Activity 1.3 Plotting a Point on a Map Using UTM Coordinates Date: Part of the SOS 7.hnimute t p graphic quadrangle 'napcd Old Fathh l Win ming (2015), . repo luced in F g. A1a. We are going to plot the location of the active vent of the Old Faithful gryser. As of mid Angust 2015, the tive vt located approximately at UTM coordinates 12T 513671 mE 4925032 N 13 14 924000mN Geyser Upper Spasmodi Geyser Geyser Basin Geyser Hill ton r: nemone ring old Old 4923000mNFaithfuFaithfu Faithfu "23 Geys Blu Ll 513000mE 514000mE Figure A1.3.1 1. Regarding a first look at the map in Fig.A1.3.1 o) Whatis the minimum casting on the map61 3000 5100mE. What edge of the map is bounded by the minimum easting (top, bottom, left, right)? ahnd b) What is the minimum northing on the map? 192600mN. What edge of the map is bounded by the (top, bottom, left, right)?ahn minimum northing (top, bottom, left, right)? MOYThin (e) is the central meridian for this zone to the east (right) or west (let) of this map area? Refer to Fig. 1.5 for 2. The yellow square that surrounds most of the map in Fig. A1.3.1 represents a horizontal area on the ground that is 1 km by 1 km in dimension, so we can use a side of that square as a bar scale. (a) As accurately as you can, measure the length of a side of this square in cm; we'll use the variable name a5 for this (b) We will use the variable name b5 for the number of cm in 1 km. 65cm (c) The fractional scale of this map can be found by dividing 65 by as-we'll call that result e5. The fractional scale is That means that 1 length unit of any sort (cm, for example) on the map represents length units of the same sort (cm) on the ground. 24

Explanation / Answer

2.a. nearly 8cm measured on scale.

b. 1km = 100000 cm

c. So 8cm = 100000cm

so e5= 100000/8

= 12500.

hence the scale becomes 1/12500 or 1:12500
