Reverse Geocode

Finds the nearest place or street address for each point and adds place, region, country, street, city and postcode columns. Works offline at city level, at street level with an address index you build, or through an online service you opt into.

Also known as: Coordinates to address

How it works

Pick the Latitude column and Longitude column and an Engine. Place (bundled, city/town level) finds the nearest place in the bundled GeoNames list and adds geocode_place, geocode_admin1 (the region), geocode_country and geocode_distance_m. Street (OSM address index) finds the nearest address point in the Address indexes you built and adds geocode_street, geocode_housenumber, geocode_city, geocode_postcode and geocode_distance_m. Online (keyed endpoint) sends the coordinates to an endpoint you provide after you tick the consent box.

Max match distance (m), 5000 by default, caps how far away the nearest match may be: past it the place or address fields are NULL while geocode_distance_m is kept, so a point outside your data reads as missing rather than as a confident address somewhere else. Set it to 0 only when you really want the nearest match at any distance.

Inputs and outputs

Settings

{
  latColumn: string
  lonColumn: string
  engine: "place"|"osm-index"|"online"
  maxDistanceM: number
}

Example

You have sensor coordinates and want a readable location per sensor. Pick lat and lon, keep Place with the default Max match distance, and use geocode_place and geocode_admin1 as labels on a Chart.

More in Geocoding and routing

• Geocode — Finds the latitude and longitude for addresses or place names and adds a point. Works offline at city level, at street level with an address index you build, or through an online service you opt into.
• Route — Works out the road route between each row's start and end point, with distance, travel time and the route line. By car, bicycle, foot or truck.
• Isochrone — Draws the area you can reach from each point within a time or distance, such as a 15-minute drive.
• Matrix — Works out road distance and travel time between every pair of points, or from each start to each destination. For example, drive time from every store to every customer.
• Map-match — Snaps noisy GPS points onto the road network, one matched path per trip or each point with its confidence.
• Optimize stops — Puts stops in the visiting order with the least total travel time or distance on the road, for one or several vehicles.
