verde.profile_coordinates

verde.profile_coordinates(point1, point2, size, coordinate_system='cartesian')

Coordinates for a profile along a line between two points.

If on a geographic coordinate system, will calculate along a great circle. Otherwise, will use a straight line.

Parameters:

point1 : tuple or list

(easting, northing) West-East and South-North coordinates of the first point, respectively.

point2 : tuple or list

(easting, northing) West-East and South-North coordinates of the second point, respectively.

size : int

Number of points to sample along the line.

coordinate_system : str

The coordinate system used to define the points and the line. Either 'cartesian' or 'geographic'.

Returns:

easting, northing, distances : 1d arrays

The easting and northing coordinates of points along the straight line and the distances from the first point.

Examples

>>> east, north, dist = profile_coordinates((1, 10), (1, 20), size=11)
>>> print('easting:', ', '.join('{:.1f}'.format(i) for i in east))
easting: 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0
>>> print('northing:', ', '.join('{:.1f}'.format(i) for i in north))
northing: 10.0, 11.0, 12.0, 13.0, 14.0, 15.0, 16.0, 17.0, 18.0, 19.0, 20.0
>>> print('distance:', ', '.join('{:.1f}'.format(i) for i in dist))
distance: 0.0, 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0
