  2. TERCOM - Wikipedia

    en.wikipedia.org/wiki/TERCOM

    This produces a location and direction. The guidance system can then use this information to correct the flight path of the missile. [citation needed] During the cruise portion of the flight to the target, the accuracy of the system has to be enough only to avoid terrain features. This allows the maps to be a relatively low resolution in these ...

  3. Image rectification - Wikipedia

    en.wikipedia.org/wiki/Image_rectification

    Image rectification in GIS converts images to a standard map coordinate system. This is done by matching ground control points (GCP) in the mapping system to points in the image. These GCPs calculate necessary image transforms. [11] Primary difficulties in the process occur when the accuracy of the map points are not well known

  4. Universal Transverse Mercator coordinate system - Wikipedia

    en.wikipedia.org/wiki/Universal_Transverse...

    The Universal Transverse Mercator (UTM) is a map projection system for assigning coordinates to locations on the surface of the Earth.Like the traditional method of latitude and longitude, it is a horizontal position representation, which means it ignores altitude and treats the earth surface as a perfect ellipsoid.

  5. Georeferencing - Wikipedia

    en.wikipedia.org/wiki/Georeferencing

    Georeferencing or georegistration is a type of coordinate transformation that binds a digital raster image or vector database that represents a geographic space (usually a scanned map or aerial photograph) to a spatial reference system, thus locating the digital data in the real world.

  6. What3words - Wikipedia

    en.wikipedia.org/wiki/What3words

    What3words (stylized as what3words) is a proprietary geocode system designed to identify any location on the surface of Earth with a resolution of about 3 metres (9.8 ft). It is owned by What3words Limited, based in London, England. The system encodes geographic coordinates into three permanently fixed

  7. Simultaneous localization and mapping - Wikipedia

    en.wikipedia.org/wiki/Simultaneous_localization...

    2005 DARPA Grand Challenge winner Stanley performed SLAM as part of its autonomous driving system. A map generated by a SLAM Robot. Simultaneous localization and mapping (SLAM) is the computational problem of constructing or updating a map of an unknown environment while simultaneously keeping track of an agent's location within it.

  8. Map projection - Wikipedia

    en.wikipedia.org/wiki/Map_projection

    Distance from the tangent point on the map is proportional to straight-line distance through the Earth: r(d) = c sin ⁠ d / 2R ⁠ [38] Logarithmic azimuthal is constructed so that each point's distance from the center of the map is the logarithm of its distance from the tangent point on the Earth.

  9. Space mapping - Wikipedia

    en.wikipedia.org/wiki/Space_mapping

    The space mapping concept has been extended to neural-based space mapping for large-signal statistical modeling of nonlinear microwave devices. [9] [10] Space mapping is supported by sound convergence theory and is related to the defect-correction approach. [11] A 2016 state-of-the-art review is devoted to aggressive space mapping. [12]
