level of detail needed
how much does the map need to show, do you just need a GOAD map to show function of buildings, or just a general overview of Bolton?
nature of investigation
where is the investigation taking place? is it a field investigation or a classroom investigation?
stage of investigation
is the map being used to show the location before the investigation is carried out, or to present data?
size of area
are you investigating a small town or a city? the scale needs to be appropiate
nature of detail
how old is the map? if it is more than 2 you may have to check land use
need for an outline map
may have data added to it e.g. choropleth map
GOAD maps definition
large scale plans of CBDs and shopping centres in the UK of cities (first produced in 1980)
strenghts of goad maps
- useful for analysis of the distribution of certain shop types
- updated frequently so show changes over time
- enable ratios/proportions of different types of shops to be calculated
weaknesses of goad maps
- only show groundfloor
- can go out of date quickly
- don’t cover whole area of shops in a town/city
- categorising shops can be subjective
