Abstract
Abstract. The paper reviews that there are several issues and challenges in order to implement full 2D and 3D Spatial Data Infrastructure (SDI) in Oman. The state of current 2D SDI and 3D geospatial data has been investigated. Currently, Oman has made noticeable progress in 2D SDI but not yet in 3D domain. To date, there are no serious efforts and initiatives by the authority to materialize the 3D SDI. This paper ends by describing a framework for implementing the 3D SDI. We expect, these issues and challenges of 3D SDI in Oman can prompt better services for several potential users.
Highlights
The 3D geospatial tool and their related applications are considered as a trend in (GIS) for representing the reality in interactive 3D virtual environment. 3D is defined as "a representation of a threedimensional, real-world object in a map or a scene, with elevation values (z-values) which is stored within the feature’s geometry" (ESRI, 2017)
To address the challenges and issues that are related to geo-dataset, the government has established the Oman National spatial strategy (ONSS) and Oman National Spatial Data Infrastructure (ONSDI) strategy in 2014. This was under the Supervision of Supreme Council for planning (SCP), the Steering Committee (SC), Directorate General of National Spatial Data Infrastructure and the National Centre for Statistics Information (NCSI) to coordinate, facilitate and support sharing and utilization of geospatial information across multiple government organizations in Sultanate of Oman (NCSI, 2017a)
Framework for implementing the 3D SDI in Oman. It should be based on a clear understanding of the challenges and potential values of 3D SDI (Blomqvist, 2010; Xu et al, 2010; Kitsakis and Dimopoulou, 2016; Biljecki, 2017; Salim, 2017). 4.1 Degree of readiness for 3D geo spatial data infrastructure in Oman The study will be based on a questionnaire which will be sent to all the service organizations within the government, private sector and other users in the country, Oman
Summary
The 3D (three-dimensional) geospatial tool and their related applications are considered as a trend in (GIS) for representing the reality in interactive 3D virtual environment. 3D is defined as "a representation of a threedimensional, real-world object in a map or a scene, with elevation values (z-values) which is stored within the feature’s geometry" (ESRI, 2017). Most countries around the world have succeeded in applying 2D Spatial Data Infrastructure (SDI) for planning and infrastructure management (Ho et al, 2013; Alwardi, 2015). Employing the 2D GIS may not be a useful tool to analyze complex problems (Figure 1) and so there is an urgent need to shift to 3D GIS (Roić, 2012; Kitsakis et al, 2016). This means that efforts should be exerted to further study the possible functions of 3D SDI and its usefulness. Initial findings of the study are highlighted in section four by proposing a framework of Oman’s national 3D SDI
