This endpoint creates a lidartopdown task for annotating a collection of lidar Frames in top down, with vector geometric shapes. The available geometries are polygon, line, and point.
Given a collection of LiDAR Frames, and optional camera data, Scale will annotate the top down images with the specified geometries. The callback_url is the URL which will be POSTed on task completion, and is described in more detail in the Callback section. The attachments will be a list of links to external JSON files, each following the definition of a Frame.
