neg:
people don’t like questions from strangers - might not want to answer
groups like mothers with children unlikely to ask -which skews data as becomes biased with who is being asked questions
not everyone tells truth - ruins data as becomes incorrect

pos:
quick method of data gathering - data is easy to quantify (compare numbers)
can collect large sets of data - allows representative responses
easy to compare data as trends etc are easily noticeable

Question 2

perception studies - limitations and way around those

Answer 2

neg:
subjective as based on one person - becomes bias and can skew data
difficult to derive a conclusion if too many choose a neutral response

pos:
study can be incorporated into other methods of data collection as supports evaluation
data is simple to understand
quick way of gathering (extra) information

Question 3

rural land use mapping - limitations and way around those

Answer 3

pos:
accurate info as not biased
selected categories allows for easy comparisons

neg:
accessing land maps can be expensive
time consuming to gather data at different locations - laborious
access top rural land may be restricted - leaves gaps in data

Question 4

urban land use mapping - limitations and way around those

Answer 4

pos:
accurate info as not biased
selected categories allows for easy comparisons

neg:
accessing land maps can be expensive
time consuming to gather data at different locations - laborious
access top urban land may be restricted - leaves gaps in data

Question 5

pedestrian and traffic survey - pos/neg

Answer 5

neg:
even whilst using multiple sample points and timings of these counts it can be impossible to fully explain the movements of traffic/people
can be unsafe doing these counts - especially in busy areas

pos:
can combine traffic counts with other data such as estimation of car and bus occupancy rates - allows for better analysis
very easy to pinpoint the areas of maximum and minimum activity
