GIS Project Steps
1. Define problem and project goals2. Develop methodology and analysis flow3. Data inventory, input, manipulation, and management
4. Analysis and accuracy assessment5. Presentation
- Poster-sized map, - Journal paper, - PowerPoint presentation, etc.

Presenting Maps and Data
GIS 11
Presenting Maps and Data•Showing data to the general public should be simple and easy to read•Know your data
GIS 12
Presenting Maps and Data Population
GIS 13
Presenting Maps and Data Population per Square Mile
Map Layouts
GIS 15
ArcView Layouts
GIS 16
Printed Map Layouts
Concise Title•topic, place, time
Legend•Word “Legend” or “Key” not needed
Data Source•Source and date data was obtained
Population
0- 50,000
50,001 - 150,000
150,001 - 300,000
300,001 - 600,000
600,001 - 1,200,000
1,200,001 - 2,400,000

Map Elements
Scale •inappropriate for small-scale maps•not needed for familiar large-scale maps
Direction Indicator•north arrow - only for unusual orientations on large-scale maps•use geographic grid on small-scale maps
Photos / Images Neatlines

Map Scales
GIS 23
Dimensionless Map Scales•ratio that relates a unit of measure on a map to some number of the same units of measure on the earth's surface•1:25,000•tells us that 1 unit of measure = 25,000 of the same units on the earth's surface•1” on the map = 25,000 inches on the earth's surface •one meter or one yard or one kilometer or one mile would represent 25,000 meters or yards or kilometers or miles, respectively, on the earth's surface.

Large and Small Scale Maps
1:5,000 is large scaleLarge Scale Map Small Scale Map
1:50,000,000 is small scale
