| {{htmlJSON.Abstract}} | This tool computes both a continuous and a categorical TOBIA (Topography Bedding Intersection Angle) Index according to Meentemeyer & Moody (2000) For computation, a slope and a aspect raster (both in radians) determining slope face orientations are required. The categorical TOBIA classifies the alignement of a geological structure to Topography into seven classes:0) Underdip slope1) Dip slope2) Overdip slope3) Steepened escarpmemt4) Normal escarpment5) Subdued escarpment6) Orthoclinal slopeThe continuous TOBIA index ranges from -1 to 1 (parallel orientation)The structure TOBIA should be calculated with can be set either distributed (through dip direction and dip grids, in degrees!), or globally using integers (dip and dip direction, in degrees!). The tool creates a TOBIA class integer grid, and (optionally) a continuous TOBIA index grid.Reference: <a href="http://www.sciencedirect.com/science/article/pii/S009830040000011X">Meentemeyer R.
