Topographic and Airborne LiDAR

1. Topographic Survey

Topographic survey is activity to map an area or region. This survey mapped is a state of relief (height) of the earth’s surface, the state of the landscape such as rivers, streams, settlements. The tools used such as total station, water pass, roll mater.

The scope of work PT. PER for topographic survey are :

  • Map making persil
  • Topgraphic map
  • DED Map
  • Installation and Measurement of Bench Mark (BM)
  • Stake out/Re Survey of Drill Hole
  • Map for civil construction

2. Airborne LiDAR

LiDAR is Light Detecting and Ranging, is new method to earth mapping with regional scale. With LiDAR spasial data can be delivery more faster and eficient. LiDAR survey using air craft to bring the camera or equipment when acquistion data in the field.

LiDAR Airborne Delivery :

  • ¬†Orthophoto
  • Digital Elevation Model (DEM)
  • Digital Surfaca Model (DSM)
  • Topographic Map

PT. PER association with PT. Asi Pudjiastuti Geosurvey  to execute this survey
