GNSS SURVEYS

GNSS (Global Navigation Satellite System) surveys is a satellite based measuring system that is used to pinpoint the geographic location of a user's receiver anywhere in the world.

Geographic Information Systems

Geographic Information Systems is a computer-based tool that analyzes, stores, manipulates and visualizes geographic information, usually stored in digital format. Geographic Information Systems really comes down to just 4 simple ideas:

  • Create geographic data
  • Manage it
  • Analyze it and
  • Display it on a map.

Remote Sensing

Remote sensing is the art and science of making measurements of the earth using sensors on airplanes or satellites. These sensors collect data in the form of images and provide specialized capabilities for manipulating, analyzing, and visualizing those images. Remote sensed imagery is integrated within a GIS.

Laser scanning

Laser scanning Laser Scanning or LIDAR (Light Detection and Ranging) is the process of shining a reflectorless laser line over a surface in order to collect 3-dimensional data. The surface data is captured by a camera sensor mounted in the laser scanner, which records accurate dense 3D points in space.

Airborne Laser Scanning

Terrestrial Laser Scanning

Aerial photogrammetry

Aerial photography (or airborne imagery) is the taking of photographs from an aircraft or other flying object. Platforms for aerial photography include fixed-wing aircraft, helicopters, unmannedaerial vehicles (UAVs or "drones"), balloons, blimps and dirigibles, rockets, pigeons, kites, parachutes, stand-alone telescoping and vehicle-mounted poles.

Digital photogrammetry

UAV photogrammetry

Hydrographic Surveys

Hydrographic survey is the science of measurement and description of features, which affect maritime navigation, marine construction, dredging, offshore oil exploration/offshore oil drilling and related activities. Strong emphasis is placed on soundings, shorelines, tides, currents, seabed and submerged obstructions that relate to the above mentioned activities. The term hydrography is used synonymously to describe maritime cartography, which in the final stages of the hydrographic process uses the raw data collected through hydrographic survey into information usable by the end user.

Bathymetric scanning

Location Based Services

Location-based services (LBS) are the delivery of data and information services where the content of those services is tailored to the current or some projected location and context of a mobile user.
