The map shows every location (as polygons) and every find with GPS (as dots). Anonymized locations are not visible on the map.
Layers
- "Locations" are polygons of the location maps — active ones in blue, parent locations (those with sub-parts) in grey. Clicking a polygon or a row in the sidebar zooms in.
- "Finds" are the ~17,000 small dots (every single find with GPS). Click a dot to open a popup with the find number, thumbnail and link to detail.
- "Former" (opt-in) shows the NEEXISTUJE- prefixed locations as red striped polygons.
- Under "Finds" the "Hide deviated" sub-toggle drops dots outside the location polygon, or more than 5 m from the centre for polygon-less locations. The same threshold drives the three-band (green/amber/red) offset colours on the collection list and the find detail — amber = outside the polygon but inside one of the location-map image bboxes, red = outside every map. When you pick a specific location in the sidebar, the counts on both toggles narrow to that location's finds.
- Toggle state is saved in your browser, so the next visit starts where you left off.
Pan and zoom
- Zoom: mouse wheel or pinch on touchpad / mobile. Pan: mouse drag or finger drag.
- At higher zoom each location's detailed PNG overlay appears in the background (OpenStreetMap tiles + AOI).
Locations sidebar
- The sidebar on the right (a bottom sheet on mobile) lets you search by id, code or name. Clicking a row zooms to that location.
Arriving from other pages
- When you reach the map from a find detail or from the "Show on map" button in the Collection, the map auto-zooms to that find or location and highlights the matching dots.
- When the Collection filter is something other than location (a state, a year, a country, etc.), the button is deliberately missing — the results would be scattered across the world and the map wouldn't be useful.
