Modelling and Dissemination of Land Survey Data

Standardization of methods for collecting, processing and exchange of spatial data (and data in general) is a necessary prerequisite for faster, safer, and more efficient use and dissemination of data. Currently there are number of international standards which define concepts of spatial data exchange. The Land Administration Domain Model (LADM), besides a generic model for land administration systems, provides the support for modelling of relationships between cadastral data and land survey procedures. OGC Observations and Measurements (v2.0) (O&M) specification, also published as ISO 19156, defines a conceptual schema for observations and features involved in sampling when doing observations. LADM and OGC O&M are associateed through LADM class LA_Source, i.e. its child class LA_SpatialSource. This paper analyses the data models and the legislation related to surveying and manners of processing and exchange of survey results on various use cases in Croatia, primarily through LADM and OGC O&M.
