Geospatial in the context of Geographic databases

Null Island is the location at zero degrees latitude and zero degrees longitude (0°N 0°E / 0°N 0°E / 0; 0), i.e., where the prime meridian and the equator intersect. Since there is no landmass located at these coordinates, it is not an actual island. The name is often used in mapping software as a placeholder to help find and correct database entries that have erroneously been assigned the coordinates 0,0. Although "Null Island" started as a joke within the geospatial community, it has become a useful means of addressing a recurring issue in geographic information science.

In the United States, geospatial intelligence (GEOINT) is intelligence about the human activity on Earth derived from the exploitation and analysis of imagery, signals, or signatures with geospatial information. GEOINT describes, assesses, and visually depicts physical features and geographically referenced activities on the Earth. GEOINT, as defined in US Code, consists of imagery, imagery intelligence (IMINT) and geospatial information.

Today, GEOINT knowledge and tradecraft are not confined to the U.S. government, or even the world's leading military powers. Additionally, countries such as India are holding GEOINT-specific conferences. While other countries may define geospatial intelligence somewhat differently than does the U.S., the use of GEOINT data and services is the same.

Intermap Technologies (TSX: IMP) is a publicly traded company headquartered in Douglas County, Colorado, United States. Intermap provides geospatial solutions that allow GIS professionals in commercial and government organizations worldwide to build a broad range of applications. Industries such as energy, engineering, government, risk management, telecommunications, water resource management, and automotive use Intermap’s NEXTMap 3D terrain products and geospatial services.

The Open Geospatial Consortium (OGC) is an international voluntary consensus standards organization that develops and maintains international standards for geospatial content and location-based services, sensor web, Internet of Things, GIS data processing and data sharing. The OGC was incorporated as a not for profit in 1994. At that time, the official name was the OpenGIS Consortium. It is a U.S.-registered 501c(6) non-profit with offices in Belgium and the U.K. Commercial, government, nonprofit, universities, and research organizations from around the world participate in a consensus process encouraging development, maintenance, and implementation of open standards.

Geodesy or geodetics is the science of measuring and representing the geometry, gravity, and spatial orientation of the Earth in temporally varying 3D space. It is called planetary geodesy when studying other astronomical bodies, such as planets or circumplanetary systems. Geodetic job titles include geodesist and geodetic surveyor.

Through highly accurate observations, geodesy provides the scientific basis for mapping, navigation, and positioning, and supports applications such as infrastructure development (including construction), natural resource management, mineral exploration, and geophysics. Its measurements underpin modern geospatial reference frames used in transportation, satellite systems, global trade, and timekeeping.

OpenSeaMap is a software project collecting freely usable nautical information and geospatial data to create a worldwide nautical chart. This chart is available on the OpenSeaMap website, and can also be downloaded for use as an electronic chart for offline applications.

The project is part of OpenStreetMap. OpenSeaMap is part of the OpenStreetMap database, and complements the spatial data with nautical information. Such data may be used in accordance with the Open Database License. This ensures integration into printed materials, websites and applications is possible, without being limited by restrictive licenses, or having to pay fees.
