GIS for Environmental, Community and Public Health
Tuesday March 6, 2012 - 10:45 am to noon
The Hawaii State Department of Health's Environmental Health Administration (EHA) has made great strides with GIS and geospatial technologies in recent years. EHA has integrated GIS capabilities into several applications to enhance finding and viewing environmental information across the state. We will showcase three separate systems developed at EHA that utilize GIS and geospatial tools.
EHA implemented an Environmental Health Warehouse in late 2009. This warehouse extracts information from the administration's environmental and health systems, reconciles the points of interest, and presents a holistic view of the data to consumers. A spatial inquiry system is used to find and explore known environmental information within locations and areas.
The Safe Drinking Water Branch designed and implemented a custom map viewer application, providing county and environmental health specialists ways to query water system, facility and sample point information. The solution also provides field users with a way to improve locational data with GPS-collected coordinates using custom mobile software on Trimble handheld devices.
The Clean Water Branch (CWB) created a custom water quality data viewer that gives internal and external users access to water quality data and beach warnings, advisories and postings. The system also includes a mapping utility that helps the CWB quickly and easily define affected locations and areas.
EHA has integrated ArcGIS Server technologies into many of its systems available inside and outside of the organization, often overlaying ArcGIS server layers over GoogleMaps as well as deriving geopolitical data to enhance the search capabilities of its inquiry tools.

An Overview of the National Hydrography Dataset
Malie Beach-Smith

Honolulu, HI
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.

CCH-DPP Storm Water Application
Brian Loomis
Hi-Tech Urban Solution, Inc., Honolulu, HI
Engineering and Public Works
Wednesday March 7, 2012 - 10:45 am to noon
The City & County of Honolulu's Storm Water Application is a web-based GIS application that delivers powerful mapping, network tracing, and data access tools to users throughout the City. It is the culmination of a multi-year, collaborative effort by the City's Department of Planning and Permitting to improve the coverage, accuracy, and dissemination of its storm water-related GIS data. The application is designed around NPDES permit obligations the City is required to meet. The application is a completely custom ArcGIS Server Web ADF implementation. It is programmed in ASP.NET/VB.NET, incorporates custom ArcObjects modules, and integrates multiple City SQL data servers. The presentation will discuss (1) the user-interviews and NPDES requirements driving the design process, (2) the application's capabilities and toolsets, (3) a high-level review of its technical architecture, and (4) lessons learned. The presentation will also include a live demo (subject to internet access and technical support).
