Ordnance Survey OpenData In QGIS 3: Part 4

At the end of my previous post on this topic, I left you with this map of the area around the mountain of Blaven (Gaelic Bla Bheinn) on the Isle of Skye: That concluded a three-part tutorial on using Ordnance Survey OpenData products in QGIS mapping software. (To go to the start of the series, … Continue reading Ordnance Survey OpenData In QGIS 3: Part 4

Ordnance Survey OpenData In QGIS 3: Part 3

I finish my last post about using Ordnance Survey OpenData in QGIS having produced this map of the area around Blaven, on the Isle of Skye: It’s tinted for height, shaded and marked up with contours to emphasize landforms, and has features such as surface water, coastline, roads and buildings added. Now it needs some … Continue reading Ordnance Survey OpenData In QGIS 3: Part 3

Ordnance Survey OpenData In QGIS 3: Part 2

So, by the end of my previous post on this topic, I’d used Ordnance Survey OpenData products in QGIS to produce a nice smooth depiction of the topography of Ordnance Survey grid square NG, tinted to show height and shaded to show relief.

Which I did—it appeared in TAC25, Nov ’95-Jan ’96. They were called ViewFinder Panoramas, they’d been created by Jonathan de Ferranti, and in my opinion … Continue reading PeakFinder

Which Place Gets The Most Daylight?

So this puzzle isn’t about sunshine (the amount of time the sun shines from a clear sky), or even about the intensity of sunlight (which decreases with increasing latitude), but about cumulative daylight—the length of time between sunrise and sunset in a given place, added up over the course of a year.* It’s a surprisingly … Continue reading Which Place Gets The Most Daylight?

Book Collector

When you have more than 4000 books scattered around the house, it gets difficult to find the one you’re looking for. Especially if you’re hunting for a short story and you can’t quite remember which book you read it in. This used to happen a lot, chez Oikofuge. But not any more. Book Collector is … Continue reading Book Collector
