This study develops a corridor-scale land cover evidence base to support planning for the proposed Sidoarjo-Pasuruan rail connection in East Java, Indonesia, where continuing geomorphic and socio-spatial impacts of the Sidoarjo mudflow complicate infrastructure siting and right-of-way decisions. The objective is to quantify land-cover composition within the corridor influence zone and to identify land-use conflicts that may increase acquisition costs, environmental disturbance, or implementation risk. Very-high-resolution QuickBird imagery was geometrically corrected, integrated in a Geographic Information System (GIS), and classified using supervised procedures to delineate major land-cover classes relevant to linear transport infrastructure. Spatial analyses were conducted within a corridor buffer to summarize class-specific areas and to locate segments characterized by concentrated built-up land and other constraints. Results show that rice fields dominate the regional landscape, covering 26,335.15 ha (36.9% of Sidoarjo Regency), with semi-technical rice fields comprising the largest share at 25,339.48 ha. At the corridor scale, feasibility constraints are driven primarily by built-up land: residential areas within the land acquisition footprint account for 9.73 ha (19.75% of the required acquisition area), implying substantial social and compensation implications despite their smaller absolute extent relative to agricultural classes. Industrial land totals 1,901.74 ha, including 1,611.49 ha of non-agricultural industry, highlighting the need to avoid high-value economic zones where possible or to design targeted mitigation where avoidance is not feasible. Methodologically, the study demonstrates that very-high-resolution satellite mapping can improve delineation of narrow, heterogeneous corridor features, thereby enhancing transparency and defensibility of early-stage routing decisions in disaster-affected settings. The outputs provide an empirical basis for corridor screening, prioritization of segments for detailed engineering investigations, and proactive stakeholder and environmental management.
