| Abstract | The curve, surfaces, and volumes of the map information measurement can be so complex that the ordinary measurements become meaning less. There is a way to measure the degree of complexity of spatial information by evaluating how fast length, or surface, or volume increases if we measure with respect to smaller and smaller scales. Formula of calculation of Entropy is created for calculate the distribution of geospatial information with quantitative measurement approach. Fractal Dimension is the useful parameter for calculate the complexity of GIS map content. It is the most popular parameter and more accurate for explaining and describing the natural textures or natural phenomena i.e. waterbody (river and lake) and settlement area (urbanization). The calculation of complexity of the man-made objects on the map i.e. urban infrastructure and urban parcel can also be implemented by this parameter. The experiments are performed for checking the stabilization in transformation of spatial information from changing scales and applied Mathematical Morphology properties as the tools for investigate the difference after transformation by using the self-similarity properties of Fractal Dimension and Entropy based measurement. Formula of calculation of Fractal Dimension is created for calculate the complexity of goespatial information without disturbance in transformation of scales. |
