Web Services

We deliver catalogs, maps, and data through standard programmatic interfaces:

1. Open Geospatial Consortium (OGC) WxS Services.

   Our Web Map Service (WMS) allows any OGC-enabled client to create map imagery from our global multi-resolution topography synthesis. Specify this URL to your client -

   http://www.marine-geo.org/services/wms?request=GetCapabilities&service=WMS&version=1.1.1

   Our Web Feature Service (WFS) allows any OGC-enabled client to access our global catalog of station events (cores and dredges, camera tows, CTD stations, instrument deployments, etc.) and physical samples (biology, rock, sediment, fluid). Specify this URL to your client -

   http://www.marine-geo.org/services/wfs?request=GetCapabilities&service=WFS&version=1.0.0

   We are also developing a Web Coverage Service (WCS) to provide access to raster data sets, and a Web Terrain Service (WTS) to provide three-dimensional perspective scenes.

   We use the MapServer software platform as our backend.

A variety of OGC-enabled clients are available, both freeware and commercial, including the User-Friendly Desktop Internet GIS (uDig), GeoMapApp, Gaia, NASA World Wind, and ArcGIS.



2. Catalog Services. We offer simple REST-type (read more) services to directly query our repository in real-time.

a.) Our "getVocabulary" service exposes a specified controlled vocabulary -

http://www.marine-geo.org/services/getVocabulary/?id=XXX where XXX is one of


bio_genus_id
bio_species_id
country_id
data_type
device_id
device_type
entry_id
entry_type
feature_id
feature_type
format_id
gridsystem_id
initiative_id
language_id
launch_type
line_platform_type
location_id
nav_type
organization_id
person_id
platform_id
platform_type
role_id
role_type
srs_id
station_platform_type
station_type
status_id
unit_id


b.) Our "getCollection" service returns metadata for the specified collection (entry_id above) as a XML record -

http://www.marine-geo.org/services/getCollection/?id=XXX

c.) Our "getDataSet" service delivers a specified set of data files as a TAR package -

http://www.marine-geo.org/services/getDataSet/?collection=X&device=Y&quality=Z where
X = entry_id
Y = device_type
Z = 0,1,2,...



3. Open Archives Initiative Protocol for Metadata Harvest (OAI-PMH).

Our OAI-PMH service provides NOAA Metadata Manager Repository (NMMR)-compliant FGDC metadata records for our multibeam data sets. You may explore and harvest records here -

We use the DLESE jOAI software platform as our backend.
