An evaluation of marine geospatial data infrastructure (MGDI) by delphi-analytic hierarchy process (AHP) approach

Decision makings in the contexts of spatial data infrastructure (sdi) and marine geospatial data infrastructure (mgdi) are recently gaining attention in sdi literatures. both initiatives are multi-dynamic and complex in nature,thus exhibiting multi-criteria decision-making (mcdm) problems. yet,there is dearth of multi-criteria evaluation (mce) decision making framework. in this paper,major criteria for enhanced decisions about mgdi implementations are evaluated. these criteria sourced from literature,further adjudged through delphi experts group evaluations till consensus was reached on seven criteria. thereafter,pilot surveys for criteria weightage and ranking based on analytic hierarchy process (ahp) model were carried out,with respondents from marine stakeholders in malaysia. results obtained were assessed and compared with scoring procedure; data and information had the highest percentage while social criterion is the least ranked. the significance of these criteria in enhancing mgdi decision for numerous marine activities among the stakeholders are therefore highlighted through this study. © 2016 penerbit utm press. all rights reserved.
