Initial Use of Statistical Analysis for Estimation of Horizontal Accuracy of Large-Scale Digital Maps

Abstract: The paper presents estimation of horizontal accuracy of maps using of initial statistical analysis. Investigations have been performed for four large-scale digital maps made with different methods of producing digital map data: new total station survey (object A), re-calculation of previous direct measurements (orthogonal and polar surveys) (object B), manual vectorisation of a raster orthophotomap image (object C) and graphical-and-digital processing of analogue maps (object D). Analysis has been performed fo… Show more

Distributions of investigated sets of true errors are, in general, not compliant with MND Romanowski distributions (DOSKOCZ 2005), what results from their skewness as it is known from literaturè utilisation of modulated normal distributions is not fully consistent in conditions of existing asymmetry' (WIŚNIEWSKI 1986).…”

“…Analysed the sets ε X , ε Y are slender (leptokurtic) in majority of cases, with respect to Gaussian distribution (except of ε X and ε Y sets of the object A, the ε Y set of the object D-5 and the ε Y set of the object B-7); prevailing discrepancies of their distribution occur in central class intervals of the distributive series. Detailed results of investigations of compliance between distributions of sets of true errors with theoretical distributions are presented in the paper (DOSKOCZ 2005).…”

“…The standard statistical analysis of these four data sets containing errors of the methods did not bring the expected results [28]. The main reason was that the considered data sets contain outliers and are not normally distributed, which is quite typical while working with real data sets, such as geodetic surveys.…”

“…We współczesnych bazach danych map wielkoskalowych w Polsce zgromadzone są dane pozyskane różnymi technologiami na przestrzeni kilkudziesięciu lat, a rozkłady błędów stwierdzonych na punktach kontrolnych nie wykazują zgodności z rozkładem normalnym i z innymi teoretycznymi modelami błędów [15,17]. W związku z tym, w badaniach dokładności opracowania sytuacyjnego wielkoskalowych map cyfrowych -obok klasycznej oceny dokład-ności w nawiązaniu do obowiązującego standardu dokładności opracowania sytuacyjnego (0.3 mm w skali mapy) oraz przeprowadzenia analiz zgromadzonych zbiorów błędów współrzędnych kontrolnie pomierzonych szczegółów sytuacyjnych I grupy dokładnościowej -zaproponowano metodykę badawczą [19].…”
