class devkit_f2c_planner.test_projection.FieldCentroidTest(methodName='runTest')

Bases: TestCase

setUp()

Hook method for setting up the test fixture before exercising it.

test_frame_is_anchored_at_first_corner()

Starting from the opposite corner puts the anchor there: centroid is (-50, -25).

test_anchor_maps_to_origin()

test_axes_point_east_and_north()

test_distances_match_great_circle_within_field_scale()

Equirectangular error stays under 0.01 % out to ~1.4 km from the anchor.
