We continue to issue Data DOIs for data sets curated by MGDS. Data DOIs not only enable direct linking of scientific publications with supporting data, but since they enable the citation of data, they are becoming an important metric of scientific impact. As of October, data DOIs have been issued for more than 1,000 data sets.

July 2014

Map interfaces throughout the MGDS website now show geospatial extent of data sets and, for geo-located images such as bottom photos, allow users to interact with the data by browsing individual images in map-view and linking to full-resolution image downloads. Examples of the new map interfaces are given here and here.

An improved version of GMRT MapTool was launched. It provides better map image performance, a new pan-and-zoom full-browser map interface, additional format options (GeoTIFF, ArcASCII) and more choices of resolution for downloading GMRT grids.

GeoMapApp 3.0 and GMRT 2.0 released! GeoMapApp 3.0 provides access to a major upgrade to the base topography dataset accessible through GeoMapApp to include the GMRT 2.0, with greatly expanded coverage in the oceans, and the ASTER and NED topography datasets for the global land masses. The ASTER GDEM topography dataset (Japan METI/NASA), provides 30 m resolution for the continents from 83°S to 83°N and replaces the SRTM dataset used in prior GeoMapApp releases. For North America, the even higher resolution NED dataset (USGS) is now accessible, providing topography of the continental U.S. to 10 m resolution. For the oceans, the GMRT v2.0 synthesis includes bathymetric coverage to 100 m resolution from multi-beam bathymetry mapping expeditions and regional gridded compilations from a number of areas and international sources. New data coverage over GMRT 1.0 is focused in the Atlantic and central Pacific with over 100 expeditions added since the prior release. In addition, GMRT v2.0 includes a new 50 m grid resolution layer for the continental shelves and other ocean areas where native resolution of the available sonar data is sufficient. The high resolution bathymetry are merged with the Smith and Sandwell v12.1 global topography compilation, the IBCAO v2.23 for the Arctic, and the BedMap Subglacial Topographic Model of the Antarctic.

Statistics showing the use of GeoMapApp Custom Portals since 2004 are now available.
