Which types of projections are described below?
lines of latitude and longitude intersect at right angles on a projection map. the projection map is useful for planning air routes.

options: robinson, mercator, winkel tripel, or azimuthal equidistant

The correct answers are first blank, Mercator. The second blank, azimuthal equidistant.

The types of projections that are described below are Lines of latitude and longitude intersect at right angles on a Mercator projection map. The azimuthal equidistant projection map is useful for planning air routes.

German cartographer Gerardus Mercator was the first to develop the cylindrical map projector or Mercator projector in 1569. It was of much help for navigators. On the other hand, the azimuthal equidistant projection map shows equidistant projections. In a map like this, all of its points have proportional correct distances from the center of the map. It is a polar projection that shows the meridians.
