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.

The Hawaiian Islands have one of the most diverse rainfall patterns on earth. Knowledge of these patterns is vitally important for a number of resource management issues, including the restoration and protection of native ecosystems, ground water and surface water development and protection, and planning for the effects of global warming. A new set of digital maps of mean monthly and annual rainfall from 1978-2007 for the major Hawaiian Islands has been developed. A monthly rainfall database was assembled with over 1,000 stations, using several gap-filling techniques to address missing values in the station records. "Virtual raingage" sites were estimated in remote areas based on patterns of natural vegetation. The final gridded maps were created using a Bayesian data fusion method that merged the station data with three predictor maps derived from Radar rainfall, MM5 model rainfall, and PRISM rainfall maps.

A new interactive website was created to make the rainfall maps, data, and related information easily accessible. Users can download map images, GIS and Google Earth layers, and station data or obtain information via an interactive map. To access the website, visit:

During summer 2010, Michigan State University partnered with the Hawai'i Fish Habitat Partnership (HFHP) and other organizations to complete a state-wide assessment characterizing Hawai'i stream condition. This assessment, conducted in support of the National Fish Habitat Action Plan, followed a landscape approach and used best available GIS data to characterize disturbances to stream habitat. We sought expert knowledge from local partners to select anthropogenic disturbance datasets, which were attributed to local and network stream catchments associated with individual reaches of the 1:24K National Hydrography Dataset. For each reach, disturbances at both scales were combined into a single cumulative score. Results of this work are being incorporated into the Atlas of Hawaiian Watersheds and are also being used by NOAA to assess effects of inland disturbances on priority coastal habitat. Despite its immediate utility, a refinement to the assessment is under way. Currently, we are developing a landscape-based classification of the ecological potential of Hawaii stream reaches. This classification will incorporate natural landscape variables that are unalterable by humans and climate variables known to be important in structuring physical and biological characteristics of streams. We will use a multi-step process to select influential variables and will rely on biological data to ensure ecological meaning of resulting groups. With streams classified into specific groups, we can characterize vulnerability to climate change on a reach by reach basis. Additionally, we can use the classification to refine the condition assessment, allowing managers to consider disturbance in the context of stream type.

An Overview of the National Hydrography Dataset

Malie Beach-Smith

National Data Sets
Tuesday March 6, 2012 - 3:15 to 4:30 pm

The National Hydrography Dataset (NHD) is a comprehensive set of digital spatial data that contains information about surface water features such as lakes, ponds, streams, rivers, canals, dams and gages. Its rich set of attributes is continually maintained through system-wide revisions, a stewardship program, and contributions from the user community.

The NHD was designed to be simple enough for anyone with basic GIS skills to use, yet robust enough to allow for powerful geospatial analysis. These analyses are possible because the NHD contains a flow network that allows for tracing water upstream or downstream. It also provides a framework for linking scientific information such as water discharge rates, water quality, and aquatic population. These qualities give the NHD unique analytical powers for a number of scientific applications in the study of hydrology, pollution control, resource management, and fisheries biology.

This presentation will provide an overview of the structure of the NHD and its framework for linking scientific data to the NHD drainage network. Find out why the current generation of scientists and cartographers are adopting the National Hydrography Dataset as the standard for hydrography data. Hear how local partnerships continue to evolve this dataset to meet the challenges facing the earth sciences for the remainder of the century and beyond.

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.

Bringing Internet Data Content into GIS Applications

Real-Time Data Acquisition
Tuesday March 6, 2012 - 3:15 to 4:30 pm

GIS applications, whether they are hosted on a desktop or an Internet server, can pull data content from the Internet using links, feeds and services. GeoRSS is a standard for feeds in which the URL points to an XML file with geospatial tags. For example, by reading a feed that contains point coordinates, a GIS application can track moving objects. Services come in many formats that can be "mashed-up" in GIS applications. Beyond map and image services, GIS applications can take advantage of services specifically designed to query features, locate addresses, create travel routes, run geospatial models (geoprocessing), and more. This presentation will draw examples from the City and County of Honolulu's HONUA system for emergency management which uses a combination of links, feeds and services to provide a common operating picture that updates in real-time.

Resource Mapping Hawaii, Keaau, HI

Imagery Updates
Wednesday March 7, 2012 - 10:45 am to noon

Resource Mapping Hawaii in conjunction with The Nature Conservancy and Icoras Inc. have developed a never before seen capacity to accurately produce ortho-photo imagery at scales as low as 1cm GSD. The products from this sensor package are highly flexible ranging both in scale of aerial imagery to sensor products such as classic natural color, near infra-red, and thermal imagery. The sensor package can be mounted on a suite of platforms including small or large fixed wing aircraft or helicopter, giving it wide range of applications and ease of tasking. The proprietary image processing capability produced by Icoras allows for very fast turnaround of ortho products making near real time disaster management a reality. This unique capability of resolving at 1cm GSD was produced specifically for mapping and monitoring individual plant species distributions and change over time. This same capacity could however be used for any number of applications as of yet unthought-of of due to its exceptional detail. The image format and scale also make it user friendly to even the most novice.
