Hydrography is the branch of applied sciences which deals with the measurement and description of the physical features of oceans, seas, coastal areas, lakes and rivers, as well as with the prediction of their change over time, for the primary purpose of safety of navigation and in support of all other marine activities, including economic development, security and defense, scientific research, and environmental protection.
The World Geodetic System (WGS) is a standard used in cartography, geodesy, and satellite navigation including GPS. The current version, WGS 84, defines an Earth-centered, Earth-fixed coordinate system and a geodetic datum, and also describes the associated Earth Gravitational Model (EGM) and World Magnetic Model (WMM). The standard is published and maintained by the United States National Geospatial-Intelligence Agency.
The National Geospatial-Intelligence Agency (NGA) is a combat support agency within the United States Department of Defense whose primary mission is collecting, analyzing, and distributing geospatial intelligence (GEOINT) in support of national security. Initially known as the National Imagery and Mapping Agency (NIMA) from 1996 to 2003, it is a member of the United States Intelligence Community.
A hydrographic office is an organization which is devoted to acquiring and publishing hydrographic information.
Geomatics is defined in the ISO/TC 211 series of standards as the "discipline concerned with the collection, distribution, storage, analysis, processing, presentation of geographic data or geographic information". Under another definition, it consists of products, services and tools involved in the collection, integration and management of geographic (geospatial) data. Surveying engineering was the widely used name for geomatic(s) engineering in the past. Geomatics was placed by the UNESCO Encyclopedia of Life Support Systems under the branch of technical geography.
The Canadian Hydrographic Service (CHS) is part of the federal department of Fisheries and Oceans Canada and is Canada's authoritative hydrographic office. The CHS represents Canada in the International Hydrographic Organization (IHO).
Bathymetry is the study of underwater depth of ocean floors, lake floors, or river floors. In other words, bathymetry is the underwater equivalent to hypsometry or topography. The first recorded evidence of water depth measurements are from Ancient Egypt over 3000 years ago.
Geoinformatics is a scientific field primarily within the domains of Computer Science and technical geography. It focuses on the programming of applications, spatial data structures, and the analysis of objects and space-time phenomena related to the surface and underneath of Earth and other celestial bodies. The field develops software and web services to model and analyse spatial data, serving the needs of geosciences and related scientific and engineering disciplines. The term is often used interchangeably with Geomatics, although the two have distinct focuses; Geomatics emphasizes acquiring spatial knowledge and leveraging information systems, not their development. At least one publication has claimed the discipline is pure computer science outside the realm of geography.
The United Kingdom Hydrographic Office (UKHO) is the UK's agency for providing hydrographic and marine geospatial data to mariners and maritime organisations across the world. The UKHO is a trading fund of the Ministry of Defence (MoD) and is located in Taunton, Somerset, with a workforce of approximately 900 staff.
Geoscience Australia is a statutory agency of the Government of Australia that carries out geoscientific research. The agency is the government's technical adviser on aspects of geoscience, and serves as the repository of geographic and geological data collated by the Commonwealth.
The following outline is provided as an overview of and topical guide to cartography:
The Hawaii Department of Land and Natural Resources (DLNR) is a part of the Hawaii state government dedicated to managing, administering, and exercising control over public lands, water resources and streams, ocean waters, coastal areas, minerals, and other natural resources of the State of Hawaiʻi. The mission of the Hawaiʻi Department of Land and Natural Resources is to "enhance, protect, conserve and manage Hawaiʻi's unique and limited natural, cultural and historic resources held in public trust for current and future generations of the people of Hawaiʻi nei, and its visitors, in partnership with others from the public and private sectors." The organization oversees over 1.3 million acres of land, beaches, and coastal waters and 750 miles of coastal land.
GeoBase is a federal, provincial and territorial government initiative that is overseen by the Canadian Council on Geomatics (CCOG). It is undertaken to ensure the provision of, and access to, a common, up-to-date and maintained base of quality geospatial data for Canada. Through the GeoBase, users with an interest in geomatics have access to quality geospatial information at no cost and with unrestricted use.
Ramón Jesús Palmiano Paje is a Filipino civil servant. He was the 19th secretary of the Department of Environment and Natural Resources (DENR) under the administration of President Benigno Aquino III. Prior to his appointment, he was DENR Undersecretary for Field Operations and Executive Director of the Minerals Development Council under the Office of the President in concurrent capacity.
USNS John McDonnell (T-AGS-51) was a hydrographic survey ship operated by the Military Sealift Command (MSC) with a contract crew for the Naval Oceanographic Office which assigned a military and civilian hydrographic detachment to conduct coastal surveys. The ship and its sister, USNS Littlehales (T-AGS-52), were replacements for the coastal hydrographic survey vessels USNS Chauvenet (T-AGS-29) and USNS Harkness (T-AGS-32).
National Natural Resources Management System is an integrated natural resource management system of India which aggregates the data about natural resources from the remote sensing satellites and other conventional techniques. One of the important elements of this management system is the National Resource Information Systems which acts as feeder information system to the larger information system of the Government, which includes socioeconomic information and models. NNRMS activities are co-ordinated at the National level by the Planning Committee of NNRMS (PC-NNRMS) which frames guidelines for implementation of the systems and oversees the progress of remote sensing applications for natural resources management in the country.
Lieutenant General Howard W. Penney of United States Army, was first director of Defense Mapping Agency from July 1972 to August 1974. Under Penney's leadership, the new agency focused its assets into a decentralized structure with a lean staff to respond to the rising demands for geographic information by a variety of military users.
The Hydrographic Institute of the Republic of Croatia is a government agency responsible for providing hydrographic and marine geospatial data for the Republic of Croatia. The institute is located in Split, and covers scientific research and development, services related to the safety of navigation, the hydrographic-geodetic survey of the Adriatic sea, marine geodesy, design and publication of nautical charts and books, oceanographic research, and submarine geology research. The Croatian Hydrographic Institute is responsible for the development of navigational safety service in the Adriatic, within the worldwide navigational safety system, and in cooperation with the Ministry of the Sea, Transport and Infrastructure, port authorities, the Croatian Navy, lighthouse authorities, and hydrographic offices of all maritime countries, following internationally agreed standards.
