1. Request a file to export

Recommended retrieving only a single dataset with sourceDataUrl per request.
NoBuffer, PlusOnePixel, PlusTwoPixels, MinusOnePixel, and MinusTwoPixels are available as a buffer.
GEOJSON and GEOTIFF are available as a format.
1
query GetGriddedDataFromTopographyMap {
2
getFarms (farmUuids: ["<placeholder_of_farm_uuid>"]){
3
uuid
4
fields (fieldUuids: ["<placeholder_of_field_uuid>"]) {
5
uuid
6
topographyMaps(topographyMapUuids: ["<placeholder_of_topography_uuid>"]) {
7
uuid
8
sourceDataUrl(format: GEOJSON buffer: PlusTwoPixels)
9
}
