Easy Contour

Easy Contour is a 3D visualization, contouring and surface modeling package that runs under Mac. It is used for terrain modeling, landscape visualization, surface analysis, contour mapping, 3D mapping, gridding, and much more.

Feature layer (point, line, and polygon layer)
• Add and edit points, lines, or polygons
• Render type: Simple, ClassBreak, Categories (according to the attribute table)
• Symbol layer type of point layer: Simple marker, Character marker (You can enter any character)
• Fill type of polygon layer: Simple, Gradient, Hatch, Picture

Interpolation (kd-tree searching mechanism)
• Type:
(1) Inverse Distance (IDW)
(2) Modified shepard
(3) Nearest neighbours
(4)Nature neighbours
(4) RBF-QNN
(5) RBF-ML
(6) Simple kriging
(7) Ordinary kriging
• Get point M data from attribute table for interpolation

Contour
• Grid transformation
• Grid math
• Grid extracting
• Grid function
• Grid blank
• Grid report

Projection system
• Geographic systems, Projected systems
• Projection transformation

Voronoi and Delaunay triangle
• Build voronoi polygons according to points, and get to the points of attributes
• Build Delaunay triangle according to points, and add attributes

Import
• Scatter plot (*.txt, *.dat, *.csv, *.tab) (The points coordinates and attributes are automatically added to attribute table while importing Text file.)
• ESRI Shapefile
• Binary golden software grid 6/7 (*.grd)
• ASC Arc/Info ASCII Grid (*.asc, *.aig, *.agr, *.grd)
• USGS DEM (*.dem)
• DXF (*.dxf)

Export
• ESRI Shapefile (*.shp, *.shx, *.dbf, *.prj)
• Image (*.pdf (vector), *.jpg, *.png, *.tiff)
• DXF (*.dxf)
When export contour lines, you can put the contour value on elevation.
• GRD Surfer 7 Binary Grid (*.grd)
• ASC Arc/Info ASCII Grid (*.asc, *.aig, *.agr, *.grd)
• KML (*.kml)
