The National CAD Standard (NCS) is a collaborative effort in the United States among computer-aided design (CAD) and building information modeling (BIM) users. Its goal is to create a unified approach to the creation of building design data.
Hatching (French: hachure) is an artistic technique used to create tonal or shading effects by drawing (or painting or scribing) closely spaced parallel lines.When lines are placed at an angle to one another, it is called cross-hatching.
GRASS has been under continuous development since 1982 [3] and has involved a large number of federal US agencies, universities, and private companies. The core components of GRASS and the management of integration of efforts into its releases was originally directed by the U.S. Army - Construction Engineering Research Laboratory (USA-CERL), a branch of the U.S. Army Corps of Engineers, in ...
The Unified Soil Classification System (USCS) is a soil classification system used in engineering and geology to describe the texture and grain size of a soil.The classification system can be applied to most unconsolidated materials, and is represented by a two-letter symbol.
Axonopus compressus is a species of grass.It is often used as a permanent pasture, groundcover, and turf in moist, low fertility soils, particularly in shaded situations. It is generally too low-growing to be useful in cut-and-carry systems or for fodder conservation.

The earliest record was made by the surveyor John Rowley in the year 1710.

Grass growth around the circle is promoted by the accumulated soil water, and in turn the termites feed on the grasses, slowly increasing the diameter of the circle. This behaviour on the part of Psammotermes allocerus amounts to creation of a local ecosystem in a manner analogous to behaviour of the common beaver .
