Atlas Would Be Jealous
In this post we look at creating a map series of similarly formatted maps. Here a GIS Central we recently started some work looking at the carrying capacity of cruise ships in Fiordland. There was some field work involved so to carry out some of the work, the good people at Pacific Eco-Logic needed some maps, […]
Finding the Way in Wadi Hadhramaut
We look at georeferencing a map from Freya Stark’s travels in south Yemen, 1936, in this post. So I’m a bit of reader in my (ahem) spare time and am firmly in the camp of Scout from To Kill a Mockingbird, who said, “…I never loved to read. One does not love breathing.” Of course […]
Setting Free the Map
Some places make for challenging map making. In this post we look at one way of working with the dragonfly data to produce a (hopefully) effective map. In a previous post we looked at massaging some spatial data from Wallis and Futuna to make them mappable. One of the end results of those data was […]
Those Unformatted Dragonflies Again…
Analysis and mapping is almost always preceded by time spent getting data ready to be mapped. In this post we cover an instance of reformatting some raw spatial data so that they can be used for mapping. Over the years, there have been a few posts about dragonflies of the Pacific, from using a smartphone app […]
Interesting Election Maps
This post looks at some alternative mappings of the recent 2020 US presidential election Election coverage seems to love maps, but they can sometimes misrepresent outcomes as we’ve seen previously. The GIS Blog tries (but often doesn’t succeed) to be apolitical, even though there’s plenty of force behind the idea that political views have a […]
The Path of Least Resistance
In this guest post, Joesph Zooneveld takes us through least cost path mapping to find a mountains to sea biodiversity corridor of native bush. In a recent GIS course at Lincoln University, I was tasked to find a spatial problem and then solve it using a GIS analysis. Being interested in conservation and biodiversity, I […]
ArcGIS and Google Maps/Google Earth
In this guest post, ERST607 student Aimily Li gives us some detail on how to export data from Google Maps and Google Earth – useful stuff! Introduction Sometimes in our daily life, the GIS data we collect may come from some other programs like Google Maps and Google Earth. These applications are more commonly used […]
Mad Science 101: Vaporising the Hero
In this guest post, ERST607 student Callum Mclean delves into the using GIS to estimate solar radiation. Take it away, Callum… (updated 14 October for clarity.) An Introduction to the weirdly complex world of solar power As a well-informed evildoer you might have heard we are in the midst of a rather problematic climate situation. […]
Deleting Smokers – Part 3 – Progress!
In Part 3 of a series on developing a Python script, some progress is detailed. A short data-massaging script helps prepare the input data for the main script. In this ongoing series about developing a Python script for some analysis, we first covered what the script needs to do and then also covered some data issues. […]
Deleting Smokers – Part 2
Part 2 of this series looks at refining our script pseudo-code to get input data prepped for further analysis Way back when the dinosaurs roamed the earth, we saw the first post in this series on developing a Python script for some analysis. With Python being the topic of the moment in the current GIS course, […]
