Ordanance Survey Flashcards
Slopes: Concave slopes
Widely spaced at the bottom and closer at the top
Measuring irregular shaped area
Count the amount of squares in area,
1/2 covered square = 1/2 square
Add together
Slopes: Compund slope
Some parts are steep and contour lines are close together while other parts are gentle with lines far apart
Scale: 1:50,000
Representative scale
Settlements: linear
Houses are built in a line alongside a road
Measuring a regular shaped area
Measure length,
Measure width,
Multiply together
Drainage patterns: trellis
Lots of right angles
Slopes: Convex slopes
Contour lines close at the bottom and wider at the top
Settlements: Nucleated or clustered
Houses are grouped together
Scale: Ruled line
Linear scale
Drainage patterns: dendritic
Like a tree - branches out
Settlements: dispersed
These houses are scattered around and isolated
Types of distance
Straight line
Curved line
Drainage patterns: deranged
Has drumlins, no set direction
Drainage patterns: radial
Straight lines out from a single point
