Description:

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

* * * * * Attribute table * * * * * ( See the third screenshot below )

Interpolation (kd-tree searching mechanism)
• Type:
(1) Inverse Distance (IDW)
(2) Modified shepard
(3) Nearest neighbours
(4)Nature neighbours

Version 4.9
Review by Pet.Geologist

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.

Version 1.8
Review by Michael Heggen

a big disappointment - Where to start? How about I start with this: DO NOT BUY THIS. This is not a release-quality app. It is alpha quality (at best), and should be withdrawn from the app store as it does not do what it says it does. This is a new app with no reviews at all, so I took a chance and bought it. What I really did is take one for the team, because I paid ten bucks for the privilege of writing this review telling the rest of you not to buy this app. Lucky me…. 1) Documentation is very poor and in sub-standard English. It consists of 37 pages of screenshots with two or three sentences each, one of which is almost always "Following shown:" Here is an example: This report describe the base operation on this software. Feedback ,We really hope that you can help us to improve this software,If you have any advice or suggestions please send email to us. Thank you very much for read it. 2) It doesn't do what it says. The description specifically says that the app can draw contours. To me, this means I should be able to import a raster image and DRAW contour lines on it. Unfortunately, all you can do is key in data points in a table (or import them from a CSV file). 3) Weird interface. To perform any basic function (like creating a contour layer), you have to right-click on the layer you want and then choose from a two-level submenu. 4) When attempting to change data points in the contour table, the app crashes when I click Ok. Every time. 5) When attempting to draw lines (not contours—just lines), there is no apparent way to get the draw tool to stop drawing. I have no idea how one is supposed to edit lines one has drawn. 6) The only file format supported for export is PNG. The only export option is to specify the width of the image and the filename. And to top things off, it doesn't export all of the layers. Maybe subsequent versions will be an improvement. Actually, I know they will be an improvement, because it can't get much worse.
