<i>Google Earth Engine</i> (GEE) technology for determining priorities for disaster Safe Education Units (SPAB) in Sukoharjo, Indonesia

Abstract Flood catastrophes are a common occurrence in several parts of Indonesia. Flooding has an adverse effect on community activities and the educational environment. Geospatial technology is being used for disaster mitigation extremely quickly. The purpose of this study is to use Google Earth Engine (GEE) to create a map of flood susceptibility and priorities for the Disaster Safe Education Unit (SPAB) in Sukoharjo Regency, Central Java Province. River networks, SRTM Digital Elevation 30m, and Landsat 8 USGS image data are illustrations of the secondary data used in this study. Flood vulnerability maps, field survey data for verifying school conditions, and school point plotting data make up the main research data. The data utilized in this study were analyzed, and flood vulnerability was modeled using GEE with the indicator parameters of river distance, Topographic Position Index (TPI), Normalized Difference Vegetation Index (NDVI), and NDWI (Normalized Difference Water Index). Priority 3 (Very High and High), priority 2 (Moderate), and priority 1 (Low) are the first three priorities that are determined for SPAB schools based on the overlay results. The results show that 136 elementary schools, 26 junior high schools, 11 senior high schools, and 7 vocational schools are included in Priority III (28.72%), 208 elementary schools, 34 junior high schools, 15 senior high schools, and 19 vocational schools are included in Priority II (50%), and 96 elementary schools, 18 junior high schools, 2 senior high schools, and 6 vocational schools are included in Priority I (21.28%). Collaboration with the Education Department and the Penta Helix components—the government, academia, media, businesses, and the community—is necessary to determine SPAB.
