This walkthrough runs a first AgriSense map: a field boundary, a Sentinel-2 image, and a vegetation index. You need a linked GEE key before the toolkit unlocks.
Before you start
- A SINAG account and a working login
- A Google Earth Engine service key uploaded in Account Management
- Either a KML/KMZ of the field, or enough map knowledge to draw the parcel
-
Open the tools menu
Go to Platform tools. If AgriSense is greyed out, configure GEE first, then refresh.
-
Choose how to define the field
Click Access Toolkit. Pick Upload KML or Draw Feature. Drawing is faster for a single parcel; upload is better when you already have a boundary file.
-
Set analysis options
Use Vegetation Indices for NDVI / NDMI / NDRE / SAVI / EVI, or Image Analysis for true-color and related composites. Keep cloud cover around 20% unless you need a specific date.
-
Pick dates and name the shape
Set a start and end date that covers a recent clear window (one to two weeks is a good first try). Give the shape a name so reports stay identifiable.
-
Draw or confirm the polygon, then run
Close the polygon on the map (or confirm the uploaded KML). Submit the geometry. When the map loads, inspect the index, histogram, and summary stats.
Cloudy scenes look washed out or return few valid pixels. Raise the date range slightly or enable Sentinel-2 cloud masking, then fetch again.
