First, in one browser window, log into ArcGIS.com and Create a new Map.
Next, in a different browser tab or window, bring up the map for the MegaCities GeoInquiry
Now, what if you want to use the layer 'Megacities' in your own map?
- In your map, click on Add > Search for layers
- In the top drop down, you see 'My Content'. Shift to 'ArcGIS Online'
- In the search box below the drop down, search for 'MegaCities'
- ...you'll see several options; which one matches the one used in the GeoInquiry?
Lesson: If you see something, you can usually get it.
Try to get a different layer: Let's say that you want the 'World Urban Sprawl' layer.
- Again, click on Add > Search for layers
- ...if it isn't there already, shift the drop down to 'ArcGIS Online'
- ... ...nothing shows up! Why? (answer: The file actually has a different name)
- To find the correct file name, go back to the MegaCities GeoInquiry and bring up the Description for the 'World Urban Sprawl' layer
- ...you will see that the file name is 'World_Urban_Areas'
- ... ... try searching for 'world urban areas' – did you find what you wanted?
Lesson: If you see something, you can usually get it...but you have to know what it's called
