Journal of Geospatial Surveying

Editor-In-Chief: Dr. Ranmalee Bandara  



The Journal of Geospatial Surveying (JGS) is a peer reviewed journal aiming to publish scientific research and technical developments in the field of Geoinformatics and Surveying. Its goal is to provide a forum for Sri Lankan and international scholars to publish high quality articles on current issues in the field. Papers dealing with innovations in theoretical, experimental and system design aspects are welcome.

  • The introduction of VLBI, SLR, and GPS system into the network.
  • The Minna datum should be defined very accurately with SLR (or GPS) technique.
  • Carry out a rigorous (least squares) adjustment on all existing stations.
  • To strengthen weak triangulation chains.
  • Use Control Superstructure for improving the Geodetic Network.

  • New index was developed to find the ocean harvested plastic using Sentinel 2 images.
  • The index was tested with ACOLITE and Sen2cor corrected Sentinel 2 images.
  • The 14% plastic bottles and 50% bags\fishing nets pixels were detected by the index.
  • The accurate detection depended on the pixel percentage and the coverage of plastic.
  • The Acolite and Sen2cor images are not suitable for detecting weak plastic signals.

  • Datum transformation parameters are determined by using least squares adjustment
  • Bursa-Wolf, Molodensky-Badekas and Veis are commonly used transformation models
  • Molodensky-Badekas and Veis Models are more suitable models for Sri Lanka

WHO WE ARE

The Faculty of Geomatics offers high quality geomatics related degrees and consists of a well qualified staff and latest technological resource. The faculty was established in 2004 as the successor of the Department of Surveying Sciences, which introduced the BSc in Surveying Sciences Degree Programme in 1997. Throughout the past decades it is being greatly developed both in infrastructure and human resources.
