[Termes IGN] transformation de coordonnéesRésumé : (auteur) An exact and stable algebraic solution based on solving a quartic equation with respect to the cosine function of the reduced latitude is proposed to transform Cartesian into geodetic coordinates. The unique proper root of the equation appropriate to the transformation is chosen from all possible roots by rigorous analyses and the singular region of the transformation that in which there at least one component of the geodetic coordinates is indeterminate or non-single-valued characteristics are determined strictly. The new algorithm does not need any approximation and the instability problems incurred in other algebraic solutions are overcome. For practical applications, the algorithm performs comparably to that of [Vermeille, H., 2011. An analytical method to transform geocentric into geodetic coordinates. Journal of geodesy, 85 (2), 105–117.] and shows a certain superiority in the singular disc over Vermeille's algorithm.

[Termes IGN] utilisation du solRésumé : (auteur) This study presents the results from an experiment conducted in two peri-urban areas of Northern Ghana using Participatory GIS (PGIS) to identify land tenure and use rights on customary and statutory lands. P-Mapping was used to uncover indigenous knowledge on the changes in land ownership, land use rights and land-use types over ten years. The paper finds that properly trained local people can reliably delineate and indicate land rights and land uses in their environment on photomaps with little support from professionals. The experiment results show that PGIS can accelerate land adjudication processes on customary lands.

[Termes IGN] système d'information foncièreRésumé : (auteur) The fit-for-purpose rural cadastre has been implemented for several years in the Amhara region of Ethiopia. There are no internationally accepted methodologies to evaluate the efficacy of rural cadastral systems in developing countries. In this study, an evaluation framework was designed from the literature review and used to assess the quality of the rural cadastral system. A mixed research method was applied. Data were secured from the pertinent participants, and descriptive statistics was used to analyze the data. The findings indicated that the framework developed for the quality assessment was found to be an essential tool to evaluate the efficacy of rural cadastral systems. The study identified the strengths, weaknesses, opportunities, and threats of the cadastral systems of the Amhara region, which underpinned the understanding of the spatial, legal, and institutional arrangements and statuses. Further, this study identified sets of indicators and good practices of the system.
