Sago mapping in Papua for remote-sensing-based resource characterization: A review

Abstract

Sago palm (Metroxylon sagu Rottb.) is an important ecological, economic, and cultural resource in Papua, Indonesia.This review examines the development of sago research and mapping technologies relevant to its spatial characterization in Papua.The literature was synthesized thematically to identify major research patterns, methodological developments, and remaining knowledge gaps.Previous studies have generated substantial knowledge on sago habitat, biological characteristics, productivity, genetic diversity, and utilization; however, these findings remain spatially and thematically fragmented and are only weakly connected to spatial mapping.Meanwhile, mapping technologies have progressed from habitat-and vegetation-level assessment toward object-, stand-, and individual-plant-level approaches through high-resolution imagery, UAVs, hyperspectral data, LiDAR, and advanced classification methods.To address this disconnect, this review proposes a four-stage multiscale framework linking (1) regional habitat screening, (2) stand and crown mapping, (3) biological classification, and (4) productiveattribute calibration.The framework provides a basis for shifting sago mapping beyond spatial presence toward biologically meaningful information on stand characteristics and resource potential, supporting more effective inventory, management, and sustainable utilization of sago resources in Papua.
