Trend

Analyst simulates the trends of spatial distribution and the regional change using the mathematical curved surface. It calculates a mathematical curved surface to simulate the trend of regional change. Physically, it simulates the regular pattern of the distribution of the geographical elements to display the spatial and regional trend of change of the geographical elements by regression principle.

Trend Analyst can be used to simulate the spatially regular pattern of distribution of resource, environment, population and economic factor. The lower order polynomial can be used to express the smaller spatial data; the higher order polynomial can be used to express the more complex spatial data.
