A LOCAL SPATIAL DATA INFRASTRUCTURE TO SUPPORT THE MERAPI VOLCANIC RISK MANAGEMENT: A CASE STUDY AT SLEMAN REGENCY, INDONESIA

Abstract

This research aims to implement an application of a Local Spatial Data
Infrastructure (SDI) for evacuation planning of Merapi Volcano disaster. The
processes, problems and information flows in evacuation planning were examined.
Geo-collaboration Portal was customized in order to provide spatial resources for
decision makers. It is equipped with usable maps presentation and interaction tools
to support collaborative decisions. User group assessment was carried out to
evaluate usability of the application. The evaluation results showed that
collaborative portals on top of a local SDI can facilitate effective decision making
process and improve coordination among involved stakeholders in the
context of disaster preparedness and mitigation. Several aspects need to be
considered in order to achieve a functional local SDI e.g. availability and quality
of the spatial data, establishment of local regulations and standards, development
of metadata, and strengthening capable human resources.
