9.     ___ is similar to the Transverse Mercator  i)                 The

                      projection except that there is only one                      Transverse
                      meridian that touches the cylinder from the                   Mercator
                      globe.

                      10.  ___  attempts  to  minimize  distortions  in  j)                Conformal

                      equator is the single standard parallel.                      projections


                        III.  GRAMMAR REVIEW

                        Task 1. Transform the verb in the sentence from Active into

                        Passive Voice. Mind the word-order and the tense of the verb.

                        1. Surveyors  use  three  types  of  map  projections  to  project
                  different developable surfaces.
                        2. Geodesists  are  now  using  the  TM  projection,  because  it  the
                  most widely used projected coordinate system for world topographic

                  and navigational chart mapping.
                        3. A conical projection projects information from the globe onto a
                  conic surface.

                        4. Map-makers have to project a 3-D surface onto a 2-D map.
                        5. Maps  of  developable  surface  assume  distinct  orientations  of
                  projection developable surfaces.

                        6. Cartographers  will  use  mathematical  formulas  to  create
                  projections.
                        7. Navigational  maps  need  accurate  compass  directions
                  maintained on the map.

                        8. Equi-distant maps show the distance between points.


                        Task 2. What does the selected pronoun refer to.

                        1. Meridians  of  normal  azimuthal  projections  are  straight  radial
                  lines,  and  parallels  are  circles  that  are  centered  in  the  point  of  the
                  meridian’s intersection.
                        a)      circles             b) projections                      c) meridians

                        2.  An easy way of visualizing the distortion of a map at a given
                  point (P) is Tissot's indicatrix, which is an ellipse centered at a point.
                        a)      distortion                  b)ellipse             c) indicatrix

                        3. Maps that maintain the shape of objects are called conformal.
                        a)      maps               b)objects                  c) points
