5. OS Map Skills Flashcards
compass
a device for determing direction (N,E,S,W,NE,NW,SE,SW)
countour line
faint red-brown lines drawn on a map connecting points of equal height
dispersed
a position where dwellings are far away from eachother
easting
the vertical lines running from the top to bottom
grid reference
a location on a map that is found using the northing and the easting
land use
the function of land – what it is used for
route
a particular way or direction between places
settlement pattern
the way that buildings and houses are distributed in a rural settlement
linear
structures that are built in a line, usually along a major transport route
northing
the horizontal lines running from the east to west
nucleated
buildings closely grouped together
site
the exact location of a place
situation
what surrounding features it has (man-made and natural)
symbol
a drawing used to represent different features
what features should be included in a map
*title
*scale
*north arrow
*key or legend
how to read grid reference
remember down the corridor, up the stairs
4 figure ⬇️
- start at the bottom left of the map and go up until you see the bottom left corner of the square you want, then write the number at the bottom down e.g. ‘5 5’_ _
- move north until you get to the bottom left corner of the square you want
3.Look all the way to the left of that square and write down that number after the first one e.g. 5 5 ‘7 8’
six figure ⬇️
- to do a six figure reference, you need to leave a space after both numbers e.g. 5 5 _ 7 8 _ (so you do what you do for the 4 figure)
- Estimate how many tenths across the grid it is and write that down e.g. 5 5 ‘9’ 7 8 _
- Estimate how many tenths up the grid it is and write it down e.g. 5 5 9 7 8 ‘5’
how do maps show height
contour lines
how to tell whether on a map it is steep or not
*if the contour lines are close together, the spot
is steep
*if they are far apart, the slope is gentle
how to measure straight lines
use a ruler and then use the scale e.g. 2cm=1km
how to measure curvy lines
- take a piece of paper or something like that
- Every time the road turns, draw a line on the paper and then after you finish, measure it
- use the way to measure straight lines
how can OS maps help us
*height of land (is it flat)
*open space (if any)
*natural features (rivers, mountains, forrest, coast)
*human features (settlement nearby, transport routes)
