Courbes de niveauContour lines
This API provides contour line data for the Canton of Geneva, calculated from the 2023 Digital Terrain Model (DTM) with equidistances of 1, 2, 5, and 10 meters. Smoothing has been applied to produce a softer rendering of the lines. Contours at other equidistances can also be generated on request. The dataset is maintained by the Geneva cantonal land information system (Système d'information du territoire genevois) and is useful for topographic mapping, terrain analysis, and planning applications requiring elevation data at the local level.Les courbes de niveau ont été calculées à partir du Modèle Numérique de Terrain (MNT) de 2023 avec une équidistance de 1 mètre, 2 mètres, 5 mètres et 10 mètres. Un lissage a également été appliqué afin de donner un rendu plus doux. Une génération de courbes à une autre équidistance peut être effect…
