Land as a production factor occupies a special position in the economic activities of the urban population. Land resources in big cities are not only territorial basis for placing industrial and production structures, but also a space for urban life in general. However, to assess the effectiveness of urban land use, primarily the ecological and economic potential of the use of the urban land resources should be determined aimed at sustainable development of urban agglomerations (Volodchenkov, 2010). The rapid pace of development of large cities in the world and an increase of their impact on the environment and society is accompanied by the set of economic, ecological and social problems which significantly influence the development of settlements in general (Stolʹberh, 2000; Onyshchuk, 2001). However, the process of urbanization as a result of rapid scientific and technological revolution requires large areas for deployment of large scale production facilities and urban settlements in the conditions of natural resource management (Kontorovich, Rivkin, 1986).

Many studies have unveiled the importance of variation in residential property values overtime, but failed to cover different types of residential property value and location. The aim of this research is therefore to model residential property rental value in Bida from 2015 to 2020 with the aid of Geographic Information System (GIS). The study focused on the rental values of the residential property and rental value variation across space. Data collected for this paper includes residential rental values and geographic coordinates from 196 residential properties in the study area, comprising 101 one-bedroom, 80 two-bedroom and 15 three-bedroom apartments. Inverse Distance Weighted (IDW) interpolation tool of ArcGIS was employed in analysing the data. It was found out that the core areas of the town commands lower rental values while the southern part of the town commands higher rental values. It was also found out that one bedroom apartment is the most dominant residential rental property followed by the two bedroom apartments and three bedroom apartments respectively. Geospatial database was produced for each model in a bid to ascertain the level of changes with time. The benefits associated with the application of GIS technology were established by this research and recommends its application to other property values modelling.

The priority objective of the residential urban areas development – to improve the quality of life, sustainable development principles in order to form compact urban areas and polycentric functionally and socially integrated urban and suburban structure with the help of efforts of general public institutions as well as natural and legal persons. A living area today must comply with the needs of population from various social layers, so, when planning residential areas, it is necessary to assess the varied potential of the population needs and the quality of life expression. Therefore the article seeks to find out attitudes to residents’ environment, development of social services network, infrastructure condition, functional and planned structure of the area. For the implementation of the objective, the programme in the research sites has been prepared. This programme allows multifaceted examination of existing residential areas, the assessment of their physical condition, public opinion, public needs, comments and suggestions of professionals. After analysing the results of the research and drafting conceptual principles, it can be stated that the future of Lithuanian residential districts and cities depends on the territorial spatial planning system, which is affected by the free market and democratic society. Territorial spatial planning of residential microdistricts or blocks is the key to building sustainable and attractive cities.

This research study explores urban planning for transport sustainability in two cities Kaunas (Lithuania) and Jelgava (Latvia). As part of the analyses, a transport sustainability was compared in relation to three main aspects – economy, environment and society. The aim of this research is to review the existing transport system in two cities – Kaunas and Jelgava, and to evaluate their sustainability in environmental, social and economic dimensions. The study is based on the information about configuration and location of the existing transport system in two cities – Kaunas and Jelgava. It is important to submit proposals to decision making bodies in order to improve sustainability of transport.

Accessibility is a popular concept in many research areas, including spatial planning, where it denotes the possibility of reaching a specific location. Accessibility is not a characteristic feature of a single location: it is always measured between at least two locations (places), and it is strictly determined by the mode of transport. Subject to the evaluated parameter, accessibility falls into different categories, including physical accessibility which is defined by distance (meters, kilometers), temporal accessibility which is expressed in minutes and hours, and economic accessibility which is denoted by cost. In highly urbanized areas and their rural outskirts, spatial policies need to be coordinated to guarantee the effective distribution of functions and services. The optimization of accessibility should be the key goal of spatial policies adopted at both local and metropolitan level. The aim of this study was to analyze the applicability of public data sources and GIS tools for analyzing and improving spatial accessibility. A wide range of tools and data supports detailed evaluations of the spatial coverage and effectiveness of services (public and commercial), multi-objective optimization of planned locations and determination of the optimal service areas (with the use of gravitation and potential methods). Spatial planning is a process of selecting the optimal and rational functions for the existing space. A very wide variety of analytical tools can be deployed to acquire and process public data and research data. The results of multi-objective analyses can be support the planning proces.

