Comparing Surfer and QGIS

Quite often people will ask, “What are the differences between Surfer and QGIS?” Below is a comparison of the main features and functionality of each program. Surfer, as you may know, provides 2D and 3D contouring complete with surface mapping software. QGIS has an assortment of plugins, and we haven’t been able to review them all. I encourage you review and let me know if there is any missing information. As new information comes in, I’ll be sure to update the matrix below.

Beyond the actual functionality, another difference between Surfer and QGIS is the development models. Surfer is a commercially developed program whereas QGIS is open source and is developed by a community of contributors. While it’s difficult to quantify, I believe it’s worth mentioning the pros and cons, according to me, associated with our commercial software model and QGIS’s open source model.
