The characteristic feature of technical infrastructure is its linear nature, i.e. its course through numerous real estates, resulting in limitations imposed on such properties. The limitations differ depending on the stage of the investment process. Such stages include the formal legal stage (designing and collecting appropriate permits and decisions), the investment implementation stage, and the stage of exploitation of transmission devices. Within the first stage, a limitation concerning land development may occur (location of investments in planning documents); limitations of the use of land properties always occur in this case (acquisition of a legal title to the land property disposal for building purposes). At the stage of construction, i.e. the investment implementation, limitations related to the deterioration of the use of the land property may appear. The third stage may involve limitations connected with the presence of transmission devices in the space of the land property, i.e. limitations which result from the actual use of the land property by the transmission company. The objective of this paper is to identify limitations imposed on land properties resulting from the construction and exploitation of transmission infrastructure in Poland.

The BSCD2000 will be a geodetic height system that uses an equipotential surface (geoid) as zero reference level for height/depth determination. For this an international FAMOS (Finalising Surveys for the Baltic Motorways of the Sea) project has been initiated to improve the gravimetric quasigeoid model that will be needed for the realisation of BSCD2000 over the Baltic Sea. The goal is to improve the accuracy of GNSS-based bathymetric measurements and navigation by computing a new geoid model with 5 cm accuracy over the Baltic Sea. Even though the entire Baltic Sea is included in previous geoid modelling projects such as the NKG2015 and EGG07, the accuracy of contemporary geoid models over marine areas is unknown, presumably being offshore around 15-20 cm. An important part of the FAMOS efforts is conducting new marine gravity observations on board hydrographic surveying ships or as dedicated gravity survey campaigns. These new data are essential to the project as the existing gravimetric data in the Baltic Sea may be not dense and accurate enough for the purpose of 5 cm geoid modelling. However, it is important to evaluate geoid modelling outcome by independent data. On land, geoid models are customarily assessed by using precise leveling and Global Navigation Satellite System points, whereas in offshore such control points cannot be established. Instead, marine geoid models can be assessed by continuous GNSS measurements on board ships. Accordingly, this study presents results of the ship-borne marine gravity and GNSS campaign held by the Estonian Maritime Administration survey vessel Jakob Prei in West-Estonian archipelago in June/July 2016. Emphasis of the study is on principles of using the GNSS-profiles for validation of existing geoid models, post-processing of GNSS raw data, low-pass filtering of the GNSS results. The GNSS-derived heights are corrected to account for the systematic effects induced by ship dynamics and other static or dynamic impacts from tides, atmospheric pressure, or wind stress. It is concluded that the marine GNSS datasets have potential in providing complementary constraints in problematic geoid modelling areas.

Buvo suprojektuotas antrosios klasės vertikalusis tinklas iš 165 linijų, kurių bendras ilgis apie 4850 km. Vienok iki 2013 m. buvo išmatuota tik 16 antrosios klasės vertikaliojo tinklo linijų (814 km), jungusių 551 punktą. 2013-2016 metais pagal naują projektą įrengta 2273 km antrosios klasės vertikaliojo tinklo linijų, užpildančių vertikaliojo pirmosios klasės tinklo penkių poligonų vidų ir teritorijos dalį iki valstybės sienos. Antrosios klasės vertikaliajame tinkle yra 2099 gruntiniais ir sieniniais ženklais įtvirtinti geodeziniai punktai. Antrosios klasės niveliacijai naudoti skaitmeniniai nivelyrai Trimble DiNi12 ir kodinės matuoklės Nedo LD13. Gruntiniais ženklais įtvirtinti punktai koordinuoti GPS imtuvais Trimble 5700. Sunkio pagreičio nustatymui punktuose atlikti matavimai gravimetrais Scintrex CG-5. Sudarant vertikalųjį tinklą laikytasi reikalavimo, kad išmatuotų aukščių skirtumų vidutinės kvadratinės paklaidos būtų ne didesnės nei 0,7 mm/km. Straipsnyje pateikiami antrosios klasės vertikaliojo tinklo linijų duomenys, aprašyta matavimų metodika, pateikti normalinių aukščių skirtumų išlyginimo ir tikslumo įvertinimo rezultatai.

Experience of Western countries shows that an economical environment and it‘s potential performs as a catalyst processes of BF regeneration to areas of new a funtion. Basically, the potential of economical environmental is a reflection of local and foreign investments. Desicion making in urbanism and in economy examples of recent years shows that in order to implement right desicions the role of Big data is not enough. For this Smart data must be used. Inadequate evaluation causes a wide range of inconviences for citizens in long time perspecitve. Due to similarities in scale, demography, social life and availability of data resources the authors selected Liverpool and Vilnius cities as a targets of the research. These cities are featured by differences in functional zones and historical context. The aim of the research is to determine a potential of conversion of BF by identifying the root differences of urban environment, social life and economy in both cities. The results allow to determine the essential guidelines of territory amd spatial planning for such scale cities as Vilnius or Liverpool. Geostatistical analyzes includes a complex evaluation of indicators of economy, social life and urban environment. Packages of open and developed geostatisical data was used in this research. Geostatistical analysis was implemented by using geographical information system (GIS). By implementing this way of research the authors prepared themical data maps that corresponds to the result of the research and revealed the significance of spatial relationship between BF and social, economical and urban environment. Results of the research will ease complex sustainability development that will address to economical growth.