The article presents the comparative analysis of the Kaunas city anthropogenic landscape change during the period between 2006 and 2014. For this analysis the land fund statistics of the Republic of Lithuania were used. The components of anthropogenic landscape change are graphically shown in the figures. During the analysis the Kaunas city statistics were compared with the data of Kaunas County and the Republic of Lithuania. Comparative, analytical as well as statistical and logical analysis methods were used for the investigation. The object of the investigation is anthropogenic components of Kaunas city. The aim of the investigation is to carry out the analysis of the change of Kaunas city anthropogenic components in the period of 2006-2014. The work analyses the change of urban landscape components, the reasons of the established change. The built up territories comprise the majority of anthropogenic landscape of Kaunas city i.e. 90.05 per cent, while the damaged territories make up 0.06 per cent and Kaunas city roads constitute 9.89 per cent of the analysed landscape. It was established that during the analysed period the built-up territories of Kaunas city increased by 312.78 ha i.e. 3.53 per cent. Within 9 years the road area increased by 14.04 ha or 1.44 per cent, while the damaged areas increased by 1.89 ha. Having analysed the statistical data of Kaunas city anthropogenic landscape areas it was estimated that within the period of 2006 -2014 the area of these territories increased by 328.71 ha or 3.34 per cent. e area of these territories increased by 328.71 ha or 3.34 per cent.

Local geodetic network is very important in harmonic development of city territory. On the base of the local geodetic network, cadastral and topographic surveying works, engineering geodetic works and executive measurements of newly built buildings and engineering networks are carried out. In the territory of Riga, the local geodetic network was started to create in 1880, and in the course of time, as the city expanded, necessity to have wider reference network emerged. In 2005, in the territory of Latvia, network of continuously working base stations LatPos was launched, which ensured completely new trends in execution of measurements and accuracy reached. One year later, base station network EUPOS-RIGA was launched in the territory of Riga. It can be regarded as consistent part of Riga local geodetic network. The purpose of the research was to state, what are differences between historically used coordinates of points of the local geodetic network, and coordinates that are determined by use of real time corrections of LatPos and EUPOS-RIGA base station network. Measurements were made in the territory of Riga in period from December 2016 until April 2017. In the framework of the research, 61 point of the local geodetic network was inspected and in 38 cases GNSS observations in RTK mode were completed. In the research, catalogues of coordinates of polygonometry points of sixties and eighties were used in order to compare what differences of coordinates existed historically. The main conclusion drawn during the research – historical points of the local geodetic network shall not be used for surveying works of any kind before improvement of them and before they comply with requirements of normative acts.

The study aimed at examining the spatial pattern of residential densification in housing submarkets of Bida, an ancient traditional town in Nigeria. The study adopted the 2015 standard residential density of Niger State Urban Development Board to determine the level of residential density and occupancy rates of the various submarkets of the town. The study also adopted primary method of data collection through the use of satellite images, handheld GPS and georeferencing of demarcated areas and the buildings, using point features and vector approach in ArcGIS environment to achieve the area coverage, number of buildings and buildings per hectare (ha) in the housing submarkets. The finding of the study reveals that in 2008 Town housing submarket has the highest area coverage, followed by the Project Quarters and then GRA, but in terms of residential density, four housing submarkets of Town, Rahmatu Dangana, Gbazhi and Wadata have high densities above the other seven submarkets. The study further reveals that in the year 2013, additional eight housing submarkets have high residential densities, GRA medium density while Eyagi and Prject Quarters had low densities respectively. It was therefore recommended that there is the need for rational densification (planned densification) for urban development in order to check the increasing unplanned residential density that reduces the green and open spaces in urban environment.

The issue of brownfields and their analysis in Slovakia have not been given such emphasis over the last decade as in the neighbouring EU countries, such as in Austria or in the Czech Republic. The situation is completely different in Bratislava and also in the rest of Slovakia and the development of this type of area is almost unrealized. A frequent argument is problematic ownership relationships to the unused, degraded land. However, the real problem is the higher financial costs associated with brownfields regeneration. Despite this fact, brownfields can be considered as an area with relatively large development potential within the urbanized area and one form of hidden reserves of both, local and national economy. Among the indisputable benefits of using brownfields, we can include reduction of the extensive land use of agricultural land for rural area. In the long run, Bratislava is preparing a search study of neglected and unused land within the capital. It is due to be completed in the course of 2018, and will be an important basis for a new territorial plan and the development of Bratislava. In the following article, we analyse brownfield land in Bratislava. The already realized brownfield projects are also mentioned, while we are trying to point out their main advantages and disadvantages.
