Challenges for Updating 3D Cadastral Objects using LiDAR and Image-based Point Clouds

Nowadays due to the increasing complex and multifunctional building environment in the urban areas it is required an accurate geometry and proper legal registration of the cadastral objects including third dimension and time aspect. 2D land-parcel data seems insufficient to address the variety of problems in high density residential areas. This...

Aspects of Representing LiDAR Data Used for Updating

Performing environmental spatial analysis requires the collection of base data and special data, subject to the type of analysis in hand, among this data of course LiDAR data can be of much usefulness, in our particular case mobile network data were collected to assess the usefulness of using it for updating some features of the base map that...

The use of 3D depth cycloramas in municipal processes

The use of digital panoramic imagery in processes at municipal and cadastral authorities has become common over the last decade. Applications are found among situational awareness, inventory of public areas, real estate valuation, assessment of permits and inspecting security risks. More and more the imagery is being used for measuring and map...

The potential impact on property and socio-economic development resulting from road transport corridors in Africa: A case study

Description of the paper A development corridor is important, particularly regarding its impact on future property development and socio-economic growth. The objectives of this study include the following: ? A theoretical overview on development corridors; ? A literature review on economic wealth creation within a broader region. The South...

Preconditioners for Linearized Discrete Compressible Euler Equations

We consider a Newton-Krylov approach for discretized compressible Euler equations. A good preconditioner in the Krylov subspace method is essential for obtaining an efficient solver in such an approach. In this paper we compare point-block-Gauss-Seidel, point-block-ILU and point-block-SPAI preconditioners. It turns out that the SPAI method is...

Multigrid for High-Dimensional Elliptic Equations

This paper discusses multigrid for high dimensional partial differential equations (PDEs). We present partial grid-coarsening strategies for excellent multigrid convergence in the context of elliptic PDEs. We show that the multigrid convergence rate can satisfactorily be brought down with the grid strategies proposed herein, coupled with...
