IsolineGen

Generate smooth contour isolines from scattered elevation point data

Geospatial AIFree

IsolineGen interpolates scattered survey points into continuous isoline contour maps using kriging, natural neighbor, and TIN methods. The tool automatically selects contour intervals based on terrain relief and map scale, applying Tanaka illuminated contours for enhanced terrain perception. Hydrological enforcement ensures contour lines respect drainage networks by adjusting interpolation near stream channels.
