Edit Contour Lines with Surfer

The ability to edit contour lines is one of Surfer’s most highly requested features, and we are pleased to report this feature is available in the latest release!

A contour map is a two-dimensional representation of a surface where the surface is represented by contour lines. A contour line connects points of equal elevation, and the distance between contour lines represents the relative slope of the surface.

Saving Time for both New & Experienced Users - Surfer's Map Wizard

An exciting new Surfer feature is the Map Wizard. Create numerous maps in as little as three steps. The wizard is a great tool for Surfer newbies as it steps through the map creation process from raw data to interpolated grid to final map. More experienced Surfer users appreciate the ability to create multiple maps at once, and everyone benefits from the Data Preview window so you no longer open the incorrect file.

Step 1: Select Your Data – Select the data, grid, base map, or image file to create your map.

Georeference an Image in Surfer

There are many ways to customize and enhance maps. One popular enhancement is including images such as satellite imagery, aerial photographs, or historical maps. Images provide additional information and context for the map. In order to spatially relate the image with the other geographic data sources in a map, the image must be georeferenced.

Georeferencing an image is the process of assigning real-world coordinates to each pixel of the image. The latest release of Surfer can georeference images using three or more control points. Below I will step you through some of the main georeferencing features, but for more detailed instructions on how to georeferenced an image of your own, check out our knowledge base article, How can I georeferenced (assign coordinates to) an image base map in Surfer?

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?”
