What is the difference between a conformal projection and an equivalent projection?
Depending on the kind of projection used, the distortion may be of angle, area, shape, size, distance, or scale. Equal area projections maintain a true ratio between the various areas represented on the map. Conformal projections preserve angles and locally, also preserve shapes.
What type of map projection would be used if you wanted to preserve the distance?
equidistant map projection
If you will be using your map to find features that are within a certain distance of other features, you should use an equidistant map projection. Projections preserve direction from one point to all other points. This quality can be combined with equal area, conformal, and equidistant projections.

Where is the central meridian in a conic projection?
Standard parallels are where the cone touches or slices through the globe. The central meridian is opposite the edge where the cone is sliced open. Conic projections are used frequently for mapping large areas (e.g., states, large countries, or continents).
Which is the most common type of conic projection?
Conic projections are used frequently for mapping large areas (e.g., states, large countries, or continents). Cylindrical Different cylindrical projection orientations: The most common cylindrical projection is the Mercator projection, which is the basis of the UTM (Universal Transverse Mercator) system.
