Abstract
Abstract. It is expected that by the year 2050, 66% of the world’s population will live in urban areas, necessitating the efficient management of land and urban space, namely the requirement for multi-dimensional land management systems (MLMS). In most countries, current LMS are two dimensional, representing the reality on a plane. This research aims at outlying guidelines designed for augmenting existing 2D LMS to multi-dimensional ones, by investigating theoretical (conceptual) and technical inferences related to the adding of the height dimension, the time dimension and the scale dimension (scale dimension may also refer to levels of details). Sustainable multi-purpose land management systems for serving various end-users is essential, therefore, our study is based on a Delphi questionnaire, which aims at understanding the perspective of diverse stakeholders and experts who may use LMS, as well as mapping their requirements and expectations from the LMS. Questions were categorized into two groups: i) theoretical, focusing on semantic and mathematical definitions; and, ii) technical, focusing on functionalities, databases, data collection, etc. As a preliminary assessment, responses of eight experts, from different fields and countries, to the questionnaire were analysed and summarized. The results are presented in this paper, including the main issues that experts pointed out, as well as suggested classes, fields, procedures and functionalities that might be required from a multi-purpose MLMS.
Highlights
Multi-dimensional land management system (MLMS) is a framework for achieving, handling and analysing the restrictions, responsibilities and rights (RRR) of land properties in space (Jaljolie et al, 2018), time and different levels of detail
This paper presents the preliminary outcome of this study, and the general guidelines that should be incorporated in the formalizing of MLMSs
Starting from the common points, we provide suggestions related to the data structure, processes, functionalities and queries that need to be embedded into multi-purpose MLMS
Summary
Multi-dimensional land management system (MLMS) is a framework for achieving, handling and analysing the restrictions, responsibilities and rights (RRR) of land properties in space (Jaljolie et al, 2018), time and different levels of detail. As the population is rapidly growing, land resources become scarcer and more valuable This leads to complex and dense urban construction, especially in industrial and commercial centers, which leads to overlap and integration of structures in space. To achieve this, advanced LMS are necessary, such as offering techniques for modelling multi-dimensional data, enabling the spatial analysis of urban space and operating engineering applications. Discussions about sustainable multi-purpose MLMS for serving various end-users have been raised, which might require different LODs and granularities. These urgent demands from LMS coincide with advances in technology that enable high performance of comprehensive and rich spatial analysis, functionalities, queries, and process on large data volumes
