Golden Software's Mapping Software Lineup Put To The Test

Users often combine Golden Software's mapping and griding software products to produce their final project. In the summer of 2007, a study was conducted by Dr. Richard Crawford of the Prince William Sound Science Center (PWSSC) in conjunction with the Valdez Fisheries Development Association to develop a tool to enhance the evaluation of fish abundance with their commercial-grade echo sounders. The goal was to maximize the harvesting of brood stock at the Solomon Gulch Hatchery. For their analysis, PWSSC used a combination of Surfer, Voxler, and Grapher to complete the study of Enhancing in-house assessment of pink salmon returns at Solomon Gulch Hatchery in Alaska. See the full report for additional information.

Numerically Verifying Grid Results Through Surfer's Graphing Software

You’ve used Surfer mapping software to grid your data and created a great looking map. You put it in the final report for your presentation. And you think, that was easy and I’m all done now. And then someone asks you, how do you know that map is accurate? You start to wonder. How do I know if it is correct? Is there any way to verify the gridding? If the grid file matches the original data, then I could confidently say the map is correct. But, how do I know if the grid file matches the data?

In the previous blog, we discussed visually inspecting a grid to see if the grid created is a good representation of the original data. To do this, we compared a contour map from the grid to a classed post map from the data.

Creating Contour and 3D Maps With Surfer from Downloaded Images

One of the new features in the Surfer mapping software that hasn’t gotten a lot of mention is the ability to download imagery as grids. Most of you may know that Surfer can connect directly to WMS servers and download georeferenced images directly into your maps as base layers. You can download aerial photographs, orthoimagery, shaded topographic images, scanned USGS maps, images showing geological bedrock, etc.  However, did you know you can also download imagery as grid files and use them to create contours or other grid-based maps?

You can download images as grids from WMS servers using either the Grid | Grid from Server command, or by clicking the Download button in the Open Grid dialog when creating a grid-based map. The difference is that the Grid | Grid from Server command downloads the image as a grid file directly to your hard drive so you can use it later on (e.g. for blanking) or in multiple maps.
