Specific terms
Este método de interpolação é considerado flexível e robusto e procura expressar as tendências direcionais que os dados sugerem, evitando, assim, o efeito de “olho-de-touro”, resultado de interpoladores como o IDP (inverso da distância elevado a uma potência).

"bull’s-eye effect"
This commonly arises in interpolation by inverse distance weighting (IDW).
Sudden changes in value tend to give rise to circular regions in data plots which then look somewhat like a dartboard (with a bull's eye in the centre).
