Until recently, changes in ocean level were determined from tide gauge observations, currently from satellite altimetry. The main objective of this work is to analyse the available data from the satellite altimetry in order to determine the trend in the Baltic sea level changes. We used these data to investigate regional trend at selected eight tide gauge stations. In the first step sea level anomaly were extracted from the multi mission global product available at CMEMS and next analysed using Ferret and Hector software. Furthermore absolute mean sea level computed from tide gauge data and GNSS observations was taken from the SONEL web page. The results were compared and this comparison shows some differences in both method of the order of 1 mm/year and significant difference of the order 2.4 mm/year at station Helsinki.","PeriodicalId":145350,"journal":{"name":"2018 Baltic Geodetic Congress (BGC Geomatics)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132238158","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The investment process may commence when permission to carry out investment have been obtained from relevant authorities. Whereas environmentally valuable areas do not rule out investment, there are certain limitations to investing in such areas. Authors of the article present research carried out in the Pisz municipality. This work relies on data regarding planning permits in the municipality. Analytical tools have been used to determine relation between planning permits and the distance from the environmentally valuable areas, communication routes and residential areas. Performed research proves that environmentally valuable areas do not constitute a barrier to investment. On the contrary, it frequently happens that existence of such areas determines the investment attractiveness of a given area. The article also presents the opportunities of using the free GIS-QGIS software in the development planning analysis.","PeriodicalId":145350,"journal":{"name":"2018 Baltic Geodetic Congress (BGC Geomatics)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123635457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The two above tests, as it results from the above cited classification, are the basic tests of the samples used to determine the main conditions of strength of materials. To record strength tests, it was decided to use the Phantom Miro LC310 M camera.

The research was conducted in both lab and field conditions. Specially prepared samples were used for lab tests. Field tests were performed on a real building. Measurements were carried out using pulsed TLS scanner Leica ScanStation C10. Defects of flat brick surfaces were located using an algorithm based on Mean Sum Error. In this method a regression is harnessed to find an optimal reference surface. Specifying the reference surface was the basis for detecting cavities. Influence of a scan density, laser beam divergence and spot size on the effectiveness of scanning brick facades was discussed. Generally, the higher scan density, smaller the spot size and smaller laser beam divergence the higher the definition of the survey. The research results show that the surface delamination (cavities, cracks) of bricks facades can be effectively detected by a terrestrial laser scanning system.","PeriodicalId":145350,"journal":{"name":"2018 Baltic Geodetic Congress (BGC Geomatics)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128287851","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main purpose of the research is to create the concept to develop new models of data processing from sensors, their comprehensive fusion and consistent visualization. This will allow to present data in the form of 360 degrees spatial maps for coastal areas. This kind of map enables the visualization of spatial data both horizontally and vertically, creating one spherical image of the terrain surface.

These SSH were compared with the TG records in conjunction with an operational hydrodynamic model (HDM), both referring to a high-resolution national geoid. The Sentinel-3 data quality assessment yielded the root mean square error of 70 mm with respect to the TG+HDM derived SSH. The near-zero mean of discrepancies shows that there is no significant systematic bias between the land-bound geodetic infrastructure and Sentinel-3 SSH data. This accuracy is within the range aimed for modern marine geoid modelling (i.e. 5 cm).","PeriodicalId":145350,"journal":{"name":"2018 Baltic Geodetic Congress (BGC Geomatics)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122751440","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This has led the European Commission to establish strict daily and annual PM concentration limits. The monitoring of air quality in major cities is the responsibility of European Member States. The Tricity, a 414.81 km2 area in northern Poland, is monitored by a network of only 9 stations operated by the non-profit ARMAAG foundation. The stations provide hourly pollution and meteorological measurements in key areas of the Tricity, however the information regarding air quality in areas devoid of actual measurement stations must be obtained from other sources. The aim of the presented work is to relate the hourly PM10 concentrations in the Tricity area to other available data of various scale and resolution in order to provide a possibly accurate representation of air quality in the entire Tricity area.","PeriodicalId":145350,"journal":{"name":"2018 Baltic Geodetic Congress (BGC Geomatics)","volume":"417 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117316156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The idea is to compare the trajectories of a new ship and historical ships within a comparison area. The future behaviour of the new ship was estimated with the k-nearest neighbours. The performance of the method as well as the hyper parameters (nearest neighbours, k, and a weighting parameter α) of the proposed model were optimized using nested leave-one-out crossvalidation approach.
