GeoEye Satellite

Google mendapatkan hadiah ulang tahun yang ke-10 berupa peluncuran satelit yang bernama GeoEye-1. Peluncuran tersebut hanya berselang sehari menjelang ulang tahun Google. Di harapkan dengan di luncurkan GeoEye-1, Google dapat menambahkan data-data peta satelit dari seluruh dunia. Satelit GeoEye-1 diluncurkan dengan menumpang roket Delta II di tempat peluncuran Vandenberg Air Force Base.

What Are LIDAR Data?

Light Detection and Ranging (LIDAR) is a remote sensing system used to collect topographic data. This technology is being used by the National Oceanic and Atmospheric Administration (NOAA) and NASA scientists to document topographic changes along shorelines. These data are collected with aircraft-mounted lasers capable of recording elevation measurements at a rate of 2,000 to 5,000 pulses per second and have a vertical precision of 15 centimeters (6 inches). After a baseline data set has been created, follow-up flights can be used to detect shoreline changes.

How LIDAR Data Are Collected

For the South Carolina project, a LIDAR sensor was mounted on-board a NOAA DeHavilland Twin Otter aircraft pictured below. Once in flight, the aircraft travels over the beach at approximately 60 meters per second. During the flight, the LIDAR sensor pulses a narrow, high frequency laser beam toward the earth through a port opening in the bottom of the aircraft’s fuselage. The LIDAR sensor records the time difference between the emission of the laser beam and the return of the reflected laser signal to the aircraft.

Geomatics is the discipline of gathering, storing, processing, and delivery of geographic information, or spatially referenced information.


Geomatics is fairly new, the term was apparently coined by B. Dubuisson in 1969. It includes the tools and techniques used in land surveying, remote sensing, Geographic Information Systems (GIS), Global Navigation Satellite Systems (GPS, GLONASS, GALILEO, COMPASS), and related forms of earth mapping.

Originally used in Canada, because it is similar in French and English, the term geomatics has been adopted by the International Organization for Standardization, the Royal Institution of Chartered Surveyors, and many other international authorities, although some (especially in the United States) have shown a preference for the term geospatial technology.

International Society for Photogrammetry and Remote Sensing (ISPRS)

International Society for Photogrammetry and Remote Sensing

In 1910, the International Society for Photogrammetry (ISP) was founded under the leadership of its first President, Eduard Dolezal, from Austria. After 70 years of functioning under its original name, the Society changed its name in 1980 to the International Society for Photogrammetry and Remote Sensing (ISPRS).

Photogrammetry and Remote Sensing is the art, science, and technology of obtaining reliable information from noncontact imaging and other sensor systems about the Earth and its environment, and other physical objects and processes through recording, measuring, analyzing and representation.
