[Termes IGN] projection Universal Transverse MercatorRésumé : (Auteur) Although the set of Gauss-Kruger projection formulae recognized and used worldwide thus far is "the 2nd formulae ", which is limited to use within certain longitudinal zones, the recently discovered usefulness of "the 1st formulae ", which can be applied to extensive areas on the globe, has been understood from a new perspective. The formulae are favorable in view of the modern computer environment, in which they are of importance for recognizing details comprehensively, not only in the discipline of survey and mapping but also in geospatial information management. In this paper, I try to elaborate a comprehensive derivation of these formulae, including those for meridian convergence and scale factor, so that anyone interested in geospatial information management can understand them with minimum background knowledge.

[Termes IGN] transformation de coordonnéesRésumé : (Auteur) We define as Positional Accuracy Improvement the problem of putting together maps A and B of the same area, with B of higher planimetric accuracy. To do so, all objects in A might have to be slightly moved according to a mathematical transformation. Such transformation might ideally be of a specific type, like analytical or conformal functions. We have developed a theory to find a suitable analytical transformation despite it is not well defined because the only data available is the displacement vectors at a limited number of homologue control points. There exists a similar problem in fluid mechanics devoted on estimating the complete velocity field given just values at a limited number of points. We borrowed some ideas from there and introduced them into the positional accuracy improvement problem. We shall demonstrate that it is possible to numerically estimate an analytic function that resembles the given displacement at control points. As a byproduct, an uncertainty estimation is produced, which might help to detect regions of different lineage. The theory has been applied to rural 1:50.000 cartography of Uruguay while trying to diminish the discrepancies against GNSS readings. After the analytic transformation, the RMSE error diminished from 116m to 48 m. Other problems with similar math requirements are the transformation between geodetic control networks.

[Termes IGN] rumbRésumé : (Auteur) Mercator's map projection (1569) has often been regarded as a scientifically disinterested innovation in projecting the globe onto a plane surface. This paper argues that by resituating Mercator's career within the theological conflicts of the European Reformation, it is possible to identify a more moralised, stoic inspiration for the projection's creation. In particular, Mercator's preceding work on theology and chronology disclose other ways of interpreting the projection. The rhumb line is taken as a defining element of Mercator's theological geography.

[Termes IGN] seizième siècleRésumé : (Auteur) A brief description is given of the cartographic activity of John Dee, which involved the production of at least three manuscript maps in the years 1580-1583 in connection with exploration and imperial ambitions. The form of an idealized version of the unusual projection used in one of the maps dated 1580 is discussed and it is shown how it may be considered to be related to projections developed between antiquity and 1551. The precise form of Dee’s projection is investigated and the possible reasons why he adopted it are considered.

[Termes IGN] transformation de coordonnéesRésumé : (Auteur) The meridian arc length from the equator to arbitrary latitude is of utmost importance in map projection, particularly in the Gauss-Krüger projection. In Japan, the previously used formula for the meridian arc length was a power series with respect to the first eccentricity squared of the earth ellipsoid, despite the fact that a more concise expansion using the third flattening of the earth ellipsoid has been derived. One of the reasons that this more concise formula has rarely been recognized in Japan is that its derivation is difficult to understand. This paper shows an explicit derivation of a general formula in the form of a power series with respect to the third flattening of the earth ellipsoid. Since the derived formula is suitable for implementation as a computer program, it has been applied to the calculation of coordinate conversion in the Gauss-Krüger projection for trial.
