Surfer 13 New Feature Series: Graticules

In the coming weeks, I'll be introducing some of the new features in Surfer 13. The first feature discussed in this series is the addition of graticules!

A graticule is a network of lines representing the Earth's parallels of latitude and meridians of longitude. While a graticule represents lines or latitude and longitude, a map-grid represents lines in other units, such as meters or feet. A graticule or map-grid can be added to a map by selecting the map and clicking the Map | Add | Graticule command. Graticules and map-grids are a great way to add more context to your maps. Display your axes in the units of your data (feet, meters, etc.), and add a graticule to show latitude and longitude values too! Do your clients need a map displayed in multiple units? Project your map in UTM meters, but display a grid in feet!

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

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!

Using Didger and MapViewer to Build a Site Map

I recently took a trip to Tennessee to attend the 14th annual Bonnaroo Music and Arts Festival. The festival takes place on a 700-acre farm in Manchester, TN. In addition to music and art installations, Bonnaroo has campgrounds organized by pods, a cinema tent, a comedy theater, and more! Upon arrival to the festival, attendees are given a map of the festival site. With stage names that include What Stage, Which Stage, This Tent, That Tent, and The Other Tent, the map is a necessary tool for many attendees! For this post, I used a combination of Didger 5 and MapViewer 8 to recreate the map and export it to KML to display in Google Earth.

To begin, I downloaded the PDF version of Bonnaroo's map (pictured below) from their website.

World Oceans Day 2015

Tuesday, June 8, was the 7th annual World Oceans Day since its official recognition by the United Nations in December of 2008. The yearly observance is dedicated to raising awareness about the importance of the world's oceans and their products, celebrating the natural beauty of the oceans, and inspiring others to take action on behalf of the seas.

To celebrate World Oceans Day 2015, Google updated their Oceans Street View collection with stunning underwater images of oceans around the world. Images were collected by the XL Catlin Seaview Survey, a project for scientists and the public to document the health of coral reefs. The images, collected since 2012, will be used as a baseline to monitor the reefs' health over time. Over 100,000 GPS-located images have already been collected by the SVII camera. Additionally, the images are being analyzed, and the data is available in the XL Catlin Global Reef Record.
