Integrate and store 3D roads and terrain for navigation purposes

Modern navigation heavily relies on Global Navigation Satellite Systems (GNSS) and digitized road network databases, but faces limitations in GNSS-denied areas and complex 2D road netowrks. This project addresses these challenges by developing a methodology to create and store a comprehensive 3D road and terrain dataset for enhanced navigation....

Safety-driven road width estimations from vector data

In recent decades, it is well known that transportation systems have a crucial role in the economic development and social prosperity of modern societies. While road width can be considered as one of the most important factors of the road environments, there is no clear definition of it. To better understand this, we need to reconsider the width...

ISO 19650 standards in Web GIS for project's information management including GIS & BIM

In large and complex civil engineering projects, well-managed information enables easier and faster access to the required data when available. In the Architecture, Engineering and Construction (AEC) industry, professionals and data managers constantly seek to optimize the information management process to better collaborate in projects that...

CityJSON in combination with MongoDB, PostgreSQL and GraphQL

CityJSON is a JSON-based encoding for a subset of the CityGML data model and an alternative to the CityGML exchange-format. This new encoding reduces the data size and simplifies the usage. These files can be stored in relational and NoSQL databases. Relational and NoSQL databases have integrated JSON. CityJSON has therefore the potential to be...

An integrative workflow for 3D city model versioning

3D city models are continuously becoming more popular among practitioners due to the volume and versatility of information they contain, which makes them suitable to be used in various applications. However, there is no mechanism to allow maintaining them updated at the same pace that cities evolve, or when error correction is necessary,...

Simplification & Visualization of BIM models through Hololens

Augmented Reality (AR) is the technology that superimposes digital generated objects on the physical world. It has the potential to create new products and services,like visualizing future buildings or objects that will decorate a place, which creates new opportunities for applications in both the public and private sector. The architecture and...
