Information
has glosseng: The expression figure of the Earth has various meanings in geodesy according to the way it is used and the precision with which the Earth's size and shape is to be defined. The actual topographic surface is most apparent with its variety of land forms and water areas. This is, in fact, the surface on which actual Earth measurements are made. It is not suitable, however, for exact mathematical computations because the formulas which would be required to take the irregularities into account would necessitate a prohibitive amount of computations. The topographic surface is generally the concern of topographers and hydrographers.

has glossdeu: Als Erdfigur (oder auch Erdgestalt) wird eine mathematisch möglichst einfach definierbare Annäherung an die Form der Erde bezeichnet. Eine solche Bezugsfläche wird in vielen Bereichen der Geowissenschaften für Berechnungen und für Positionsangaben benötigt. Erste Gedanken dazu dürften bereits auf südamerikanische Hochkulturen, Indien und Babylonien zurückgehen, vor allem aber auf die ionische Naturphilosophie.

has glossfra: La détermination de la figure de la Terre, autrement dit létude de la forme de la surface externe du globe terrestre et de ses dimensions, constitue lune des tâches classiques de la géodésie. Elle fournit des informations essentielles pour la géophysique et la géodynamique théorique. Il convient de remarquer, cependant, quune surface générale est le plus souvent un objet géométrique auquel on nassocie pas de propriétés physiques particulières. Tel nest pas le cas de la figure de la Terre, que lon doit déterminer en faisant intervenir, dune manière ou dune autre, le champ de pesanteur terrestre. De ce fait, on doit associer à la forme géométrique des propriétés physiques : la plupart des surfaces quon définira pour représenter la figure de la Terre sont des surfaces de niveau, ou surfaces équipotentielles, autrement dit, des surfaces sur lesquelles le potentiel de pesanteur est constant.

has glossnld: De vorm van de aarde kan op verschillende manier berekend of gedefinieerd worden. De meest voor de hand liggende is op het eerste gezicht de vorm van het aardoppervlak (de topografie) met alle bergen en zeeën. Het aardoppervlak wordt bestudeerd door de fysische geografie, waarin meestal de vorm van het aardoppervlak gebruikt wordt. In de geodesie, waarin nauwkeurig langere afstanden en posities worden berekend, wordt dit niet gebruikt. Het zou namelijk veel te lange berekeningen en formules opleveren als elke onregelmatigheid in het landschap zou moeten worden meegerekend. In plaats daarvan wordt gerekend met modellen waarin de vorm van de aarde wordt vereenvoudigd tot een bol of ellipsoïde, ruimtelijke lichamen die makkelijk met wiskundige formules te beschrijven zijn.

has glosspor: A expressão figura da Terra tem variados sentidos em geodesia de acordo com o sentido em que for usado e com a precisão com que o tamanho e forma da terra devem ser definidos. A superfície topográfica actual é mais aparente com a sua variedade de formas de terra e áreas de água. Isto é, de facto, a superfície sobre a qual são efectuadas as medições da Terra. Não é prático, de facto, para cálculos matemáticos exactos, pois as fórmulas que seriam necessárias para tomar em conta todas as irregularidades teriam tantas variáveis que necessitariam de uma quantidade proibitiva de cálculos. A superfície topográfica é geralmente um assunto de topógrafos e hidrógrafos.

has glossslv: Oblika Zemlje je bila skozi zgodovino od antike dalje in je v določenem obsegu še vedno predmet mnogih razprav in znanstvenih preučevanj. Danes je za obliko Zemlje glede na naravo preučevanja moč navesti več različnih oblik. Planetova dejanska oblika, poimenovana geoid, ki je približek elipsoida, lasten samo obliki Zemlje, pa tudi kardioid, ki je na severnem tečaju izbočeno, na južnem pa vbočeno telo, veljata za najnatančnejši poimenovanji oblike Zemlje, a za vse namene nista primerni. Zato se za večino kartografskega dela in za druge na matematiko navezane raziskave uporablja oblika referenčnega ali Zemljinega elipsoida, ki ima geoidu enako prostornino, geometrično središče, kratko oziroma vrtilno os ter čim manjšo razliko med vsotama kvadratov razdalj.
