"Visualizing the Quality of Vector Features - A Proposal for Cadastral Maps";
Talk: ISPRS Geospatial Week 2017, Wuhan, China; 2017-09-18 - 2017-09-22; in: "ISPRS Geospatial Week 2017", W. Shi et al. (ed.); ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, IV-2/W4 (2017), ISSN: 2194-9042; 537 - 542.

A well-known problem of geographical information is the communication of the quality level. It can be either done verbally / numerically or it can be done graphically. The graphical form is especially useful if the quality has a spatial variation because the spatial distribution is visualized as well. The problem of spatial variation of quality is an issue for cadastral maps. Non-experts cannot determine the quality at a specific location. Therefore a visual representation was tested for the Austrian cadastre. A map sheet was redesigned to give some indication of cadastral quality and presented to both experts and non-experts. The paper presents the result of the interviews.
