प्रश्न
Discuss the main properties of conical projection with one standard parallel.
उत्तर
A conical projection is one, which is drawn by projecting the image of the graticule of a globe on a developable cone, which touches the globe along a parallel of latitude called the standard parallel. As the cone touches the globe located along AB, the position of this parallel on the globe coinciding with that on the cone is taken as the standard parallel.
Properties-
- All the parallels are arcs of the concentric circles and are equally spaced.
- All meridians are straight lines merging at the pole. The meridians intersect the parallels at right angles.
- The scale along all meridians is true.
- An arc of a circle represents the pole.
- The scale is true along the standard parallel but exaggerated away from the standard parallel.
- Meridians become closer to each other towards the pole.
- This projection is neither equal-area nor orthomorphic.
