| 🇬🇧 | 🇬🇧 |
| What is a Map? | This is a bird's eye view of a piece of ground, drawn to scale, at a given date. |
| What is a topographical map? | These are the maps with which map reading is mainly concerned. They show, in as much detail as their scale allows, the physical features of the Ground Rivers, streams, hills, valleys, woods, etc. Their purpose is to present a complete and accurate picture of the ground as it exists. |
| What are Contour Lines? | These are thin lines drawn on the map that represent height above see level. Usually brown red or orange in color. Each one of which joins up points of the same height. The closer the contour lines, the steeper the hill, the more far apart thy are the slope is gradual. |
| How does the Contour Lines increase in numbers? | Contour lines increase by 20M below 80M, however, is increased by 40M over 80M. |
| What is the correct way to fold/ care for maps? | Maps must be treated with care, otherwise they soon will become torn, dirty and creased so they are unreadable. The correct way to fold a map is like a concertina. |
| Describe Relief? | The term “Relief” describes the rise and fall of the ground (Hills & valleys). It is difficult to show on a map, which is flat surface. Various methods are used to show relief and the most important is the contour. |
| What are Marginal Information? | These are the information found around the margins (the area of paper surrounding the map). e.g. The name of the map, the scale, conventional signs, etc. |
| What are Conventional Signs? | These are signs / symbols drawn on a map to represent permanent features / objects on the ground. |
| What is Eastings? | These are parallel lines, which run from north to south (vertically) and increase numerically from west to east. |
| What is the Grid System? | The whole country is divided into squares. Which in turn are divided into progressively smaller squares. For map reading purpose only the smaller squares is of concern to the cadet. The map sheet is covered with a series of parallel lines called Easting & Nothings, which runs horizontally & vertically. |
| What is Northings? | These are parallel lines, which runs from east to west (horizontally) and increase numerically from south to north. |
| What is Eastings? | These are parallel lines, which run from north to south (vertically) and increase numerically from west to east. |
| What are the two ways in giving grid reference? | Four Figure & Six Figure Grid Reference |
| How should a Four Figure Grid Reference be given? | A count must always be made first along the lines that increases from west to east (Easting) and then from south to north (Northings). E.g. you give easting then northings. |
| How should a Six Figure Grid Reference be given? | Before finding a six figure GR. you need to know how to find a four figure GR. A six figure GR. is used to pin point a particular location on a map, while the four figure GR. shows a specific area. To find a six figure GR. a. Find the four figures GR. b. Set the figures on a piece of paper with a space between the Eastings and Northings e.g. 34 _13 _ You then make imaginary Eastings & Nothings lines within the four-figure square, numbering them 0 – 10. |
| Name the parts of a Silver Compass? | 1-HOUSING, 2- HOUSING, 3- COMPASS NEEDLE |
| Name the three North Points and where are the located? | 1- True North, actual geographical location of the north pole. 2- Grid North, North point found on the map. 3 - Magnetic North, the location of the magnetic needle on the compass. |
| What is Bearing? | A bearing is a method of indicating direction. It is the angle, measured in a clockwise direction, between north and a line joining two known points. |
| What are the ways to measure distances on a map and in what units are they measured in? | 1- BY RANGE This is measured in Meters or yards. To measure a distance by range is to measure from point A to B in a straight line. 2 - BY ROUTE This is measured in Kilometers or miles. To measure the distance by road/ route, it is very important to follow the curves on the road/ route between the two points (A & B). |
| What are the four cardinal Points and main intermediate points? | North, South, East and West (N.S.E.W) are the four main points of the compass and are referred to as the Cardinal Points. The intermediate points are Northeast (NE), Southeast (SE), Southwest (SW) and Northwest (NW). |
| Define what are convex slope? | A convex slope is one, which bulges outwards. If you are standing at the top of a convex slope you will not be able to see all the way to the bottom because of the outward bulge, which would obscure your vision. A convex slope is steep at the bottom and becomes gradual as you climb to the top. |
| Define what are concave slope? | A concave slope is one, which curves inwards. When standing at the top of the concave slope, you will be able to see all the way down to the bottom. A concave slope is gradual at the bottom and gets steeper as you climb to the top. |
| When is a map most accurate? | A map is absolutely accurate only at the time when it is drawn. If it is old, many changes could have been made to the land. |
