The cadastral data, including land parcels, are the basic reference data for presenting various objects collected in spatial databases. Easy access to up-to-date records is a very important matter for the individuals and institutions using spatial data infrastructure. The primary objective of the study was to check the current accessibility of cadastral data as well as to verify how current and complete they are. The author started researching this topic in 2007, i.e. from the moment the Team for National Spatial Data Infrastructure developed documentation concerning the standard of publishing cadastral data with the use of the WMS. Since ten years, the author was monitoring the status of cadastral data publishing in various districts as well as participated in data publishing in many districts. In 2017, when only half of the districts published WMS services from cadastral data, the questions arise: why is it so and how to change this unfavourable status? As a result of the tests performed, it was found that the status of publishing cadastral data is still far from perfect. The quality of the offered web services varies and, unfortunately, many services offer poor performance; moreover, there are plenty services that do not operate at all.
The fundamental importance of cartographic signs in traditional maps is unquestionable, although in the case of multimedia maps their key function is not so obvious. Our aim was to search the problem of cartographic signs as a core of multimedia maps prepared by non-cartographer in on-line Map Services. First, pre-established rules for multimedia map designers were prepared emphasizing the key role of the cartographic signs and habits of Web-users. The comparison of projects completed by a group of designers led us to the general conclusion that a cartographic sign should determine the design of a multimedia map in on-line Map Services. Despite the selection of five different map topics, one may list the general characteristics of the maps with a cartographic sign in the core.
