NPS inventory, with documented newer-source positions. The newest bulk direct-NPS monument-coordinate export located, published in 2003, contains 1,465 Gettysburg records. For 19 documented same-object cases, newer NPS Places points take precedence; four additional records use newer USDOT-hosted park-cartographer geometry. All original coordinates remain preserved. A focused view shows six existing government-source update records, including two unresolved legacy crosswalks. Nearby distinct monuments are never merged. NPS labels the inventory incomplete; this map preserves available source records and does not claim an exhaustive physical-monument census.

Little Round Top: 22 provisional flank correspondences, 6 unresolved
These are 28 source headings, not 28 newly accepted pins. Parent monument IDs and names are not unique physical-object identities.
How completeness and location accuracy will be established
- Reconcile an item-level inventory with distinct monuments, flank/position markers, tablets and other objects.
- Keep source snapshots and raw coordinates; cross-check identity before comparing positions.
- Record source, capture date, method, datum and accuracy separately. Hosting date is not survey date.
- Resolve conflicting names, shared IDs, missing inventory and outlying/property features.
- Join James’s photographs by verified identity, then test the map on desktop and mobile.
- Retain source dates and separate source-record identities. Do not move or merge nearby objects. Publication is blocked until independent accuracy, placement and completeness gates pass.
NPS’s public total of 1,328 monuments/markers and the broader 1,830 inventory description use different scopes. The 409, 1,465 and 1,518 datasets overlap; do not add or subtract them to claim coverage.
