National and State Digital Elevation Program
Carol Ostergren, Geographer, USGS
Abstract: To more fully understand and better meet federal, state, local, and tribal needs, the National Digital Elevation Program is sponsoring a National Enhanced Elevation Requirements and Benefits
Assessment. The assessment will provide implementation options for optimizing the balance between cost and benefits in meeting priority national information needs. The assessment will also address these fundamental questions prior to detailed program planning:
- Is it more cost effective for the government to manage elevation activities within the context of a national program?
- Are there additional national or agency benefits derived from such a strategy?
- What does the optimized program look like?
The assessment is inclusive with respect to public and private input since no one sector can speak to all of the business requirements supported by elevation data. The assessment will help discover economies of scale, potential multiple data uses, and common business requirements that can be met through a more comprehensive national strategy for improving elevation data in the United States and its territories, including coastlines.
Bio: Carol Ostergren has worked for the US Geological survey for 27 years, and is looking forward to another 27. She started her career with USGS in Saudi Arabia doing field mapping and geologic map production on the Arabian Shield. She went to graduate school at Moss Landing Marine Lab, and then to full time work in the USGS Geologic Division. In 1995 she moved into mapping as program manager for the Digital Orthophoto Quadrangle program, and in 2000 moved to Sacramento to develop partnership opportunities for the states of CA and Hawaii. Carol is now working on partnership opportunities and framework data theme development for both CA and Nevada.
Using Remote Sensing & GIS for Energy & Minerals
Jim Ellis, Ph.D., Ellis GeoSpatial
DVC Remote Sensing/GIS Instructor
Abstract: Remote sensing & GIS are expanding and diverse tools for energy and mineral industries. Many satellites are orbiting the earth, collecting multiple images with different wavelengths. These “multispectral” satellites enable new maps to be derived for environmental and geological applications. Across shallow-water, modern carbonate environments, DEMs and landforms are derived from satellite imagery to better understand the geomorphometry of subsurface carbonate oil & gas reservoirs – and enable better models to be built. In Afghanistan, the DOD’s Task Force for Business & Stability Operations (TFBSO) is using remote sensing to detect and map mineral deposits. Images are processed with ENVI and ERDAS Imagine, integrated with ArcGIS, and interpreted by a senior geologist using GoogleEarth – all coordinated via web conferencing. Geospatial lessons learned on land are being applied to offshore, deepwater drill centers, pipelines, and floating hosts. Detailed equipment databases with x,y,z coordinates and extensive attributes are developed; integrated with bathymetric maps generated from side-scan sonar and seismic; shared with Virtual Remotely Operated Vehicle (VROV) simulation; and visualized in 2D and with video fly-throughs. Times are good for remote sensing & GIS in the energy & minerals sector.

Abstract: Elias Waggoner will present a basic description of LiDAR, including advantages and potential future uses. He will also discuss the ARRA Golden Gate LiDAR project including hyperspectral and aerial imagery and the value of collecting LiDAR, hyperspectral, and aerial image datasets concurrently. To close the presentation he will present some potential uses and projects for the dataset.
The DEVELOP National Student Internship Program at NASA Ames Research Center: Applications in Earth Science for Resource Management
Michelle Newcomer, Center Lead-Student Manger, NASA DEVELOP National Program
Additional Featured Student, NASA DEVELOP National Program
Abstract: Remote sensing technologies can provide useful tools for resource managers. The goal of the DEVELOP National Student Internship Program at NASA Ames Research Center is to incorporate NASA remote sensing technology into local, regional, state, and tribal agency decision making processes. Several projects completed by students working in this program have utilized cutting edge remote sensing technologies and image processing techniques for creating products useful to natural resource managers from the South Bay Salt Pond Restoration Project, the USGS Western Ecological Research Center, and the US Forest Service. Two of these projects are highlighted further in this presentation.
