raster_value: Sample a raster band at each instant of a trajectory

trajectory_quadbins: Return the distinct QUADBIN cells at a zoom level covered by a trajectory

raster_tile_value_quadbin: Sample a Raquet raster chip along a trajectory using a QUADBIN cell for georeferencing

atRasterValue: Return the instants of a trajectory where the sampled raster value falls inside a float range

minusRasterValue: Return the instants of a trajectory where the sampled raster value falls outside a float range

eRasterValue: Return true if the trajectory ever samples a raster pixel value inside a float range

aRasterValue: Return true if every in-raster-extent instant of the trajectory samples a pixel value inside a float range
