Refinement of Cadastral Maps

The amended cadastral ordinance takes effect from 1.7. 2009. Until this date the only cadastral maps for which two listsof coordinates for detailed survey points were filed were digitalized cadastral maps in stable cadastre coordinate systems. The entry intoforce of the amended ordinance has introduced the obligation to file these lists in all forms of cadastral maps. We have one file withcoordinates of image and a second one with coordinates of position. The accuracy of the detailed survey points is defined by a qualitycode. 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 regardingthe demarcation of a boundary line or the refinement of a boundary line. An integral part of the substantiating declaration is a surveysketch. The paper deals with survey sketch variants with regard to the amended ordinance.
