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.

Missing Contour Layer under OSX 10.9

Though 10.9 is listed as compatible, versions 5.0 through 5.2 have continued to exhibit the inability to Add a Contour Layer for processing imported scatter data. The Contour icon in the menu bar is all missing. In addition, Force Quit and the Activity Monitor display only the EasyContour icon. Without the program name, the AM search cannot single-out Easy Contour.

Attempted to load a small ASCII .grd. Though Easy Contour recognized the file type, the file import appeared to hang. CPU stopped accumulating.

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.
