New Positional Accuracy Standards for Digital Geospatial Data, September 25, 2015

To register, click here

Abstract: The new ASPRS accuracy standards fill a critical need for map users and map makers alike. For centuries, map scale and contour interval have been used as an indication of map accuracy. Users want to know how accurately they can measure different things on a map, and map makers want to know how accurate maps need to be in order to satisfy user requirements. Those contracting for new maps depend on some form of map accuracy standard to evaluate the tradeoff between the accuracy required vs. how much time and expense are justified in achieving it, and then to describe the accuracy of the result in a uniform way that is reliable, defensible, and repeatable.

The new ASPRS standards address recent innovations in digital imaging and non-imaging sensors, airborne GPS, inertial measurement units (IMU) and aerial triangulation (AT) technologies. Unlike prior standards, the new standards are independent of scale and contour interval, they address higher levels of accuracies achievable by the latest technologies (e.g. unmanned aerial systems and lidar mobile mapping systems), and they provide enough flexibility to be applicable to future technologies as they are developed. Finally, the new standards provide cross references to older standards, as well as detailed guidance for a wide range of potential applications.

Bios

Dr. David F. Maune is the Senior Remote Sensing Project Manager at Dewberry Consultants LLC, headquartered in Fairfax, VA, where he manages Dewberry's Geospatial Products and Services Contract with the U.S. Geological Survey (USGS), including the ongoing statewide IFSAR mapping of Alaska, and similar geospatial contracts with NOAA's Office for Coastal Management (OCM), NOAA's National Geodetic Survey (NGS), and the Department of Homeland Security (DHS). He is the editor and principal author of the 1st and 2nd editions of Digital Elevation Model Technologies and Applications: The DEM Users Manual, published by the American Society for Photogrammetry and Remote Sensing (ASPRS). He is an ASPRS Fellow, a charter member of the National Geospatial Advisory Committee (NGAC), and a member of NOAA's Hydrographic Services Review Panel (HSRP). He is the author of NOAA's National Height Modernization Study – Report to Congress which justified the need for NGS' Height Modernization Program; and he is the author of the National Enhanced Elevation Assessment (NEEA) which provided the blueprint for USGS' 3D Elevation Program (3DEP). For the U.S. Army Corps of Engineers, he is the editor and principal author of USACE EM 1110-1-1000, Photogrammetric and Lidar Mapping. He is a co-author of the new ASPRS Positional Accuracy Standards for Digital Geospatial Data.

His current responsibilities include designing and managing strategic programs to develop and implement new remote sensing technologies focused on meeting the evolving needs of geospatial users. Currently, Dr. Abdullah is a lead research scientist and a member of Woolpert Labs team. His latest accomplishments include the calibration and processing of data from the single photon counting LiDAR and leading Woolpert research activities in the field of Unmanned Aerial System (UAS), its sensor calibration, and its workflow development. Dr. Abdullah publishes a monthly column "Mapping Matters", in the ASPRS journal PE&RS and he is the recipient of the 2010 prestigious Photogrammetric Fairchild award of the ASPRS and he serves as an adjunct professor at the University of Maryland, Baltimore County and at Penn State teaching graduate courses on UAS, Photogrammetry and Remote Sensing.

GNSS Derived Heights, November 20, 2015

To register, click here

Abstract: Geospatial practitioners have several methods to produce precise and accurate horizontal data from Global Navigation Satellite Systems (GNSS). However, the vertical data produced are typically 1.5 to 2.5 times less precise and require more attention to produce survey grade results. When our new national vertical (geopotential) datum is rolled out around 2022, the primary access to the datum “truth” will be by remote means to the national CORS network, as opposed to using NAVD 88 marks in the ground published in the NGS integrated database. Many users will also access the new datum from other active stations aligned to the National Spatial Reference System (NSRS) - especially real time networks. This lunchtime talk will take a brief look at the static and near real time methods that may enable us to obtain survey grade orthometric heights from GNSS, both now and into the near future.

Bio: William Henning, Prof.LS., is a Registered Professional Land Surveyor with over 46 years of active experience in all phases of the land surveying profession. He has been actively involved with education/outreach to the geospatial community for 20 years, presenting over 130 talks and workshops on surveying and GNSS technology. Mr. Henning has authored articles for professional journals and trade magazines on GNSS positioning as well as authoring an extensive guideline document on single base real-time GNSS positioning and spearheading a real-time network guideline document, while working at NOAA’s National Geodetic Survey (NGS). He has trained various federal and local personnel in using GNSS equipment and correct positioning techniques. He has been the project lead for new height modernization geodetic networks in county-wide projects in the U.S., where he planned, helped construct, processed, adjusted and managed new geodetic control systems using NGS guidelines. He has over 20 years experience working with various GNSS manufacturers’ real- time positioning systems. Mr. Henning is Past President of the American Association for Geodetic Surveying (AAGS) and is an ACSM/AAGS Fellow. He has been presented with the NOAA Administrator’s Award for outstanding accomplishment in producing real time GNSS guidelines. He is currently retired from the NGS, where as a Geodesist he helped develop guidelines and support methodology for real time GNSS positioning with state, national and international organizations. He is currently working in private industry as the Geospatial Manager for George William Stephens, Jr. & Associates, Inc. and as a faculty member for Geo-Learn, Inc., where he is recording instructional videos for the use of surveyors, engineers and other geospatial professionals. Mr. Henning was awarded the Maryland Society of Surveyors “Surveyor of the Year” for 2013-14.

Interchange of Provenance in GIS, October 23, 2015

Abstract: What will be the most significant development in GIS as an integrating technology over the next decade?   It may be argued that such a development will address the fractured nature of GIS-assisted problem solving across an increasingly broad array of timely domains (e.g., food and agricultural security, climate change, forest management, heritage preservation, urban and regional planning, etc.).  In the tradition that so many geospatial innovations are reported in journals, books, forums, etc. (and not easily transferable to software users), any single expert may only have limited practical access to the detailed GIS methodologies suitable to address a given problem statement.  In every GIS application, reliance is made upon the geoprocesses and workflows associated with geospatial artifacts produced.  What is still missing in GIS, and is related to intense emerging interest within computer systems and cyberinfrastructure, is a common framework for machine-queryable geospatial provenance (or lineage).  Remarkably, the need for such provenance was the rationale behind the first GIS patent in the U.S. more than two decades ago.  In a future GIS developmental cycle with cyber-enabled provenance exchange, GIS-assisted decision support and related geoprocessing and workflows will be far more open to scientific reproducibility, comparison, deduplication, trust, and innovation.  This presentation highlights the latest examples of provenance interchange in GIS and related cyberinfrastructure, and identifies top-down system framework, standards and specifications development, and usability challenges that are solvable within 5-10 years.

Bio: Jason A. Tullis is an Associate Professor in Geosciences and a member of the Center for Advanced Spatial Technologies (CAST) at University of Arkansas.  His research interests focus on remote sensing and GIS-assisted decision support in landscape health, geospatial provenance, and forest biophysical remote sensing.  He served as the Associate Editor of GIScience & Remote Sensing and is a contributor to Remote Sensing Handbook (CRC Press).  He is a technical advisor to EPA’s Climate Change Division and an active participant in the NASA SERVIR program.
