Here are the data collected by two geology students in their transect. You are to make a plot that shows the map view of their transect. The data were collected by measure the horizontal distance between two points and the bearing (angle measured in degrees from north) from the first to the second. Then they moved on to a new point and measure to it from the second point previously measured and so on.
Here is the location of their work:point number bearing (degrees) horizontal distance (m) comments 1 136 6.35 2 136 4.65 3 136 6.7 4 136 9.6 5 136 4.35 6 136 4.08 7 136 3.8 8 136 3.5 9 136 6.4 10 139 6.6 11 139 5.9 12 139 5.9 13 139 7.2 14 139 6.05 15 139 5.4 16 139 6.85 17 139 4.8 18 137 24.85 19 124 17 1 124 19.5 (new scale) 2 121 6.2 (3 was skipped) 4 131 28 5 131 35.8 6 133 7 7 129 27.7 8 129 28.8 9 130 29.4 10 135 29.8 11 135 29.9 12 136 29.9 13 132 29.8 14 137 29.8 15 133 22.5 16 133 1.2 17 133 4.6 (18 was skipped) 19 124 24.6 20 124 28.2 21 123 13.6 22 119 22 23 123 25.5 24 122 13.75 25 120 13.8 26 119 33.8 27 32 43 28 49 50 29 44 38.45 30 120 28 31 125 18.4 32 127 32.6 33 125 17.4 34 125 2 35 126 22 36 120 40.8 37 123 29.6 38 112 28.4 39 115 36.4 40 109 12.7 41 120 33.6 42 114 23.8 43 110 29 44 113 29.4 45 102 24.6 46 94 22.4 47 170 50 48 170 50 49 120 27 50 112 49 51 114 40.2 52 118 9 53 133 29 54 123 28 55 125 43 56 127 30 57 130 30 58 125 17 59 120 30 60 123 25 61 135 16.5 62 124 13 63 124 30 64 120 30 65 128 30 66 125 22.6 67 109 29.8 68 109 29.8 69 108 30 70 108 30 71 107 29.6 72 105 19.8
Here are two maps of portions of the transect showing the points plotted along with the basic triangles that are needed ("de" is delta easting and "dn" is delta northing). You can check the math of your spreadsheet with them. The point numbers are labelled with their number and their coordinates in parentheses). Note how the coordinate is the cumulative de and dn.
