Assessing SDI implementation scenarios to facilitate emergency mapping operations in the Dominican Republic

Abstract

The Dominican Republic (DR) is a small island developing state (SIDS) highly exposed to disaster-risk phenomena, such as earthquakes, hurricanes, etc. The Spatial Data Infrastructure (SDI) enables coordination and sharing of spatial information and services from multiple sources, while emergency mapping operations (EMO) help decision-makers build a common operational picture (COP) of impacted communities. Assessment of future scenarios for SDI implementation to meet emergency mapping goals requires the consideration of a wide range of stakeholders with different objectives. We make use of multi-actor multi-criteria analysis (MAMCA) in the case study of DR to evaluate government, private sector, emergency mapping team (EMT), and academia perspectives of three governance scenarios (Going-Concern, Increasing-Hierarchy, and Increasing-Network) for SDI implementation. Our findings suggest that the ‘Increasing Network’ scenario is the most suitable for SDI implementation. A well-coordinated inter-organizational network through a SDI should empower more stakeholders to participate in EMO. This work highlighted the increase of publicprivate partnerships as a key criterion to share costs and efforts to effectively support emergency mapping tasks. Findings reported herein could assist decision-makers in designing roadmaps to enhance SDI implementation in the DR. This knowledge will also support future studies/practices in other SIDS, which share similar natural hazards and development issues.
