Workflow overview. The pipeline has three stages. (1) Inputs and controls: build controlled TC DTM/LDEM and orthomosaics and assemble a control network with GCPs tied to LOLA. (2) NAC pair processing: seam-aware NACL/NACR coregistration, NACR transform, and local ratio-based normalization yield a seamless NAC mosaic per pair. (3) Multiview SfS and geodetic control: ASP’s parallel_sfs refines the initial DEM using six NAC mosaics; the SfS result is aligned to LOLA (globally and locally), and all NAC orthos are map-projected onto the final SfS DTM at 1 m pixel−1 to form the controlled orthomosaic. A full command-level flowchart appears in the Appendix, which is a full-resolution vector version for zoom-in viewing.
