WS #4 - Looking Above the Terrain: Lidar for Vegetation Assessment....TIME & DATE CHANGE

Workshop #4 - Looking Above the Terrain: Lidar for Vegetation Assessment 

The participants are expected to have a basic understanding of remote sensing techniques and image processing. The overall goal of this half-day workshop is to introduce participants to lidar concepts, 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 sensors for forest vegetation assessment, including discrete-return, waveform encoding, and photon counting systems, on terrestrial, 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 elevation 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 assessment in various ecosystems, such as forests, brush, and marches, leaf area index, canopy cover, and forest fuels mapping.

WS #5 - QA/QC Processes and Concepts

Workshop #5 - QA/QC Processes and Concepts

The workshop is intended for individuals who are involved in any aspect of production process control and management including geometric and radiometric quality and accuracy assessment. Users who receive products from data providers may also benefit from the workshop as it helps them understand the process of product evaluation and acceptance criteria. The workshop introduces the topics of quality control and quality assurance and how do they apply to day-to-day activities in improving products quality through the improvement in the process control.  In addition, the workshop will introduce practical and simplified approach for the statistical terms and concepts used in evaluating final products with real examples from lidar and ortho projects life cycles.
