Correlation testing of Müller’s map of Bohemia and the First Military Survey maps in the area of today’s Czechia

Popis výsledku v původním jazyce

The paper attempts to bring answer to a hypothesis assuming a relation of origin of maps of the First Military Survey, performed by the Habsburg Empire in the last third of the 18th century, with their predecessor – maps of Bohemia and other lands created by Johann Christoph Müller. Records in literature mention the geospatial origin of the military maps as miniatures of Müller’s maps but no clear evidence to this statement has been performed. Within the paper, a correlation analysis using seamless rasters of joined map sheets adjusted to their original sheet size has been used for both map works. The preliminary results show a significant closeness of the mentioned statement to the truth. Within the computations, the ratio of scale numbers of both works has been defined, allowing estimating the scale number of Müller’s map using the known value for the military mapping. Furthermore, deviations of rotation and position accuracy of both works have been examined. As an intermediate environment, the Křovák’s system to which the Müller’s maps had formerly been georeferenced was chosen. Using it, testing of normal probability distribution of errors of both map works has been performed allowing drawing conclusions about systematic or random character of the deviations. At last, visualizations showing differences between rendition of the maps’ deformation grid to an ideal state as well as further outputs have been presented. A relatively serious issue in the computations is constituted by large amount of control points (several thousand for both map works and whole Bohemia), which limited deployment of more robust solutions of spatial transformation computation.
