code can be translated to a coordinate system

in the UK most commonly post codes

postcodes provide locations of increasingly small areas but not points

provide a spatial reference given a descriptive code

---

earth is assumed to be spherical

sphere divided into lines of longitude and latitude

angles drawn form a point in the centre of the sphere to points on the surface to provide angular reference

angles drawn form a point in the centre of the sphere to provide a spatial reference on a 3D plane

none

what does a spacial referencing system need?

Select the correct answer(s).  

(0/0)

---

data of the same scale (this may involve the conversion of data)

able to allow measurement of length, area and shape

sufficient data to perform a spacial reference

constant and stable

able to show points lines and polygons

none

issues with geographic spatial referening

Select the correct answer(s).  

(0/0)

---

lines of latitude and longitude on projected maps are distorted so may be highly irregular

issues of precision

assumed the earth is spherical

distance between lines of latitude and longitude get less at poles

unmatched scales

lack of accuracy due to the vast quantities of data required

none

advantages of rectangular coordinate systems

Select the correct answer(s).  

(0/0)

---

x,y coordinates match with the x,y coordinates on a computer screen

easier to undertake spatial computations (distance direction ect)

location data can be given in km

especially useful in GIS

location data can be given in metres

rectangular cartesian grid laid over a projection of the earths surface

if grid is applied to too big an area the difference between grid spaces and geographic space varies greatly across area

grid lines will vary according to lines of longitude and latitude

grid lines will be constant and regular across the earths surface

none
