NHD Applications Utilizing StreamStats -- February 28, 2014
The National Hydrography Dataset (NHD) serves as a framework for geospatial data representing the surface water of the United States. The features that make up the NHD have a basic set of attributes that describe these features and at the same time these features may have additional information linked to them describing other characteristics relating to hydrology, water quality, biology, regulations, and a host of other data. Is this linked information which contributes greatly to the power of the NHD to serve not just as spatial data, but also as an information system, and further as a base for analysis and knowledge.
This workshop introduces the NHD framework and how to use the HEM Tool to create events on the NHD. This can be performed on a case by case basis or by importing user databases. Attendees will also learn how to import these user-created events into StreamStats for analysis, including searches up and down the hydrography network, drainage area estimates, batch delineation of watersheds and more. New and improved tools will also demonstrate how to perform a variety of event searches on both the high resolution (1:24K) NHD data and the NHDPlus (medium resolution) data. The NHDPlus functionality will include linkages to a suite of EPA point-event datasets.
Presenter: Peter A Steeves
Pete Steeves has been a GIS Specialist for the USGS Massachusetts Water Science Center for 25 years. Massachusetts was the first State to set up a StreamStats web page back in the mid 90's, and Pete was instrumental in making this happen. After this local success, Pete was asked to help develop a National StreamStats site, and has been on the National StreamStats team ever since. More recently, the StreamStats site has expanded its tool base to utilize the navigation functionality of the NHD.
Modernization of the National Spatial Reference System -- March 14, 2014
During the next decade enhancements and additions to the network of Global Navigation Satellite Systems (GNSS) will significantly improve the use of space-based positioning systems for surveying, mapping, charting, navigation and numerous other applications. In order to meet the anticipated demands for an improved geospatial framework that these developments will require, the National Geodetic Survey (NGS) is implementing a plan for the modernization of the National Spatial Reference System (NSRS). Among the issues outlined in this plan is the adoption of an entirely new geodetic reference frame by 2022, with updated geometric (horizontal) and gravimetric (vertical) realizations that will replace the North American Datum of 1983 (NAD 83) and the North American Vertical Datum of 1988 (NAVD 88). This new framework will be designed to be virtually identical to and aligned with the International Terrestrial Reference Frame (ITRF), with orthometric heights based exclusively on gravity observations and a high accuracy geoid model. This presentation will highlight the rational for these changes; the various elements that currently define the NSRS.
Presenter: Dave Doyle
Dave Doyle joined the National Geodetic Survey in 1972, and held the position of chief geodetic surveyor upon his retirement in January, 2013. During his time at NGS his experiences included all phases of geodetic triangulation, astronomic positioning, leveling, GPS data collection, data analysis, datum transformations, network adjustments, and data publication. Mr. Doyle’s activities have included extensive efforts on the development and implementation of the North American Datum of 1983 and the North American Vertical Datum of 1988. He has also provided technical support to various countries for the modernization of national and regional geodetic reference systems in Caribbean and Central America, Africa, and the Pacific. Mr. Doyle is a Past President of the American Association for Geodetic Surveying, a Fellow member of the American Congress on Surveying and Mapping, a charter member of the Geographic and Land Information Society, and has served on the U.S. delegation to the International Federation of Surveyors.
Beyond Visualization: Enabling 3D Spatial Analysis of Vector Geometry -- April 11, 2014
In recent years, the geospatial community has embraced new technologies supporting 3D. However, most existing 3D GI systems are mainly used for visualization purposes such as models, fly through, simulations and animations. Systems that are capable of performing 3D spatial analysis on vector geometry provide only a narrow scope of functionality and don’t include many of the spatial analysis functions that are common in 2D, such as spatial relations operators, geometric set operators, buffers, and routing. 3D Topology can provide a framework for implementing the missing functionality. Topology fully defines all relationships and interactions between vector geometries that exist. LSI has implemented an ISO 19107 compliant 3D Topology plug-in for Oracle Spatial and a 3D Geometry Library plug-in for Oracle Spatial. These plug-ins allows users to perform analysis such as quality assurance of feature relationships, indoor/outdoor 3D routing and 3D buffers.
Presenters: Tom Watson and Michael Martin

