Refinement of Cadastral Maps

The amended cadastral ordinance takes effect from 1.7. 2009. Until this date the only cadastral maps for which two lists of coordinates for detailed survey points were filed were digitalized cadastral maps in stable cadastre coordinate systems. The entry into force of the amended ordinance has introduced the obligation to file these lists in all forms of cadastral maps. We have one file with coordinates of image and a second one with coordinates of position. The accuracy of the detailed survey points is defined by a quality code. The quality code is indicated in only one of the lists: either that of the image coordinates or that of the positional coordinates. The type of quality code depends on the willingness of property owners to sign a substantiating declaration of consent regarding the demarcation of a boundary line or the refinement of a boundary line. An integral part of the substantiating declaration is a survey sketch. The paper deals with survey sketch variants with regard to the amended ordinance.
