![]() Sparsely distributed settlements-few settlements spread over a large area.Moderately distributed settlements- settlements moderate in quantity.ĝensely distributed settlements- high concentration of settlements(black dots).Railways, station, sliding, level crossing lines and railways lightĪ settlement is a place with housing units where people live together Motorable trucks- rough roads which are used by people on foot and by vehicles on dry season.Dry weather roads- which are used reliably during dry seasons.All weather roads- which are used all year round i.e.ğactory for manufacturing or processing a known commodity. Mill for maize, millet, wheat processing Roads ending abruptly into a forest estate used to transport logs to saw mills cement indicates cement is mined in that area Size of rivers-big or small-shown by thickness of blue lines.Natural drainage features include lakes, rivers, swamps, sea, rapids, water falls, cataracts, springs, deltas, fjords, sand or mud, and baysĪrtificial features include ponds, wells, boreholes, water holes, cattle dips, cattle troughs, canals, reservoirs, irrigation channels, aqueducts, water treatment plants and man made lakes. High moisture content in the river valley.Likely indications of the following in the area: seasonal streams, scrub or grassland due to low rainfall. Symbols are given as pictures of vegetation. Natural vegetation is classified as woodlands, thickets, scrubs or grasslands. Gentle slope is one in which land doesn’t rise or fall steeply G) Identify the land forms present in the area. hilly, mountainous, plain, undulating landscape, has many hills, isolated hills, etc.ī) State the highest and lowest parts of the area.Ĭ) Look out for valleys which are occupied by rivers.ĭ)ĝivide into relief regions such as plateau, escarpment and lowland.Į)Ğxplain the type of slop e.g. The mineral with the lowest production was fluorspar.Ī)ĝescribe the general appearance of the entire area e.g. The second leading mineral in production was graphite.ģ. Tedious in calculation and measurement of anglesĢ.Ěctual values represented by each component cant be known at a glanceģ.ĝifficult to accurately measure and draw sectors whose values are too small.Ĥ.Ĝomparison can be difficult if the circles represent values which are almost equal.Ģ. ![]() Shade the segments and then provide a key.Ĥ.Ğasy to interpret as segments are arranged in descending order.ĥ.Ĝan be used to present varying types of data.ġ. On the proportional circle for each year use a protractor and mark out the anglesĦ. Using a pair of compasses draw circles of different radii representing mineral production in Kenya between 19.ĥ. The lowest producers were France and West Germany with.ġ.ĝetermining the radii of circles by finding the square roots of the totalsģ. The second largest producer is USA followed by Russia.ģ. The main producer of commercial vehicles is Japan.Ģ. Small quantities or decimals may not be easily represented.ġ. Tedious due to a lot of mathematical calculations and marking out of angles involved.ģ.Ĝan’t be used to show trend/change over a certain period.Ĥ. minerals, population, etc.Ĥ.Ğasy to read and interpret as segments are arranged in descending order and are also well shaded.ġ.ĝifficult to interpret if segments are many.Ģ. Poor choice of vertical scale causes exaggeration of bars length leading to wrong conclusionsī)ĝraw a circle of convenient size using a pair of compasses.Ĭ)ğrom the centre of the circle mark out each calculated angle using a protractor.ĭ) Shade the sectors differently and provide the key for various shadings.ģ.Ĝan be used to present varying types of data e.g. Not easy to trace individual contribution made by members of the same barĥ. Tedious as there is a lot of calculation work involved.Ĥ. It doesn’t show the trend of components (change over time).Ģ.Ĝant be used to show many components as there is limited space upwardsģ. Total value of the bar can be identified easilyġ. There is easy comparison for the same component in different bars because of uniform shadingĤ.Ğasy to interpret because bars are shaded differentlyĥ. The subdivisions are placed in descending order with the longest at the bottom(coffee)ģ. Use values for components to subdivide the cumulative barħ. Plot the cumulative values for each yearĦ. Set cumulative totals for the data each yearĢ.ĝraw vertical axis(Y) to represent dependent variableģ.ĝraw horizontal axis(x) to represent independent variableĥ.
