Interpretation of mutual positional errors of identical points in Digital Technical Map of Ostrava City and Digital Cadastral Map in cadastral district of Hošťálkovice

Abstract

This paper deals with the comparison of two map bases in the cadastral district of Hošťálkovice on the map sheet of Opava 0-9/44. The first one is the Digital Technical Map of Ostrava City (DTMOC) and the other is the Digital Cadastral Map (DCM). The determination of mutual positional errors is important when analysing the usability of the data taken from the DCM for completing and updating the DTMOC.
