14th CONFERENCE ON SCIENCE AND TECHNOLOGY INTRODUCTION TO “BKHCM” SOFTWARE FOR ADJUSTMENT, ACCURACY ASSESSMENT AND DESIGN SURVEYING NETWORKS Loc Dao Department of Geomatics Engineering Outlines  Objectives  Introduction to BKHCM  Adjustment  Survey network design  Assess stability of control points with iterative measurements over several periods  Comparison with other software packages  Conclusion 2 14th conference on science and technology 05/09/2021 Objectives  Having a software package for adjusting vertical and horizontal networks on the plan or Cartesian  Supplying a tool for analyzing and designing wide range of surveying networks  Assessing the stable benchmarks after having data measurements over several periods 3 14th conference on science and technology 05/09/2021 What is “BKHCM”?  Written by using Delphi programming language (developed from Pascal). The software is compiled into .exe file running on PC with OS window 95 or later OS.  BKHCM’s menus look like Microsoft Office 2007 (Ribbon style), it also offer many window forms to input data and display results. 4 14th Conference on science and technology 05/09/2021 BKHCM software Bình sai "BKHCM" Phân tích ổn định 5 14th Conference on science and technology Thiết kế lưới 05/09/2021 Constrained adjustment of level networks 6 14th Conference on science and technology 05/09/2021 Constrained adjustment of level networks 7 14th Conference on science and technology 05/09/2021 Loading a level diagram into software 8 14th Conference on science and technology 05/09/2021 Free adjustment of level nets 9 14th Conference on science and technology 05/09/2021 Report of level adjustment 10 14th Conference on science and technology 05/09/2021 Constrained adjustment of horizontal surveys: traverses and networks 11 14th Conference on science and technology 05/09/2021 Result of horizontal adjustment 12 14th Conference on science and technology 05/09/2021 Automatic displayed diagram networks with BKHCM 13 14th Conference on science and technology 05/09/2021 Result: free horizontal adjustment network 14 14th Conference on science and technology 05/09/2021 Misclosures/loop closures for traverses and networks 15 14th Conference on science and technology 05/09/2021 Adjustment of GPS networks 16 14th Conference on science and technology 05/09/2021 Checking loop closures and misclosures in GPS networks 17 14th Conference on science and technology 05/09/2021 Combining GPS and terrestrial observations 18 14th Conference on science and technology 05/09/2021 Combining GPS and terrestrial observations 19 14th Conference on science and technology 05/09/2021 Data input 20 14th Conference on science and technology 05/09/2021
