Abstract
The problem of capturing data concerning parcel boundaries, which determine the spatial range of proprietorship is very important and has been up-to-date for many years. There is no doubt, that process of collecting such an important information should be performed in a way that ensures the highest possible accuracy and reliability. However, as it turns out, these two notions do not always go hand in hand. In accordance with being in force law, it is permitted to reveal data concerning parcel boundaries obtained by direct, photogrammetric and cartometric methods in cadastre. The accuracy and reliability of these data are of course different. That is confirmed by materials derived from surveying documentation centres. On the base of the materials, analysis concerning errors of parcel corners location in selected cadastral units has been performed. The problem of the reliability of the revealed data collected by the above-mentioned methods has been analysed too. Finally, it was found that despite the significant technological progress in the fields related to surveying and cartography, data concerning parcel boundaries revealed in cadastre, at the present time cannot be recognised as equally accurate. It is also very important to properly distinguish accuracy and reliability terms. We should be aware, that the high accuracy of data does not always indicate their high reliability.
