Airborne surveying forms the core of PASCO's geospatial information business.
Since our founding in 1953, we have continued to inherit and pass on aircraft surveying technologies. We constantly introduce the latest equipment, and have consistently maintained a high level technical expertise.
- Aerial photogrammetric surveying (UCXp, UCX, ADS, RC)
- Photogrammetric surveying forms the basis for airborne surveying. From analogue photography (photography using film) to digital photography, it is indispensable to the production of maps.
- Aerial laser surveying (fixed and rotating wings)
- Airborne surveying is effective when there is a need to obtain highly precise information about the elevation of a wide expanse of area. We obtain airborne LiDAR point cloud data, which comprises elevation information, by conducting laser surveying from aircraft.
- Thermal sensor surveying (TABI)
- Airborne thermal sensor surveying involves obtaining the heat distribution on a wide expanse of ground surface, in order to study, among other things, the heat island effect that is a contributing factor for global warming. It is useful for research pertaining to disaster prevention and the environment, such as through gaining an understanding of surface temperature distribution of the areas near a volcano crater.
- Hyperspectral sensor surveying (AISA)
- By measuring the wavelength of visible and invisible light, hyperspectral sensor surveying plays a useful role in various types of studies. These include surveys on rice growth, forest type classification map (species of trees, density of crowns, etc.), water quality surveys (chlorophyll, turbidity, etc.), and surveys on coral reefs (corals, seaweed beds, etc.)
- Portable Aerialphotography and Locator System(PALS)
- PALS developed by PASCO is able to obtain information on the location of the subject while taking the photograph. In the event of a natural disaster, it is possible to get a grasp of the damage situation earlier using this system.
