Transition of reference frames LV03 - LV95: Triangular network (CHENyx06 and FINELTRA LV)
This API provides data for transforming geospatial coordinates between the Swiss reference frames LV03 and LV95, based on the triangular network of the national survey (FINELTRA-LV), completed in the 1990s. The network allows conversion between the two systems with an accuracy of about a decimetre. It has since been densified by the cantons and consolidated nationally, forming the basis for the CHENyx06 transformation model. The dataset is maintained by swisstopo, the Federal Office of Topography, and supports geodata processing across Switzerland's national cadastral and survey infrastructure.The triangular network of the national survey (FINELTRA-LV) was completed in the 90's and has permitted to transform geodata from LV03 to LV95 and vice versa with an accuracy of about a decimetre. This network has been condensed systematically by the cantons in recent years, and then assembled by s…
