Challenges of Current National Reference Frame (NRF) and Map Sheet Layout in Nepal Cadastral Mapping

Systematic Cadastral mapping in Nepal used to be carried out using local coordinates. Later National Reference Frame (NRF) and a map sheet layout is being improve the situation. Current trend of use GNSS establishing control points demands set transformation parameters. The coordinates NRF which are obtained by transforming results, does not give expected accuracy for large scale mapping. In addition, line with guidelines due complications at margins projection zones. conclusion current appropriate further – improvements reference frame as well system.
