How to use the editor
- Add points with + Add point, or Import list to paste many at once (from an AI assistant, a spreadsheet or a CSV).
- Give each point a location: type an address or a coordinate in the Location field and press Enter, click Place on map and then on the map, or drag the pin.
- Verify the spot with the satellite layer or the links under Verify & tools, then tick verified.
- Export image (green button) and download the PNG.
Location formats that are recognised
| Type | Example |
| Address | 221B Baker Street, London or Eiffel Tower, Paris |
| Decimal degrees (lat, lon) | 48.8584, 2.2945 – lon/lat order is corrected when it is unambiguous |
| Degrees-minutes-seconds | 48°51'30.1"N 2°17'40.2"E |
| Labelled | lat 48.8584 lon 2.2945, POINT(2.2945 48.8584) |
| Map links | Google Maps, Apple Maps, Bing Maps, OpenStreetMap, geo: URIs (short links like maps.app.goo.gl do not work: open them and copy the full URL) |
| EPSG code + x y | EPSG:28992 121000 487000 (Dutch RD), EPSG:25831 500000 5700000 (UTM), also SRID=28992;POINT(121000 487000) and urn:ogc:def:crs:EPSG::28992. Built in: 4326, 4258, 3857, 28992, UTM zones (326xx, 327xx, 258xx), 31370, 3812, 27700, 2154, 2056, 3035, 3006, 3067. x (easting) comes first; a swapped order is corrected when only one order fits the area of the system. |
| Dutch RD without code | X=107005 Y=426352 |
An address is only a centre point. It may be metres or tens of metres away from the real object. An AI's coordinate may be completely wrong. Always compare with the satellite layer or Street View and drag the pin to the right spot before you mark it as verified.
Categories
Categories give pins their colour and build the legend. Rename them, change the colour, or add new ones in the box above the list. Importing a list creates categories automatically.
Saving
Everything is kept in this browser automatically. Save writes a project file (.json) that you can open later or on another computer. Nothing is uploaded.
Export
Choose a size preset or a custom size, let the map fit all points or use the exact view you framed, pick a style, add a title, and download. The legend lists the categories in use. Map attribution is added automatically.
