An anisotropic map is a texture that controls the shape of the specular highlights from real-time lights, often used for hair shading. Anisotropic highlights are characterized by long directional strokes, instead of the typical circular shape.
The texture is usually called a Flow map which is very similar in concept to a normal map, except instead of controlling surface normals, it distorts the specular highlight in specific directions across the surface.
