  - STRICTLY_HONOR_UPPER_LEFT
```
@Nonnull
public static final GTOPO30Options STRICTLY_HONOR_UPPER_LEFT
```
    Uses the upper-left coordinates described in the ULXMAP and ULYMAP fields in the terrain format, rather than rounding the tile coordinates to whole degrees.
    
    GTOPO30 terrain data is typically distributed as multiple tiles, each of which describes a rectangular region of the Earth. The coordinates of these rectangles can be described in whole numbers of degrees. For example, the W180N90 tile covers the rectangular area from -180 degrees to -140 degrees longitude and from 40 degrees to 90 degrees latitude. These coordinates are not directly specified in the header file, however. Instead, the ULXMAP and ULYMAP fields describe the coordinates of the center of the northwest cell, and the XDIM and YDIM fields describe the size of each cell. From these fields, the northwest corner of the rectangle can be computed. However, due to rounding error in these fields, the intended whole numbers will not necessarily be computed precisely. For that reason, by default, the GTOPO30Terrain provider rounds the rectangle's coordinates to the nearest whole numbers. Setting the GTOPO30Options.STRICTLY_HONOR_UPPER_LEFT option disables this rounding and uses the values computed from the terrain data file.

  - toString
```
public String toString()
```
    Description copied from class: java.lang.Object
    Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.
    The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:
    getClass().getName() + '@' + Integer.toHexString(hashCode())
    Overrides:
    
    toString in class Object
    
    Returns:
    
    a string representation of the object.
  - equals
```
public boolean equals(Object o)
```
    Description copied from class: java.lang.Object
    Indicates whether some other object is "equal to" this one.
    The equals method implements an equivalence relation on non-null object references:
    - It is reflexive: for any non-null reference value x, x.equals(x) should return true.
    - It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
    - It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
    - It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
    - For any non-null reference value x, x.equals(null) should return false.
    The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values x and y, this method returns true if and only if x and y refer to the same object (x == y has the value true).
    Note that it is generally necessary to override the hashCode method whenever this method is overridden, so as to maintain the general contract for the hashCode method, which states that equal objects must have equal hash codes.
    Overrides:
    
    equals in class Object
    
    Parameters:
    
    o - the reference object with which to compare.
    
    Returns:
    
    true if this object is the same as the obj argument; false otherwise.

  - hashCode
```
public int hashCode()
```
    Description copied from class: java.lang.Object
    Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.
    The general contract of hashCode is:
    - Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
    - If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result.
    - It is not required that if two objects are unequal according to the Object.equals(java.lang.Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
    As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java™ programming language.)
    Overrides:
    
    hashCode in class Object
    
    Returns:
    
    a hash code value for this object.
