datagen_crop_segmentation

Generates a dataset for crop segmentation, based on NDVI raster and Crop Data Layer (CDL) maps. The workflow generates SpaceEye cloud-free data for the input region and time range and computes NDVI over those. It also downloads CDL maps for the years comprised in the time range.

Sources

user_input: Time range and geometry of interest.

Sinks

ndvi: NDVI rasters.
cdl: CDL map for the years comprised in the input time range.

Parameters

pc_key: Optional Planetary Computer API key.

Tasks

spaceeye: Runs the SpaceEye cloud removal pipeline using an interpolation-based algorithm, yielding daily cloud-free images for the input geometry and time range.
ndvi: Computes an index from the bands of an input raster.
cdl: Downloads crop classes maps in the continental USA for the input time range.
