Abstract

Land surveying is the process of determining the three-dimensional position of a fixed point on Earth relative to a certain reference frame. High accuracy positioning has been called for by the land mapping and surveying community ever since GPS’s initial adoption to achieve centimeter
level accuracies.

In this scene, High Accuracy Services (HAS), available since the end of January 2023 (public use Level 1), are considered necessary by the Land Administration sector for implementing
classical institutional services such as parcel subdivision, boundary determination, new building insertion in the map, coordinate reference systems update. In this scene, Galileo (the European Union's Global Navigation Satellite System) is expected to offer a new paradigm for HAS, through the advent of satellite corrections broadcasting on the native triple frequency plan.

In this context, the H2020 GISCAD-OV project, has as main objective to design, develop and validate an innovative and cost-effective HAS for Cadastral Surveying applications, based on GPS+Galileo E6 HAS and Precise Point Positioning-Ambiguity Resolution (PPP-AR) quick convergence techniques. To enhance the surveying functionality of the standard and support HAS, a new survey model is being developed, within the context of the revision of the ISO standard 19152 Land Administration Domain Model (LADM). To validate this proposal a series of pilots have been carried out around Europe, with the active participation of local professional surveyors.

This paper presents survey-related requirements that have been developed for LADM Edition II- Part 2; the survey model of the LADM as included in the Committee Draft (CD) of LADM Edition II Part 2 (ISO19152-2) that has been submitted to the ISOTC211 committee for review and the main results from two of the seven GISCAD-OV pilot campaigns that have been performed and their validation.