Landscape Disturbance Related to Natural Gas Extraction in the Mid-Atlantic Region -- May 23, 2014
Increased demands for cleaner burning energy, coupled with the relatively recent technological advances in accessing unconventional hydrocarbon-rich geologic formations, have led to an intense effort to find and extract natural gas from various underground sources around the country. One of these sources, the Marcellus Shale, located in the Allegheny Plateau, is currently undergoing extensive drilling and production. The technology used to extract gas in the Marcellus shale is known as hydraulic fracturing and has garnered much attention because of its use of large amounts of fresh water, its use of proprietary fluids for the hydraulic-fracturing process, its potential to release contaminants into the environment, and its potential effect on water resources. Nonetheless, development of natural gas extraction wells in the Marcellus Shale is only part of the overall natural gas story in the area of Pennsylvania. Coalbed methane, which is sometimes extracted using the similar technique, is commonly located in the same general area as the Marcellus Shale and is frequently developed in clusters across the landscape. The combined effects of these two natural gas extraction methods create potentially serious patterns of disturbance on the landscape. This presentation quantifies the landscape changes and consequences of natural gas extraction for the natural gas play in Pennsylvania between 2004 and 2010. Patterns of landscape disturbance related to natural gas extraction activities were collected and digitized using National Agriculture Imagery Program (NAIP) imagery for 2004, 2005/2006, 2008, and 2010. The disturbance patterns were then used to measure changes in land cover and land use using the National Land Cover Database (NLCD) of 2001 as a baseline. A series of landscape metrics are also used to quantify these changes and report on the potential ecosystem effects.

Terrestrial and Aerial Lidar for the Measurement and Monitoring of Forest Ecosystem Services -- June 27, 2014
Ecosystem services can be categorized into: provision, regulating, supporting, preserving and cultural services. All of these amenities can be attributed to forested environments and are becoming a targetable issue for sustainable management of these resources. Because field studies represent only a snapshot in the spatiotemporal continuum of a landscape, remote sensing can assist with spatially explicit modeling at a site, watershed and landscape levels. Although, a wide array of remote sensing approaches for ecosystem assessment has been developed over decades, these are applicable to imaging satellite datasets, and come with limitations related to the resolution and lack of spatial (and three dimensional in the case of forests) detail. It is with the onset of lidar and our ability to capture the detailed and even leaf level structure of the forested landscape that remote sensing of ecosystem services has become feasible. This talk will focus on providing examples of provision services mapping, such as biomass and cellulosic biofuels estimation. Regulatory services will be explored through examples of detailed modeling of forests in the Pacific Northwest applied to a variety of purposes, including the close study of the riparian forest/water interface and function for the suitability and sustainability of salmon habitat. Preserving services related to biodiversity, habitat and accounting for uncertainty will also be addressed through examples of monitoring forested wetlands on Mt. Rainier, Washington. The study extends beyond the suitability of habitat toward the ecosystem services of the forest for quality drinking water. Finally, discussion on how supporting and cultural services, such as pest/disease control and recreational opportunities, can also be addressed with lidar remote sensing will be provided.

An Overview of Considerations and Methodologies for High Resolution Land Cover Mapping -- July 25, 2014
With the vast increase in access to commercially available high spatial resolution imagery over the past 10 years, there has also been a surge in the demand for more spatially detailed land cover data. The Coastal Change Analysis Program (C-CAP) produces nationally standardized high resolution land cover and land change information for selected coastal geographies of the U.S. derived from high resolution imagery acquired by satellite and aerial platforms. C-CAP high resolution products provide a spatially detailed inventory of coastal intertidal areas, wetlands, and adjacent uplands, with a goal of monitoring these habitats by updating the land cover maps every five years. This seminar will draw from the experiences of C-CAP over the past eight years to provide attendees with a summary of the elements and challenges related to high spatial resolution mapping projects. Topics will include planning and data acquisition, data integration, classification, and change detection
