This paper examines the requirements based design of the LADM Edition II. The requirements are the starting point for the Abstract Test Suite (ATS, Annex A in an ISO standard). The requirements/ATS can be used to assess if a given LADM country profile with a specific application schema is conformant with the LADM standard. The requirements are a...

Volumetric echocardiography can potentially give a more complete picture of cardiac dynamics than its two-dimensional (2D) counterpart. Current clinical volumetric imaging probes have relatively low frame rates, and often require ECG gating to stitch together an entire volume. This makes measuring fast dynamics of the heart as well as imaging...

Three-dimensional ultrasound has initially been used to address volumetric imaging for diagnostic purposes and represents the leading-edge technological orientation in both transducer and IC (integrated circuit) architecture and design. However, new applications are coming up like biomarker measurements, preoperative navigation, real time...

Intense exploitation of land in the vertical direction has brought up complex legal relations between different types of spatial units with various characteristics (e.g., land, marine, air, underground parcels, and infrastructure objects). Therefore, the use of 3D models is required to clearly represent real property and associated Rights,...

In our earlier study, the land administration system in Saudi Arabia has been analyzed to develop the initial country profile based on LADM. The testing and validation of the initial country profile have shown that only the necessary information has been covered, and there is much critical information related to the property registration still...

ISO standards, which are actually being applied, are subject to periodic revision, typically in a 6 to 10-year cycle. A UN-GGIM Meeting of the Expert Group on Land Administration and Management was held on 14-15 March 2017, in Delft and the main conclusion was that the revision of LADM was indeed needed in order to provide better tools to...

Cadastral databases have unique requirements not shared by other spatial databases: The third spatial dimension must be included, but visualisation using 2D software must also be accommodated. The majority of users of the Cadastre will use 2D software, and should be provided an “instant in time” plan view of the boundaries (with any 3D parcels ...

The visualization of cadastral parcels in 3D is a challenge, since legal boundaries are, in many cases, invisible in the real world; so how can we properly represent something that is not visible to our eyes? This paper uses the results from research looking into problems of occlusion and ambiguous perception (in terms of position, size and...

3D city models are being increasingly adopted by organisations in order to serve application needs related to urban areas. In order to fulfil the different requirements of various applications, the concept of Level of Detail (LoD) has been incorporated in 3D city models specifications, such as CityGML. Therefore, datasets of different LoDs are...

We retrieve transmission compensated subsurface primary reflections from the reflection response measured at the surface. This is achieved by filtering the reflection response. The application of this scheme does not require model information. In this process, the reflection response is convolved and correlated with itself. The result after each...

The Santos basin in Brazil suffers from strong internal multiples that overlap with primaries from the pre-salt reservoirs. We propose an adaptive double-focusing method for the removal of these multiples to obtain a correct image of the target area. The proposed method applies a form of source-receiver Marchenko redatuming to the reflection...

The increasing popularity of 3D city models in navigation, urban planning, etc.,<br/>necessitates application-specific and geometrically accurate and valid models. The concept of Levels of Detail (LoDs) indicate a model’s scale of adherence to its real-world counterpart. Highly detailed datasets often contain errors or require an exorbitant...

It is challenging to design and develop a cadastral system that supports digital cadastre, 3D and provenance. Digital cadastre encodes cadastral information in digital format like LandXML, which allows for automation and returns high productivity. 3D enables capturing and representing the third dimension, which is critical for the development in...

Technology has simplified the construction of a 3D cadastre by allowing rapid, remote capture of the data required for the graphic components of the system. Research into using 3D information generated from laser scanning, LiDAr and satellite imagery, and aerial photography for Building Information Management (BIM) has advanced considerably over...

We present a scheme for Marchenko imaging in a dissipative heterogeneous medium. The scheme requires measured reflection and transmission data at two sides of the dissipative medium. The effectual medium is the same as the dissipative medium, but with negative dissipation. We show how the measured double-sided data can be combined to obtain the...

The implementation of a 3D cadastre is work-intensive and expensive and legitimation of such expenses is necessary. A legitimate path of argumentation is that 2D systems fail to communicate complex legal situations correctly. Also, additional arguments can help to strengthen the position of 3D cadastres and provide support from other professions...

Urbanisation is regarded as a significant global trend. This means cities around the world will be accommodating more population. The population demands accommodations as places for living and business activities. Cities have limited land and therefore high-rise structures have become major infrastructures addressing the needs arsing from...

Recent advances in survey design have led to conventional common-midpoint-based analysis being replaced by the subsurface-based seismic acquisition analysis and design, with the emphasis on advance techniques of illumination analysis. Amongst them are wave-equation-based seismic illumination analyses such as the so-called focal beam method. The...
