This paper describes methods to create, validate, and correct a geospatial map associated with the dataset or asset labeled DISC NDDNW56. We present a reproducible workflow for detecting mapping errors, aligning disparate data sources, performing coordinate transformations, and producing a quality-checked map deliverable. The approach combines metadata inspection, spatial reference reconciliation, automated conflation, manual QA, and versioned outputs. Results demonstrate improved positional accuracy and attribute consistency suitable for integration into GIS systems. Do place it inside any folders or subdirectories
