In 1934, Paul Otlet, a Belgian entrepreneur, designed a proto-Internet which he called a r?seau mondial-- literally, "worldwide web." Today, Otlet and his vision have been all but forgotten, thanks ...to a series of historical misfortunes -- not least of which involved the Nazis marching into Brussels and destroying most of his life's work -- but Alex Wright brings Otlet's extraordinary story back into the light in this fascinating look at the dream of universal knowledge.
This paper focuses on issues related to the calculation of a high-precision fitted geoid model on Estonian territory. Model Est-Geoid2003 have been used in Estonia several years in geodesy and other ...applications. New data from precise levelling, new global models and terrestrial gravity data give plenty of possibilities for updates and accuracy evaluation.
The model is based on a gravimetric geoid. From the gravimetric data gathered, a gravimetric geoid for Estonia was calculated as an approximately 3-km net using the FFT method. After including the new gravimetric data gathered, the gravimetric geoid no longer had any significant tilt relative to the height anomalies derived from GPS-levelling points. The standard deviation between the points was 2.7 cm. The surface of the calculated gravimetric geoid was fitted by high-precision GPS-levelling points. As a result, a height transformation model was determined to reflect the differences between the normal heights of BK77 and the ellipsoidal heights of EUREF-EST97 on Estonian territory. The model was originally called Est-Geoid2003 and is part of the official national geodetic system in Estonia. The model is updated and evaluated here using precise GPS-levelling points obtained from different measurement campaigns.
In 2008-2010 the preliminary results from the latest precise levelling sessions became available, leading to a significant increase in the number of precise GPS-levelling points. Both networks are part of the Estonian integrated geodetic network. Using very precise levelling connections from new levelling lines, normal heights of several RGP points were calculated additionally. Misclosure of 300 km polygons are less than 2-3 mm normally. Ealier all precisely levelled RGP points were included into fitting points. Now many new points are available for fitting and independent evaluation. However, the use of several benchmarks for the same RGP point sometimes results in a 1-2 cm difference in normal height. This reveals problems with the stability of older wall benchmarks, which are widely used in Estonia. Even we recognized, that 0.5 cm fitted geoid model is not achievable using wall benchmarks. New evaluation of the model Est-Geoid2003 is introduced in the light of preliminary data from new precise levelling. Model accuracy is recognised about 1.2 cm as rms.
The end of the 19th and the beginning of the 20th century frequently put forward the name of astronomer and geodesist Prof. Bernardas Kodatis, famous for his contribution to Lithuanian national ...revival, the establishment of the independent State of Lithuania, creating national systems of education and the history of economic and cultural restructuring of the country. Prof. Kodatis was born and matured in Potsdam and Berlin, in German environment (his great grandfather was a Samogitian). Yet at a gymnasium, Bernardas made up his mind to be a Lithuanian, to toil and fight for the sake of Lithuania Minor, Greater Lithuania and national qualities. However, up to now, no exhaustive research generalizing his life and work activities, except for the monograph of the present author (Algimantas Liekis. Prof. Bernardas Kodatis: The Life of the Returned Lithuanian V. 2010. 410 p.) has been proposed. The questions discussed in his papers, their importance to the sciences of geodesy and astronomy in the process of creating Lithuanian education system as well as the extent of his activities significant for Lithuanian nation and the State are attempted to be answered in this article. Also, particularly relevant biographical facts and fundamental moral principles used as guidance for the personal life of Prof. Kodatis are considered.
The article describes a method for deriving the precision of a predicted land uplift value at an arbitrary terrain point which is assumed connected in height to a levelling benchmark using GNSS and a ...precise geoid model. We derive a statistical model for predicting the uplift rate from the existing point rates along with its empirical signal covariance function. One of our aims is a study on how a land uplift rate model and its empirical covariance function can be determined and then used for calculating changes in height over the time interval between precise levellings or GNSS heightings.

Design engineers prefer working with actual ground distances. Therefore, the points of building site network should have the coordinates of the national grid system and the independent site grid ...system ("flat Earth"). The site network is usually formed and adjusted as a closed loop traverse (or triangulateration braced quadrilaterals or polygons with a central point) that commences from the first point with a direction angle of the baseline. These conditions cause some special requirements and methods of traverse adjustment and orientation (or other type of a network). This study determines the allowed deviation of baseline orientation from its ideal values of a typical building site network.

