LiDAR Data Management and Exploitation
Joe Bob Penor
Intergraph, Reston, VA
LiDAR for Infrastructure and Terrain Mapping
Monday March 5, 2012 - 3:15 to 4:30 pm
Is your agency utilizing or considering using LiDAR data? If so, you know that LiDAR technology has become a valuable tool in a variety of applications where an accurate surface model is required. The availability of LiDAR data has proliferated both here in Hawaii and elsewhere. The availability of LiDAR data is resulting in a profusion of very large datasets requiring solutions for management and exploitation. During this session, we will highlight the benefits of LiDAR data, and explore local, state, federal and DOT workflows using LiDAR data (and other data types) in response to a natural disaster. We will demonstrate the managing, exploitation and dissemination of LiDAR in emergency planning, recovery and rebuilding. In addition, we will also showcase how LiDAR data analysis can be performed in GIS, remote sensing and photogrammetry applications.

Maximizing the Benefits of LiDAR Data in GIS
Steve Snow
Esri, Redlands, CA
LiDAR for Infrastructure and Terrain Mapping
Monday March 5, 2012 - 3:15 to 4:30 pm
This presentation introduces GIS professionals to the many uses of airborne LiDAR and how to utilize GIS software to extract valuable information from the data as well as combine it with existing geospatial information. Application examples for energy, natural resources, and critical infrastructure mapping will be reviewed to highlight the possibilities and challenges of working with this new & exciting source of highly accurate 3D information.

Results of the National Enhanced Elevation Assessment
Kirk Waters

Gregory Snyder

LiDAR for Infrastructure and Terrain Mapping
Monday March 5, 2012 - 3:15 to 4:30 pm
The National Enhanced Elevation Assessment was completed in December of 2011. The effort was led by USGS and funded by multiple agencies. Eight scenarios for a national enhanced elevation data program were evaluated. All scenarios considered the tradeoffs between benefits and costs for varied elevation data quality and replacement cycles. While every scenario resulted in a positive benefit cost ratio, the range of needs met varied from 13 to 66 percent of the requirements identified in the study. Additional scenarios are being examined for meeting a greater percentage of needs, particularly for uses that require very high levels of data quality. Using conservative numbers, the scenarios produced maximum expected benefits of over $1B annually. The assessment also concluded that the current cooperative program was efficient and resulted in relatively little duplication. The level of current investments nationally, however, was not sufficient to meet more than about 10 percent of the identified requirements. As part of the project, a detailed inventory of existing elevation data, including the Pacific Islands, was developed as a planning baseline.

KEYNOTE: Positioning the Pacific
Juliana Blackwell
Director, NOAA National Geodetic Survey
Tuesday March 6, 2012 - 8:45 to 10:15 am
This presentation will highlight NOAA's National Geodetic Survey and other NOAA geospatial activities in the Pacific Region. Topics to be covered include an overview of selected NOAA geospatial data and services supporting mapping and charting, comprehensive ocean and coastal planning, new approaches for visualizing and using NOAA data, including the latest mobile applications, and the development of a new NOAA Geospatial Platform for access to the breadth of NOAA's geospatial data, services, and applications.

New US Topos for Hawaii and More: A USGS National Geospatial Program Update

National Data Sets
Tuesday March 6, 2012 - 3:15 to 4:30 pm
This presentation will provide an update on several mapping efforts by the USGS. The first is the new National Map viewer which is an improved viewing platform, base map data, and an integrated data download service. The second effort is the new US Topo map scheduled to be published in Hawaii in 2012. US Topo is the next generation of digital topographic maps from the U.S. Geological Survey. Arranged in the traditional 7.5-minute quadrangle format, digital US Topo maps are designed to look and feel like the traditional paper topographic maps for which the USGS is so well known. At the same time, US Topo maps provide modern technical advantages that support wider and faster public distribution and enable basic, on-screen geographic analysis for all users. The historic topographic quadrangle scanning efforts will also be discussed which is an integral part of the US Topo publication process.

Hawaii Datum Transformations
This a new document that lists the best choices for datum transformations commonly needed in Hawaii by ArcGIS users. Includes Old Hawaiian Datum, NAD83(86), NAD83 HARN AND WGS84.
A word of caution - when someone says they are using NAD83, be sure to clarify which NAD83. The original NAD83 used in Hawaii is NAD83(86). The current NAD83 used in Hawaii is NAD83 HARN. The current NAD83 is also called NAD83 PACP00 (those are two zeroes on the end, say "pack-pee-zero-zero" not "pack-pooh").
