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
(5) RBF-ML
(6) Simple kriging
(7) Ordinary kriging
• Get point M data from attribute table for interpolation

• Grid transformation
• Grid math
• Grid extracting
• Grid function
• Grid blank

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

• 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)

• 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.

No Support

The software has great potential as it appears to be modeled after MacGridzo - a great OS9 contouring package. But, unfortunately, the only time I heard from the developer was before I purchased the software. Afterwards, after requesting help twice, no response. Disappointing.

Easy Contour rocks

I’m a geologist and I’ve looked for a long time for a decent contouring package that runs on a Mac. This is it.

It takes a little experimentation to figure out how to use it, but this program is quite capable. Yesterday I fed it
70,000 data points and it never balked. It politely created an accurate color-filled contour map with appropriately
labeled contours. The application has cartographic smarts too. I can overlay ArcGIS shape files of data on top
of the contours. I can also export maps as ArcInfo-compatible grids or AutoCad-compatible DXF files.

Kudos to the programmer for an excellent job of coding. I’ve used much more expensive contouring packages
that are not as capable as this program.

Nice initial effort but needs a lot of more tools and input formats

This is a nice basic contour software but needs a lot more features (georeferenced coordinate systems (ITRF, WGS84, UTM projection grid, area, perimeter, closure error, catch basin drainage map, etc), tools (COGO, new points, close polygon, set area, etc) and data input/output format support (DWG, KML, SHP, XLSX EXCEL worksheets, etc). Even the icon bar can not be customized yet, nor can the minor and major contour’s intervals can be set..

It is a good first effort so hopefully the author will implement all these missing features soon and make it a great contouring package
