Vector Makes Its Mark

A cornucopia of vector tools help with some marking While both students and academics are celebrating the end of another semester, it may well be a bit short-lived. Poor students have exams to cope with and poor academics have scads of marking to endure. One of the GIS courses has recently done a project on […]

Model Behaviour

Using ModelBuilder to automate a repetitive task No question – GIS can certainly be frustrating. And it doesn’t get any less frustrating as you get better; the problems just morph into more complex things. Lately, I’ve been wrestling with a particularly vexing problem that on the surface should have been easy but in practice made […]

Getting Maps into Reports

We quickly cover how best to incorporate map layouts into written reports In this special edition, I’ll cover how you can better incorporate your maps into things like reports or theses, or wherever they need to end up. We often focus on stand along maps where everything that is needed. Maybe they end up as […]

Bi(variate) Curious

Using Bivariate Symbology on a map of housing prices We’ve been looking at different mapping strategies lately and this time we’ll look at an uncommon one, uncommon enough that people are likely to be curious about how it works. I will admit that I, too, have been curious, having never really used it before. The […]

The View from Forbes

As most everyone will be aware, the Burns Building is slowly being demolished. I doubt that many will mourn its passing, but I’m no architectural critic. What I can be critical about is views. In my new digs in far reaching Forbistan (Ed. you mean the Forbes Building, right?), I was checking out the view […]

Location, Location, Location

Adding spreadsheet data to a map and displaying house price index data They say that the three most important things in real estate are location, location, location. I always trot that one out at the beginning of a semester and extend it to most everything we do at Lincoln, but in this post we’ll look […]

Global Phosphorus Blooms

Three different ways of mapping some dissolved reactive phosphorus data are covered. Some of our recent work in pulling together a set of global datasets is beginning to bear fruit. Over the next few posts, I’ll go into excruciating detail on how the datasets were pulled together and the analysis results mapped. Along with nitrogen, […]

Lines on the Map

From space, one could hardly tell that what we see above is one of the most divisive, fraught areas on the planet. When we add the country boundaries, the familiar shapes of the Middle East serve as a reminder: I’m going to stray into some difficult territory in this post, and not without a healthy […]

Fires Lines

A quick and easy request is handled with Select by Location As we go to press, a fire rages on the Port Hills, reminding many of a similar event in 2017. Just today, I had a quick request from LU student services to get a quick idea of which roads were close to the fire […]

Analyst, know thy coordinates

Recognising different coordinate systems can be helpful in speeding up your work. It’s said that the Temple of Apollo at Delphi was inscribed with three key maxims for a good life, one of which was “Know Thyself”. This is, of course, very good advice. For the GIS analyst, knowing yourself helps to know when to […]
