Method Detail

test_toRadians

public void test_toRadians()

test_toDegrees

public void test_toDegrees()

test_metersLatitude

public void test_metersLatitude()

Cross check for some constants (on Earth).

test_approxMetersLongitude

public void test_approxMetersLongitude()
                                throws ParseException

Cross check for approximate meters per second of longitude at some known latitudes on Earth.

Note: The computed values are rounded off to integers (zero digits after the decimal) since we are comparing to ground truth actual meters per second of longitude but we are computing using a formula that does not adjust for the flattening of the Earth. This makes the test comparisons accurate to within 1m, which is sufficient to verify the calculation.

Throws:

ParseException

test_realMetersLongitude

public void test_realMetersLongitude()
                              throws ParseException

Cross check for meters per unit of longitude at some known latitudes on Earth.

Throws:

ParseException

test_distance_noDistance01

public void test_distance_noDistance01()
                                throws ParseException

A test with two points that are exactly the same.

Throws:

ParseException

test_distance_noDistance02

public void test_distance_noDistance02()
                                throws ParseException

Throws:

ParseException

test_distance_washingtonDC_greensboroNC

public void test_distance_washingtonDC_greensboroNC()
                                             throws ParseException

Note: The road distance by the most direct route (US 29) between Greensboro, NC and Washington, DC is 299 miles.
