The map is the key element in any navigation system. The dynamic growth of indoor navigation systems requires improvements in quality not only of positioning systems but also of maps of building interiors. Most emergent solutions in this field do not use cartographic knowledge. Cartographic methodology for representing building interiors is still in its initial stages of development. Its proper use may, however, be of great importance to the effectiveness of indoor navigation. The author presents important features that indoor mobile maps should possess, for both the data model and the presentation method to be used. In this context, the question of the contemporary definition of a map is also discussed.
The article presents the results of the aircraft Cessna 172 positioning based on navigation solutions in the GPS and EGNOS (SBAS) tracking mode. The article makes a comparison of coordinate readings of the Cessna 172 in the ellipsoidal BLh frame. The verification of the coordinates of the aircraft Cessna 172 was used to assess the reliability of the GNSS satellite technique in aviation. In a research test, the navigation data were recorded by the onboard receiver Thales Mobile Mapper during an air test performed over the military aerodrome EPDE in Dęblin. Judging by the conducted investigations, it is possible to conclude that the difference in BLh coordinates of the aircraft Cessna 172 on the basis of the GPS solution and EGNOS (SBAS) solution equals, respectively: from −0.5 m to +3 m for component B; and from −2 m to +6 m for component L; from approximately −11 m to over +1 m for component h. In addition, the paper defines factors of dilution of precision PDOP, based on the GPS and EGNOS (SBAS) solutions. The average value of the PDOP coefficient for a solution in the tracking GPS mode was 2.7, whereas in the EGNOS (SBAS) tracking mode, it was equal to 2.8.

mobile devices on mobile search behavior. Church and Oliver (2011) suggested that limitations in screen size and the type of interactions and input that mobile devices can support play an important role in shaping the way that mobile users use mobile search engines. Kamvar and Baluja (2006) found out that Google’s PDA logs related to searches originating on PDAlike devices with sophisticated input capabilities. Park and Ohm (2014) introduced an integrated research model to examine user acceptance of mobilemap services in mobile devices. Studies of mobile devices

According to the report since 2012 the use of Internet among young people is higher than the use of computer obviating the need for the development of mobile applications to encourage the involvement of this group in local issues. One of the early studies investigating the involvement of younger citizens from Finland and Sweden in spatial planning mediated by PPGIS have shown the potential but also possible constraints and challenges in use of mobilemaps among younger citizens, especially children ( Broberg et al. 2013 , Nordin
