Abstract

The 2026 dry season on Biak Island coincided with El Niño and was followed by land fires, but public information, especially spatial land fire data for the island, is scarce. This study aims to document the development of a WebGIS for disseminating spatial information on the 2026 Biak Island land fires and to evaluate the interfaces of two WebGIS versions that present identical data. The data include CHIRPS rainfall, MOD16A2 evapotranspiration, ERA5-Land weather for the Fire Weather Index, NASA FIRMS hotspots (MODIS, VIIRS), METAR airport weather data, NDVI and NDMI from MODIS, the NBR, NBR+, and ATBI burned-area indices from Sentinel-2, and three land cover products. Data were processed with Python and Google Earth Engine, then published as a static site based on MapLibre GL in two languages, English and Indonesian. The evaluation used feature matrix benchmarking and website page load time measurements against the Alaska AICC Dashboard, SiPongi+, BNPB, Global Nature Watch, and Pantau Gambut, followed by an anonymous 15-question survey. Benchmarking results show both versions make 45 to 50 requests, fewer than AICC, SiPongi+, and Global Nature Watch (89 to 590) but more than Pantau Gambut (29 to 38). The survey of 14 respondents yielded overall scores of 3.86 for Version A and 3.71 for Version B on a 5-point scale and showed no clear difference on the seven comparison items. This study recommends maps that do not cover navigation on phones, an initial display language that follows the user's browser language, and simpler explanations for lay users.
