8-28. In  developing  a  topographic  map, you do NOT need to consider any elevations or utilities outside the survey area. 1. True 2. False 8-29. The first step in developing a topographic  map  is  to 1. perform  a  reconnaissance  survey 2. run a traverse 3. gather  all  available  maps  and other  pertinent  data 4. perform  a  plane-table  survey 8-30. When performing the reconnaissance survey, what task should you be thinking  about  when  planning  a plane-table survey? 1. Appropriate  setup  points 2. Sufficient  number  of  stations 3. Both 2 and 3 above 4. Length of the traverse run 8-31. Traverse  stations  should  be numbered in what manner on the plane-table sheets? 1. In  ascending  order  clockwise 2. In  ascending  order counterclockwise 3. Same as the stakes in the field 4. In the order each station is reached 8-32. The plane-table work is the final step in the fieldwork. 1. True 2. False 8-33. When you are establishing horizontal  control,  what  other method  besides  random  traversing may be used? 1. Grids 2. Sextant 3. Transit  and  level 4. Theodolite 8-34. How many base lines should you establish for a grid network? 1. Five 2. Two 3. Three 4. Four 8-35. When  surveying  along  a  shoreline and there is no established trench mark,  which  of  the  following actions should you take to establish a temporary datum? 1. Take  rod  readings  at  hourly intervals 2. Take rod readings at high and low  tide,  then  average 3. Set up a tide gauge 4. Establish a TBM at the waterline Learning  Objective:  Identify  and interpret  Mercator,  transverse Mercator  projections,  and  military maps. A. Mercator B. Conic C. Gnomonic Figure 8A IN  ANSWERING  QUESTIONS  8-36  AND  8-37,  USE THE TERMS IN FIGURE 8A. 8-36. The  earth’s  surface  is  projected  on a plane tangent to the equator in this type of projection. 1.  A 2.  B 3.  C 8-37. The  earth’s  surface  is  projected onto a cylinder in this type of projection. 1.  A 2.  B 3.  C 55
