Nine test lab comparative test indexes of asphalt and asphalt mixtures are analyzed by consistent statistic analysis method of ASTM E691 and Robust statistical analysis method, analysis results indicate that two methods are basically in consistent with each other, but dubious analysis index is added in Robust statistical method, and reliability is possibly enhanced on data analysis. Combined with advantages and disadvantages of two methods, the paper suggests that two statistical method can associated with each other in statistical data analysis.
The article deals with the possibility of georeferencing old multi-sheet map works. Various approaches to problem solving and a workable method for using the least squares method with the conditions of the adjacency of map sheets are discussed. To increase reliability, the IRLS robust statistical method is used, which uses iterative weighting of individual measurements based on Huber’s M-estimate. The method is applied to the First Military Mapping of the Habsburg monarchy as a typical representative of old topographic maps, which are not easy to georeference due to unknown parameters of the used cartographic projection. A georeferenced layer of the above mentioned mapping is available on the Mapire.eu portal as well. A basic analysis of the comparison of georeferencing results using our method and the mentioned portal is performed.
