Newark (-74.523, 40.997) Singapore (103.458, 1.632)
The geodesic distance between Newark and Singapore 24,652.407192 km.
The Tissot circles are to measure and geographically illustrate the geometric distortion (linear, angular, and area) associated with various map projections.
A geographic coordinate system enable geographic data to use common locations of geographic features, imagery, and observation within a common geographic framework. Many of us use this coordinate system in what is called Global Positioning Systems (GPS) locations.
2.The Bonne Projection
The planar distance between Newark and Singapore is 74,175.640158 km. It differs from the true distance because it is larger.
The graticule on the Bonne projection map are complex curves connecting points equally spaced along each parallel and concave toward the meridian.
Properties of Bonne Projection:
Equal area projection
Curvature of the standard parallel is identical to a cone tangent at that latitude
Central meridian and central parallel are free of distortion
Projection is not conformal …show more content…
The UTM is a suitable projection for the following data because we are only mapping one UTM zone. UTM is designed for a scale error not exceeding 0.1 percent within each zone. Error and distortion begins to increase for regions that span more than one UTM zone. The shape of a UTM projection is conformal and has an accurate representation of small shapes having minimal distortion within each timezone. The direction of this data would be true to local angles, and scale is constant along the central meridian. UTM projections have a scale factor of 0.9996 to reduce any lateral
