SuperGeo Technologies, the leading global provider of complete GIS software and solutions, announces that SuperGIS Spatial Analyst 2 supports Thiessen Polygon.
Thiessen Polygon is an analyst method usually utilized to estimate the average rainfall, average run-off in a certain area, etc. The feature of Thiessen Polygon is to use the specified sample points to divide a flat surface into polygons. Each polygon only contains one sample point. The distance between any location inside the polygon and the sample point is closer than the distance between that location and other sample points in other polygons.
With the analyst method, analysts can estimate the average volume in each area more accurately when they do not have enough observation points. Therefore, the estimated results can be the references for the advanced analysis and applications.
