With growing importance of the global economy, one of the basic natural resources − intensity of land use − is also increasing, which often is the cause of land degradation processes. The causes and manifestations of brownfields are diverse, and their elimination is the first prerequisite for the sustainable use of land resources and development of each region. Improvement, maximal and efficient engagement in economic activity of brownfields is one of the key challenges for sustainable resource use that makes significant contribution to regional development. The reuse of brownfields has significant impact on sustainable development as it meets all three of its objectives: improving the economy, improving social cohesion and the environment. The aim of the article is on the basis of special literature examples to examine issues of sustainable development, evaluation and restoration of brownfields, transformation of brownfields into recreational areas, as well as further use of brownfields in cities and rural areas.

In order to evaluate the accuracy of the local geodetic network of Jurmala City, in research, comparison of fortyseven selected polygonometry network point coordinates with the obtained data was made by performing measurements by real time cinematic (RTK) method in LatPos base station system. Points were chosen so in order to cover evenly the entire territory of the city. At present, gradual renewal and improvement of the local geodetic network takes place in Jurmala. In Jurmala City, obtaining of data by GNNS data receivers is encumbered by large density of trees. Therefore the local geodetic network in city has very important role in order to ensure performance of geodetic measurements of high quality in the territory of the city. Aim of the research is to evaluate the accuracy of the local geodetic network of Jurmala City. The following tasks have been set for achieving the aim: research of the given problem, visit of the local geodetic network points, performing control measurements, data processing and analysis.
