Purpose

To demonstrate:

• geolocation of artificially-generated IP addresses
• plotting the coordinates of the IP addresses with arbitrarily-assigned colours and icons
• display the data in tabular form alongside the map for further interrogation
• wrapping this into a user-friendly interface

How to

You can:

• zoom with the + and - buttons on the map (upper left), or with your mouse wheel
• toggle marker layers with the checkboxes on the map (upper right)
• measure distances and areas with the square-rule button on the map (upper right)
• click markers to get information about that point
• search, filter and sort a table of these data in the ‘Explore the data’ tab

Key

The icons and colours are arbitrary and have no intrinsic meaning.
