Classification is the most common method for information extraction from remotely sensed images. Conventional classification methods are mostly based on spectral information. While particularly in high spatial resolution images, spatial relationships between neighboring pixels used to discriminate between different land-cover classes in human interpretation. In different research methods for quantification of image texture and use it to create separation between classes is provided. Considering the variety of formulation and adjustable parameters of texture quantization methods, huge number of texture features could be generated. Each feature has specific ability to discriminate special classes. In this paper a new method based on spectral index formulation proposed to generate Spatial Indices from textural features. Best pairs of textural features selected and Spatial Indices using them will be generated. Generated Spatial Indices are good abstract of textural feature space to use in classification procedure. This method could led to better classification results in a direct and none international solution.
