QGIS 2.5D Functionality

When I went into the office today, I had to write an amazing blog about the QGIS 2.5D functionality and how it was the beginning of QGIS’ journey into the 3rd dimension. Only I can’t, because Anita Graser, the author of “Learning QGIS 2.0” and owner of the Free and open source ramblings blog beat...

Web Mapping, Part 2

It’s as easy as 1, 2, built. In my last article in this series (December 2015), I briefly discuss the essence of what a web map is and the basic components. This part looks at the easy web mapping solutions that I briefly touch on in the last piece. I then discuss and provide the...

At the time I fudged some wind turbines as it was impossible to import models. Furthermore, I avoided too much detail as any imagery would look...

Recreating the Ordnance Survey Explorer Maps with Open Data

The holy grail for many (UK) map users is the Ordnance Survey 1:25,000 scale “Explorer” map. Not only are they easy to read due to the fantastic cartography used, but they also have information which is hard to source such as public rights of way, National Trust & Woodland Trust sites, even wind farms.
