POSC Specifications: Epicentre Version 3.0 | Logical Data Model |
NDT_DE9IM (C004, C151, C152) | (Express) |
A variation of the OpenGis specification for the Dimensionally Extended Nine-Intersection Model (DE-9IM). Each character in the string represents the maximum dimension (D, 0, 1, 2 or 3) of the intersection of the primary and secondary objects where "D" indicates disjoint, "0" indicates a point, "1" indicates a line, "2" indicates a surface and "3" indicates a volume. The characters are in the order of: PI-SI, PI-SB, PI-SE, PB-SI, PB-SB, PB-SE, PE-SI, PE-SB, PE-SE. Where P=Primary_object, S=Secondary_object, I=Interior, B=Boundary, E=exterior.
