9. the differene in longitude between 155.50°w and 155.60°w (d2): d2- 10. use your general equation from part a6 to find the value of c2 (that is, the difference in longitude between 155.50 and the mlo c2- i1. determine the longitude of the mlo site (155.50°w2). 7.5-minute topographic quadrangle map of the lower geyser basin, wyoming (2015), is reproduced in fig. a1.22. on the topographic map, put a dot in the center of the blue oval representing the grand prismatic spring (fig. 1.3). we are going to build on what you learned in part a to find the utm coordinates of the center of the grand prismatic spring. 512 13 4931000mn 4931 grand prismat sprin 493mn 1930 512000me 513000mbe figure a1.2.2 1. regarding a first look at the map in fig. a1.2.2 (a) what is the minimum easting on the map? me. what edge of the map is bounded by the minimum easting (top, bottom, left, right)? (b) what is the minimum northing on the map? minimum northing (top, bottom, left, right)? mn. what edge of the map is bounded by the (e) is the central meridian for this zone to the east (right) or west (left) of this map area? (refer to fig. 1.5 for 2. the yellow square that surrounds most of the map in fig. a1.2.2 represents a horizontal area on the ground at yellowstone national park that is 1000 m by 1000 m (1 km × 1 km) in dimension. we can use a side of that square like a bar scale. (a) as accurately as you can, measure the length of a side of the yellow square on the map in cm; we'il use the variable name a3 for this map length. a3 (b) we will use the variable name b3 for the ground distance along one of the sides of the yellow square-1 km-bui expressed in the same units as we used for a3. that is, b3 is the number of cm in 1 km. there are 100 cm in 1 m. and 1000 m in 1 km- 63 cmi (c) the fractional scale of this map can be found by dividing b3 by a we'll call that result e3. the fractional scale is that means that 1 length unit of any sort (cm, for example) on the map represents e3 length units of the same sort (cm) on the ground
