Trend surface analysis

Worldwide temperature trend analysis source ↗

Trend surface analysis, also known as trend surface mapping, is a mathematical technique used in archaeology and environmental sciences such as geology and soil science. The method involves using low-order polynomials of spatial coordinates to estimate a regular grid of points from scattered observations such as archeological finds or soil survey results.¹
