A Legal Framework for UAVs: How We Get From Here to There?, May 29, 2015
To register, click here.
Abstract: UAVs offer tremendous potential to collect geospatial information in ways that will both replace and supplement existing collection capabilities. Unfortunately, trying to integrate broad commercial use of UAVs into the existing legal and policy framework is proving very challenging. This webinar will identify the major legal and policy issues that must be addressed and discuss what such a framework might look like in the future to accommodate commercial use of UAVs.
Bio: Mr. Pomfret is the founder and Executive Director of the Centre for Spatial Law and Policy and the Principal in GeoLaw, P.C, where he advises business and governments on the legal issues associated with the collection, use, storage and distribution of location and other forms of geospatial information. Mr Pomfret has given talks around the world on matters of spatial law and policy and writes regularly on issues of privacy, licensing, national security and liability issues and the use of geospatial technology in the courtroom and is the principal author of chapter on location privacy in the United States in Geographic Data and the Law: Defining New Challenges. Mr. Pomfret has been involved in geospatial technology for over 25 years, beginning his career as a satellite imagery analyst where he helped to develop imagery collection strategies to monitor arms control treaties and identify requirements for future collection systems. He is a member of the Board of Directors of the OpenGeospatial Consortium and was appointed to the National Geospatial Advisory Committee.
A Discussion of the USGS Base Lidar Specification, v. 2.0, June 19, 2015
To register, click here.
Abstract: The U.S. Geological Survey (USGS) National Geospatial Program (NGP) Lidar Base Specification Version 1.0 was published in early 2012, and revised as Version 1.1 in 2014. The notable revisions in version 1.1 were definitions for 3D Elevation Program (3DEP) Quality Levels, alignment with the American Society for Photogrammetry and Remote Sensing Positional Accuracy Standards for Digital Geospatial Data, updating the delivery format to LAS version 1.4, and clarification of several requirements. The version 2.0 update will further align with new industry standards and best practices, define requirements for additional 3DEP products and services, and address new lidar technologies.
As a cooperative effort of the 3DEP and the National Hydrography Dataset (NHD) program, the NGP is developing a common data dictionary for both topographic and hydrologic breaklines. The goal is to enhance the integration of the NHD and 3DEP elevation products by enabling the use of common linework to the highest degree possible. This data dictionary is the most exciting update to the specification. Although 3DEP lidar projects require only minimal hydrographic breaklines to be collected for hydro-flattening, those features will be consistently formatted and immediately usable by the NHD as well.
This presentation will preview the changes from version 1.1 to version 2.0 and provide an opportunity for attendees to have questions about the specification answered.
Bio: Karl Heidemann has worked in the lidar industry for over 15 years as a user, data provider, and software architect. He currently is a member of the Topographic Sciences Team at the USGS EROS Data Center. Mr. Heidemann currently chairs the ASPRS Airborne Lidar Committee, is the author of the USGS-NGP Lidar Base Specification, and is a contributing author to the ASPRS Manual of Airborne Topographic Lidar, the ASPRS Positional Accuracy Standards for Digital Geospatial Data, the ASPRS Airborne Topographic Lidar Manual, and the forthcoming 3rd Edition of The DEM User's Manual.
USGS Science Data Catalog – Data Visualization, Discovery and Use, August 28, 2015
To register, click here.
Abstract: The Office of Science and Technology Policy (OSTP) White House Open Data Policies (2013) have required Federal agencies to establish formal catalogues of their science data holdings and make these data easily available on Web sites, portals, and applications. As an organization, the USGS has historically excelled at making its data holdings freely available on its various Web sites (i.e., National, Scientific Programs, or local Science Center). In response to these requirements, the USGS Core Science Analytics, Synthesis, and Libraries program, in collaboration with DOE’s Oak Ridge National Laboratory (ORNL) Mercury Consortium (funded by NASA, USGS, and DOE), and a number of other USGS organizations, established the Science Data Catalog (http://data.usgs.gov) cyberinfrastructure, content management processes/tools, and supporting policies. The USGS Science Data Catalog led the charge at USGS to improve the robustness of existing/future metadata collections; develop mechanisms to perform automatic data visualization using services; streamline and develop sustainable publishing to external aggregators (i.e., data.gov); and provide leadership to the U.S. Department of Interior in emerging Open Data policies, techniques, and systems.
The session will focus on the USGS SDC current approaches to data visualization, discovery of USGS data resources, and aiding in the use of USGS data services by multiple stakeholder organizations.
Bio: Mike Frame is Chief of Computational Science, U.S. Geological Survey (USGS). He is responsible for enabling better use and application of scientific data through developing data access/interoperability strategies and the implementation of technologies such as: knowledge portals, data integration tools, analysis/visualization technologies, geospatial applications, standards, and indexing/discovery methods. He has served as Principle Investigator on several US National Science Foundation projects, international councils, and initiatives.
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.
