Managing the Lagos megacity and its geospatial iperative

Lagos has assumed the Megacity status and it is projected to have its population doubled in the first quarter of this century. The Megacity has extended beyond the administrative boundary of the state, which is also one of the fastest growing urban agglomerations in the world. Information is the most vital component of urban management; however,...

The National Cadastre and Mapping Agency S.A. is the civil agency in Greece that is responsible for developing the Hellenic National Cadastre and supporting its operation. In additions, it is responsible for compiling, maintaining, and updating the basic cartographic infrastructure of the country, as well as, for disseminating the data stored in...

Adding 3d GIS visualization and navigation to the sparqlquery loop

3D environments allow advanced spatial navigation and visualization, but have traditionally provided limited support for performing non-spatial data analysis operations like filtering, joining, and integrating data on-the-fly. Linked Open Data provides advanced support for performing filters and joins over datasets that can be dynamically...

High-Frequency 3d Geomorphic Observation Using Hourly Terrestrial Laser Scanning Data Of A Sandy Beach

Geomorphic processes occur spatially variable and at varying magnitudes, frequencies and velocities, which poses a great challenge to current methods of topographic change analysis. For the quantification of surface change, permanent terrestrial laser scanning (TLS) can generate time series of 3D point clouds at high temporal and spatial...

Machine learning for spatial analyses in urban areas: a scoping review

The challenges for sustainable cities to protect the environment, ensure economic growth, and maintain social justice have been widely recognized. Along with the digitization, availability of large datasets, Machine Learning (ML) and Artificial Intelligence (AI) are promising to revolutionize the way we analyze and plan urban areas, opening new...

All in? Identifying and tackling private sector’s barriers to data sharing: A Perspective on geospatial data in the Netherlands

There is a drive to create an inclusive open data ecosystem, that includes public, private and academic open data [Loenen et al., 2021]. There is a lot of existing research in Open Government Data [Janssen et al., 2012; van Panhuis et al., 2014; Martin et al., 2013] and plethora of OGD in the Netherlands. Although the private sector produces a...
