Using Surfer to evaluate and improve my vegetable garden

With summer rapidly coming to a close, it's time to take stock of what worked well and what didn't for my garden. This is my first experience with gardening, so there's plenty I can improve upon for next season. I used Surfer to create a to-scale plan of what my garden looked like this year:   As you can see, there's a lot of crowding in the t...

Calculating the Average Contaminant Plume Concentration in Surfer 14

I recently ran across an article that was written by an experienced Surfer user, Joseph A. Ricker. The article, A Practical Method to Evaluate Ground Water Contaminant Plume Stability , provides a workflow for determining the average contaminant plume concentration that I thought our Surfer community may find interesting. Below, I've summarized the...

Calculate Slope for a Site Suitability Model

I recently received a call from one of our Surfer users who was trying to create a site suitability model for a new manufacturing development. The user needed to find areas within the proposed site where the slope was under 10 degrees. The site suitability model required specific slope to be respected; the areas that were under the threshold criteria of 10% would be considered potential locations within the site to locate the new development.

A site suitability model can be easily developed in Surfer by creating a slope grid from a digital elevation model or DEM for the area, masking the slope grid to the site boundary, and creating a contour map that highlights the areas that meet the 10% or under criteria. Since this is such an interesting workflow, I thought it would be a great topic to blog about it so others in the Surfer community could benefit from seeing the approach.

Creating elevation contours within a house footprint from paper notes

Golden Software’s Surfer program can be used in so many applied-science industries for so many different uses, I sometimes forget that it is equally applicable to more business or art-oriented fields. I had a user contact me recently with the following request (paraphrased):

“I have a paper copy of the blueprint of a house, and on it I’ve written elevation measurements that I collected while surveying on the premises. I also have a DXF file of the floorplan of the house. How can I create elevation contours in Surfer and limit them to the shape of the house?”