GNSS-instrumente (angl. Global Navigation Satellite System) uvrščamo med standardno terensko geodetsko mersko opremo (poleg elektronskih tahimetrov in nivelirjev), ki jo lahko uporabljamo za ...vzpostavitevgeodetskih mrež in za detajlno izmero. Podobno kot pri drugih geodetskih instrumentih moramo tudi pri GNSS-instrumentih pred izmero ovrednotiti parametre kakovosti instrumentarija oziroma metodeizmere, ki jih pridobimo s postopki laboratorijske kalibracije in/ali s terenskim preizkušanjem. Tako pridobimo podatek o ustreznosti navedenih tehničnih značilnostih proizvajalca in ovrednotimo primernost uporabe GNSS-instrumentov za konkretne potrebe.Mednarodna organizacija za standarde ISO (angl. International Organization of Standardization) je v okviru tehnične skupine 172 in podskupine 6 (ISO/ TC 172/SC 6) v letu 2007 predstavila postopkepreizkušanja GNSS-merskega instrumentarija za določanje položaja v realnem času, ki temeljijo na oceni kakovosti delovanja strojne in programske opreme posameznega instrumenta. Preizkus lahko opravimo kjerkoli na terenu, kjer so zagotovljeni primerni pogoji za izvedbo GNSS-opazovanj predvsem s stališča čim manjših vplivov na opazovanja zizvorom v okolici. Preizkus tudi ne zahteva dodatnega programskega orodja za obdelavo podatkov meritev, saj je statistično vrednotenje rezultatov opazovanj dokaj enostavno. V prispevku opisujemo teoretične podlage preizkusa GNSS-instrumentov po navodilih standardaISO 17123-8, ki jih uporabimo za praktični preizkus GNSS-instrumenta. ; GNSS-instruments (Global Navigation Satellite System) are the standard field surveying equipment (in addition to tachymeter and levels) for geodetic network establishment and detail surveying. As inthe case of other geodetic instruments, it is essential to pre-analyse GNSS-receiver quality parameters, obtained from laboratory calibration and/or field testing of the specific nstrument and/or measuring method. Thus, the relevance of the results, as indicated by manufacturer, is obtained that may explain the suitability of a specific GNSS-instrument for field measurements. In 2007, the International Organization of Standardization (ISO), Technical Committee 172, Subcommittee 6 (ISO/TC 172/ SC6), presented a comprehensive GNSS field testing procedures for real time measurements, based on statistical evaluation and verification of themanufacturer’s hardware and firmware. The test can be performed anywhere on the field assuming that the test area includes minimal potential influences to GNSS measurements. At the same time, a test does not require any additional processing software, because the test data evaluation is based on elementary statistics. This paper presents the theoretical basis of GNSS instrument testing in accordance with the ISO 17123-8 guidelines and further examination of specific measurements on the selected site.
The development of hardware increasing rapidly has made game developers take advantage of a variety of new resources that can improve their games. Epic games is a mature game developer who managed to ...make thousands game and delivered to the hands of gamers . A game engine called Unreal Engine is a big secret behind the success of Epic Games . The game engine is free if you just want to learn or just want to create a personal project and the game is not to be in comercial purposes . It is unfortunate that many students don’t even know of the existence of unreal engine , most of them make use of simpler game engine like game maker , rpg maker , fps creator , and so on. Though unreal engine is superior in any aspect other than the game engine , be it graphics , tools , mechanisms of development , flexible in export-import assets , etc . Based on this information , the author had the idea to make a first person shooter game using the unreal engine as the engine game. Before doing the develpment process, the next step is studying the literature of unreal engine and other supporting software such as 3d studio max to create 3D assets , adobe flash to create the menus , adobe photoshop to create a 2D texture and speedtree assets to create the foliage elements . The next thing is to go into the design phase of scenarios , maps, missions , characters and items that will be placed in the game. The next stage is the development and testing phase to test the game that has finished .The results of the design of this game is the realization of a first person shooter game application using unreal engine with features that can support the player 's interest in playing the game . It’s also introducing unreal engine to students who are interested in designing games.
