Among others, the groundwater is a very important source of drinking water and a significant element of the agricultural economy. Water budget (balance), a basic quantity of hydrology, is used to assess the amount of water in the ground needed for consumption. This is the reason why the water budget must also be calculated, even if the basic purpose is the groundwater level determination from GRACE data. Water budget computations are based on evapotranspiration and land surface hydrosphere state. The quantities required to calculate it can be obtained from land data assimilation systems, like American GLDAS (Global Land Assimilation System). In this paper, all the components of the water budget, like precipitation, surface run-off and evapotranspiration, are studied over the area of Poland. The resultant water budget is determined, interpreted and presented graphically.","PeriodicalId":145350,"journal":{"name":"2018 Baltic Geodetic Congress (BGC Geomatics)","volume":"57 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":"125685101","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}

We are interested how increasing reliability of the Hodges-Lehmann weighted estimate of the shift influences the distribution and the accuracy of the estimated point displacements. We examine a simulated levelling network and assume that the outliers may occur in both measurement epochs. We consider two variants of the Hodges-Lehmann weighted estimates and the classical non-robust approach, i.e., the least squares estimates. The results show that a new variant of the Hodges-Lehmann weighted estimates with \"strengthening\" some height differences (where it is possible) and applying the weighted mean results in better accuracy and smaller excess kurtosis in relation to the basic variant of the Hodges-Lehmann weighted estimates. The new estimate variant has superior reliability, so it may be advisable and helpful in some problems in deformation analysis.","PeriodicalId":145350,"journal":{"name":"2018 Baltic Geodetic Congress (BGC Geomatics)","volume":"55 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":"127582092","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}

It allows for relatively easy detection of archaeological sites that have their own field form, e.g.: barrows, fortresses, ancient fields. As a result of the scanning, the point cloud is obtained, often consisting of millions of points. Such large measurement datasets are very time-consuming and labor-intensive in processing. Therefore, works on optimization of those datasets are constantly being carried out [3]. In this study it was decided to test the Optimum Dataset (OptD) method. It allows to reduce the measurement dataset, what can improve DTM generation, 3D modeling of archaeological objects. The OptD method was used for the development of Terrestrial Laser Scanning measurements of barrows. The acquired point cloud has been reduced in several variants to show the degree of reduction.

Then, spatial clusters of the data were identified due to the fact that in some areas of the city the points occurred in large concentrations, which could have a significant impact on the spatial analysis of the described phenomena. As a result of clustering, a generalised distribution of data was obtained and presented on a map. Based on calculations, a comparative analysis was performed on data before and after the generalisation. The method employed was the kernel density estimation. A comparison of the data within the boundaries of different sub-districts made it possible to assess whether generalisation significantly affects the density distribution of the analysed phenomena.","PeriodicalId":145350,"journal":{"name":"2018 Baltic Geodetic Congress (BGC Geomatics)","volume":"989-994 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":"131789159","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}

Measurements were made using a CG-5 gravimeter manufactured by LaCoste & Romberg Scintrex Inc., and determinations of position used a Leica Viva GS15 receiver integrated with a network of HxGN SmartNet GNSS reference stations. The measuring methodology required gravimeter readings to be taken at an absolute measurement station in the Polish official gravimetric network and at new stations. The adopted profile method entailed making a two of measurements at all stations. The measurements relate to terrain with a relatively small height difference between the starting point and end point. It is standard in such cases to assume that gravitation varies linearly with height. This assumption is better satisfied when the gravimetric series is shorter and there is less height variation within it.","PeriodicalId":145350,"journal":{"name":"2018 Baltic Geodetic Congress (BGC Geomatics)","volume":"1 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":"124060852","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}
