Map Making Map Projections *Distortions
Making Maps Map Projections * Cylindrical Projection *Conic Projection *Flat-Plane Projection
Map Making Map ProjectionsAdvantagesDisadvantages Cylindrical Used by navigators b/c it shows true direction & shape Exaggerates landmasses at high latitudes Conic Accurate for areas w/ long east-west dimensions Not as accurate for areas that extend mostly north to south Flat-Plane Used by pilots and navigators b/c it shows true direction, area, & sizes Distorts shapes
