Observations#

The observation layer is still alpha, but it already defines the core scene, sensor, and transform objects used for column and satellite-style workflows.

Observation models#

`stilt.observations.Observation`	One normalized measurement record independent of raw file format.
`stilt.observations.Scene`	A logical grouping of related observations, typically sensor-defined.
`stilt.observations.PointSensor`	Sensor family for point-like observations.
`stilt.observations.ColumnSensor`	Sensor family for column and slant-column observation geometries.
`stilt.observations.VerticalOperator`	Vertical weighting or averaging-kernel operator for one observation.
`stilt.observations.FirstOrderLifetimeChemistry`	Apply a first-order exponential lifetime decay to particle `foot`.

Geometry and weighting#

`stilt.observations.HorizontalGeometry`	Horizontal measurement geometry for one observation.
`stilt.observations.ViewingGeometry`	Solar/view geometry attached to one observation.
`stilt.observations.LineOfSight`	Physical line-of-sight geometry and sampling choices for one observation.
`stilt.observations.VerticalOperatorWeighting`	Apply a `VerticalOperator` to particle `foot` values.

Builders and grouping#

`stilt.observations.build_point_receptor`	Build a point receptor for one observation.
`stilt.observations.build_column_receptor`	Build a vertical-column receptor centered on one observation.
`stilt.observations.build_slant_receptor`	Build a slant multipoint receptor from observation LOS geometry.
`stilt.observations.group_scenes_by_time_gap`	Group temporally adjacent observations into scenes.
`stilt.observations.group_scenes_by_swath`	Group observations by `HorizontalGeometry.swath`.
`stilt.observations.group_scenes_by_metadata`	Group observations by a metadata field.
