Geographic data
Types of Geographic data § Surveys § Photographs § Sketches § Numerical data (eg counting the number of a particular item in an area) § Brochures, tourism leaflets etc
Surveys § Ask members of the public some questions § Have to be prepared with questions beforehand § Ask the same questions of each person you survey § Be polite, explain who you are and what you are working on § Only ask 2 -3 quick questions: people are busy and you shouldn’t take up too much of their time.
Photographs & Sketches § Field sketching and field photography are fundamental parts of any field work investigation. Benefits of sketches: § You can annotate your sketch: add notes, create a legend, label items you want to draw attention to. Benefits of photographs: § Before and after shots could be taken to show differences before and after an event, for example a rain storm § Taking photographs of the same place at different times of the day can show changes, eg the change in traffic flow at a particular junction, the pedestrian flow across an intersection. § Can also add digital annotations afterwards, but would have to record these on paper during the fieldwork trip as well
Numerical data § Counting the number of a particular item in an area For example: § How many bins are located along Swanston Street: between Flinders & Collins; Collins & Bourke; § How many different types of facilities are located within some of Melbourne’s parks, gardens & reserves (eg playgrounds, public toilets) § How many drain pipes feed into the Yarra River between Princes Bridge (St Kilda Road) and Queensbridge St (bridge just before Casino); and Queensbridge St and Kings Way bridge
Numerical data § Can present in graph format afterwards to make comparisons (see example below) § Can also mark items on a map on the day of the fieldwork excursion § Have printed maps with you on the day to add annotations and rough sketches too No of bins 10 8 6 4 No of bins 2 0 Flinders & Collins & Bourke & Lonsdale Collins Bourke Lonsdale & La.

Brochures, tourism leaflets etc § Useful for seeing maps and locations of things, eg: parks; various items along water ways; public transport, cycle and walking routes. § Go to the Visitor’s Centre at Federation Square to collect these items
