Fetch vegetation-index statistics for any ad-hoc geometry - no registered field boundary required. This endpoint computes summary stats for pixels inside your geometry while ignoring cloudy pixels. Currently supported on Sentinel2 (S2) , Landsat (L4/L5/L7/L8/L9) and Planet (PS) providers.
This page follows GeoPard’s API patterns and authentication used across the GraphQL endpoints.
What you can do
Query vegetation indices for Point, MultiPoint, Polygon, and MultiPolygon geometries.
Choose imagery providers: S2, L4, L5, L7, L8, L9, PS.
Get date-stamped results per acquisition with:
cloudfree - fraction of your geometry that’s cloud-free, range of values from 0 to 1, where 1 means fully cloud-free.
value - statistics for the selected index computed only on cloud-free pixels, includes min, max, avg, mdn, var, std.
Optionally provide ranges array of index value ranges for calculating coverage statistics. When provided, the response will include a ranges field showing what percentage of the area falls within each specified range.
Area occupied by each color/range - based on index value (low => high)
Coverage percentage - 0..1 value per range representing surface percentage
Supported indices
EVI2, NDVI, RVI, LAI, OSAVI, SAVI, GNDVI, IPVI, GCI, WDRVI, RCI, SBI, MCARI1. Index definitions follow GeoPard’s vegetation index catalog used throughout the API.

Vegetation index to compute.
providers
[Provider!]!
✅
Any of S2, L4, L5, L7, L8, L9, PS.
startDate
String (ISO8601)
✅
Inclusive start, e.g. "2025-05-10T00:00:00.000Z".
endDate
String (ISO8601)
✅
Exclusive end or inclusive end depending on schema; match your other GeoPard queries.

A stringified GeoJSON of type Point / MultiPoint / Polygon / MultiPolygon (WGS84 [lon, lat]). Remember to escape the quotes inside the string.
ranges
[[Float!]!]
❌
Array of [min, max] pairs of index value ranges for calculating coverage statistics
Performance guidance
For Polygon/MultiPolygon geometries, keep date ranges tight (~10–15 days) due to processing time.
Timeout: 30 s. Use fewer days and/or fewer providers if you hit the limit.
For Point/MultiPoint, larger ranges are usually fine (points are lightweight).
