ABSTRACT

This paper presents the detailed workflow of a large mobile mapping project held in 2014 for 3D High Precision Mapping purposes. The acquired data includes GNSS/Inertial data for Georeferencing purposes, 360 degree panoramic imagery, 4 high resolution still digital camera imagery and two high end laser scanning data. This presentation also examines the multi-faceted technological and organizational challenges associated with completing a project with high accuracy requirements in an urban centre with many challenges such as high-rise buildings, traffic congestion and heavy construction.

During the course of this project, Navmatica conducted a detailed geometric accuracy analysis focused on a number of parameters including:

  • GNSS/Inertial achievable accuracy in crowded urban centres, especially in the presence of high rise buildings, tunnels and bridges
  • Camera/IMU Boresight calibration accuracy and calibration stability
  • Laser/IMU Boresight Calibration accuracy and calibration stability
  • Accuracy of final 3D Point Cloud after Registration of multiple scenes
  • Overall system accuracy in different urban cases
  • Automated processing for feature extraction of features from laser and image sequences
  • Quality Control procedure and its effect on final mapping accuracy

ABSTRACT

A number of Projects have been recently completed by Navmatica in a number of countries in the Middle East where Geodetic Networks have been established using GNSS. This paper presents the detailed workflow of establishing geodetic Networks using GNSS in practice. Factors affecting GNSS data acquisition, data processing and Network Adjustment are highlighted in this presentation. Factors affecting the final geometric accuracy are addressed in some detail. This presentation also examines the multi-faceted technological and organizational challenges associated with completing a project with high accuracy requirements in rural or urban centres.
