ABSTRACT: Due to the development of ICT technologies the so-called sharing economy has spread all over the world, gaining significant market share in certain sectors. One of the well-known and debated manifestations of sharing economy is Airbnb, which is an online platform for accommodation provision. Airbnb has wide-spreading effects on rental and real estate markets, thus it is important to analyse the uneven spatial effects of the phenomenon. This paper aims to map and analyse the intra-urban spatial pattern of Airbnb using three indicators: prices, distance from centre, and attractiveness of the area. The case study area is Budapest, Hungary. Collecting data from various sources we compiled 3-band raster maps to present the significance of the selected indicators. The maps reveal the hotspots of Airbnb within the city and the effects of distance and attractiveness on Airbnb prices.

Keywords: Airbnb, GIS, Peer-to-peer accommodation, Budapest, Sharing economy.

ABSTRACT: Ponds are regarded as small waterbodies with a depth of less than 6m and an area of less than 100 ha. In the Limousine region (France), they usually bar small incised valleys, giving them a complex morphology. This morphology may separate the pond in several basins, as for the pond of La Ramade (45°47’04.3”N; 2°25’30.7’’E), theoretically suitable for a spatial variation of temperature. The pond has been implemented with 4 moorings chains composed of automatic thermistors, measuring the temperature every hour from the surface to the bottom. A meteorological station has been deployed close to the pond, in order to gather very precise meteorological information, in addition to the map of fetch and bathymetry. The working hypothesis is that even small waterbodies present a spatial heterogeneity of water temperature, so that the classic measurements only at one point give approximate values. The aim is to get a 3D overview of the thermal dynamic of a small waterbody for the purpose of a better understanding of its temperature dynamic, with heat content’s approach. In polymictic waterbody, the temporal but as well spatial variations of the heat content are together numerous and varied. The first results bring us the autonomous function of the bays and sheltering places, while the open water has a predictable function. Some parameters such as the fetch, the sheltering by vegetation or the bathymetry plays a more or less important role in the particularity of each basin. The heat content’s methodology shall be improved by consideration of the spatial variation of the pond’s temperature.

Keywords: Heat content, Water temperature, Pond, Spatial variation, Water Framework Directive.

ABSTRACT: As contracts are fact-specific statements so are the cartographic representations attached to them. This article addresses such representations dating to early eighteenth century Baroque Malta. It focuses on a specific public deed which includes a sketch plan covering a large territory. This representation, which is countersigned by ‘periti’, has no scale bar but includes orientation and annotations with respect to the extent of the territory subject of the deed. Through these annotations which included landmarks and linear measurements, the boundaries of the property were reinterpreted. Whereas the current interpretation is 35% in excess of the superficial area stated in the deed, a re-interpretation led to a variation of less than 1%. This illustrates that historical figurative cartographic representations are accurate, fact-specific legal documents with minimal variations.

Keywords: Cartographic representation, Architecture, Baroque, Perit, Malta.
