A Plan of the Cities of London and Westminster, and Borough of Southwark is a 1746 map of the City of London and surrounding area, surveyed by John Rocque and engraved by John Pine. Rocque combined two surveying techniques: he made a ground-level survey with a compass and a physical metal chain – the unit of length also being the chain. Compass bearings were taken of the lines measured. He also created a triangulation network over the entire area to be covered by taking readings from church towers and similar high places using a theodolite made by Jonathan Sisson (inventor of the telescopic-sighted theodolite) to measure the observed angle between two other prominent locations. The process was repeated from point to point. This image depicts all 24 sheets of Rocque's map. John Rocque and John Pine

The Nazca lines are a group of geoglyphs made in the soil of the Nazca Desert in southern Peru. They were created in two major phases – the Paracas phase (from 400 BC to 200 BC) and the Nazca phase (from 200 BC to 500 AD). The combined length of all the lines is more than 1,300 km (800 mi), and the group covers an area of about 50 km2 (19 sq mi). Most lines run straight across the landscape, but there are also figurative designs of animals and plants. Scholars differ in interpreting the purpose of the designs, but in general, they ascribe religious significance to them. The lines were designated as a UNESCO World Heritage Site in 1994. This is an aerial view of the geoglyph known as the "monkey", one of the most well-known in the Nazca lines. Photograph credit: Diego Delso
