GPS Drawing combines art, travelling (walking, flying and driving) and technology and is a method of drawing that uses GPS to create large-scale artwork.

Drawing is a visual art that makes use of any number of drawing instruments to mark a two-dimensional medium. Common instruments include graphite pencils, pen and ink, inked brushes, wax color pencils, crayons, charcoals, chalk, pastels, markers, stylus, or various metals like silverpoint. An artist who practices or works in drawing may be referred to as a draftsman or draughtsman.

A small amount of material is released onto the two dimensional medium which leaves a visible mark—the process is similar to that of painting. The most common support for drawing is paper, although other materials such as cardboard, plastic, leather, canvas and board, may be used. Temporary drawings may be made on a blackboard or whiteboard, or indeed almost anything. The medium has also become popular as a means of public expression via graffiti art, because of the easy availability of permanent markers.

The visual arts are art forms that focus on the creation of works which are primarily visual in nature, such as traditional plastic arts (ceramics, drawing, painting, sculpture, architecture, and printmaking), modern visual arts (photography, video, and filmmaking), and design and crafts. Many artistic disciplines (performing arts, language arts, textile arts, and culinary arts) involve aspects of the visual arts as well as other types, so these definitions are not strict.

A changing concept. The current usage of the term “visual arts” includes fine arts as well as crafts, but this was not always the case. Before the Arts and Crafts Movement in Britain and elsewhere at the turn of the 20th century, “visual artist” referred to a person working in the fine arts (such as painting, sculpture, or printmaking) and not the handicraft, craft, or applied art disciplines. The distinction was emphasized by artists of the Arts and Crafts Movement who valued vernacular art forms as much as high forms. The movement contrasted with modernists who sought to withhold the high arts from the masses by keeping them esoteric.[citation needed] Art schools made a distinction between the fine arts and the crafts in such a way that a craftsperson could not be considered a practitioner of art.

The mineral graphite is one of the allotropes of carbon. It was named by Abraham Gottlob Werner in 1789 from the Greek γραφειν (graphein): “to draw/write”, for its use in pencils, where it is commonly called lead, as distinguished from the actual metallic element lead. Unlike diamond (another carbon allotrope), graphite is an electrical conductor, a semimetal, and can be used, for instance, in the electrodes of an arc lamp. Graphite holds the distinction of being the most stable form of carbon under standard conditions. Therefore, it is used in thermochemistry as the standard state for defining the heat of formation of carbon compounds. Graphite may be considered the highest grade of coal, just above anthracite and alternatively called meta-anthracite, although it is not normally used as fuel because it is hard to ignite.

There are three principal types of natural graphite, each occurring in different types of ore deposit:

1. Crystalline flake graphite (or flake graphite for short) occurs as isolated, flat, plate-like particles with hexagonal edges if unbroken and when broken the edges can be irregular or angular;
2. Amorphous graphite occurs as fine particles and is the result of thermal metamorphism of coal, the last stage of coalification, and is sometimes called meta-anthracite. Very fine flake graphite is sometimes called amorphous in the trade;
3. Lump graphite (also called vein graphite) occurs in fissure veins or fractures and appears as massive platy intergrowths of fibrous or acicular crystalline aggregates, and is probably hydrothermal in origin.

Highly Ordered Pyrolytic Graphite or Highly Oriented Pyrolytic Graphite (HOPG) refers to graphite with an angular spread of the between the graphite sheets of less than 1°. This highest-quality synthetic form is used in scientific research. The name “graphite fiber” is also sometimes used to refer to carbon fiber or carbon fiber-reinforced polymer.
