| Data Access: GIS and Web Services |

| Description | What does "data access" mean for the GIS community? GIS tools such as ArcGIS Online, MapServer web services, and GeoPlatform allow users to "access" (explore and visualize) GIS datasets in a fundamentally different way from the more traditional NCEI archives (e.g., buoy data). We would like to invite the NOAA GIS community to discuss "access" to geospatial data and products, and we suggest that while archiving these data at NCEI is important for longterm preservation, commonly used geospatial tools and resources are ultimately what provides practitioners the data and information they need to conduct their work.What does "data access" mean for the GIS community?

| 3C.1 | The NOAA View Portal: streamlining development and access via Esri software
Dan Pisut (NESDIS/Visualization Lab) Tim Loomis (NESDIS), Vivek Goel (NESDIS) |
||
| Developed four years ago as an educational data exploration tool, NOAA View has undergone significant upgrades of its backend over the past year. Now built on Esri ArcGIS Server and Portal and hosted by the Visualization Lab, the NOAA View Portal hosts around 200 data services, mostly tiled or cached images, a series of story maps being developed by contributors from across NOAA and its external partners, web applications, and other utilities. This demonstration will walk through some of NOAA View Portal’s offerings, while also discussing future plans for the system, along with how others may access or contribute to these services. | |||
| 3C.2 | Can I Weather My Map?
Nipa Parikh (NWS/Office of Dissemination) Donald Rinker |
||
| NOAA portfolio of geospatially enabled highly available (7x24) products is growing rapidly. This portfolio of geospatial
web services is part of the larger Integrated Dissemination Program (IDP), a major consolidation and update of existing
NOAA dissemination systems with a large focus on weather and environmental decision support systems. Increasing
the reliability and support of delivering weather information as Geographic Information Systems (GIS) services was
one of the objectives of IDP. The IDP GIS projects included migrating nowCOAST services and application to the IDP
virtual machine infrastructure and consolidating existing NWS geospatial services to a fully supported dissemination
infrastructure. As a result of the implementation of these systems, over 200 NOAA products are available as geospatial
map services. Some of the data included in these services are current NWS hazardous weather watches, warnings,
and advisories; NESDIS’ GOES cloud imagery; NOS’ nautical charts; NOS’ Environmental Sensitivity Index; and
National Marine Fisheries Service’s (NMFS) Essential Fish Habitat data. Geospatial data clients can access maps of
NOAA data and products as REST map services (some time-enabled), OGC compliant Web Map Services, and KML.
IDP GIS continues to work to keep our infrastructure technology up to date while increasing the available products and application functionality. 2017 is an exciting year for the projects, as we all know the weather and coasts continually change, so IDP GIS is working on the best way to deliver time dependent products, incorporate advances in technology to better handle scientific data, and expand the available OGC compliant data formats. Additionally IDP GIS product suite will be expanded to include Sea, Lake, and Overland Surges from Hurricane (SLOSH) data, restructured NWS tropical services, and NDGD air quality data. This talk will focus on data access best practices, challenges, and future plans with time for you to provide feedback and suggestions for how IDP GIS can better serve your geospatial needs. |

| 3C.3 | DEMO: Making Web Services Discoverable
Jacqueline Mize (NESDIS/NCEI) Katharine Weathers (NCEI), David Moffitt (NCEI) |
||
| Many powerful and useful web services such as ERDDAP and ArcGIS map services often go undiscovered. This demonstration will feature how NCEI has utilized ISO metadata and ESRI Geoportal software to provide discoverability and access to various web services created for archived data. | |||
| 3C.4 | Map Services: A Two Way Flow of Data
Ken Buja (NOS/NCCOS) |
||
| NCCOS has been publishing map services for use in a number of applications not only to share our data with the public, but to also gather data from the public. In addition to publishing services with IDP and NCEI using ArcGIS Server, we have published several on the NOAA GeoPortal to create editable feature services. This talk will cover the use of map services in three different types of projects. The first is a simple data viewer using Esri’s Web AppBuilder with a map service utilizing a complex nested grouping structure. The second is a custom-built application to showcase benthic habitat data and imagery in dynamic and tiles map services, as well as external video photography. The final project is a custom-built application that uses a NOAA GeoPortal feature service that gives users the ability to edit existing data. | |||
| 3C.5 | Geospatial workflows and processes used to develop and visualize the United States’ Extended Continental Shelf
Finn Dahl (NESDIS/CIRES) Barry Eakins (CIRES), Jennifer Jencks (NCEI), Erin LeFevre (CIRES) Elliot Lim (CIRES), Jesse Varner (CIRES) |
||
| The U.S. Extended Continental Shelf (ECS) Project is a multi-agency collaboration to establish the full extent of the continental shelf of the United States, beyond 200 nm, consistent with international law. The process to determine this new maritime outer limit requires the collection and analysis of data that describe the depth, shape, and geophysical characteristics of the seabed and sub-sea floor. In 2014, the ECS Project Office, led by the Department of State, was established at NOAA’s National Centers for Environmental Information (NCEI) in Boulder, Colorado to efficiently and effectively guide the U.S. ECS Project to completion and final documentation. As a process for formulating the GIS documentation requirements, the ECS GIS team is developing a geospatial database used for stewarding project specific assets, analyzing over 30 ECS-funded cruises that collected a variety of marine geophysical data (>2 million km² of bathymetric data, along with seismic, geological samples, magnetic and gravity data), generating nearly 1000 maps, profiles, illustrations, and figures, storing ECS maritime boundary delineation products into the NCEI archive, and sharing ECS bathymetric and analytical products using custom web mapping services. We will describe how cutting-edge analytical geospatial software, custom python driven automation tools, and collaborative web technologies come together in order to meet demands of the project, and how those technologies may be extended beyond the project. | |||
| 3C.6 | ERMA as an OGC web service catalog
Robb Wright (NOS/OR&R / ERMA) Jay Coady (NOS/OR&R) |
||
| NOAA’s Office of Response and Restoration’s Environmental Response Management Application (ERMA) is an online open-source-based mapping application providing centralized access and visualization of integrated data. Thousands of data layers are visible within ERMA. The data comes from a variety of sources, including federal, state and local governments, along with NGOs and partner companies. OGC connections are available and visible for all layers, with ERMA providing local WMS links for data held locally as well as remote WMS links for data being brought in from external web services. ERMA’s tiered security structure allows for data to be secured behind logins, and ERMA has recently made these secured data layers available through a tokenized access system for partners who need quick and easy access to data in ERMA without requiring them to download and duplicate data sources. These full web references to local ERMA data or remote data services ensure that end-users are able to find and connect to all data viewable in ERMA. | |||
