These are fun, thought-provoking exercises to help you better understand the ideas presented in the chapter. Take a minute to complete any of the Try This activities that you encounter throughout the chapter. classify projected graticules by projection family.interpret distortion diagrams to identify geometric properties of the sphere that are preserved by a particular projection and.convert geographic coordinates to SPC coordinates.describe the characteristics of the SPC system, including map projection on which it is based.describe the characteristics of the UTM coordinate system, including its basis in the Transverse Mercator map projection.recognize the kind of transformation that is appropriate to georegister two or more data sets.estimate the magnitude of 'datum shift' associated with the adjustment from NAD 27 to NAD 83.calculate the change in a coordinate location due to a change from one horizontal datum to another.

explain the concept of a horizontal datum.

convert geographic coordinates between two different formats.

demonstrate your ability to specify geospatial locations using geographic coordinates.Students who successfully complete Chapter 2 should be able to: This chapter explores implications of these properties by illuminating concepts of scale, Earth geometry, coordinate systems, the 'horizontal datums' that define the relationship between coordinate systems and the Earth's shape, and the various methods for transforming coordinate data between 3D and 2D grids, and from one datum to another.Ĭompared to Chapter 1, Chapter 2 may seem long, technical, and abstract, particularly to those for whom these concepts are new. A second distinguishing property is that the Earth's complex, nearly-spherical shape complicates efforts to specify exact positions on Earth's surface.

One is that geographic data are necessarily generalized, and that generalization tends to vary with scale. ?","shared.cancelOrder":"Cancel Order","euDisclaimer.HeaderTitle":"Information on how Uber Eats ranks offers","euDisclaimer.Chapter 1 outlined several of the distinguishing properties of geographic data.
