Crime Study. Using ArcGIS

You are going to use a website called ArcGIS.com to present your data on a map. GIS stands for geographical information systems and allows us to understand the relationship between our crime data and different locations in Putney.

How to use ArcGIS

  1. Go to http://www.arcgis.com/home/
  2. Click on make a map
  3. Write Putney, UK into the search window in the top right and hit the magnifying glass.
  4. Now click on Add in the top left hand corner and then ‘add layer from file’ from the drop down menu.
  5. You need to find the results from last week. They are in Coursework>Geography>Year 9>Crime Investigation 2013> Select the ArcGIS file relating to your class.
  6. Now click import layer.
  7. A map should now have been completed. If you have any problems see Mr Turner

You now have a map that shows the location of all your study sites. Print screen this map and add it into your document. Make sure you give it an appropriate heading.

Data Presenation

Now you are going to use this map to present one of your data sets (pedestrian count, noise level or environmental quality). Follow these steps.

  1. If you hold your cursor over the ticked cell on the contents pane on the left hand side an arrow will appear.
  2. Click on the arrow.
  3. Select change symbols
  4. Then select size
  5. Then from the drop down ‘To show’ menu select one of the 3 variables e.g. environmental quality.
  6. Press apply and the size of your dots on the map will change to fit the data that has been collected.
  7. To improve your map alter the class size and change the symbol until you get something you are happy with.
  8. Finally print screen and add this to your project with an appropriate heading.
