16. Satellite Image: cropped by Field boundary

An accurate (not pixelated) cut of the Satellite Image based on the defined Field boundary is available for various views such as RGB, NIR, EVI2, LAI, NDVI, GNDVI, IPVI, GCI, SAVI, OSAVI, NDWI, WDRVI, NDMI, MCARI, etc.

Each SatelliteImage contains an geoMaps object housing rendering details like url, color codes, classes, and name. These details are found within the field -> satelliteImages -> geoMaps attribute. The url specifically is used to display maps as a WMS layer.

To illustrate, output samples for NIR and WDRVI views have been provided below.

Near-Infrared (NIR), WDRVI, and WDRVI Contrast

The request format is https://api.geopard.tech/geo/map/reflect?TRANSPARENT=true&VIEWPARAMS=uuid:<field_uuid>&TIME=2020-07-22T17%3A50%3A22Z&BBOX=<minX,minY,maxX,maxY>&LAYERS=sentinel2_wdrvi_and_field&SRS=EPSG%3A900913&WIDTH=512&geopardApiKey=<geopard_api_key>.

Explanation of the URL parameters

Where the input attributes are:

1. VIEWPARAMS=uuid:<field_uuid> contains the uuid of the "Field";

2. TIME=2020-07-22T17%3A50%3A22Z has the data of the satellite image in the format YYYY-MM-DDThh:mm:ssZ (url encoded) and located in the "FieldSatelliteImagery" entity with acquisitionDate attribute;

3. BBOX=<minX,minY,maxX,maxY> contains the bounding box (url encoded) of the "Field" in EPSG:3857 projection;

4. WIDTH=512 reflects the output image size in pixels (the precise number is important only if it is used as a thumbnail);

5. geopardApiKey=<geopard_api_key> is coupled to the authorization option via API Key;

6. LAYERS=sentinel2_wdrvi_and_field reflects the style, the provider attribute located in the "FieldSatelliteImagery" entity.
