It is easy to buffer both the neighborhoods of interest, but to get the intersection requires a self-join of the table, creating one relation (``ps``) with just the "Park Slope" record and another (``cg``) with just the "Carroll Gardens" record. Note that the area of the intersection is in square meters because we are still working in UTM 18 (EPSG:26918).
Es fácil crear un buffer de ambos vecindarios de interés, pero para obtener la intersección se requiere un self-join de la tabla, creando una relación (``ps``) con solo el registro de "Park Slope" y otra (``cg``) con solo el registro de "Carroll Gardens". Observa que el área de la intersección está en metros cuadrados porque todavía estamos trabajando en UTM 18 (EPSG:26918).

A unit circle (circle with radius of one) should have an area of pi, 3.1415926... The difference is due to the linear stroking of the edges of the buffer. The buffer has a finite number of edges. Increasing the number of edges in the buffer will get the value closer to pi, but it will always be smaller due to the linearization.
Un círculo unitario (círculo con radio de uno) debería tener un área de pi, 3.1415926... La diferencia se debe al trazado lineal de los bordes del buffer. El buffer tiene un número finito de bordes. Aumentar el número de bordes en el buffer hará que el valor se acerque a pi, pero siempre será menor debido a la linearización.
