@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.

public String toString()
java.lang.ObjecttoString 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())
public boolean equals(Object o)
java.lang.Object
The equals method implements an equivalence relation
on non-null object references:
x, x.equals(x) should return
true.
x and y, x.equals(y)
should return true if and only if
y.equals(x) returns true.
x, y, and z, if
x.equals(y) returns true and
y.equals(z) returns true, then
x.equals(z) should return true.
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.
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.

The general contract of hashCode is:
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.
equals(Object)
method, then calling the hashCode method on each of
the two objects must produce the same integer result.
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.)
