Question 1 Report
During a map-skills lesson, students use Fig. 1 to locate a campsite on an orienteering course. The four-figure grid reference is read by going along the eastings first and then up the northings. The campsite symbol lies within one grid square. The enquiry requires a six-figure reference so that the location can be passed accurately to another group.
(a) State the four-figure grid reference of the square containing the campsite. [1]
(b) State why a six-figure grid reference is more precise than a four-figure reference. [1]
Answer Details
- (a) The campsite is in the square reached by easting 35 and northing 61, so its four-figure grid reference is 3561. Grid references are read along eastings first, then up northings. [1]
- (b) A six-figure reference identifies a position within a grid square because it uses tenths of both the easting and northing. A four-figure reference identifies only the whole 1 km grid square. [1]
