Knowra Geomatics Geomatics Geomatics is the discipline of acquiring, analyzing, managing, and communicating spatial data. It combines methods such as surveying, remote sensing, and geographic information systems.
Photogrammetry : The extraction of measurements and three-dimensional information from photographs. Overlapping images can yield mapped features and terrain models.
Cadastral surveying : The measurement and recording of land parcels, boundaries, and property interests. Geomatics methods establish and maintain authoritative parcel maps.
History of surveying : The development of techniques and instruments for measuring land and determining positions. Geomatics inherits a long tradition of systematic land measurement.
Geography : The study of places, environments, and relationships between people and Earth’s surface. Geography investigates spatial phenomena broadly, while geomatics emphasizes spatial data methods.
LiDAR : A remote-sensing method that measures distance with laser pulses and their returned signals. Laser ranging produces dense three-dimensional observations of surfaces.
Earth observation : The collection of information about Earth’s surface and atmosphere, commonly by satellite or aircraft. It applies geomatics techniques to monitor broad environmental and human changes.
Triangulation : A surveying method that determines positions from measured angles in a network of triangles. Triangulation enabled large-area control surveys before satellite positioning.
Geoinformatics : The computational study and development of methods for handling geographic information. It overlaps strongly with geomatics but centers more explicitly on information science and computation.
Coordinate reference system : A framework that defines how coordinates correspond to locations on Earth. It makes measured positions interpretable and comparable across datasets.
Urban planning : The process of shaping land use, infrastructure, and development in towns and cities. Spatial datasets help planners assess growth, access, and competing land uses.
