6. Conformal maps need accurate compass directions maintained
on the map (like the Mercator map).

Task 1. Read and memorize the following words and word-
combinations:

developable surface – розгортаючи поверхня;
radial lines – радіальні, колові лінії;

meridian’s intersection – точка перетину меридіану;

tangent – контактний;

indicatrix – індикатриса;
conformal projection – конформна проекція;
compromise projection – довіллльна проекція;
rhumb line – локсодрома;

latitudinal extent – протяжність по широті;
inboard – внутрішній, найближчий до діаметральної
площини;

spheroid axis – сферичні осі.

Task 2. Read and translate the text.
Text 2 Map projection classification

Map projections are classified by:
1) -by shape of normal graticule. It is based on meridians and
parallels when the central axis of the developable surface is oriented
north-south.

Three types of map projections are used to project different
developable surfaces. These include:
- Cylindrical projections are based upon the projection of a globe

onto a cylinder. A classic example of such projection is the Mercator
projection.
- A conical projection projects information from the globe onto a
conic surface. Meridians of normal conical projections are straight

radial lines. The parallels are sectors of circles that are centered in the
point of meridian’s intersection.
- Azimuthal or Planar projections project information from the

globe onto a flat surface when only a point of the planar surface
touches the globe. The projection plane is a plane tangent to the
