Tiled weather maps

You can get tiled weather maps in available parameters:

  • humidity – relative humidity;
  • prec – the amount of precipitation (in millimeters);
  • pressureMm– atmospheric pressure for this hour;
  • snowDepth – depth of snow cover;
  • soilMoisture – soil moisture;
  • soilTemperature – average soil temperature;
  • surfaceTemperature– average surface temperature;
  • temperature – average temperature;
  • waterTemperature – average water temperature;
  • windSpeed– wind speed;

Timeline

Firstly get information about the available time points for which you can get tiles. In the time field an ISO file is used, which includes information about the timezone. The list of such steps is called a "Timeline".

Request example:

Run in playground 


{
  tiles(request: { lat:  52.37175, lon: 4.89358 }) {
    temperature {
      steps {
        genTime

        time
        timestamp

        bounds {
          lat { min max }
          lon { min max }
        }

        resolution { x y }

        value
      }
    }
  }
}

Tiles

After the timeline is requested, you can get the tiles:

https://api.meteum.ai/raster-maps/temperature/tile?x={x}&y={y}&z={z}&for_date=1673773200&gen_time=1673948778

The endpoint returns tiled maps and requires the following parameters in the request:

  • for_date – step timestamp;
  • gen_time – generation timestamp.

The following optional parameters are also supported:

  • proj – tile projection, EPSG:3395 (default) and EPSG:3857 are supported.

Example of using raster maps in codesandbox.io, just paste your tokens into variables.
