AB  - Processing of raw point cloud data obtained as a result of terrestrial laser scanning (TLS) sometimes involves georeferencing, i.e. transformation of point cloud data to an external coordinate system. This paper focuses on defining the error model of point positions obtained through a "station-orientation" procedure of direct georeferencing. The original error model presented by the authors relevant in this field is partly altered. All modifications are explained in detail within the paper and the reported model is statistically verified based on the carefully conducted experiment using Leica ScanStation P20 scanner. The obtained values of the uncertainty measures of direct georeferencing Which are of a few millimetre magnitude prove that this procedure can be efficiently used for planning and carrying out even more demanding surveying tasks, including those during monitoring and maintenance of constructed facilities. Additionally, traversing capabilities of terrestrial laser scanners tightly connected with direct georeferencing should contribute to mass introduction of laser scanning into the construction industry thanks to its similarities to the highly automated procedures of polar surveying and traversing which are traditionally employed among surveyors.

TLS data georeferencing - error sources and effects

AB  - Depending  on  the  requirements  of  a  certain  engineering  task,  point  coordinates  obtained through terrestrial laser scanning (TLS) can be either in a scanner coordinate system (CS) or in  the  coordinate  system  of  a  geodetic  control  network.  When  point  coordinates  in  some external CS are needed  point cloud georeferencing must be done, i.e. point coordinates have to be transformed from the scanner CS into the desired CS.Different  procedures  can  be  followed  during  the  transformation  process  of  point  coordinates from  one  CS  to  the  other  and  consequently  it  can  be  distinguished  between  several  types  of georeferencing. The principal classification is into direct and indirect georeferencing  and the main  difference  between  the  two  is  that  direct  georeferencing  can  (and  usually  does)  give point coordinates in the CS of a geodetic control network instantly in the field, while indirect georeferencing  inevitably  needs  some  work  to  be  done  in  the  office  in  order  to  obtain  these coordinates. Indirect georeferencing is necessarily done in some software and it distinguishes between  the  process  itself  being  completed  in  either  one  or  two  steps.  On  the  other  hand, direct georeferencing does not involve transformation into some intermediate CS whichis the case  with the two-step  indirect  georeferencing.  Direct  georeferencing  essentially  mimics  the procedure of orienting a total station with respect to a geodetic control network which can be achieved either through backsighting (the “station-orientation” procedure) or resection.This paper briefly presents different georeferencing procedures and related main error sources that  cause  errors  in  transformed  point  coordinates.  Additionally,  the  covariance  model  for direct  georeferencing  following  the  “station-orientation”  procedure  is  verified  through statistical  analysis  of  the  data  collected  in  the  experiment  performed  in  the  field.  True  point position  errors  calculated  as differences  between  point  coordinates  obtained  from  the  least squares  adjustment  of  the  geodetic  control  network  and  those  from  direct  georeferencing  of the  TLS  data  are  compared  with  theoretical  errors,  i.e.  model-derived  standard  deviations  of point positions. It is shown that these two setsof errors or, more precisely, the variance of the true errors and the pooled model-derived variance of the control point positions do not feature a significant difference at the confidence level of 99%. This makes us optimistic in terms of possibility of using the reported model for predicting trueerrors of point positions by model-derived  standard  deviations  obtained  as  a  result  of  direct  georeferencing  of  TLS  data following the “station-orientation” procedure.

AB  - Geodetic network design for numerous practical applications (surveying, staking out of characteristic points of an object in construction, control of geometry of a built-up object, monitoring, etc) represents a problem which requires implementation of well-known optimization methods. Optimization aim is establishing as much accurate and reliable geodetic network as possible with as less costs as possible. Geodetic network optimization is classified into different orders but in this paper only the second order design which deals with the determination of the weights of network measurements is presented. Within the second order design it is necessary to form a criterion matrix which substitutes real covariance matrix and to define observation scheme in network. The criterion matrix is formed by using one of the correlation functions whose arguments are distances between geodetic network points. This paper presents comparative analysis of the results of the second order design of trilateration geodetic network. These results were obtained by using TK-structured criterion matrices formed by using Gaussian and Baarda’s correlation functions of point coordinates. As it was expected, Gaussian correlation function is the one that proved as a better choice because it generally adapts better to the geodetic network requirements than Baarda’s correlation function: the results obtained by using Gaussian correlation function tolerate less accurate distance measurements.
AB  - Projektovanje geodetske mreže za razne potrebe u praksi (premer, obeležavanje karakterističnih tačaka nekog objekta u izgradnji, kontrola geometrije izgrađenog objekta, monitoring, itd.) predstavlja problem koji zahteva primenu poznatih metoda optimizacije. Cilj optimizacije je uspostavljanje geodetske mreže sa što većom pouzdanošću, tačnošću i uz što manje troškove. Optimizacija projektovanja geodetskih mreža klasifikuje se u različite redove ali je u okviru rada prikazana samo optimizacija drugog reda koja podrazumeva određivanje optimalnih težina planiranih merenja u geodetskoj mreži. U okviru optimizacije drugog reda neophodno je formirati kriterijum matricu koja zamenjuje realnu kovarijacionu matricu i definisati plan opažanja u mreži.

abstract = "Geodetic network design for numerous practical applications (surveying, staking out of characteristic points of an object in construction, control of geometry of a built-up object, monitoring, etc) represents a problem which requires implementation of well-known optimization methods. Optimization aim is establishing as much accurate and reliable geodetic network as possible with as less costs as possible. Geodetic network optimization is classified into different orders but in this paper only the second order design which deals with the determination of the weights of network measurements is presented. Within the second order design it is necessary to form a criterion matrix which substitutes real covariance matrix and to define observation scheme in network. The criterion matrix is formed by using one of the correlation functions whose arguments are distances between geodetic network points. This paper presents comparative analysis of the results of the second order design of trilateration geodetic network. These results were obtained by using TK-structured criterion matrices formed by using Gaussian and Baarda’s correlation functions of point coordinates. As it was expected, Gaussian correlation function is the one that proved as a better choice because it generally adapts better to the geodetic network requirements than Baarda’s correlation function: the results obtained by using Gaussian correlation function tolerate less accurate distance measurements., Projektovanje geodetske mreže za razne potrebe u praksi (premer, obeležavanje karakterističnih tačaka nekog objekta u izgradnji, kontrola geometrije izgrađenog objekta, monitoring, itd.) predstavlja problem koji zahteva primenu poznatih metoda optimizacije.
