Charles Toth 2016

PRESIDENT: Charles K. Toth is a Research Professor in the Department of Civil, Environmental and Geodetic Engineering at OSU. He received his MSc in Electrical Engineering and a PhD in Electrical Engineering and Geo-Information Sciences from the Technical University of Budapest, Hungary. He has published over 300 peer-reviewed journal and proceedings papers, and he is the co-editor of the widely popular book LiDAR: Topographic Ranging and Scanning Principles and Processing. Toth joined ASPRS in 1988. From 2004-2008 he served as Assistant Director, then Director of the Photogrammetric Applications Division (PAD). Since 2008 he has served as the ASPRS Eastern Great Lakes Region National Director. He is also President for the 2012-2016 Congress Period of Technical Commission I for the International Society for Photogrammetry and Remote Sensing (ISPRS).

Toth said, “ASPRS is the premier society for geospatial information science and engineering professionals, uniquely blending government, the private sector, and academia. It is absolutely essential for the entire society to maintain its position of leadership as the broad use and application of remote sensing and geospatial data reaches many users who are not traditional members of ASPRS.” Toth continued, “we must be more proactive, demonstrating our knowledge and competence to solve problems for humankind, including disaster response, environment, climate change, peacekeeping, and food supply… I look forward to serving as an officer of ASPRS with honor and responsibility.”

mortonPRESIDENT-ELECT: Rebecca (Becky) Morton, CP, CMS

Becky Morton is President and CEO of GeoWing Mapping, Inc. (GeoWing), based in San Francisco, California. She founded the company in January of 2015 with the goal of offering both traditional photogrammetric mapping services as well as services related to unmanned aircraft systems (UAS). Her fascination with UAS photogrammetry began several years before she started her company. She was impressed by the accessibility of the new technology. For the first time, she could consider integrating and flying her own mapping cameras!

Ms. Morton is certified by ASPRS as a Mapping Scientist GIS/LIS and as a Photogrammetrist. She holds a bachelor’s degree in psychology and has taken post-graduate studies in computer science. Prior to the start of GeoWing, Becky practiced photogrammetry with Horizons, Inc., Fugro EarthData, Inc., and Towill, Inc. Over these years she has served in a variety of positions beginning in the role of Programmer/Analyst responsible for systems integration and the translation of mapping data, followed by positions as Orthophoto Systems Manager, Director of Business Development, Regional Manager, and Senior Program Director. In addition, Becky established and ran a small GIS company, RAMCad, for 8+ years to provide historical georeferenced imagery to the US Army Corps of Engineers and GIS application development services for numerous clients.

Becky Morton has been an active member of ASPRS since 1995, providing service to the Society at the Regional and National levels. She served as a regional officer from 2006-2013. She began her national leadership by serving first as Assistant Director and then Director of the Photogrammetric Applications Division from 2006-2010, where she worked with others in the development of standards and guidelines for lidar data and mapping accuracy. From 2010-2014 she served as Assistant Director and then Director of the Professional Practice Division where she worked with others on the writing and adoption of the ASPRS Guidelines for Procurement of Geospatial Mapping Products and Services. From 2012-2014 she served as Chair of the Division Directors Committee. In 2012, she served as Chair of the Corporate Sponsors Committee for the 2012 Annual Conference in Sacramento. In 2012-2013, she served on the ASPRS Restructuring Task Force. In 2013, she served on the Selection Committee for the ASPRS Executive Director. In 2014, she served as the Conference Chair for the UAS MAPPING 2014 RENO symposium and technical demonstration. Also in 2014, she was appointed by the ASPRS Board of Directors to head a UAS Task Force whose work resulted in the formation of the UAS Division. She is active on several ASPRS committees such as the Licensure Exam Writing Committee, Evaluation for Certification Committee, the Kenneth J. Osborn Memorial Scholarship Committee, and the planning committee for the UAS MAPPING 2015 RENO symposium. She has received two ASPRS Presidential Citations (2009 and 2011) and one ASPRS Outstanding Service Award (2013). Ms. Morton is active in other geospatial organizations and served from 2008-2011 on the Board of Directors for a regional URISA chapter.
