Complex Data Made Clear with Surfer

Complex Data Made Clear with Surfer

Our customers do incredible things! This week, I’m pleased to present another customer story. Dr. Richard Koehler, founder of Visual Data Analytics, uses Surfer to visualize complex marine data.

Marine environments can be tricky as data is typically collected over time. This results in large, multi-variate datasets which contain a wealth of information; however, traditional 2D and 3D visualization methods don’t communicate this information in a clear manner.

Understanding Coordinate Systems in Surfer

A topic in which we receive many customer inquiries is coordinate systems. I recently reviewed the individual questions as they pertain to Surfer, and many users are confused about where to change the coordinate system information, what to set it to, or what order to perform the steps. To shed some light on this very important component of map making, this blog will address these questions.

I recently had a question where a user needed to convert the XY coordinates of the map from lat/lon (degrees) into meters, so that they could add a profile to the map showing meters as the Distance units instead of degrees.

Gotta Plot 'em All!

Gotta Plot 'em All!

A wild Zubat appeared!

Last month was the launch of Pokemon GO, an augmented reality (AR) mobile game from Niantic, the makers of the popular AR game Ingress. I must confess I've caught the fever, but I haven't caught them all! I am admittedly not a 'gamer,' and this is my first experience with Pokemon. I'm no Pokemaster, but I have fun catching new Pokemon while walking around downtown Golden on my lunch breaks, around the park, or around Denver. I haven't tried my luck battling at any Gyms yet, so I guess you could call me a casual player.

How to show areas of overlap of two contour maps in Surfer 13

I communicated with a user recently who wanted to find the area of overlap of one specific contour line on one contour map with a specific contour line on another contour map. In his case the first contour map was temperature and the second was rainfall. He wanted to find the area where temperature was above one value and rainfall was above another value. Whether this was for agriculture or for some other purpose I’m not sure, but it got me thinking that there could be many applications for a use like this. For example, you may have a contour map of density of one endangered species, and another for a second endangered species, and you’re trying to identify high populations of both in order to create a wildlife refuge. Or maybe you have population of people on one contour map and energy use on another, and you want to find areas with low population but high energy usage so you can send conservationists into that area to notify the population of smart practices. The uses are endless!

So that said, below are the steps to determine the area where two specific contour levels on two different maps intersect. In this case, I’ll be finding the area in Colorado where temperature is greater than 12oC and precipitation is less than 50 hundredths of inches, which may indicate an area that is more prone to wildfires. The data used in this article was obtained from NOAA. January 2015 – November 2015 data was averaged and then gridded in order to produce the attached grids.

Modeling Groundwater Resources in Surfer

Modeling Groundwater Resources in Surfer

We are pleased to present another story detailing the application of Surfer in the industry.

This story comes from former Golden Software team member, Jared King, who now works as a hydrogeologist for Knight Piésold. Mr. King and the Knight Piésold team were tasked to characterize groundwater resources for a potential mining area. An important component of the mining process, water is used for mineral processing, metal recovery, dust mitigation, and the basic needs for on-site workers. Even more importantly, a thorough understanding of groundwater resources is a major factor in understanding the environmental impact of the mine on those resources.
