Thread: Applications of GPS and GIS in Civil Engineering

Popular topic for study

Marine or ocean ecosystem

These ecosystems are different from freshwater ecosystem mainly because of its salty water. Marine ecosystems are among the Earth's aquatic ecosystems. They include: Oceans, Estuaries and Lagoons, Mangroves and Coral reefs, the Deep Sea and the Sea floor. These are the gigantic reservoirs of water covering approximately 71% of the Earth's surface (an area of some 361 million square kilometers). The salt concentration in an open sea is usually 3.5% (35 parts per thousand (ppt)). Dominant ions are sodium & chloride. Average temperature of Marine ecosystem is 2-3 degree centigrade, devoid of light Read this topic

    Pdf 32 Applications of GPS and GIS in Civil Engineering

    Geographic Information Technologies

    • Global Positioning Systems (GPS)
    – A system of Earth-orbiting satellites which provides precise location on the earth’s surface in lat./long coordinates.
    – 11 hours 58 minutes orbital period
    – 24 hour 3D coverage worldwide

    • Remote Sensing (RS)
    – Use of satellites/aircrafts to capture info-earth’s surface.
    – Digital ortho images a key product.

    • Geographic Information Systems (GIS)
    – Computer-based Technology
    – Designed with software, hardware, data, procedure, network and live ware.
    – Storage, retrieval, mapping and analysis of geographic data.
    – Data is stored in coordinate form.
    – Layered together for mapping analysis.
