The main purpose of this project is build a GUI in Java to show earthquake information using Google map and add different earthquake features.

I added two features into my Earthquake city map:
-
The first one is when the user clicks on a city, the map will display a popup menu either on or off the map which displays a count for the number of nearby earthquakes and their average magnitude. You can check my screenshot to see this new feature. In addition, I also included more information of the clicked city and the earthquake which threat circle contains the city in the Eclipse console.
-
The second one is I drew a line between the clicked city and earthquake which is useful for the user to visualize the influence of the earthquake.
For the module 6 code deteils:
The main modification and extension I made is in the EarthquakeCitymap class and CityMarker class.
In the checkCitiesForClick() method of EarthquakeCityMap class, if the user clicked on a city, all the earthquakes' threat circle that include the city will be recorded and their location information will be added to a array list called lc (store the earthquakes' location information).
Then, I called the getProperties() method of city marker and returned a HashMap called prop. Then, I will put the earthquake information(magnitude, location, threat circle) into the prop which is be used in the cityMarker class.
In the meantime, I also print out the information of earthquake and city quake in the Eclipse console which will be easily read by the user.
In the drawMarker() method of cityMarker class, if the getClicked() is true, I will get the properties of this city marker using getProperties method. Since I have already store the information of threat circle earthquake information so I can use it right now to draw lines
between city quake and earthquake. Next, I use the ScreenPosition class to convert earthquake location to x, y coordinates in the screen. Then, I can use this coordinates to draw lines to show the relationship between city quake and earthquakes.
So this is a general technical description of extensions I have done. If anybody have questions about my implementation, feel free to contact me or pull request. My email address is song.923@osu.edu.
