Offshore (novel)
Offshore (1979) is a novel by Penelope Fitzgerald. It won the Booker Prize for that year. It recalls her time spent on boats on the Thames in Battersea. The novel explores the liminality of people who do not belong to the land or the sea, but are somewhere in between. The epigraph, "che mena il vento, e che batte la pioggia, e che s'incontran con si aspre lingue" ("whom the wind drives, or whom the rain beats, or those who clash with such bitter tongues") comes from Canto XI of Dante's Inferno.

Lidar
Lidar (also written LIDAR, LiDAR or LADAR) is a surveying technology that measures distance by illuminating a target with a laser light. Although thought by some to be an acronym of Light Detection And Ranging, the term lidar was actually created as a portmanteau of "light" and "radar". Lidar is popularly used as a technology to make high-resolution maps, with applications in geodesy, geomatics, archaeology, geography, geology, geomorphology, seismology, forestry, atmospheric physics, airborne laser swath mapping (ALSM) and laser altimetry. What is known as Lidar is sometimes simply referred to as laser scanning or 3D scanning, with terrestrial, airborne and mobile applications.
History and etymology
Lidar originated in the early 1960s, shortly after the invention of the laser, and combined laser-focused imaging with radar's ability to calculate distances by measuring the time for a signal to return. Its first applications came in meteorology, where the National Center for Atmospheric Research used it to measure clouds. The general public became aware of the accuracy and usefulness of lidar systems in 1971 during the Apollo 15 mission, when astronauts used a laser altimeter to map the surface of the moon.
