    "conversionMethod": "The red SHADMAN D/S marker centre was read from vector SVG exports of GeoPDF pages 4 and 119. Each page point was transformed through that page's GeoPDF viewport, LPTS and GPTS control coordinates. The two independent results were 2.09 metres apart and were rounded to 31.53804, 74.32807.",
    "uncertaintyNotes": "Use a 75 metre positional uncertainty. The two transformations agree closely, but the source symbol has finite size, the map scale is 1:50,000 and 1:40,000, and the GeoPDF corner coordinates are rounded. This is not a surveyed asset point."
