You are going to use a website called ArcGIS.com to create a map to first show the places where your data collection took place and to present your beach height at the groynes data. GIS stands for geographical information systems and allows us to understand the relationship between various data sets and location.
How to use ArcGIS
- First you need to download the correct data files from the bottom of this page. Scroll down to find them. If you are doing the coasts investigation you need the two LSD files. If you are doing the urban investigation download the Southbourne and West Cliff files.
- Before you can use this file you must convert it to a ‘CSV’ file. Go to ‘File> Save As’ and then select ‘CSV Delimited’ from the file type menu.
- Go to http://www.arcgis.com/home/ and sign in using the username and password your teacher gives you.
- Click on make a map
- Now click on Add in the top left hand corner and then ‘add layer from file’ from the drop down menu.
- Now select the CSV file you created earlier.
- Now click import layer.
- You will have to select the longitude and latitude options from the drop down menu.
- A map should now have been completed. If you have any problems see your teacher.
You now have a map that shows the locations where the data was collected. If you want to you can play around with the change the symbol option from the drop down menu that appears when you put the cursor over the name of your file on the left of the screen.
You can take a print screen of this and add it directly into your project with a description explaining your sampling procedure- which was a stratified sample. Make sure that you include the legend, scale and add a description. You will also need to manually add a North pointer.
*You will spot there is an empty area for the final groyne, this can be filled in by the group who were studying terminal groyne syndrome.
For your controlled assessment you need to use a total of 7 different methods of data presentation, two of which have to be complex. These can include tables, maps, line graphs, bar charts, pie charts and so on. Two of your methods have to be complex and you can use ArcGIS to create a map with proportional symbols as one of these.
Now you are going to use ArcGIS map to present 1 of your data sets.
Follow these steps.
- If you hold your cursor over the ticked cell on the contents pane on the left hand side an arrow will appear.
- Click on the arrow.
- Select change symbols
- Then select size
- Then from the drop down ‘To show’ menu select the variable.
- Press apply and the size of your dots on the map will change to fit the data that has been collected.
- To improve your map alter the class size and change the symbol until you get something you are happy with.
- Finally print screen and add this to a word document with an appropriate heading. Again remember to include the legend, scale and add a North pointer manually.
- Now repeat the steps above for the other data files.
