1 Name: Lab Section Lab Assignment #5 Topographic Maps: Map Scale & Distance, UTM Coordinates, Slope & Area Part A: Universal Transverse Mercator (UTM) Coordinates MAP SHEET:Mission, BC, 92 G/1, Edition 7, 1:50,000 (paper) View VIDEOSon 'Finding UTM coordinates of a feature'prior to answering questions that follow. 1)Provide the UTM coordinates for the following locations. Show all work for calculations. Three numbers should be calculated below; use a zero placeholder if less than 3 (e.g. '050' rather than '50'). (distance to symbol in mm / length of grid in mm) X 1000m = last 3 #’s of UTM in metres a)Campground at Rolley Lake Provincial Park (NW portion of map, north of Hayward Lake) Campground closestto the lake. b)Car symbol along Trans Canada Hwy (SW portion of map, NE of Aldergrove)c)Senior Citizen’s HomeNW of Yarrow (shown as a (SE portion of map, north of Vedder Mtn) large building)The black square building,west of the name label. d)Cemetery in Deroche (NE portion of map, north of Nicomen Island)

Identify the feature and neatly sketch the symbol located at the coordinates. (last three #’s of UTM in m / 1000m) x length of grid in mm = distance to measure to location in mma)10U 546800m.E. 5443750m.N. __________________________________ b)10U 557150m.E. 5429700m.N. __________________________________ c)10U 552200m.E. 5445350m.N. __________________________________ d)10U 556325m.E. 5431750m.N. __________________________________
3 Part B: Slope View VIDEOS on Slopeand Reading Contour Linesprior to answering question that follows. 3)Determine the slope in percent and as a degree (to 1 dp) from the spot elevation at 10U 548450 mE 5450900 mN to 10U 546275 mE 5451000 mN. Reminder:calculators must be in degreemode. Show all work. Beforecalculating the rise & run, ensure you’ve found the correct locations on the map. This is important! The upper elevation in this Q is a spot elevation; recall that a spot elevation is the exact elevation at a given location (often at the summit of a mountain) and is shown on a map as a ′dot′ with a number beside it. The lower location is on a contour line. To determine the elevation, find a contour line that has a labeled elevation then add/subtract the contour interval until you reach the lower location. Make sure to check if the landscape is rising or falling, as this will determine if you add or subtract the contour interval. Record elevations and distance from the map sheet below. Upper elevation = Lower elevation = Distance (ruler) = Rise: Run: Slope = rise/run Percent: Degree: Slope: %°
4 Part C: Calculating Area View VIDEOS on Areaprior to answering question that follows. 4)Calculate the area inside the yellow boundaryline of Matisqui Island(western side of map) to 1 dp. Includethe boundary line. Use the 0.5 cm grid graph paper (at end of assignment; also in Notes/Handoutsfolder). Submit grid paperwith tracingattached(taped to grid paper prior to counting; if tracing was drawn directly onto grid paper, then submit grid paper only). Show all work(including calculations for area of one gridsquare). Ground area of one grid = km2# whole squares # partial squares TOTALground area = km2 Part D: Map Scale & Distance View VIDEOS on Map Scaleand Map Distanceprior to answering questions that follow. 5)What is the ratio map scale on the Mission map sheet? ______________________ Show all workfor the following conversions. a)1 cm measured on this map is equivalent to ___________ centimetres (actual ground distance). b) 1 cm measured on this map is equivalent to _________ metres. c) 1 cm measured on this map is equivalent to _________ kilometres. d)If 19 cm was measured on this map, what is the ground distance in metres (to 1 dp)? Show work. m
5 6)Answer the following questions using a map scale of 1:60,000. Show all work.a)Convert the ratio scale to a verbal scale (i.e. put the scale into words). Remember to show the ground distance in appropriateunits (i.e. km, or m if < 1000m) _______________________________________________________ b)Present the ratio scale, 1:60,000, as a graphic scale. c)Calculate the ground distance in km (to 1 dp) between two locations on a map that are 18 cm apart. Use a map scale of 1:60,000. ________________ km
