Dr. Riadh Munjy
Dr. Riadh Munjy got his MSCE in civil Engineering in 1978, MS in Applied Mathematics in 1981, and Ph.D. in Civil Engineering in 1982 from the University of Washington. He has been a faculty member and an active researcher at California State University, Fresno since 1982 and has been a Professor of Civil and Geomatics Engineering since 1988. He has over thirty years of experience in teaching courses in photogrammetry, digital mapping, GIS and least squares adjustment.  From 1992 till 2003, he participated with JPL to develop an Interferometric Dual Band Radar Mapping System (GeoSAR). He has been a consultant in digital mapping for many agencies and firms around the world and worked as an expert witness in a number of cases.
A member of ASPRS since 1978, Munjy has been a regular participant in ASPRS annual and fall conventions. He served as the Chairman of the Close Range Photogrammetry from 1986 through 1988 and was associate editor for theoretical and applied photogrammetry for Photogrammetric Engineering and Remote Sensing journal from 1991 till 1996. In 1997 he was awarded the Meritorious Service Award by ASPRS. 
He is a registered Civil Engineer in the State of California and ASPRS Certified Photogrammetrist.

Abstract: The goal of instructing Geomatics Engineering students in the rapidly evolving 3D imagery field was the driving force in transforming the traditional photogrammetric stereoplotter room into a new state-of-the-art facility and capability.  The development and implementation of Fresno State’s new 3D Photogrammetry Lab will be discussed.

Dr. Anne Lilje
Dr. Anne Lilje joined Esri in 2009 and holds the title of Product Engineer. She is currently the Lead of Esri’s Professional Services 3D and Imagery Team. One of this team’s main goals is to push the boundaries of 3D and Imagery GIS technologies with a focus on the importance of imagery in the creation of 3D content. 
Prior to coming to Esri, Dr. Lilje worked at The Aerospace Corporation in El Segundo, California where her focus involved the development of geospatially enabled multi-sensor systems for the Intelligence and Defense Communities. She was also part of an Aerospace/JPL team that created a new high-resolution SAR capability for the Goldstone Solar System Radar Array. This array was used to create the first high resolution maps of the lunar South Pole. Prior to Aerospace she worked at the California Institute of Technology in Pasadena, California building and managing their first GIS Laboratory.
Dr. Lilje received her Ph.D. in Geological Sciences at the University of California Riverside, where she studied a wide array of topics including the physics and chemistry of deep sea sediment compaction, the probabilistic and statistical analysis of taxon range zones and the sedimentology of the Salton Sea Geothermal Area.

Abstract: Current and historic methods used to create 3D Point clouds from imagery and extract geometries from these point clouds typically involve recreating scene geometries using the spatial and/or spectral characteristics associated with each point. The concept of scene ambiguity that is inherent in scene reconstruction, however, is not well addressed. By applying a probabilistic point cloud model developed at Brown University in conjunction with a novel segmentation technique that is spatially, spectrally and scale sensitive the ambiguity factor can be quantified and minimized. In this discussion we will explore the use of these techniques and how they can further the science and art of extracting geometries from image derived point clouds.

Bob Vasquez, PLS
Mr. Vasquez is an associate and the California Survey Manager for David Evans and Associates, Inc. (DEA) with over 25 years of experience in surveying and mapping. He started his career at the Orange County Surveyors office and then moved to a much bigger county working for the San Bernardino County Surveyors office. After 20 years of public service, Mr. Vasquez joined DEA as a survey project manager for various projects including boundary surveys, design and construction surveys, land development surveys, airport surveys, heavy and transit rail surveys, 3D laser scanning, right of way engineering and mapping to name a few.  He is currently the California Survey Manager.

Abstract: Imagine a surveying vehicle equipped to capture 3D measurements and data in a single crossing of your project site. Through GeoAutomation® technology, mobile mapping solutions are cost effective, schedule-friendly, and more accurate than ever before. GeoAutomation® is an advanced photographic imaging and data reduction system that can be used for asset management, GIS data collection, pavement assessment, virtual facility management, inventory, engineering surveys, risk management, 3D modeling, and conventional surveying and mapping.  Cities, counties, state agencies, DOTs, utility districts and emergency services can all benefit from a data set that provides attribute information as well as multiple color views of a feature in its surroundings.
