## What is a paper map called?

Cartography (/krtrfi/; from Greek charts, “papyrus, sheet of paper, map”; and graphein, “write”) is the study and practice of making maps.

## What is the distance thing on a map called?

A map’s scale indicates the relationship between the distances on the map and the actual distances on Earth.

## What is an example of a map projection?

Examples are: Azimuthal Equidistant, Lambert Azimuthal Equal Area, Orthographic, and Stereographic (often used for Polar regions). Other Projections include a variety of specialized or fanciful types.

## What are 2 types of map projections?

Types of Map ProjectionsGnomonic projection. The Gnomonic projection has its origin of light at the center of the globe. Less than half of the sphere can be projected onto a finite map. Stereographic projection. The Stereographic projection has its origin of light on the globe surface opposite to the tangent point. Orthographic projection.

## What are the 4 common map projections?

Types of Map ProjectionsCylindrical Map Projections. Cylindrical map projections are one way of portraying the Earth. Conic Map Projections. Secondly, conic map projections include the equidistant conic projection, the Lambert conformal conic, and Albers conic. Azimuthal Map Projection.

## What are the three planes of projection?

[FIGURE 3-2] Projections of the point are made onto three of the surfaces that make up the box: the top or “H” (horizontal) plane, the front or “F” (frontal) plane, and the right side or “P” (profile) plane.

## What is VP and HP?

VP: The plane in front of observer is the vertical plane. (VP) or it is also called a Frontal plane. HP: The plane which is Horizontal and perpendicular to VP is Horizontal Plane. Top View (TV): The projection on the HP is called the Top View (TV) or Horizontal Projection or Plan.

## What are the 3 principal views?

For this object three views are created: front, top, and right side. The views are aligned so that common dimensions are shared between views.

## What is 1st angle of projection?

First angle projection is a method of creating a 2D drawing of a 3D object. It is mainly used in Europe and Asia and has not been officially used in Australia for many years. In Australia, third angle projection is the preferred method of orthographic projection. Note the symbol for first angle orthographic projection.

## What is 1st 2nd and 3rd angle projection?

1. The object is placed in the first quadrant. The object is placed in the third quadrant. 2. The object is placed between the plane of projection and observer.

## Who uses 1st angle projection?

Orthographic Representation Third angle projection (figure 1.2) is used mainly in The United States and Canada whilst first angle projection (figure 1.1) is used mainly throughout Europe and the rest of the world.

## How do you read 1st and 3rd angle drawings?

For the first angle projection, place the object in the first quadrant and in the third quadrant for the third angle projection. The object is placed between the plane of projection and observer for the first angle projection and between the object and observer for the third angle projection.

## What is the symbol of Third Angle Projection?

Normally when drawing in first or third angle projection a symbol is drawn which clearly shows which angle of projection has been used.

## Why we use only first and third angle projection?

The viewed surface of the object that is drawn is said to be ‘projected’ through the object onto the view plane. This is the key element that distinguishes first angle projection from the other method of producing orthographic views of objects, third angle projection.
