LiDAR Special Interest Group, part 1
USGS 3DEP Lidar Data in OpenTopography
Presenter: Christopher Crosby
The USGS 3D Elevation Program (3DEP) is an ambitious effort "to complete acquisition of nationwide lidar (IfSAR in AK) by 2023 to provide the first-ever national baseline of consistent high-resolution elevation data." Since 2015, USGS and federal, state, local, and non-government partners have collected over 2 million square miles of high resolution topography data, covering nearly 67% of the United States. These data are now available via OpenTopography, making it possible to seamlessly download, process, and visualize approximately 15 trillion lidar points. This effort leverages recent USGS efforts to make 3DEP data available in the cloud, and allows us to integrate into OpenTopography's existing on-demand discovery and processing workflow. OpenTopography is a National Science Foundation funded project dedicated to making high resolution topographic data easier to discover, access, and use for research, education, and other uses.
Takeaway: Availability of a new way to access USGS 3DEP Lidar data. Approaches to leveraging cloud-based data resources to improve data access. Lessons learned and metrics from ~8 months of 3DEP data utilization via OpenTopography.
Who should attend: Lidar/high resolution topographic data users. People involved in submitting 3DEP BAA proposals and/or those responsible for dissemination of USGS 3DEP Lidar data.
Remote Sensing Landscape Survey - City of Phoenix
Presenter: Darin Lisonbee
The City of Phoenix Water Services Department is conducting a Remote Sensing Landscape Survey using NAIP and LiDAR data to better understand changes in landscapes over time, focusing on how this corresponds to current and future outdoor water demand. This presentation will show tools, methodologies and data produced using remote sensing and GIS software at the City's disposal.
Takeaway: The audience can walk away with a basic knowledge of a structure and plan to produce their own landscape classifications for their organizations at a fairly high level of detail.
Who should attend: Planners, data analysts, policy makers, those interested in how to use LiDAR to their advantage, urban foresters.
Status of the 3D Elevation Program and 3D Nation Study
Presenter: Drew Decker
The National Map elevation data theme is supported by the 3D Elevation Program (3DEP). 3DEP's goal is to systematically collect enhanced elevation data for the nation over a multi-year period. A new round of 3DEP funds is expected to be made available later in 2020. The 3DEP Broad Agency Announcement will allow local, state, Tribal, educational, and other organizations to partner with USGS and other federal agencies to acquire new Lidar data. 3D Nation is a major new study in conjunction with 3DEP as the program progresses toward national elevation coverage. The study will document and refine the requirement and benefits of mission critical needs that use topographic data. 3D Nation expands to seek input on inland, nearshore, and offshore bathymetry needs and to help direct the program as initial coverage across the country is completed. This presentation will provide an update on 3DEP and 3D Nation for Arizona. It will include details on submitting proposals for funding.
Takeaway: Drew will provide the status of Lidar datasets in Arizona that are complete, in work, or planned. Provide an update on 3D Nation which has input from a number of participants from Arizona. He will also go over the steps in planning for a Lidar project including reviewing the Lidar inventory, collaboration, and the 3DEP BAA process for submitting proposals for funding.
Who should attend: GIS data users requiring access to or developing elevation data within Arizona. This includes users who may have applications dependent on elevation data, such as infrastructure, flood management, transportation, agriculture, and habitat management.
