8-48. You are using a military grid map and you provide a six-digit coordinate  for  a  location.  How accurately have you located this point? 1. Within a 1000-meter square 2. Within a 100-meter square 3. Within  a  10-meter  square 4. Within  a  1-meter  square 8-49. Figures 9-18 and 9-19 show some of the marginal information of the frid map. Which of the following items are part of the marginal information? 1. Index  to  state  boundaries 2. Latitude  and  longitude  of  the SW corner of the grid map 3. Both 1 and 2 above 4. Grid  north Learning  Objective:  Identify concepts of conic, gnomonic, and polyconic  projections.  Recognize characteristics  of  conformality. 8-50. In figure 9-20, what point is the apex of the cone? 1. North  Pole 2. South  Pole 3. Equator 4. 30th  parallel 8-51. What is the difference between a gnomonic  projection  and  a  conic projection of the polar region? 1. In  the  gnomonic  projection,  the cone is cut and flattened out to form a map; whereas, the conic  projection  will  appear  as is 2. In  the  gnomonic  projection,  the points  lying  close  together  on either  side  of  the  meridian along which the cone is cut will be widely separated on the map; whereas, the conic projection  will  give  a continuous and contiguous view of the area 3. In  the  conic  projection,  the cone is cut and flattened out to form a conformal map; whereas,  the  gnomonic projection  will  appear  as  is 4. In  the  conic  projection,  the cone is cut and flattened out to form a map; whereas, the gnomonic  projection  will  appear as is 8-52. A Mercator projection is useful as a navigational chart due to which of the following factors? 1. Directional  conformity  only 2. Distance  conformity  only 3. Distance  and  directional conformity 4. Distance  conformity  and  near directional   conformity 8-53. Conformity  for  projections  meets which of the following descriptions? 1. Meridians  are  parallel  to  each other and equidistant from parallels 2. Direction  is  relative  to  the point  occupied 3. Distance  is  proportional  to  the location 4. Distance scale is the same for north and south as east and west 57
