How To Draw A Rolled Map

Maps take been a part of human civilization for millenia. Whether it's to show terrain details in training for invasion, plotting trade routes across oceans, or even how to go from one station to an other, maps can exist used for many purposes. At present you can larn how to draw your own!

1. 1

   Employ a topological map to display routes. A topological map only shows routes from one point to another. It ignores any scale or even the real-life positioning of the locations. Probably the all-time example is the London Underground map.

2. ii

   Do some planning. To draw a topological map, yous need to draw a symbol for each location, and a bunch of lines connecting them together (representing the routes between them). You need to programme this out so that yous don't end up with a mess of lines. Think: the position of the objects on the map does not have to correspond to their real-life locations.

3. iii

   Make some sketches. Endeavour sketching it in different ways. It will help yous to run across what y'all can change to brand it ameliorate. Endeavour making the routes different colours to make them stand out, apply unlike symbols for different types of objects, etc.

4. 4

   Depict a keen version. This is the version that yous will use as the actual map. Try to make information technology every bit neat as possible.

   Utilize a planimetric map to show scale/position. A planimetric map is drawn to scale with the objects in the correct positions, but shows no indication of tiptop. Imagine it like flight over the area and taking a photo. If you look at the photo, you can see where everything is in relation to each other, just considering it is 2nd, you lot tin can't see how loftier up things are.

2. 2

   Decide on a scale. Wide area maps usually apply one:25,000 (4cm = 1km) or 1:l,000 (2cm = 1km) or even bigger. A small-scale map may use something like 1:100 (1cm = 1m) or one:50 (2cm = 1m). Maps of really tiny stuff can use scales such as x,000:1 (1cm = 1 micron), but you'll probably never need to draw something like this (unless you need to draw a map of a estimator chip that does homework, or something similar).

3. 3

   Decide on a cardinal. Having a key makes it easier to put stuff on your map, without having to draw it out in miniature. Some usual symbols include bluish lines for rivers, squares for buildings, triangles for hills and mountains, etc.

4. iv

   Pick a reference point. As everything is drawn to scale, you demand to selection a reference signal (usually the middle of the map, or a prominent feature). Imagine it similar plotting a graph, you have to take an origin so that you know where the points are meant to go.

5. 5

   Decide which objects you lot want on your map. For each object, you need to know it's distance from the reference point and it's bearing (the angle between a line connecting the object to the reference point and a line connecting the reference signal to the North Pole. Measured clockwise from Due north).

6. 6

   Decide which management on your map is North. Describe a little compass on the map to show which way it is.

7. 7

   Use your scale to convert the real-life distances into map distances. Say you take an object 6km abroad, and your scale is 1:50,000. 6km = 6000m = 600,000 cm. 600,000/50,000 = 12. the object should be 12 cm abroad on the map.

8. 8

   Start cartoon the objects onto the map. Say you have an object 6km away at a begetting of 255 degrees. Using the scale, it should exist 12cm away from the reference point (see above). As the bearing is 255 degrees, information technology should be at an angle of 255 degrees clockwise from the North direction (usually towards the top of the map). You may wish to draw a faint pencil line from the reference point towards N. Mensurate the angles from this line. Think: bearings are always given as clockwise angles.

9. ix

   Add together a scale indicator. There are three ways of doing this (each example uses a scale of 1:50,000):

   • Draw a square grid in the background. The lengths of the sides of the squares correspond to some altitude, usually one kilometre. Make sure that you lot write down what this altitude is, somewhere on the map. For the example, the squares would be 2cm across.
   • Describe a scale bar on the map. This is a little bar, usually 1 or 2 cm beyond, labelled with how long it would be in real life. For the case, a calibration bar 1cm long would be labelled 1/2 km.
   • Write the calibration (1:50,000) somewhere on the map. Some maps utilize a combination of these methods (e.m. the Os maps of Britain apply all 3).

1. 1

   Describe a topographical map if height matters. A topographical map is similar to a planimetric map, but it shows the heights of objects above (and beneath) a chosen reference height, usually assumed to be sea level.

2. 2

   Draw a planimetric map of the area. This will serve as the footing for a topographical map.

3. 3

   Start plotting contour lines. A contour line connects areas of equal elevation. Make certain that they are well spaced (east.1000. every ten metres). Contour lines may not cross over each other. The closer they are together, the steeper the ground is. The only time profile lines are allowed to bear upon is at a cliff border, where the acme changes very rapidly.

4. iv

   Label the contour lines. Don't characterization every one, you'll be there forever. Ordinarily, only every five or 10 lines are labelled.

5. 5

   Place a dot at the highest points of hills. Label these dots with the pinnacle of the hills.

  You should use a central, which is a chart that tells the reader what the icons are.

• Although information technology'south non a necessity, when cartoon a topological map, try to draw it without the lines crossing each other.

• If you lot mess up, scrap it and kickoff again.

Thanks for submitting a tip for review!

• When drawing very large areas, in that location may exist some distortion. This is due to the curvature of the Earth. In this case, you'll demand some grade of projection (east.g. Mercator project) to make your map await more professional person.

To draw a simple topological map to display routes, first with some preliminary sketches so yous can map out each location. Draw a symbol for each location and add lines to connect them, which represent different routes that can be used. Try making the road lines unlike colors and then they stand out, and utilize a variety of symbols to stand for different types of objects. Once you've got everything worked out, create a final version of the map that'south as dandy every bit possible. For tips on making other kinds of maps, like planimetric and topographical maps, read on!
