Actual Approaches on the Water Utilities Data Models

In November 2017 the Technical Normatives about producing spatial datasets on public utility networks was approved and published by National Agency of Cadastre and Land Registration. Romania has undertaken the implementation of INSPIRE, so identifying the best ways to put it into practice is an essential step in the application of these rules. Currently there are developed models for water and sewerage networks, designed both using company software and open source software solutions. From cadastral and urban management viewpoint, it is very important that the utility networks to be correctly and complexly modeled, justifying the importance of presented analysis. Its importance is due to the fact that utilities networks are fundamental parts of the smart city concept, being integrated with the cadastral information. The implementation of concepts that lead to 3D modeling of standards-compliant utilities networks, while also offering open-source access, is a top priority, including at international level. The present article aims to analyze these models by highlighting their current status and defining important aspects.
