Summary

The purpose of this project was to support the enhanced search, access, and visualization capability for disaster maps and other contributed products on the public USGS Hazards Data Distribution System (HDDS) (U.S. Geological Survey, 2015). These products are often provided to USGS by collaborators for sharing across the response community during the course of an emergency event response; however, in the past, they were not easy for users to discover or access. This project involved the design, testing, and delivery of a new capability for HDDS to ingest, catalog, and display informational or value-added products when provided in a variety of formats. As a result of this work, the user community will be able to interactively search, [...]

Summary

The purpose of this project was to support the enhanced search, access, and visualization capability for disaster maps and other contributed products on the public USGS Hazards Data Distribution System (HDDS) (U.S. Geological Survey, 2015). These products are often provided to USGS by collaborators for sharing across the response community during the course of an emergency event response; however, in the past, they were not easy for users to discover or access. This project involved the design, testing, and delivery of a new capability for HDDS to ingest, catalog, and display informational or value-added products when provided in a variety of formats. As a result of this work, the user community will be able to interactively search, preview, and access these products alongside the remotely sensed imagery (satellite and aerial photography) already available through the HDDS interface.

The HDDS is a public USGS-hosted Web portal that provides a consolidated point-of-entry and distribution system for remotely sensed imagery and other geospatial datasets related to emergency response. When disasters occur, the system provides a critical source of satellite and aerial imagery for the emergency response community. The imagery and datasets on HDDS include imagery collected by USGS as well as contributed datasets from many other government agencies and collaborators. After ingest, the HDDS-hosted imagery is accessed by end users from all levels of government (Federal, state, local, tribal, and international) as well as many other organizations and communities engaged in emergency event support. This project supported the expansion HDDS ingest capabilities to include user-contributed maps and other value-added products, allowing them to be more easily shared, discovered, visualized, and accessed by the user community.

With system and software developments supported by CDI, the HDDS now includes the capability to ingest, catalog, and display maps and other information products provided by data contributors. The newly supported product types include image-based maps in the form of Portable Document Format (PDF), Joint Photographic Experts Group (JPEG), Motion Pictures Expert Group (MPEG), Tagged Information File (TIF), and Microsoft Word files as well as vector products such as Keyhole Markup Language (KML) and shapefiles .

Along with the HDDS system development, a supporting document (“HDDS Product Specifications and Services”) was created to provide technical guidance for data contributors and collaborators seeking to share their products via HDDS (Gacke, 2015b). This document provides the detailed product and metadata specifications (format, file naming, and more) required to support HDDS ingest along with data transfer instructions and requirements.

As a result of these CDI-funded activities, the contributed maps and other products can be more easily shared across the emergency response community. For any ingested product, the user community is now able to interactively search, preview, and access the map products directly through the existing map-based HDDS interface (fig. 22).

Accomplishments

Technical Document.—The “HDDS Product Specifications and Services Document” was developed to provide detailed information and guidance on acceptable product format(s), metadata requirements, and other supporting information for contributors of incoming products. The document also provides detailed instructions for product transfer to the USGS and HDDS systems. As of October 30, 2015, the specification document has been finalized and is now available for distribution to cooperators and contributors.
HDDS Ingest and Archive Software.—The internal HDDS system capability was modified to support map product ingest, including metadata extraction and browse/thumbnail image creation. The metadata, browse, and ingested products are placed into the existing HDDS system catalog for potential access by end users.
Web-Based Search/Query and Display.—User discovery and visualization of disaster maps and other products are now supported by the HDDS Web interface at http://hddsexplorer.usgs.gov/ and presented to the end user in a fully integrated manner alongside other available image datasets. The system now allows user-defined search queries, metadata display, graphical visualization on a map background, and full download options according to image license/access provisions.
