Abstract
Abstract. National Spatial Data Infrastructure (NSDI) refers to a framework of policies, institutional arrangements, technologies, data, and people that enables the sharing and effective usage of geographic information. This paper aims to present the development and current progress of NSDI in Bangladesh. In preparing this paper, we have reviewed several papers, documents and articles related to NSDI development in Bangladesh. We have also explored different spatial data sharing platforms of related agencies and departments. This study finds that, in last decade, there is substantial increase in the production and use of geospatial data in Bangladesh. However, due to the absence of planning and centralized spatial data infrastructure (SDI) system, there are duplication of efforts among different organizations in respect of spatial data production leading to wastage of time and financial resources. There is also problem of maintaining same metadata standard among different organisations creating difficulties in building and sharing spatial data. Against this background, in 2016, Bangladesh government has decided to develop NSDI. As there are some organizations already have developed geoportal so it is decided that existing platform will be used as NSDI initially. Based on this decision GeoDASH platform is being used at present. However, there are many challenges and much to develop the platform. Development of NSDI in Bangladesh is still under process and there are some challenges also. Overcoming the problems and challenges, full-fledged development and operation of NSDI is expected to support the achievement of SDGs in Bangladesh.
Highlights
Spatial Data Infrastructure (SDI) is a system of gathering, sharing and disseminating spatially refenced data and information in a coordinated manner with technological support in order to ease policy formulation and decision making to meet the societal needs in local, national and global scale (NoguerasIso, Zarazaga-Soria and Muro-Medrano, 2005; Pashova and Bandrova, 2017)
It has been recognised that proper utilization of National Spatial Data Infrastructure (NSDI) for public and other facilities is indispensable for the formulation or release of various plan proposals and operation/maintenance of infrastructure when establishing digital government and upgrading citizen services and it is expected that this will contribute to economic growth and a transition to an information society supporting the achievement of sustainable development goals (SDGs)
The functions that need to be provided to government institutions, private sector companies, including general users and academic institutions consist of Search, View, Delivery, Geo-processing and User Management
Summary
Spatial Data Infrastructure (SDI) is a system of gathering, sharing and disseminating spatially refenced data and information in a coordinated manner with technological support in order to ease policy formulation and decision making to meet the societal needs in local, national and global scale (NoguerasIso, Zarazaga-Soria and Muro-Medrano, 2005; Pashova and Bandrova, 2017). This document states that “National Spatial Data Infrastructure (NSDI) means the technology, policies, standards, and human resources necessary to acquire, process, store, distribute, and improve the utilization of geospatial data”. It relates NSDI as ‘‘National Geospatial Data Clearinghouse’’ meaning a distributed network of geospatial data producers, managers, and users linked electronically. An NSDI can be considered as a framework of technology, standards, policy, and collaboration among different organizations ensuring the access, sharing, exchange, and use of spatial data at national level in a country (Putra, Sekimoto and Shibasaki, 2019).
