Relief Map
The relief map is a map indicating hills and valleys by the use of different colors. The colors are indicated as follows:
- Color.LIGHT_GRAY if the elevation is less than -10 feet
- Color.GRAY if the elevation is greater than or equal to -10 and less than or equal to 1000
- Color.GREEN if the elevation is greater than 1000 feet
Examples:
int[][] mapData = new int[15][15];
Random gen = new Random(1234567);
for (int row = 0; row < 15; row++)
{
for (int column = 0; column < 15; column++)
{
// get elevations between -100 and 2000 ft
int elevation = gen.nextInt(210) * 10 - 100;
mapData[row][column] = elevation;
}
}
ReliefMap map = new ReliefMap(mapData);
int diff = map.maxDifference();
Text message = new Text(0, 180, "Difference: " + diff);
message.draw();
for (int row = 0; row < map.length; row++)
{
for (int column = 0; column < map[0].length; column++)
{
System.out.print(map[row][column] + " " );
}
System.out.println();
