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.

Maps and Map Layers in Surfer Mapping Software: The Source Coordinate System vs. the Target Coordinate System

Maps and Map Layers in Surfer Mapping Software: The Source Coordinate System vs. the Target Coordinate System

Since Surfer 10, users have been able to create maps using layers that contain data from different coordinate systems and reproject the layers to the desired coordinate system on the fly. This valuable feature has streamlined workflows, eliminating the need to transform all data to the same coordinate system before using it to create multi-layered maps. For an example, see the sample file CoordinateSystems.srf, located by default at C:\\Program Files\\Golden Software\\Surfer 12\\Samples. Let's take a look at this powerful component of Surfer's 3D Mapping software!

Mapping Challenge: Use Golden Software's Mapping Software to Survive A Zombie Apocalypse

Mapping Challenge: Use Golden Software's Mapping Software to Survive A Zombie Apocalypse

I ran across a recent mapping challenge while perusing reddit.com's GIS community, and I wanted to extend the challenge to Golden Software users! This challenge asks users to submit a map that would help someone survive the inevitable zombie apocalypse. The challenger also requests steps used to create the map. The challenge is presented as a fun way to help others learn mapping software.

Golden Software documentation writer Zach whipped up a submission today. His map was created using a combination of MapViewer 8 and the eagerly anticipated Surfer 13! Zach's map uses real city population density data from the Colorado Front Range presented as a proportionally-sized post layer, his own calculated zombie population data displayed as an image layer, a base layer downloaded from an online server, and a contour layer created from manipulated data from a grid downloaded from an online server (a new Surfer 13 feature). Stay tuned for future blog post detailing how to recreate this map!
