NZL_GNS_GM5_foliation_dip_direction
This data layer is an interpolated grid of dominant foliation dip-direction (0-360 degree azimuth) in the Otago Schist, at 100m x 100m cell size. Structural observations used in the interpolation were derived from QMAP 1:250,000 mapping and local observations by Simon Cox (1:10,000 mapping for Nenthorn and Barewood) and Adam Martin (for Middlemarch CD16 1:50,000 sheet).

- 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.
