Enum Constant Detail

GlobalCRS84Scale

public static final WellknownScale GlobalCRS84Scale

This well-known scale set is defined for global cartographic products. The integer scale is chosen for intuitive map representation of vector data. The scale denominator is just right near the equator.

GlobalCRS84Pixel

public static final WellknownScale GlobalCRS84Pixel

This well-known scale set is defined for global cartographic products. Level 0 map resolution of 2, the next level of the map is resolved to 1, and so on in addition to 2. The scale denominator and the resolution in degrees are just accurate near the equator. The map unit of this scale is the degree.

GoogleCRS84Quad

public static final WellknownScale GoogleCRS84Quad

This well-known scale set is defined for compatibility with Google Maps and Microsoft Live Map's projection and zoom levels. Level 0 represents the world with a 256x256 pixel block, and the next level represents the world as 2x2 256x256 pixels, and so on. The scale denominator is just right near the equator.

GoogleMapsCompatible

public static final WellknownScale GoogleMapsCompatible

This well-known scale set is designed for the CRS84 coordinate system using the quadtree pyramid structure. Level 0 represents the world with a 256x256 pixel block, and the next level represents the world as 2x2 256x256 pixels, and so on. The scale denominator is just right near the equator.

CUSTOM

public static final WellknownScale CUSTOM

Customized scale set.

ChinaPublicServices

public static final WellknownScale ChinaPublicServices

The scale set supports the scale level and screen resolution of China's geographic information public service platform electronic map data specification.

Method Detail

values

public static WellknownScale[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (WellknownScale c : WellknownScale.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static WellknownScale valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
