- Statement
- This grid was created using the natural neighbours algorithm in ArcGIS, by converting each structural observation into its unit vector east-west and north-south components (direction cosines), interpolating separate sine and cosine grids from these components, dividing the grids (sin/cos) and inverting values using an atan function. To obtain final azimuths data need to be classified to distinguish the four (+ or -) possible values of cosine and sine values depending on whether the azimuth is 0-90, 90-180, 180-270, or 270-360 degrees.
