Map To Define Latitude And Longitude Of The Centre

I am new to Java and i am doing an assignment to identify Class and Attributes from below example. identify 7 classes and its attributes from this scenario:

ABC Maps Maker produces electronic maps for global positioning systems. Every map needs to define the latitude and longitude of the centre of the map, together with the length and breadth of the map. A map also has a name, and a set of geographical features.

A geographical feature is something noticeable in a a map; e.g., a hill, or valley. Among the types of features are the following: trace features, track features and tract features. All features have a name that is displayed on the map next to the feature.

A trace feature has a coordinate point to indicate its location relative to the centre of the map.

Broadcasting stations, mountain peaks, and transmission towers, are examples of trace features. Every trace feature has a description associated with it. Examples of track features include roads, railways and rivers. Each track feature has a list of points that define its course, and a line pattern. The line pattern specifies the colour, and the thickness.

Like a track feature, a tract feature also has set of points, except that when drawn on the map, the last point is linked to the first point to enclose a complete region. Additionally, it has a fill pattern which incorporates essentially a colour. Recall that there is a class, Point, in the java.awt package - this can be used to hold the co-ordinate of a point
