Consumers and institutional kitchens, as well as traders, have shown increasing interest towards local food. This is particularly due to the transparency and traceability characteristic of a short supply chain and social aspects related to food origins. The trend has been increasingly common during the past decade in Europe and North America, and it is strongly evident in the case area of this study in Northern Ostrobothnia, Finland. In general, ease of access to food is highly important for consumers and crucial for institutional kitchens, in addition to quality aspects and price. However, regardless of proximity, poor accessibility is one of the key issues preventing the further growth of local food markets. Due to scale economics in food value chain, food transport is presently organised mainly by centralised, large-scale logistics companies directed via hubs serving millions of consumers. Accordingly, production volumes required to enter large-scale markets are often unattainable for disjointed small-scale local food producers. In this study, geographic information system (GIS)-based accessibility analyses are applied for analysing potential for integral networking of local food production and transport companies. Berry production was selected as a case study because it has a relatively strong role in Northern Ostrobothnia, while its logistics are notably underdeveloped. Spatial data of primary production volumes consists of register records of farm-specific cultivation areas and average yields in Northern Ostrobothnia and Finland. Accessibility computations are based on the digital model of the Finnish road network, Digiroad. Two surveys were also implemented to farmers and food processing companies to seek views on food processing, sales, logistics and procurements regarding local food. Data from the surveys was used in accessibility analysis, which enables exploration of opportunities for establishing ‘local food’ clusters integrating small producers into a more effective and competitive network. Information about favourable conditions for cooperative networks in the local food sector may help in establishing companies and their growth. Again, successful networking may increase scale economies in local production in transport, processing and marketing.
Geographic information systems (GIS) and their tools support the process of real estate trading. Of key importance is the ability to visualise information about real estate in the form of maps of average real estate transaction prices. The following study presents a methodology for mapping average real estate transaction prices using GIS. The map development process comprised three main stages. In the first stage, the input data was processed and statistically analysed. Official data came from the Register of Real Estate Prices and Values, and open data from the National Register of Boundaries. The second stage involved the visualization of the data in the form of maps of average apartment prices using the cartographic methods of choropleth maps and diagrams. The commercial tool ArcMap 10.3 and the free Quantum GIS software were used in the design of the maps of average real estate transaction prices, to check the options for using these types of programs. As a result, eight maps were designed presenting the average transaction prices for residential properties in the Warsaw district of Ursynów in 2015. The final stage was the analysis of the designed maps. The influence of the selection of the reference units on the visualization content, and the impact of combining cartographic presentation methods on the complexity of the presentation of real estate information, were also analysed.
The article presents the content of digital thematic maps: sozological and hydrographic as well as the basic principles of their preparation. It contains selected examples of applications of these maps in the research of natural environment and water management in the Upper Silesia region and its surroundings. This area is one of the most transformed regions due to human economic activity in Europe.
Over the last several years, Poland has experienced dynamic development of linear infrastructure, mainly regarding national roads. The changes are reflected in the condition of the market of land located in the vicinity of newly constructed roads. The location of a property in the vicinity of an express road junction offers more convenient access to the labour market or sales market. On the other hand, possible negative effects include increased noise and pollution, as well as spatial continuum disturbance.
The objective of the study is the analysis of the effect of national roads on the development and dynamics of changes in prices of land in their vicinity. The estimation of the dynamics of such changes permits the determination of the stage of implementation of investments involving the highest variations of property prices. The analysis was conducted based on the following criteria: class of national roads (motorway or main express road) and the size of the urban centre located on route. The study involved the application of the Geographic Information Systems technology ArcGIS ESRI, data from the register of property prices and values, and cadastre information included on websites iGeoMap and Geoportal.
Land consolidation projects have reached the state where there is sufficient sample of projects with lots of valuable information in the Slovak Republic (planimetric and hypsographic measurements, updated maps of soil-ecological units, concepts of local territorial systems of ecological stability, plans for the general principles of functional organization of the territory, etc.). However, their longer-term utilization is questionable, because there is no central data archiving of the projects. Documents remain on a CD somewhere in the documentation of land offices in most cases. In worse cases, documentation might have been lent and later irretrievably lost. This paper describes concept for a new system that would provide a coherent overview, especially for the graphical outputs of land consolidation projects. It is called System OKTOPUS, and with its help we can analyze, process and archive the data generated in land consolidation projects and/or in other documentation. Spatial data are included into the catalog of topics and the topics are divided into registries in the OKTOPUS System. The presented model area is the catchment area of Žitava river, on which we illustrate the OKTOPUS System, including examples of possible use cases. The final aim of the OKTOPUS System is publishing data on the web using platform(s) that allow users sharing/editing the geographic data.
The valuation of non–marketed goods and services of beaches in developing nations is rarely conducted; thus, lax management efforts at these resource–rich places often lead to degradation. In an attempt to resolve this issue the research used the travel cost valuation method and incorporated the use of geographic information system to estimate a never-before-done non-market valuation of the area visited by respondents at the beach of Patenga of Chittagong, Bangladesh. The uniqueness of the research stems from defining the area enjoyed by the survey respondents, via mapping, which helped assign the value generated to that particular part of Patenga and not the rest; this significantly decreased the underestimation problem of the travel cost methodology. The research used secondary sources and collected responses and geographical data from surveys conducted over a seven day period in March of 2018, from 277 respondents. A value of at least 14,331,044BDT/USD1.71million was estimated for 2018 for only 9% of Patenga. Furthermore, the Willingness to Pay approach was used to propose an entry fee of 15BDT/USD0.18 which would yield a revenue of more than 6,750,000BDT/USD79,882 around the year. The authors believe, these results will push the policy-makers and encourage stakeholder participation to better implement and monitor environmental management measures at Patenga.
