The additional option here is ``distance='manhattan'``. The default distance calculator is 'euclid', which is the straightforward as-the-crow-flies method. The optional distance calculator is 'manhattan', which can be a more appropriate method if one is following the lines of a grid rather than traveling in a straight line.
Здесь задается дополнительный параметр ``distance='manhattan'``. По умолчанию, расстояние измеряется по Евклидовой метрике, что лучше всего подходит для измерений по прямой линии. Другой способ расчета расстояния по метрике Манхэттена ('manhattan'), который больше подходит, если необходимо следовать линиям сетки, а не по прямой.

Now let us create a space and index for Manhattan-style spatial objects, which are rectangle-or-boxes that have a different way to calculate neighbors.
Теперь создадим спейс и индекс для пространственных объектов с метрикой расстояния городских кварталов (метрика Манхэттена), которые представляют собой прямоугольники-или-параллелепипеды; соседи для них рассчитываются иным образом.

The additional option here is ``dimension=3``. The default dimension is 2, which is why it didn't need to be specified for the examples of rectangle. The maximum dimension is 20. Now for insertions and selections there will usually be 6 coordinates. For example:
Здесь задается дополнительный параметр ``dimension=3``. По умолчанию, измерений 2, поэтому не было необходимости указывать данный параметр в примерах для прямоугольника. Максимальное количество измерений -- 20. Что касается вставки и выборки, здесь будет 6 координат. Например:
