5:15 pm
CEUs: 0.8

Instructor(s): Sorin Popescu and Ryan Sheridan, Texas A&M University

Level & Description: INTERMEDIATE WORKSHOP

This workshop is intended for participants who are looking to expand their basic knowledge of lidar remote sensing. Participants are expected to have a basic understanding of lidar, remote sensing techniques, and image processing. The overall goal of this workshop is to introduce participants to advanced theoretical lidar concepts and employ open source software packages (such as FUSION*, LASTools**) to provide hands-on experience utilizing lidar data for forest vegetation assessment. Participants are requested to bring their own laptops with prior installation of the open-source software. Lidar data will be provided by workshop instructors.

Theoretical concepts covered during this workshop include:
1. Review basic laser ranging concepts, lidar data structure, and the LAS data format
2. Introduce types of lidar sensors for forest vegetation assessment, including discrete-return, waveform encoding, and photon counting systems, on terrestrial, airborne, and satellite platforms
3. From point clouds to interpolated surfaces: review of basic algorithms for deriving information on terrain elevation and canopy height models
4. 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
5. Discuss examples of various lidar remote sensing applications for characterizing vegetation parameters, including biomass assessment in various ecosystems, such as forests, brush, and marshes, leaf area index, canopy cover, and mapping of surface and canopy forest fuels.

Hands-on processing topics include:
1. Preprocessing lidar data (e.g. tiling flight lines, merging tiles, subsetting)
2. Classification of lidar point clouds to identify vegetation, ground, and other point classes.
3. Derivation of lidar point cloud metrics commonly utilized for vegetation analyses.
4. Application of linear regression with lidar metrics to estimate forest biophysical parameters.
5. Utilization of point clouds for surface creation (digital elevation models, digital surface models, and canopy height models).
6. Overview of a method of deriving individual tree measurements from canopy height models.

WS 4 - Introduction to Unmanned Aerial System (UAS) Operations

Date: Monday, March 24, 2014
Time: All Day; 7:45 am - 5:15 pm
CEUs:0.8

Instructor(s): Kevin Gambold and Ed Freeborn, Unmanned Experts LLC

Level & Description: INTERMEDIATE

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 discussion 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; Communications

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 advanced understanding of airborne operations, and a basic understanding of photogrammetric and remote sensing principles or their equivalents in military intelligence, surveillance, and reconnaissance (ISR) fundamentals.

 

WS 5 - Object-Based Image Analysis

 

Date: Monday, March 24, 2014
Time: Full Day – 7:45 am – 5:15 pm
CEUs: 0.8

Instructor(s): Jarlath O'Neil-Dunne, University of Vermont

Level & Description: ADVANCED WORKSHOP
This full-day, advanced workshop is designed to help participants harness the true power of object-based image analysis (OBIA). It is recommended that participants have a strong foundation in remote sensing and GIS, and at least some exposure to OBIA. This workshop is particularly well suited to individuals who are finding it difficult to extract information from the latest generation of high-resolution imaging and LiDAR sensors using OBIA techniques. Specific emphasis in this workshop will be paid to moving beyond the standard “segment and classify” approach that is typically employed in most OBIA projects, to an iterative workflow that better mimics the type of mapping carried out by human analysts by fully incorporating the spectral, geometric, and contextual information present in an image. Through a series of lectures, demonstrations, and hands-on exercises, participants will be exposed to the methods that will enable them to build effective and efficient OBIA routines.

The workshop will be divided into four parts. In the first part, the theoretical foundation for the effective application of OBIA technology will be laid out by drawing from the remote sensing, neurobiology, and cognitive sciences literature. This will be followed by a review of the current approaches to OBIA, with particular attention to some of the pitfalls that often prevent OBIA technology from being applied to its full potential. The second part will focus on effective approaches to and best practices for object-based feature extraction, including a thorough review of segmentation algorithms. The third part will cover more advanced topics, including: 1) image object fusion, 2) pattern recognition, 3) morphological routines, and 4) context-based classification. The workshop will conclude with recommendations on how to design and deploy enterprise OBIA systems capable of processing of datasets containing billions of pixels.

Demonstrations and exercises will make use of a broad range of remotely sensed (e.g. imagery and LiDAR) datasets and a particular focus in the exercises will be integrating remotely sensed and thematic datasets in an OBIA context. Participants will receive a workshop manual, sample OBIA projects that include data and algorithms, and a series of video tutorials. Participants are encouraged to bring their own computers to use during the hands-on exercises. OBIA software will be provided (requires Windows XP, Vista, or 7).

CEUs: 0.4

Instructor(s): Lewis Graham, CTO of GeoCue Corporation and Division Director of the ASPRS LIDAR Division

Level & Description: INTRODUCTORY WORKSHOP

Mobile Laser Scanning (MLS) is becoming more and more prevalent as a technique for moving road and rail survey from the field to the office. MLS exploitation tools allow users to visualize road/rail ways and extraction information from the safety and convenience of office environments. Initially the domain of data collection companies, new desktop tools are enabling end users of MLS data to perform meaningful data exploitation.
In this workshop, we will cover some of the basic principles of MLS data exploitation using a hands-on approach.

Topics include:
• What is a Mobile Laser Scanning System?
• The importance of laser/digital image fusion in an MLS system
• Considerations of accuracy
• Data Management
• Visualization
• Simple measurements
• Attribute collection
• Limitations of MLS

This will be a hands-on workshop with software and sample data provided to the students. Each student will be expected to bring a laptop computer with the following minimum specifications:
• Windows 7 or Windows 8, 64 bit
• 4 GB minimum RAM
• 20 GB of available disk space
• Available USB port for data loading (USB 3.0 preferred, USB 2.0 acceptable)
